Iron-blooded general Zhang Wannian

In 1995, General Zhang Wannian played chess during the break of the National People’s Congress.

"Sixty years!" Zhang Wannian, a veteran who participated in the "Four Guarantees of Linjiang" battle, and Yu Ruomu, the wife of Chen Yun, the old superior, got together at the premiere of the TV series "Chen Yun in Linjiang", which was filled with emotion.

Zhang Wannian, former vice chairman of the Central Military Commission, died in Beijing on January 14th.

In August 1944, 16-year-old Zhang Wannian joined the Eighth Route Army and was awarded the rank of general in May 1993. He won the Third Class Medal of Liberation and made great contributions five times.

war of liberation

Tashan blocking war fought fiercely for 6 days and nights

Xiong Guangkai, former deputy chief of staff of the People’s Liberation Army, recalled his old leader Zhang Wannian in an article. He wrote that the Tashan blocking war that took place in October 1948 was a rare defensive war in the history of our army in terms of scale, time and cruelty. Zhang Wannian took part in a bloody battle for 6 days and nights as the chief of communications at that time, so Tashan became a haunting place in Zhang Wannian’s life.

"Although there is a word" mountain "in the place name of Tashan, it is actually only some hills with little ups and downs, not real" mountains ",which cannot constitute a dangerous terrain for sticking to defense, but Zhang Wannian and his comrades-in-arms just ensured the overall victory of the Jinzhou campaign without danger." Xiong Guangkai wrote.

Counter-attack against Vietnam

Deng Xiaoping praised him.

When the self-defense counterattack started, Zhang Wannian was the "Iron Strategist" teacher. He was familiar with the terrain and the characteristics of the enemy. The enemy was both afraid and angry, and he played the slogan "Destroy 127 (Division) and capture Zhang Wannian alive".

In 1968, Zhang Wannian, then the chief of the operations department of the Guangzhou Military Region, suddenly went to into thin air. His wife only knew that he had gone on a top-secret mission, but she didn’t know where he had gone. It turns out that Zhang Wannian and nine other people went to Vietnam to learn from the experience of the War of Resistance Against America on the orders of the Central Military Commission. A year later, Zhang Wannian came back and got malaria in Vietnam. His weight dropped sharply from 160 kg to 120 kg, and his wife almost didn’t recognize him. However, Zhang Wannian is also considered as glad you came, and his accumulated experience during his stay in Vietnam provided a good reference for the Vietnam war.

In December 1978, the Central Military Commission ordered the 43rd Army to take part in the self-defense counterattack on the Sino-Vietnamese border, and appointed Zhang Wannian as the deputy commander of the 43rd Army and the division commander of the 127th Division. Zhang Wannian fought four wars in succession in Zhima and Luping areas outside lang son, a Vietnamese military town, and won four victories in four wars.

At 19: 00 on March 3, 1979, Zhang Wannian received instructions from the head of the army: because the troops attacking a city had not yet arrived at the designated position, the time for the general attack on the city was changed to 7: 00 a.m. on the 4th. The 2nd Battalion and Rocket Battalion of a regiment preparing to cross the river were immediately ordered to stop their operations.

Zhang Wannian is in a dilemma. The troops behind stopped crossing the river, and the two battalions that had already crossed the river were alone. If the other army suddenly comes under heavy pressure and attacks at night, the two battalions will fight against each other. If you withdraw, once the other side reoccupied the other side of the river and strengthened its defense, it will pay a higher price to cross the river again.

Facing the most severe test since the war, Zhang Wannian smoked one cigarette after another. He quickly calmed himself down, repeatedly considered the gains and losses, and quickly made up his mind, and reported it to the head of the army: take the attack as the defense, "guide the west", confuse the other side’s nerves, and disintegrate the attack that the other side’s heavy troops may have on our troops crossing the river in advance.

This action worked that night. The other side was blinded by the "abnormal activities" of the artillery and infantry of the People’s Liberation Army, and rushed to make an emergency transfer overnight, which was too busy to take care of the ferry controlled by the "iron strategist". Zhang Wannian finally breathed a sigh of relief. That night, he smoked seven packs of cigarettes!

On May 12, 1979, the People’s Liberation Army Daily published a long interview "Kill the chicken with a knife-Zhang Wannian, the teacher, talks about the problem of concentrating troops on the war of annihilation", and Deng Xiaoping also praised him.

When Hong Kong and Macao returned to China,

Guide the troops to settle in

In November 1992, Zhang Wannian served as the leader of the preparatory work for the Hong Kong Garrison, and organized and guided the negotiations on the handover of Hong Kong’s defense, the formation of troops stationed in Hong Kong, and the legal preparations for the Hong Kong Garrison. On July 1, 1997, he accompanied Jiang Zemin and other central leaders to attend the handover ceremony of Hong Kong’s political power between China and Britain. Using the experience of Hong Kong garrison preparation, Zhang Wannian once again guided Macao garrison preparation, and on December 19, 1999, on behalf of the Central Military Commission, he went to Zhuhai to bid farewell to the troops stationed in Macao.

In November, 2002, at the handover meeting of new and old comrades of the Military Commission, Zhang Wannian, after reviewing the 10-year history and feelings of the Military Commission, said with deep affection: "As a veteran, nearly 60 years of military service came to an end today. Looking back on the passionate years, my heart is still full of lofty sentiments. Here, I would also like to encourage myself with four old sayings:’ Be worthy of the Party in the upper class, be worthy of the soldiers in the lower class, do your best and die’! I have retired and will continue to practice hard all my life. "

After retirement

Former honorary chairman of mountaineering association.

Zhang Wannian once compiled his daily life after retirement into "Song of the Day": "Get up early and do morning exercises, and suck the breath of heaven and earth; Read freely and cast noble sentiments; Take a walk in the garden and enjoy the natural beauty; Reading articles and newspapers, watching the world trend … "

After retirement, General Zhang likes to climb mountains, and has been re-elected as honorary chairman of chinese mountaineering association for many times. When meeting with the climbers of Mount Everest, General Zhang Wannian kindly said to the Tibetan mountaineer Nima, "I have seen you on TV. You are the one who unfurled the five-star red flag on the top of Mount Everest."

The Chinese ambassador to Japan lodged a solemn protest with the Japanese government over the discharge of nuclear polluted water from Fukushima.

  Xinhua News Agency, Tokyo, August 24th-China’s ambassador to Japan, Wu Jianghao, lodged a solemn protest with Japan’s Deputy Foreign Affairs Minister Masayoshi Okano on the 24th, regarding Japan’s launching of the Fukushima nuclear polluted water discharge into the sea.

  Wu Jianghao said that today, Japan ignored strong doubts and opposition at home and abroad, shifted the risk of nuclear pollution to neighboring countries including China and the international community, put its own self-interest above the long-term well-being of people in the region and around the world, put the global marine environment and the health of all mankind as a dangerous bet, and insisted on officially launching the Fukushima nuclear pollution water discharge. China resolutely opposed this and once again lodged a solemn protest with Japan, demanding that Japan immediately stop this extremely selfish and irresponsible behavior.

  Wu Jianghao pointed out that the Fukushima nuclear accident is one of the most serious nuclear accidents in the world so far, causing a large amount of radioactive materials to leak. There is no precedent in the world to deal with it by discharging the sea, and there is still a lack of technology that has been tested by science and practice and proved to be "safe and harmless". Without fully demonstrating the long-term safety and reliability of the existing sea-discharging technology, gaining extensive understanding from all stakeholders, and establishing a complete international supervision and compensation mechanism, Japan insists on forcibly starting sea-discharging, which contains huge risks and unpredictable hazards.

  Wu Jianghao emphasized that the ocean is the blue home on which all mankind depends, and all countries have the obligation of international law to protect and preserve the marine environment. Japan has no right to decide to dump nuclear polluted water into the sea without authorization, and must bear full responsibility for the consequences caused by it. China seriously urges Japan to immediately stop discharging the sea, communicate honestly with its neighboring countries in a responsible manner, accept strict supervision by the international community, and effectively dispose of nuclear polluted water in a scientific, safe and transparent way. If Japan insists on doing it, it will bear long-term moral and legal responsibilities.

  Wu Jianghao pointed out that’s exclusion from the sea has aroused strong concerns of Japanese consumers about food safety. China government has always adhered to the people first, and must resolutely respond to people’s concerns and safeguard the marine environment, food safety and public health. It is natural and necessary for the China government to announce a total suspension of the import of Japanese aquatic products. The responsibility for this situation lies entirely with the Japanese side, which should reflect on itself.

  In recent years, the high-end luxury MPVs of major brands have been opened up, and the performance of independent brands in this market is particularly eye-catching. Under the background of different concepts and new energy routes, a number of models with great styles invariably use the "new three-piece set" such as refrigerator, color TV and sofa as the main configuration, supplemented by the concept of scenes, which has stirred up the once "stagnant water" of high-end MPVs.

  The market will always be rational after going through the hustle and bustle. In the face of the precipitation and cultivation of the next longer-term target consumers, where should the high-end new energy MPV go? In this level, the influential direction is given: Huawei, the head brand of the joint technology industry, is smart and intelligent. Not long ago, this heavy MPV, which was highly anticipated by Lantu, ushered in the launch of a brand-new model. It is the flagship product of the brand-new Lantu Dreamer: Dreamer’s flagship four-wheel drive Gankun version (hereinafter referred to as Dreamer’s Gankun version).

  It should be noted that the model we test drive this time is still an engineering prototype, and some functional adaptations have not been completed, and it is still being optimized, which will be different from the future commercial models in use.

  Before, we launched the question # Test Drive with Questions # in Weibo. Regarding the flagship Gankun version of the four-wheel drive of the brand-new Lantu Dreamer, the two most frequently asked questions were "What is the experience of the HarmonyOS cockpit?" And "What is the strength of Huawei Gankun A.0?" It can be seen that netizens are most concerned about Huawei’s whole family barrel, and Xiaobian also focused on the performance of this part.

  As for the intelligent cabin, the most important equipment of Harmony space is out of your sight. Although it is equipped with an 8295P chip and the version 4.2 is not "pure blood HarmonyOS", this car can basically be regarded as a dreamer’s adaptation on Huawei’s PAD, and the UI interface, basic applications and functions that can be realized are no different from those of Huawei’s "lineal" models. Smooth, fast, easy to get started, and supporting non-inductive circulation is a major feature. In use, only Xiaoyi Voice can occasionally fail to control the corresponding functions when executing commands.

  With regard to intelligent driving, Huawei Gankun ADS 3.0 is a complete system. The focus on dreamers is to adapt the electrical architecture and the car body, and the focus is on the open road intelligent driving scenes such as urban NCA and high-speed NCA. As far as our engineering prototype is concerned, the adaptation progress is actually quite high. In today’s 50-kilometer intelligent driving experience in Qianhai-Sanzhoutian, Shenzhen, there are only three times of prompting to take over in almost the most complicated driving environment in Shenzhen, and the basic ability is no different from that of ordinary drivers. And because of the intelligent parking functions such as AVP parking service assistance, APA automatic parking, RPA remote parking, etc., both of them seamlessly link all driving scenes, achieving its intelligent driving ability from parking space to parking space, saying that it is the intelligent driving ceiling at the same level, which is really worthwhile.

  Design originality is super high recognition.

  As the second model of Lantu brand, Dreamer Gankun’s 429,900-yuan plug-in hybrid model and 44.99-yuan pure electric model have firmly established the flagship model of Lantu brand in the future. In terms of identity, it is more inclined to business and high-quality groups, so it not only has a brand-new original design concept that is more obvious in business style, but also makes great efforts in functional design, and the details are very attentive.

Huawei's "Shuangzhi" empowers to test drive the brand-new Lantu Dreamer Gankun Edition.

  Its whole front is thick and square, with a sense of design and futurity. The three-dimensional closed middle net with longitudinal lines is the greatest feature, and the chrome plating on the whole face is extremely eye-catching. Lan Tu indicates that its brand-new front face is called "soaring up", which is composed of vertical grids symbolizing 34 provincial administrative regions. The bold shape collocation makes the front of the car highly recognizable and solemn.

Huawei's "Shuangzhi" empowers to test drive the brand-new Lantu Dreamer Gankun Edition.

  The shape of the light group at the top is similar to the regular shape of willow leaves, but it is connected with the light strip that traverses the upper part of the middle net, and with the Lantu logo that can be lit, the effect is amazing. On the light source, the new car is equipped with far and near split headlights, and the distribution of feather-like light cavities inside is very recognizable.

Huawei's "Shuangzhi" empowers to test drive the brand-new Lantu Dreamer Gankun Edition.

  The shape of the exterior rearview mirror stands on the door, and it uses the same color as the car body, which is very streamlined in shape. The two LED turn signal lights on the outside also add points to the shape. A small triangular window is made at the front of the side window, which is integrated with the whole side window glass, and is wrapped with a thick chrome-plated strip to increase the overall sense of the design, and at the same time, the driver’s vision is significantly enhanced.

Huawei's "Shuangzhi" empowers to test drive the brand-new Lantu Dreamer Gankun Edition.

  The double colors of the test drive are very business-style colors, and its side shape is square and burly, which is also very administrative. The side sliding door makes it look like a traditional MPV, and in order to make the side of the car have the same design sense as the front of the car, the waistline of the car body is very straight and regular, and the BC pillar is also highlighted in black, which makes the senior post very strong. In terms of body size, the length, width and height of the new car are 5315/1985/1800mm, and the wheelbase is 3200 mm.

Huawei's "Shuangzhi" empowers to test drive the brand-new Lantu Dreamer Gankun Edition.

  In order to create more riding space, its rear part is designed to be straight, and there are not too many design elements stacked. The only top tail shape is also very convergent, and the style is highly consistent with the front of the car. The synchronization of penetrating taillights appears at the rear. The matching of lines and colors is simpler and clearer than the front of the car. The shape of the rear part has a large tailgate window and a low tailgate opening, which is more in line with the conventional design of a big MPV.

  The 20-inch dense spoke rim once again adds a luxurious atmosphere to the side of the car, which seems to be easily reminiscent of ripples, and it will make people feel dizzy when rotating. The tire adopts the famous "Scorpion Tire" of Companion Endurance brand, with the size of 255/50R20, which emphasizes all-around and driving control.

  How easy is the cockpit blessed by HarmonyOS?

Huawei's "Shuangzhi" empowers to test drive the brand-new Lantu Dreamer Gankun Edition.

  When you enter the cockpit, you can feel the subversive cockpit change. The integrated screen connection used by the Lantu family before was cancelled, and the mainstream style of floating instrument+floating dual-screen central control was replaced. As for the IP station, it is still traditional. The regular T-shaped layout and color matching with curved surfaces look more consistent with the consistent impression of Lantu home. It is thick and has few physical buttons, and the functional layout is practical and concise. Very modern.

Huawei's "Shuangzhi" empowers to test drive the brand-new Lantu Dreamer Gankun Edition.

  As the "dashboard", this full LCD screen has a very accurate aspect ratio, and it will not be bothered by the display effect brought by the common "fish screen". At the same time, it is large enough, and the information displayed inside is still comprehensive, including navigation, energy, driving reminder, automatic assisted driving and other information. In addition, the W-HUD head-up display function of test drive is very rich in internal information, which can also effectively assist the driver to get the information.

Huawei's "Shuangzhi" empowers to test drive the brand-new Lantu Dreamer Gankun Edition.

  The steering wheel adopts a family-style three-spoke flat-bottomed design, and it has a strong sense of design. It uses a contrast package, which is very comfortable to hold. The function integrates the driving setting buttons and multimedia function buttons, which not only makes the buttons feel good, but also makes the function distribution more reasonable.

Huawei's "Shuangzhi" empowers to test drive the brand-new Lantu Dreamer Gankun Edition.

  As the interactive core of "Xiaoyao" intelligent interactive cockpit, it is a central 2.5K screen. And the CPU chip is equipped with Qualcomm Snapdragon 8295P chip, with the configuration of 5G network. From the hardware point of view, it is already an advanced equipment of the same level.

Huawei's "Shuangzhi" empowers to test drive the brand-new Lantu Dreamer Gankun Edition.

  There is no doubt that the system car is the latest version of HarmonyOS 4 system, not the latest "native HarmonyOS". This system is optimized for MPV models, but the interactive mode of the system is still the interactive logic of cards, trays and common functions, which mainly optimizes the visual effect on the original basis and tries to approach the operating experience of mobile phone tablet. In fact, it is worthy of the software and hardware foundation of HarmonyOS and 8295P, and its fluency can definitely rank among the top in the intelligent cockpit.

Huawei's "Shuangzhi" empowers to test drive the brand-new Lantu Dreamer Gankun Edition.

  As for its own functions, it is undoubtedly the top-level equipment, and the account login of the system has been further optimized. The operating car machine can use Bluetooth keys, faces and other login methods. Navigation is a customized Huawei petal map with functions such as charging pile search. The media source is equipped with a full set of Huawei programs, including music, listening to books, news, radio, video and other content. The entertainment function is basically the same as that of a Huawei tablet. If you still need applications, more than 200 additional Huawei applications for car applications can be loaded on the car.

Huawei's "Shuangzhi" empowers to test drive the brand-new Lantu Dreamer Gankun Edition.

  If you happen to use other equipment in HarmonyOS, then this cockpit can unlock more insensible information intercommunication ability for you. Navigation on and off the car can flow seamlessly without interrupting the call, and information such as music, videos and memos can flow synchronously automatically or by touching.

Huawei's "Shuangzhi" empowers to test drive the brand-new Lantu Dreamer Gankun Edition.

  The Xiaoyi voice system of the system can also quickly and accurately recognize instructions, interrupt or continuously recognize voice, and realize voice control switch of air conditioner, skylight and music in the car. Anyone who has used Huawei mobile phone knows its ability. After moving to the car in parallel, this part will naturally give you a top-level experience.

Huawei's "Shuangzhi" empowers to test drive the brand-new Lantu Dreamer Gankun Edition.

  On the driver assistance level, Dreamer Gankun Edition uses Huawei Gankun 3.0 system. The main hardware includes 27 intelligent sensing hardware such as 192-line laser radar, millimeter-wave radar and high-performance camera, which provides more than 20 active safety functions. Huawei’s Gankun ADS 3.0 is based on the BEV+GOD network architecture of Gankun ADS 2.0, and upgraded to the GOD (Universal Obstacle Recognition) network, realizing the leap-forward progress from "recognizing obstacles" to "understanding driving scenes" in depth.

Huawei's "Shuangzhi" empowers to test drive the brand-new Lantu Dreamer Gankun Edition.

  Compared with the common intelligent driving, this system has upgraded the new end-to-end large model architecture, and created an instinctive safety network, which can respond faster to emergencies and greatly reduce accidents; The effective range of forward AEB (automatic emergency braking) of CAS3.0 is 4-150km/h, and the braking speed can reach 120 km/h. When the braking distance is too short, the system can automatically avoid obstacles (eAES) and bypass while braking. According to Lan Tu, all its configurations are in line with the flagship of HarmonyOS Zhixing "Double 9".

Huawei's "Shuangzhi" empowers to test drive the brand-new Lantu Dreamer Gankun Edition.

  Gently push down the shift lever twice or press the smart driving key on the steering wheel to start the smart driving. Running for tens of kilometers in a place with complicated road conditions like Shenzhen can be done almost without human intervention. When the vehicle in front brakes or there is a traffic jam, the system can respond in advance, or give way or play games, giving people the feeling that they will not panic. When encountering mixed traffic and congested road sections, vehicles can pass slowly by themselves, and the avoidance angle and planned route are reasonable.

Huawei's "Shuangzhi" empowers to test drive the brand-new Lantu Dreamer Gankun Edition.

  Using navigation to plan the route, when encountering a road section without lane lines, the vehicle can keep driving in the middle of the road, and the obstacle identification in front is also more accurate. Avoiding and bypassing are no different from ordinary drivers. However, in places where road participants are more complicated, this intelligent driving system is almost the same as a skilled driver’s unprotected left-right turn, and the thinking and rhythm of the game are quite accurate, so there will be no great anxiety and shaking when sitting in the car.

  The most intuitive experience is that this is a set of NCA intelligent driving navigation AIDS that can be used all over the country without relying on high-precision maps, and can be opened at any time when you want to open it. Moreover, because the system includes intelligent driving scenes on open roads such as urban NCA and expressway NCA, and has intelligent parking functions such as AVP parking service assistance, APA automatic parking, RPA remote parking and VPD, the two systems seamlessly link all driving scenes, achieving its ability to support intelligent driving from parking space to parking space, saying that it is actually a smart driving ceiling at the same level.

  The adjustment interface of air conditioning is also integrated in the central control screen. Our test drive car is equipped with three-zone automatic air conditioning, and the rear row can also independently control the microclimate of air conditioning. The function is naturally full, with an intelligent air management system and a car-mounted fragrance system that supports adjustable fragrance.

  Space has always been a strength.

  The driver’s seat is spacious and comfortable, with a strong sense of business in shape, and the filling material inside is soft. The addition of wings mainly enhances the wrapping rather than the sense of movement. The headrest has a butterfly-shaped shape, which has a good sense of support on the shoulders, and the overall support and wrapping are in place. It can be seen that the shape has been determined after studying quite a few human samples. The surface of the whole seat is concave and convex, and the leather surface is perforated to further highlight the sense of luxury. In configuration, the main driver’s seat is also equipped with 12-way electric adjustment and the main driver’s headrest sound. The two seats in the front row support 10-point massage function, which is very comprehensive.

  The overhead entertainment screen is naturally not absent. This 17.3-inch screen is also a popular configuration of electric MPV at present. It can also realize the functions of mobile terminal access, wireless screen projection, etc. The UI interface of the entertainment screen is also quite different from that of the front central control, which can bring more comfortable ride and entertainment experience to the rear passengers without learning cost.

  Dreamer Gankun’s version of the two-row seat control area is on the armrest, where there is a 6-inch control screen and a 2.5D glass arc design. You can control the seats, media, heating and cooling boxes, sunshade and so on through this touch screen. Although the functions are conventional, the atmosphere, sense of technology and sense of ceremony are full.

Huawei's "Shuangzhi" empowers to test drive the brand-new Lantu Dreamer Gankun Edition.

  The popular "big piece" of MPV is the refrigerator, but the Dreamer’s Gankun version is also very top-notch in this part. The temperature of the 13-liter heating and cooling box in the central armrest area is -6~15℃ in cooling mode, and the heating mode is 30-50℃, which is not a problem. In addition, it also has an additional front door, which can make the main and auxiliary drivers more convenient to use.

  Each of its seats strives to be treated indiscriminately, and the spatial performance of the third row is more in line with its volume. After the second row of seats is adjusted to the default position, the space obtained by the experiencer can be described as spacious, and the sense of riding is directly higher than that of the second row of a general compact SUV. Functionally, there is even a slide rail, with 4-way electric adjustment of backrest angle and seat front and rear, and all three seats are equipped with heating.

  Dreamer Gankun version of the ceiling is made of suede material with delicate feel, which has a strong sense of high quality. The top of the passenger compartment is equipped with an oversized two-stage panoramic skylight with electric sunshade, which further enhances the sense of space opening.

  In terms of storage space, there are many small details such as specially designed storage space with limit and hooks inside the carriage, but the volume is average, but passengers sitting in any position are completely enough.

  The opening of the trunk of the new car is relatively low from the ground, and the suspension can lower the body, making it easier to carry heavy objects. The whole space of the trunk is not large, but it is completely enough for daily use. It is worth mentioning that the third row of seats can be folded and laid down in 46 pieces, which can hold larger items, and moving is not a problem.

  Besides being tough and economical, how comfortable is it?

Huawei's "Shuangzhi" empowers to test drive the brand-new Lantu Dreamer Gankun Edition.

  In terms of power endurance, the brand-new Lantu Dreamer is equipped with the self-developed Lanhai power system, which is available in pure electric and plug-in versions. The whole system comes standard with intelligent electric four-wheel drive, and the maximum power of the system is 420 kW. The PHEV version is equipped with a 1.5T engine and a 41.7 kWh battery. The CLTC has a pure battery life of 235km and a comprehensive battery life of 1411km, with excellent energy consumption performance. Although the zero-hundred acceleration is of little significance in this car, its score of 5.9s is enough to cope with many scenes.

  We test-drive the PHEV version. The super-large battery and motor power limit make it a pure tram during the test drive. Although it has super horsepower, it is an MPV that takes a comfortable route. When you drive it, you feel that it gives you enough affinity. In normal driving, its output characteristics are no different from those of many pure electric vehicles. No matter the throttle, brakes or even steering wheel feel, it is completely unnecessary to re-adapt. Engineers’ ability to adjust cars with high horsepower and heavy weight can be easily perceived.

  The front and rear double motors are quite brisk. When the car is suddenly accelerated, it will still rush forward with its head held high. For most people and passengers, the power is very surplus, but the body movements are pragmatic and there is no dizziness when sitting in the car. But many times, its power seems to be more inclined to let you enjoy the linear output of stepping on the accelerator pedal. The sports mode is not so manic, and the economic mode is not so stingy, but the understanding of your needs is always just right.

  There is no need to worry about the connection of power systems between pure fuel and electricity. The intelligent SOC strategy will carry out intelligent self-deployment of fuel and electricity energy, and switch different working conditions through the millisecond-level response energy conversion system, so that the energy reserve and application are excellent. When in normal use, just don’t worry about it.

  When the kinetic energy recovery intensity is set in the weak mode, the drag force of the system is difficult to be detected, and the drag force of the power system in the "strong" mode still cannot reach the single pedal logic you imagined. However, even if the car is heavy, the calibration of the brake pedal is still remarkable. When you step on the pedal, the braking force given in the initial stage is slightly soft, but it can always stop completely at the position you need.

  On the chassis, the front double wishbone+rear five-bar independent suspension structure, equipped with intelligent four-wheel drive system and air suspension with magic carpet function +CDC, or all-aluminum chassis, this is the top hardware equipment. Its style is obviously inherited from the old models, and its support is tougher. In the face of small and medium bumps on the road, it can take it very calmly. Most of the short and fine vibrations caused by road breaks and gravel can be well filtered out, but it will not give you a clearer sense of the road. In the face of large ups and downs such as the sunken manhole cover with high deceleration zone, it can quickly pull the swaying body posture, which is calm and has a strong sense of advanced. The chassis texture brought by CDC with pre-scanning and air suspension is really incomparable to many cars using traditional chassis architecture.

Huawei's "Shuangzhi" empowers to test drive the brand-new Lantu Dreamer Gankun Edition.

  As for the control, the steering has a strong electronic smell, but it has a relatively uniform and appropriate damping feeling. Because of the volume, when driving on narrow roads, you can feel the feeling of a big car at the rear of it, but its turning radius is not large, and it will not be too hard to turn around in the face of some narrow roads.

  Summary:At the beginning of this year, Lantu officially announced a strategic cooperation with Huawei. The debut of the brand-new Lantu Dreamer’s flagship four-wheel drive Gankun version is so logical. Its launch enriches the product matrix of Dreamer series, and also takes advantage of Huawei’s advantages in intelligence. Based on the industry’s top intelligence and wisdom, it will be the ceiling model of Lantu Dreamer in the future.

  Therefore, on the Dreamer’s Gankun edition, we can naturally see the ceiling-level products piled up. After all the long boards are stretched, Huawei’s "double wisdom" will empower them, and the brand influence of Lantu will also usher in a new refresh.

Four brothers of the blind: filial piety is the happiest thing.

    







 Although life is a little hard, the four blind brothers and my mother are very happy.


    Because there is an old mother who needs more care, the four blind brothers chose to be strong, and letting my mother enjoy her old age became their support and belief in hard life. As a result, the four blind brothers spent more than 20 years in their 7-mu responsibility field, learned all kinds of farming, and even built three big tile houses by thrift and borrowing money. With optimistic and open-minded mind and the belief of honoring my mother, their dark lives have warmth and light.


     ■ Playback of deeds


    In Chenwan Village, Shengfo Town, Yanshan County, Cangzhou City, there is such an extraordinary family: the eldest Chen Yanqi, 53 years old, the second Chen Yanqi, 50 years old, the third Chen Yandong, 46 years old, the fourth Chen Yanhui, 43 years old, and the four brothers live with the 82-year-old mother Ma Xiufen. The four brothers are all simple and honest, but their eyes are cloudy. They have been suffering from strange eye diseases since childhood, and their eyesight is getting worse and worse. They were completely blind at the age of 20, and after diagnosis, they are rare retinal nerve atrophy in the world.


    Twenty years ago, the father who supported the whole family died. There were five people in the family, and only the old mother had a pair of healthy eyes. How can such a family live? In the face of the great test of life, the four brothers did not shrink back. Facing Lacrimosa’s mother every day, they firmly said: "We don’t rely on anyone, we work on our own land, and we will give you a pension!"

  Is "artificial meat" edible? Is online celebrity food reliable? Are probiotics really useful? What foods have you paid attention to in the past 2019? What troubles have they brought you? Food safety concerns people’s health and life safety. At the "Media Communication Meeting on Scientific Interpretation of Food Safety and Health Hotspots in 2019", which was directed by China Association for Science and Technology and hosted by chinese institute of food science and technology recently, experts combed and interpreted the hot events of food safety that the public paid attention to in the past year, and made suggestions for food safety supervision by popularizing food safety knowledge through examples. This edition extracts some hot topics to interpret.

"artificial meat"

Scientific and technological problems to be solved, standards and regulations to be improved.

  Interpretation expert: Wang Shouwei (Director of China Meat Food Comprehensive Research Center and Dean of Beijing Food Science Research Institute)

  "Artificial meat" is synonymous with foods that are not naturally produced and have a similar taste to meat. It is usually divided into two categories: vegetable protein meat and cell cultured meat. The emergence of "artificial meat" on the one hand is to meet the rapidly growing meat demand of consumers, on the other hand, it provides a way to effectively reduce the land occupation of animal husbandry, the use of water resources and greenhouse gas emissions, and solve the problems of environmental protection and sustainable development.

  In recent years, the processing technology of vegetable protein meat is becoming more and more mature at home and abroad, and many enterprises have developed vegetable protein meat products with vegetable protein as raw materials. The research on using animal stem cells to produce cells to cultivate meat has also made great progress, and many enterprises have announced that they can develop cells to cultivate meat in the laboratory. Vegetable protein meat has great market potential and a high degree of commercialization. In the future, developing products more similar to real meat has become a direction for the food industry and scientific and technological circles.

  In the innovation and development of "artificial meat", it is necessary to increase scientific and technological input and solve the existing scientific and technological problems of "artificial meat". For example, research on the formation mechanism, raw material supply and processing technology of vegetable protein meat should be carried out to build a new research and development system. In the process of industrialization, we pay attention to improving the flavor, texture and nutrition of products, and constantly meet the increasingly diversified needs of consumers. Carry out research on the basic theory and key production technology of cell-cultured meat, and establish a production technology system of cell-cultured meat suitable for human food manufacturing.

  While innovating and developing, adhering to product quality and safety is the foundation of the development of "artificial meat". It is suggested that the new ingredients and new production technology added in the production of "artificial meat" should be systematically evaluated for safety, and an independent standard system and an objective supervision system should be formed in the evaluation of product safety and nutritional components, so as to promote the benign development of the industry.

  Scientific and rigorous standards are the cornerstone of the healthy development of the industry. In China, the development momentum of vegetable protein meat industry has been formed, and the product categories are relatively mature, but the existing laws and regulations are not suitable for product innovation and industry development; The development of its standard should be carried out as soon as possible, and the definition, classification method and production technology should be clearly defined, which will provide convenience for government supervision and provide reference for the direction of production and innovation of products in the industry. In addition, the research and development of cell-cultured meat in China is still in its infancy, but the development speed is very fast, and the research on standards and supervision methods has just begun; The division of supervisory responsibilities and division of labor system should be clarified, and a strict system of standards and laws should be formed. In addition, public science popularization should be carried out to guide consumers to correctly understand and rationally consume "artificial meat".

Online celebrity food

Strictly guard against the transformation of "red and black"

  Interpretation expert: Ma Guansheng (Head of the Department of Nutrition and Food Hygiene, Peking University College of Public Health)

  Some sellers make use of social media’s special publicity and marketing methods to dress up homemade food as "online celebrity" food, which is popular in the circle of friends. From home-made delicious food to home-brewed fruit wine, from morning tea snacks to midnight snacks, from beauty soup to dietary remedies, there are all kinds of foods in the circle. Online food attracts waves of consumers with its novel appearance, photos or taste. However, when consumers buy food, they often ignore the quality of the food itself, including raw materials, production date, shelf life and production address.

  Due to the special sales channels (such as WeChat circle of friends, micro-stores), online celebrity food has some problems, such as difficult management and lack of effective supervision mechanism. Taking the incident of "there is no milk in milk tea" in online celebrity as an example, China’s national standard "Tea Beverage" (GB/T 21733-2008) defines milk tea drinks and milk tea-flavored drinks as liquid drinks prepared by taking water extract of tea or its concentrated solution and tea powder as raw materials and adding one or more of milk or dairy products, sugar and/or sweeteners, edible milk flavor essence, etc. Although there is a requirement for the protein content of milk tea in this standard (≥ 0.5%), but milk or dairy products are still only one of a variety of optional ingredients, not a hard requirement. Therefore, due to the lack of clear standards for existing milk tea, there is an embarrassing situation that "milk tea does not contain milk", which increases the maneuverability of merchants and brings blind spots to food safety supervision.

  It is suggested to improve the supervision mechanism and clarify the responsibilities and supervision methods of all parties in the business activities of non-traditional foods such as online food sales. At the same time, strengthen regular sampling and random inspection, and urge network platforms and production operators to implement the main responsibility. Strike hard at illegal food safety behaviors in online sales, strictly investigate and deal with behaviors such as "brushing the bill" and "false comments", and protect consumers’ rights and safety with strict supervision.

  Online celebrity food is mainly sold through the online platform, so the online platform should assume the responsibility of screening and supervision. The network platform should establish a mechanism to help the superior and limit the inferior, strictly control the entry threshold of merchants, inspect and regularly review their retail qualifications and relevant licenses for selling products, and prevent counterfeit and shoddy foods from being sold on the network platform. Food enterprises and individual food producers should strengthen the construction of industrial chain safety, ensure the safety and traceability of product sources, make the product chain clear, and prevent and control risks. As consumers themselves, they should constantly improve their health literacy and food safety literacy, make rational purchases, and not blindly "chase after the red".

probiotics

The efficacy has the specificity of strains and people.

  Interpretation expert: Chen Wei (Academician of China Academy of Engineering, Chairman of Probiotics Branch of chinese institute of food science and technology, Vice President of Jiangnan University); He Guoqing (Vice Chairman of chinese institute of food science and technology Probiotics Branch, Professor of Zhejiang University)

  Probiotics have a strict definition: they must be living microorganisms, which are beneficial to the health of the host when ingested in sufficient quantities. Moreover, the health function of probiotics should be based on scientific and rigorous clinical trial evaluation and evidence-based medical evidence. At present, tens of thousands of published academic papers have studied the functions of different probiotic strains, confirming that the core function of probiotics is to improve the health of human gastrointestinal tract. In addition, in vitro experiments such as cell model, animal experiments and human experiments show that probiotics may have potential beneficial functions to improve metabolism and nervous system. However, in vitro experiments and the actual human digestive system are completely different worlds, and the results of in vitro experiments can never be used to claim the functions of probiotics. Animal experiments can be used as a reference, but it needs to be confirmed by large-scale and deeper human or clinical experiments.

  It is a long-term, rigorous and scientific process for human beings to explore the efficacy of probiotics. At present, there are various probiotic products with claimed functions on the market. However, it should be emphasized that the academic community has reached a consensus that the core function of probiotics is to improve gastrointestinal health.

  Generally speaking, the mainstream probiotic strains in the market are all isolated from healthy people and fermented foods with a long history of safe use. Most of them are considered as non-pathogenic symbiotic microorganisms, and their safety has been recognized by authoritative organizations. Of course, for sick individuals, such as patients with severe infection or immunodeficiency, they should be used with caution or consult a doctor.

  It should also be noted that the efficacy of probiotics has the specificity of strains and people. There are differences in probiotic efficacy among different strains; There are also differences in physiological regulation of probiotics among different hosts. Therefore, in the future, we should confirm the relevant probiotic functions at the strain level, judge and apply the individual functions of probiotics according to the individual characteristics of different hosts, and pay attention to personalized precise nutrition. Of course, the industrial application of probiotics must also be verified by scientific and rigorous processes. For example, the species, even the genetic composition and basic physiological and biochemical characteristics of the strain are first studied, and then the adaptability, safety and probiotic characteristics of the strain are evaluated in turn, and finally the probiotic dosage and probiotic combination with satisfactory efficacy are selected.

  In addition, consumers should choose probiotic-related products scientifically and reasonably. For lactic acid bacteria drinks, consumers should pay attention to distinguish product types when purchasing. According to the relevant standards in China, the labels of lactic acid bacteria drinks should be marked with live bacteria (non-sterilization) or non-live bacteria (sterilization), and they can be distinguished by labels when purchasing. When consumers buy yogurt, they should keep it reasonably according to the label. Low-temperature yogurt should be sold in cold storage. When they return home after purchase, they should put it in the refrigerator as soon as possible and drink it in time to ensure its strain activity.

  Probiotics have individual differences in their effects on health, and there is no "all-purpose" probiotic strain, which is suitable for everyone and all physical conditions. We should further strengthen the popular science education of consumers, popularize the professional knowledge of probiotics and clarify the scientific concept of "quantity" of probiotics, so that consumers can rationally choose probiotic products.

Self-heating food

It is necessary to cross the safety hurdle of "self-heating package"

  Interpretation expert: Lu Fuping (Vice President of chinese institute of food science and technology and Vice President of Tianjin University of Science and Technology)

  Self-heating food is a product that heats food with flameless self-heater and quickly reheates it to edible state. In recent years, a series of self-heating products represented by self-heating hot pot have developed rapidly. Besides the common self-heating hot pot and self-heating rice, there are also self-heating porridge, noodles, rice noodles, soup, etc., which are diverse and meet the urgent needs of consumers for hot food in more consumption scenarios.

  Although the safety of self-heating food is generally controllable, the safety risk of "self-heating package" should be paid full attention to. Since self-heating food uses the chemical reaction between heating agent and water to generate heat to heat the food. Occasional phenomena such as "self-heated food rupture" or "unstable temperature of self-heated food" have aroused people’s concern about the safety of self-heated food.

  Under the current self-heating technology in China, the chemical self-heating package used for self-heating food is mostly magnesium/iron for military use and aluminum-water for civilian use. No matter what kind of heating package, a small amount of hydrogen will be produced when heating. If individuals eat or a small number of people gather to eat, even in a closed environment, the amount of hydrogen generated by the heating of the heating package is far from the limit that can cause explosion. Under normal circumstances, the normal products will be eaten according to the normal operating procedures, and there will be no risk and safety problems such as cracking. However, if people eat a lot of self-heating food at the same time in a closed environment, or if the vent hole on the self-heating food packaging box is blocked, there may be potential safety hazards, which need to be paid full attention to.

  It is suggested to increase the research on the safety of self-heating package and develop a self-heating package with high efficiency and good safety. By developing energy-efficient formula and new heating device, the generation of hydrogen and water vapor can be controlled or reduced, the demand for energy efficiency release and utilization can be improved, and the safety level can be improved. Develop a new type of physical self-heating device, use renewable energy and reduce pollution. In addition, it is necessary to enhance the effectiveness and support ability of the self-heating device in various scenarios.

  The rapid development of self-heating food industry has attracted a large number of enterprises to join. However, due to the imperfect standards and specifications of self-heating food, the enterprises that have joined the self-heating food industry are mixed, which seriously affects the healthy development of the industry. At present, only the group standard "Self-heating Convenient Cuisine Products" issued by China Business Federation in 2017. From the perspective of regulating the industry, self-heating food needs more stringent standards to ensure its healthy development. It is understood that the industry is actively exploring how to establish a unified standard, for example, by standardizing the chemical composition and proportion, heating intensity, hydrogen production and other indicators contained in self-heating food heating packages, and making clear requirements for the treatment of final waste, so as to improve the entry threshold of the industry and standardize the healthy development of the industry.

Special medical food

Not for everyone

  Interpretation expert: Ren Fazheng (Academician of China Academy of Engineering, Vice Chairman of chinese institute of food science and technology Probiotics Branch, Professor of China Agricultural University)

  Special medical food is formula food for special medical use, which is specially processed and prepared to meet the special needs of people with limited eating, digestive and absorption disorders, metabolic disorders or specific disease States for nutrients or meals. It also has a very strict classification, which is currently divided into two categories: people aged from 0 months to 12 months and people over 1 year old.

  On the basic functions of special medical food — — At present, there is a broad consensus on nutritional support, including improving the treatment and rehabilitation effect, shortening the course of disease, reducing medical expenses, increasing the turnover rate of hospital beds, and reducing the readmission rate, which can be solved through nutritional support and special medical food. The World Health Organization has proposed that if more money is invested in nutrition and health care, less 8.5 yuan can be spent on treatment and the cost of rescue in 100 yuan can be saved. It can be said that the nutritional support function of special medical food is indispensable in clinic. Of course, it can’t replace drugs.

  Special medical food is a new industry in our country, and our government attaches great importance to it, and has made very strict management regulations at the beginning of the industry development. Special medical food should be registered by the food safety supervision and administration department of the State Council, and the formula of special medical food should be based on the research results of medicine and nutrition, and its safety and clinical application effect need to be scientifically confirmed.

  According to news reports, some illegal enterprises produce ordinary solid drinks, pass off as special medical milk powder and mislead consumers. This kind of behavior belongs to false propaganda, which should be severely cracked down and strengthened management. In addition, when the special medical food is registered and put on record, the product formula and production technology are strictly regulated. Food enterprises should produce special medical food according to the registered formula, and cannot produce special medical food without obtaining the registered formula and production license.

  The demand emphasizes that special medical food is special and not suitable for everyone. Moreover, different special people need different special medical foods. We should strengthen the popularization of special medical food, let consumers know its particularity and eat it according to the doctor’s advice.

Reduce salt, oil and sugar

Science and technology lead, scientific implementation

  Interpretation expert: Chen Junshi (Academician of China Academy of Engineering, General Consultant of National Food Safety Risk Assessment Center)

  The diet of Chinese residents is high in salt, oil and sugar. "Three reductions" is not an isolated matter, it is an important part of the whole reasonable diet. Whether it is the government supervision department, food industry or consumers, it is necessary to raise awareness and establish the concept of "reasonable diet".

  Carrying out the "three reductions" action is not a matter for any department or enterprise, but should be coordinated and promoted by all parties. The government should formulate corresponding policies to lead the "three reductions" action, and catering and food processing enterprises should provide diversified products with different levels of salt, oil and sugar for consumers to choose by reducing the use of salt, oil and sugar. Residents gradually reduce the use of salt, oil and sugar in their daily cooking.

  In particular, the food industry and catering industry should accelerate the transformation and upgrading of nutrition according to the health needs of consumers, and take the initiative to take measures to reduce the use of salt, oil and sugar in food. This requires increasing scientific and technological support, laying a solid scientific foundation, solving the problems such as product flavor change and shortened shelf life that may be caused by "three reductions", innovating and developing new foods, and leading a healthy transformation with science and technology. In addition, there are different dietary nutrition problems in different regions and different groups of people, so nutrition science education should be targeted and reflect differentiation. Nutrition intervention should be precise, and the implementation of policies should be based on science and practical. Focus on guiding enterprises to provide more differentiated products for consumers to choose, and guide consumers to choose products that suit them reasonably.

  The action of "three reductions" needs to be carried out step by step in line with China’s national conditions, instead of "eating a fat man at one breath". It takes time to change people’s tastes, not quick. The improvement of cooking, methods and food processing technology also takes time, which cannot be achieved overnight, and should be carried out step by step in accordance with scientific laws. The transformation of consumer health concept needs long-term positive guidance and popularization of scientific knowledge. Therefore, the implementation of the "three reductions" action must be gradual, and various problems must be solved step by step.

Food fraud

Counterfeiting detection technology needs to be upgraded

  Interpretation expert: Wu Yongning (Chairman of chinese institute of food science and technology Food Authenticity and Traceability Branch, Technical Chief of National Food Safety Risk Assessment Center); Chen Ying (Vice President and Chief Engineer of China Academy of Inspection and Quarantine)

  Food quality, food safety and food truth are three attributes of food. The authenticity problems such as food fraud and forgery exist at home and abroad. For example, as the saying goes in China, "selling dog meat by hanging sheep’s head" and the "horse meat passing off as beef" that happened in Europe a few years ago. The World Health Organization once pointed out that apart from food-borne diseases, more and more food fraud and food fraud problems need to be paid attention to.

  Ensuring the authenticity of food is not only to protect public health, but also a necessary measure to curb the market chaos of "bad money drives out good money", standardize the market competition order and boost food consumption confidence. At present, China has basically met the public’s requirements for the quantity and quality of food, and the concern for food safety has reached a higher level. However, for a long time, the investment in food authenticity technology is relatively lacking, and it is difficult to guarantee the scientific supervision of "food authenticity". If food fraud is "a magic height of one foot", then the detection technology of counterfeit identification must be "a magic height of one foot".

  It is suggested to increase the scientific and technological investment in food authenticity research and overcome the technical difficulties and supervision problems of food authenticity. At the same time, speed up the transformation of technical standards of food authenticity, formulate corresponding detection methods and standards, and provide technical support for scientific supervision of food authenticity in China.

EE Architecture | Central Computing+Regional Control Architecture Information of Domestic Mainstream OEMs

The development of intelligent cockpit, intelligent driving and intelligent network will promote the continuous increase of new functions. At the same time, the demand for high computing power and large bandwidth data transmission will become more and more urgent, coupled with the concept of "software-defined car", which will jointly promote the upgrading and transformation of the whole vehicle EE architecture; At present, various car companies have gradually started to move from the distributed architecture with independent functions to the domain control architecture with integrated functions, and will eventually move to the centralized architecture with central computing and regional control.

One,Tesla’s "quasi-centralized architecture" leads the trend.

1. Distributed architecture VS centralized architecture

1) Under the distributed architecture, software and hardware are closely coupled, and OEM is more dependent on suppliers. In the process of cooperation, only one technical standard (such as communication information -XX signal, communication form -CAN/LIN, etc.) is provided to Tier1, and each system is provided by different suppliers, resulting in OEM’s vehicle software becoming a mixture of many independent and incompatible software systems. If the OEM wants to change or add new functions, it needs to talk with different suppliers, so it is obviously constrained by suppliers.

Secondly, with more and more ECU, the wiring harness in the car will become longer and longer, which not only increases the weight and cost of the car, but also brings great trouble to the layout and assembly of the car. Moreover, the computing power of each ECU can not be coordinated, resulting in a great waste of computing power.

2) Under the central computing+regional architecture, the computing power is gradually concentrated in the center. First, multiple ecus are merged into a domain controller, and then the domain controllers will continue to merge, eventually forming the ultimate layout of a central computing platform +N regional controllers. At this time, the number of ECU will be greatly reduced, which not only reduces the application cost of ECU and the wiring cost between controllers, but also contributes to the lightweight design of the whole vehicle.

Secondly, the sensors and actuators are connected to the nearby regional controllers, which can better realize the expansion of hardware. At the same time, the structure of the regional controller is easier to manage, and it is easy to realize the automatic assembly of the wiring harness.

2. What is Tesla’s "quasi-centralized architecture"?

In 2019, Tesla has realized the EE architecture scheme of central computing+regional controller on Model3, leading the trend. So what are the advantages of Tesla’s architecture?

The vehicle electronic and electrical architecture of Tesla Model3 is divided into four parts: CCM (Central Computing Module), BCM FH (Front Body Control Module), BCM LH (Left Body Control Module) and BCM RH (Right Body Control Module). CCM (Central Computing Module) consists of three modules: infotainment system (IVI), driver assistance system (ADAS) and communication system inside and outside the vehicle.

1)Front body control module:Responsible for the power distribution of the whole vehicle and the logical control and drive of the electrical appliances in the front compartment of the vehicle;

2)Left Body Control Module:Responsible for the power distribution, logical control and drive of the left-hand electrical appliances, including the convenience control of the left body and chassis control such as steering and braking;

3) Right body control module:Responsible for the power distribution of right-hand electrical appliances, the logical control and drive of right-hand and back electrical appliances, including the convenience control of right body, power system, air conditioning, etc.

Advantages of Tesla EE architecture:

1) The hardware part of the intelligent driving module adopts a self-developed FSD chip; For the software part, the operating system is customized based on open source Linux, and the middleware is developed by itself. The software and hardware are self-controllable, which not only helps to speed up the iterative update of vehicle functions, but also greatly reduces the development cost of the whole vehicle.

2) On the software architecture level, SOA architecture is adopted to facilitate the deployment of SOTA and the collection and analysis of cloud data.

There is no doubt that Tesla’s electronic and electrical architecture is advanced. Its central computing module -CCM integrates intelligent driving module, audio-visual entertainment module and in-vehicle networking module, and shares a liquid cooling system. Basically, the prototype of centralized architecture is realized, but it is not a centralized architecture in the strict sense. The industry calls this type "quasi-centralized architecture".

Therefore, even Tesla is still a long way from a truly centralized architecture. Considering the technical maturity and cost at that time:

1) The communication architecture is still relatively traditional, mainly based on CAN bus, and the control is still distributed on MCU, and the basic software of MCU adopts FreeRTOS.

2) The central computing module CCM is separated: only the MCU of audio-visual entertainment, the FSD of intelligent driving and the networking module inside and outside the vehicle are formally integrated on one board, but each module still runs its own operating system independently and completes its own tasks independently.

Even so, Tesla is still a practitioner of the most advanced concept of central computing+regional control architecture, which has triggered the learning and catching up of other peers in the industry.

Second, the "chaser" of the domestic Tesla EE architecture

In the era of intelligent and software-defined cars, whoever can master the dominance of EE architecture and software will occupy the commanding heights of the smart car market. Therefore, domestic mainstream vehicle companies are also actively carrying out relevant layout, and the mass production models of "quasi-centralized" architecture scheme will be launched around 2022-2023.

edit

However, the centralized architecture of OEM planning is not too unified in form. For example, the vehicle computing platform of SAIC Zero Beam adopts two HPC high-performance computing units; The scheme of GAC or Great Wall adopts three major computing platforms: central computing platform, intelligent driving domain and intelligent cockpit domain. But generally speaking, the R&D design concept is similar: the hardware adopts the architecture scheme of central computing+regional control, and the software adopts the design concept of SOA software architecture.

1. SAIC Zero Beam-Galaxy Full Stack 3.0 Scheme

Hardware platform:It consists of two HPC high-performance computing units, HPC1 and HPC2, and four ZONE controllers. Two high-performance computing units are used as the computing center of the whole vehicle to realize the functions of intelligent cockpit, intelligent driving and redundant backup of intelligent driving; Four area controllers are used to realize the related functions of different areas.

Galaxy Full Stack 3.0 Hardware Platform (Source: SAIC Zero Beam Presentation Materials)

Remarks:

1) In August, 2021, SAIC Zero Beam and Xinchi Technology reached a strategic cooperation, and based on the Zero Beam Galaxy Full Stack 3.0 architecture, they will jointly formulate the development roadmap of the chip and vehicle electronic and electrical architecture; At the same time, the two sides will jointly explore and jointly develop a narrow operating system suitable for full stack 3.0 around the chip-level underlying software operating system and virtualization platform technology;

2) In September, 2021, SAIC Zero Beam announced that it had jointly designed and developed the HPC based on "Zero Beam Galaxy Full Stack 3.0".

Software platform:Adopt SOA integrated software platform of cloud management.

1) The software platform is decoupled from the hardware chip and the operating system. Even if the chip types and operating systems of different EE architecture platforms are different, the software platform can still be translated and reused. For example, Zero Beam’s 1.0 architecture platform and 3.0 architecture platform still use the same software platform, although the underlying hardware and operating system are different.

2) In the application layer, through middleware and SOA atomic service layer, a unified and standard API interface can be provided upwards, which makes the application layer development easier and more reusable. At the same time, coupled with the software platform SDK, OEMs, suppliers, third-party developers and users can all join in the application development and realize the co-creation of application ecology.

2. Gac ean-Spirit architecture

1)Hardware platform:Spirit architecture consists of digital mirror cloud, three core modules and four regional controllers (left/right/front/back). Among them,The three core computer modules include central computing unit, intelligent driving domain control module and cockpit domain control module; The central computing unit covers the new energy control module and the body control module, and is responsible for controlling the functions of vehicle running, braking and vehicle equipment.

  • The CPU is equipped with NXP S32G399 gateway computing chip, which is composed of 8 A cores and 4 M cores, and has built-in LLCE+PFE acceleration engine, and the communication delay is ≤ 20μ s.;
  • Cockpit control module is equipped with Qualcomm 8155/8295 chip, 7nm process, 105K DMIPS computing power, and supports 3D character image rendering, face recognition, AR-HUD and other functions.;
  • The intelligent driving domain control module is equipped with Huawei Shengteng 610 high-performance chip and 7nm process, which supports the expansion of computing power of 200~400TOPS. The image processing capacity of ISP can reach 2.4GPix/s, which can cope with complex road conditions such as high speed and cities.

2) Software platform:SOA software architecture with layered design is adopted.

  • Basic intermediate layerAdopt atomic service encapsulation and standardized interface;
  • Dedicated intermediate layerAdopt enhanced combination service, which can be executed independently;
  • APP software layerIs an independent component decoupled from the bottom layer and can directly call the service.

The software architecture realizes service, atomization and standardization of components, decoupling of software and hardware, improving the ability and speed of OTA, and realizing plug and play of hardware-adding new application modules can realize new scenarios.

3. Great Wall Motor-GEEP4.0 architecture

1) Hardware platform:GEEP4.0 architecture consists of central computing platform (CCU), intelligent cockpit module (HUT), intelligent driving module (ICU), and three regional controllers (VIU_L, VIU_R and VIU_F).

Central computing unit CCUThe main responsibility of CCU is to deal with the functions of auxiliary autopilot, power, chassis, car body, air conditioning, car body status and mode management in a centralized way. Under the high-order autopilot configuration, CCU can be used as a backup of L3 domain controller to achieve the lowest risk conditions.

3 regional controllers:Is a standardized control unit.,Divide, deploy and develop according to the body domain, and arrange them on the left, right and front respectively, which is responsible for integrating some MCU around, that is, integrating ECU, power supply, controller and input/output. At present, most of the software algorithms of the three VIUs have been moved to CCU and developed by Great Wall Software Team. VIU only keeps a small part of logic, and it is more responsible for driving I/O.

4. Tucki X-EEA3.0

In November 2021, Xpeng Motors released the Tucki G9 at the Guangzhou Auto Show, which is scheduled to be listed in 2022; The car adopts Tucki’s brand-new X-EEA 3.0 architecture. At present, the official customs of Tucki has not revealed too many specific technical details. The author has compiled the following information for your reference:

  • Hardware architecture:Central supercomputing+regional control;
  • The software platform architecture is divided into three layers.System software platform, basic software platform and intelligent application platform;
  • Communication architecture:Adopt gigabit Ethernet communication;
  • Data schema:Realize non-inductive OTA- The domain controllers all control the memory in partition isolation, one area is used for upgrading and the other area is used for normal operation of vehicles; Therefore, even when the vehicle is driving normally, OTA upgrade of new functions can still be carried out at the same time;
  • Power architecture:The power supply of electrical equipment is controllable, and intelligent and accurate power distribution is carried out according to user scenarios, which reduces unnecessary power waste and optimizes the use of electricity.

Third, the impact of the upgrade of EE architecture

1. Reshaping the supply chain system

Under the traditional distributed architecture, the software is highly coupled with ECU. OEM has a strong dependence on Tier1, which is dominant, and the software and hardware are directly supplied to OEM by packaging. The industrial chain is relatively simple, with software product suppliers/chip suppliers (Tier2) in the upstream, component integrators (Tier1) in the midstream, and vehicle integration plants (OEMs) in the downstream.

With the upgrading and transformation of electronic and electrical architecture, the hardware is gradually standardized, the software is separated from the hardware, and the software and hardware are decoupled, making it a reality to define the automobile by software. Therefore, OEM’s ability to master software-defined cars has become more intense, and they hope to gradually regain the long-awaited "dominance" from Tier1.

To this end, enterprising OEMs began to set up software teams to improve their software research and development capabilities, but there is still a long way to go. In this context, some people have seen the strong demand of car companies for the "self-developed and controllable" cooperation mode, so a new species-Tier 1.5 has emerged, which can support the customization of OEM products upwards and integrate and integrate Tier2 resources downwards, in order to get a share of this "dominance" battle.

At the same time, in order to maintain its dominant position, the traditional Tier1 has also started to vertically integrate and build the R&D capability of the whole stack of software and hardware, transforming from a component supplier to a system solution provider, that is, upgrading from Tier1 to Tier0.5-it can not only provide OEM with software and hardware integrated products, but also provide full-process services from pre-technical research and development to post-data sharing, hoping to maintain a "close" relationship with OEM.

2. Changes in the industry competition pattern

At present, enterprises engaged in research and development of advanced EE architecture can be roughly divided into three categories: vehicle enterprises, Tier1 and technology companies. Vehicle companies have a strong motivation to master the core technology and component dominance of centralized EE architecture, because they have already seen the benefits that this dominance brings to Tesla. However, in the short term, there are still a few vehicle companies that can realize all the self-research of these technologies and components. Most vehicle manufacturers will still rely on Tier1, technology companies and other suppliers to complete it together.

The development project of the vehicle electronic and electrical architecture is complex and the technical link is long. Only the players in the industrial chain can cooperate with each other in each link, give full play to their respective advantages, and form a joint force to achieve the effect that 1+1 is greater than 2. Only in this way can we help the whole vehicle enterprises to complete the upgrading of the architecture more quickly.

For OEM, we will choose the cooperation mode that suits us according to our actual situation:

1) For head car companies with strong R&D capabilities, such as Tesla, they will choose self-research in key core areas such as chip, operating system, middleware and domain controller system integration, while outsourcing some hardware production.

Secondly, the automatic driving perception algorithm is relatively complicated. Even some head car companies will choose to jointly develop the perception algorithm with software companies with strong strength in the industry. In this process, most of them will also learn from teachers, gradually improve their perceptual algorithm ability, and finally move closer to the goal of self-research in the whole stack.

2) For car companies with relatively weak software research and development capabilities, it is necessary to distinguish what is common and what is individual. Considering its own research and development strength and cost pressure, the common part can only be strategically abandoned and handed over to the right supplier to help it complete the development; For the part of personality, you need to do your best to differentiate and create your own brand power. For example, a domain controller or a central computing platform needs Tier1 or a software company with full-stack R&D capability to help it gradually open in layers, and then do personalized and differentiated development at the application layer.

At present, the demand of the main engine factory is personalized and diversified, and most of them tend to ask suppliers for customized development according to their own needs. At the same time, OEM is also trying to improve its own software development ability; In the long run, for Tier1 and the technology companies that intend to do Tier1, it is a general trend that the development rights of some software functions of domain controllers or central computing platforms are "taken back" by OEMs. Therefore, Tier1 and technology companies are also striving to build full-stack technology research and development capabilities for software and hardware to avoid becoming "hardware foundries" for OEMs.

3. The new opportunities brought by the upward breakthrough of EE architecture

In the critical period when intelligent driving entered the second half of the competition, OEM began to upgrade its electronic and electrical architecture to cope with the development of automobile intelligence and networking. In this critical time window, whoever can help OEM to take the lead in realizing the rapid replacement and iterative upgrade of hardware modularity, as well as the portability and maximum reuse of software modules, will win the favor of the OEM and gain a foothold in the new market.

The so-called times make heroes, so which types are more likely to appear "heroes" on the "new outlet"? The author judges that there will be the following types:

1) Dali AI Chip Company-the electronic and electrical architecture is developing rapidly towards domain centralization and central domain control. For OEMs, the choice of high-performance Dali computing platform is a top priority. Therefore, the suppliers of large computing chips will usher in a growing market space. In particular, some chip companies that have recently grown up in China-open system solutions, ability to understand localized scenes, and good engineering supporting services are their current advantages.

2) Domain Controller Integrator-With the upgrading of the electronic and electrical architecture of the whole vehicle, the penetration rate of domain controllers has been promoted, and the emerging market of domain controllers will have great growth space in the future. Domain controller integrators with reliable product quality, which can also greatly save costs and shorten the development cycle for OEMs, will usher in an opportunity for development.

3) Supplier of basic software platform-For the OEM with weak software power, there is no need to re-develop the common part of the basic software platform, because it will not be perceived by consumers. Therefore, you can choose to give this part to the appropriate basic software platform supplier, which can not only reduce your development difficulty and cost, but also use your own manpower and financial resources for the key personalized development part; It is conducive to shortening the product development cycle and bringing it to market as soon as possible.

4. What are the challenges to realize the central computing+regional control architecture?

1. The bottom "chip" foundation determines the height of the upper "architecture"

High-order autonomous driving requires more and more computing power. Carrying chips with more advanced process and stronger performance has become the primary problem to be considered in architecture design, because the mass production time of the planned chips will affect the landing time of the architecture scheme.

When designing the central computing+regional architecture, the central computing platform needs to meet the needs and characteristics of all domains at the same time. Therefore, it needs more powerful chips and a combination of various operating systems. The biggest challenge is to select the available chips. However, at present, there are no mass-produced chips that can meet the requirements of several functional domains at the same time, so most OEMs still adopt the scheme of piecing together multiple chips:

1) Vehicle control system: Generally, MCU is adopted, which runs mature Classic AUTOSAR basic software, which requires high real-time performance and safety level, but its computing power and storage are limited.

2) Intelligent cockpit and intelligent driving field need high-performance and powerful SoC chips, and also need to run complex operating systems, supplemented by middleware.

Secondly, there are more and more players in the field of in-vehicle with high computing power and high performance chips, and the iteration speed of chips is getting faster and faster. If the whole technical architecture needs to be reconstructed every time the chips are replaced, it will seriously affect the development speed of new products. Therefore, the central computing platform needs to have good expansibility, not only a unified sensor and peripheral interface, but also good chip compatibility.

2. Software Capability and Software Team Building

Software capability At present, the mainstream functional domain architecture can be divided into five domains: body domain, chassis domain, power domain, intelligent cockpit domain and autopilot domain. In the process of developing to a centralized architecture, cross-domain integration is inevitable, such as integrating the body domain, chassis domain and power domain into a vehicle control domain, and the ultimate goal in the future is to integrate all functional domains into a central brain. In this development process, not only need to build a large number of software function service capabilities; At the same time, powerful software capabilities are needed to cope with the system collaboration among the underlying real-time operating system, AUTOSAR and other key software modules.

Another embodiment of software capability is that OTA, especially FOTA, requires OEM to have strong software development capability and be able to develop the control software of the underlying executive parts, so as to truly realize the function or performance of software-defined cars.

In 2018, the American Consumer Report magazine pointed out that Model3 had serious problems in emergency braking at high speed. When Model3 is driving at 60 mph, its braking distance is about 46.3 meters, which is higher than other models in the same class. To solve this problem, Model 3 upgrades the firmware by pushing it remotely. The end result is that the emergency braking distance of Model3 is shortened by about 6.1 meters through OTA.

The hardware of the Model 3 braking system is Bosch’s iBooster, but the electric control software at the bottom is developed by Tesla, so the characteristics of the brake pedal can be adjusted through OTA upgrade, that is, the braking force can be optimally distributed during the whole braking process by adjusting the braking response curve, thus shortening the braking distance.

Software team building- If OEM wants to realize the real software-defined car, that is, most functions and performances of the car are defined by itself, then its own research and development ability, especially the software research and development ability, will be a big test. Now powerful OEMs are setting up software R&D teams on a large scale, and software developers are obviously in short supply in the talent market. Even if you are willing to "seduce" with high salary and options, it is difficult to "set" the right talents. At the same time, the management and coordination of software teams are also complicated, which is where traditional OEMs need to carry out intensive learning again.

3. The problem of organizational system

Traditional OEM has a R&D team, a product system and a supply chain system that have been gradually built and improved for many years. However, there will be more things to consider and worry about when the whole vehicle EE architecture changes, such as the reusability of the original production line, the compatibility of the architecture with the huge product line, and the supply chain problems around the world.

A major feature of the centralized architecture is that the computing power is concentrated in the center. In this case, many ecus will definitely be cut off. If a large number of ECU’s are cut off in the car, it is a matter of life and death for employees who rely on these parts and related suppliers. If they can’t make internal and external adjustments, it will be difficult for the new architecture to be promoted and implemented quickly.

To some extent, the traditional OEM has become a "double-edged sword" by virtue of the advantages of supply chain and product system accumulated over the years, and it has begun to hinder them from carrying out architectural innovation. Therefore, it is impossible for them to "cut across the board" when carrying out the structural reform, completely demolish the previous scheme and switch to the new E/E architecture. They can only use the existing resources to make a gradual transition and evolution, and gradually improve their own software R&D capabilities and change their R&D organizational structure to adapt to the new R&D process.

The new forces that build cars have no concerns in this regard, and they can start from scratch. Although it doesn’t accumulate as many past resources as traditional OEM, and it doesn’t have the previous historical burden, it can make new attempts without scruple.

Therefore, from this point of view, the huge organizational system of traditional OEMs has really held them back.
