Explain in detail the chassis improvement of the new generation SAIC-GM New Excelle.

　　Excelle, which went public in 2003 and has entered the fifth sales period, lacks a real replacement model. Although Shanghai GM claims that the new Excelle just listed is a "vertical replacement" model, it has been choked by many netizens that it is a change of soup. Aside from the changes in internal and external styling, where is the improvement of the new Excelle in the chassis?

"New Excelle"


　　Although Shanghai GM claims that the new Excelle just listed is a "vertical replacement" model, it has been choked by many netizens that it is a change of soup. Where is the improvement of the new Excelle chassis?


● It is not a multi-link, and the rear suspension of the new Excelle has not changed.


　　Calling the rear suspension structure of Excelle a multi-link structure has become a "popular" misunderstanding since it was just listed, and even many sales representatives pointed to two obvious links in the rear suspension of Excelle, which made many consumers "seeing is believing". On the occasion of the listing of the new Excelle, the theory of "multi-link rear suspension" once again surfaced. In fact, the rear suspension structure of Buick Excelle has not changed as a mid-term modified model, and the rear suspension of Excelle is not the legendary multi-link rear suspension.

"It is a misunderstanding that the rear suspension structure of Excelle is called multi-link structure since it was just listed."


　　Excelle’s rear suspension structure should be a two-link strut independent suspension, which belongs to a variant of McPherson independent suspension used for rear suspension. It is very similar to McPherson’s independent suspension structure, and the shock absorber is also used as the pillar. However, the A-shaped lower arm with left-right steering motion function in McPherson suspension is replaced by two tie rods hinged with bolts. Because the steering function is not needed in the rear suspension, engineers have strengthened the connection stiffness by limiting the degree of freedom.



"Many sales representatives pointed to two obvious connecting rods in the rear suspension of Excelle, which made many consumers" seeing is believing ""


　　However, these two tie rods, which replace the A-type lower arm, are interpreted by many sales representatives as the so-called "connecting rods" in multi-link suspension. In fact, these two tie rods can only be said to be seemingly connecting rods, but they are not really connecting rod structures. In curve performance, the stability and support stiffness of connecting rod strut suspension are not very satisfactory. Therefore, the two-link strut independent suspension still has obvious handling performance gap compared with the real four-link independent suspension.


● Where is the improvement of the new Excelle chassis?


　　Consumers who have driven the old Excelle will be deeply impressed by the emergency sideline of Excelle and the dynamic performance of the body that tilts and shakes when entering the corner. This time, in the chassis improvement of the new Excelle, Shanghai GM has made improvements for the large roll angle and soft suspension setting of the old Excelle.



"Shanghai GM has made chassis improvement for the old Excelle with large roll angle and soft suspension setting."


　　By increasing the stiffness of front and rear springs by 40%, increasing the damping of front and rear shock absorbers by 26% and 43% respectively, and increasing the diameter of the front and rear ends of the stabilizer bar, the new Excelle has improved the suspension setting and favored the tough design preferred by China consumers. Because the spiral springs and shock absorbers are more rigid, the steering body roll is reduced, the steering sensitivity is increased, and the vehicle handling is enhanced. Of course, you can’t have your cake and eat it. When the road is bumpy, the more rigid suspension system equipped by the new Excelle will be difficult to filter and absorb the vibration well, and the comfort will be affected.


● The suspension structure of the new generation Excelle in 2009 will be greatly changed.


　　The rear suspension form of the new Excelle still maintains the two-link strut independent suspension. This suspension structure was very popular in the 1980s, because although it has a performance gap with multi-links, it also has good characteristics: the moving parts of the suspension are simple, the structure is light, and the movement stroke of the suspension is large, which can achieve good comfort. However, with the development of suspension technology, the two-link strut independent suspension has gradually fallen out of favor. Many compact cars pursuing handling performance orientation have adopted more advanced four-link rear suspension structure, while compact cars or small cars pursuing balanced orientation have turned to more cost-effective and compact torsion beam trailing arm rear suspension.



"GM will use the torsion beam to drag the arm rear suspension in the new generation of Excelle models launched in 2009."


　　At present, Tianjin, Tianjin and other older models still use two-link strut rear independent suspension. However, from Tianyu, the follow-up model of Antelope, and the rear suspension structure of New Elantra, the follow-up model of Elantra, have turned to the torsion beam to drag the arm rear suspension, which shows the general trend. And GM will also use the torsion beam to drag the arm rear suspension in the new generation of Excelle models launched in 2009.


● Summary: New Excelle has some adjustments.


　　Seeing this, I believe that you have some understanding of the chassis improvement of the new Excelle.
　
　　From the suspension structure form, the new Excelle belongs to the change of soup without changing medicine, so it is hard to say that it is a real "vertical replacement". However, as a mid-term modified model, the change of the new Excelle is still satisfactory, which has adjusted many problems such as soft suspension and large roll. The medicine was not changed, but the proportion of ingredients was adjusted. It remains to be seen whether Shanghai GM can be recognized by consumers. (Text/Li Yi)

　　Brand-new Zhiji LS6, the benchmark of technological innovation.

　　The brand-new Zhiji LS6 released this time vividly presents the accumulated achievements of SAIC’s long-term technological innovation. The brand-new Zhiji LS6 is equipped with the "digital chassis of the lizard", with a million-level driving quality, which is easy to drive and the whole family is scrambling to drive.

　　As the first SUV of its class with "digital chassis" and "four-wheel steering", the brand-new Zhiji LS6 has a driving texture comparable to that of a million-class benchmark. The fastest acceleration is 3.48 seconds, the braking distance is only 33.76 meters, and the elk test score is 82.7km/h, reaching the top level in the industry. Its driving stability is also comparable to one million.The vehicle model, when passing through the speed bump in the residential area or the potholes in the urban area, has less bumps and softer body feeling. In terms of comfort and safety, the brand-new Zhiji LS6 has completely surpassed the million-dollar benchmark, and can provide users with a safe and comfortable VIP experience on all kinds of roads. For example, when the high-speed overhead turns into a big bend, the Yuntai body keeps the body from swinging, which obviously eliminates the carsickness of the rear passengers; When braking at an intersection, comfortable braking can make the brakes nod, which is as smooth as the footwork of the national guest driver. What’s even more subversive is that the turning radius of the brand-new Zhiji LS6, which is close to 5 meters long, has both a good driving of the car and a good installation of the SUV, so that users can choose the car without entanglement. Moreover, thanks to the "full-architecture OTA" capability, "Linglizard Digital Chassis" has continuously realized the OTA with new functions of the chassis, so as to be "not outdated for five years and not anxious about buying a car".

　　It is particularly worth mentioning that the "Linglizard Digital Chassis" empowers the rear-drive SUV with the powerful ability comparable to that of the traditional four-wheel drive. Not only is the city’s travel power super strong, the driving is super stable, and the energy consumption is super low, but it also adds light off-road capability, reducing vehicle deviation by 80% in extreme weather of heavy rain and heavy snow; The city can be wild, which perfectly adapts to the diverse and colorful life scenes of users.

Interpretation of ＂Auto Insurance real-name registration system＂： Whoever buys auto insurance will pay, and others may not advance.

　　Changsha Evening News August 7th (all-media reporter Liu Qiongping correspondent Ye Zhou) Following the implementation of real-name payment and SMS authentication for motor vehicle insurance policyholders in Henan, Jiangsu, Hainan and Xinjiang, Hunan will also join this camp. The reporter learned from Hunan Insurance Industry Association today that from August 10th, Hunan car owners will also be the beneficiaries of the new policy of "auto insurance in real-name registration system".

　　Interpretation of "Real-name Authentication of Auto Insurance Payment"

　　According to the introduction of Hunan Insurance Industry Association, the real-name authentication of auto insurance policyholders means that when purchasing auto insurance, the insurance company must carry out real-name authentication on the payment account and check it with the information of the policyholders to ensure that the information of the payment account is consistent with that of the policyholders, that is, "whoever buys auto insurance pays, ensuring that the payer = the policyholders".

　　According to reports, the insured must use his real-name account to pay the insurance premium in full at one time, and other third-party institutions and individual agents such as insurance companies, insurance professional intermediaries and part-time agencies are not allowed to advance the auto insurance premium in any form.

　　In order to ensure the implementation of the policy, Hunan Province will also implement a mobile phone number SMS verification system, that is, when the insured or the insured is an individual and the insured vehicle is a family car, it must be verified by mobile phone SMS through the national auto insurance information platform, and the insurance company can pay the bill only after the "verification code" feedback from consumers is entered.

　　For example, Zhang San insured his own car or someone else’s (non-company’s) car, and the nature of vehicle use is family car (non-business nature), so he must carry out real-name payment authentication and SMS verification at the same time. In the SMS verification link, Zhang San must provide the verification code to the cashier of the insurance company before the next insurance process can be carried out.

　　In the face of the upcoming new auto insurance policy, some car owners may feel that "procedures have become troublesome."

　　"In fact, buying insurance does increase the procedures for real-name authentication, but it is definitely beneficial for most car owners." The relevant person in charge of the Hunan Insurance Industry Association said that auto insurance real-name registration system will make consumers clearly understand the amount of premiums paid — — The amount paid is all the expenses of the insurance policy, which fundamentally eliminates the "catty" of private delivery and unauthorized underwriting in the auto insurance industry; Secondly, after the real-name payment, the insurance company can remind the owner in time when renewing the insurance in the coming year.

　　Four steps for beginners to pay for auto insurance on the road.

　　The first step is to choose an intentional insurance company to insure. Insurance methods include calling the insurance company’s customer service phone, logging in to the insurance company’s official website, logging in to the insurance company’s mobile phone client and going to the insurance company’s service outlets.

　　Step 2, SMS verification. If the applicant or the insured is a natural person, it must actively verify the mobile phone number under the name of the applicant through the national auto insurance information platform, and check the rationality and repeatability of the mobile phone number. After receiving the SMS verification code, consumers must inform the insurance company staff of the "verification code" to help complete SMS verification. It is worth noting that the total number of different policyholders and insured persons corresponding to the same mobile phone number cannot exceed 3, and more than 3 people will not be able to obtain the verification code.

　　The third step is the real-name authentication of payment. After the SMS is verified, it will enter the real-name authentication of payment, and the consumer will sign the customer authorization letter (electronic version or paper version) issued by the insurance company to confirm. After the insurance company is authorized, it will check the consumer’s information to ensure that the premium payment account is consistent with the insured’s information.

　　The fourth step is to pay the bill. After passing the real-name payment authentication, consumers can use their real-name account’s bank card, Alipay, WeChat or cash payment to pay the premium in full at one time. When the payment account is consistent with the information of the insured, the payment is successful and the policy can be printed. When the two are inconsistent, the payment will fail and the bill will not be issued.

　　What should I do in these situations after the New Deal?

　　Hunan Insurance Industry Association reminds consumers to pay attention to the following matters after the implementation of real-name registration system for auto insurance payment.

　　First, what payment methods can I choose? When insuring a private car, you can pay the premium through bank card, Alipay and WeChat payment, and make sure to use your account. Other payment methods without real-name authentication cannot be used. For special circumstances such as cash payment by the insured, inconsistency between the insured’s information and the payment account information, it is necessary to consult the insurance company first or go through the insurance formalities in the business premises of the insurance company. The insurance company will record and video the underwriting process and keep audio, video, pictures and other materials.

　　Second, how many cars can an applicant buy insurance for at most? If the owner of the vehicle is an individual, when the applicant agrees with the owner, the same applicant can vote for up to 50 vehicles. If the applicant does not agree with the owner, the applicant is only allowed to insure up to 3 vehicles for compulsory insurance and commercial insurance.

　　Third, will it affect the auto insurance premium? The real-name authentication of auto insurance payment only involves the change of premium payment method. The premium price of auto insurance purchased by consumers has nothing to do with the payment method, and will not increase because of it. The amount of premium is related to factors such as vehicle model, insurance type, number of accidents and years without accidents.

　　Fourth, what is the difference between the insurance procedures and the past? First of all, when consumers apply for insurance, they must fill in the SMS verification code received by the customer’s reserved mobile phone number for verification. Secondly, the insurance company must obtain the authorization of consumers to verify the payment account. Finally, when paying premiums, consumers should carry out real-name authentication of the payment account.

Maotai Liquor in the Republic of China： ＂Lai Mao＂ and its trademark designer

In February, 2021, "Hu Wensui Art Museum" was inaugurated in the Ancient City Park in Huangpu District. It used to be the former site of Hunan Qianye Office. Today, this white-walled gray tile building with Huizhou style meets the public with a new look. Hu Wensui is a famous calligrapher in contemporary China and a representative of Shanghai style calligraphy. More than 100 calligraphy and paintings of Mr. Hu Wensui at various stages are displayed in the museum. Two years ago, on behalf of her family, Mrs. Hu Wensui donated nearly 1,000 pieces of Hu Wensui’s works to the Huangpu District People’s Government. Now, with the completion of the Art Museum, Shanghai Huangpu has added a cultural business card.

Hu Wensui Art Museum Inauguration Ceremony

Hu Wensui was born in 1918. He studied calligraphy with Mr. Shen Yinmo in the early 1950s. Prior to this, he also had two experiences in the military and business respectively. Compared with calligraphy attainments, the world knows little about another legendary experience of Hu Wensui: designing a trademark for "Lai Mao" wine.

First, Hu Wensui’s career in the home front

When the Anti-Japanese War broke out in 1937, Hu Wensui was less than 20 years old. He joined the propaganda team of the Political Propaganda Department of the 105th Division of the National Revolutionary Army. The 105th Division was adapted from Zhang Xueliang’s guard during the "Xi ‘an Incident". Wang Tiehan, the division commander, once refused to carry out the "non-resistance" order during the "September 18th Incident" and fired the first anti-Japanese shot in Northeast China. The 105th Division went all the way to the west, and successively participated in Changsha Battle and Nanchang Battle. Hu Wensui also went to the mainland to engage in propaganda work with the army.

In 1941, China entered the most difficult stage of the Anti-Japanese War. The territory in the southeast fell, and the rear area suffered an unprecedented military blockade. Yunnan-Guizhou became the only channel for the Allies to transport goods to China. This year, Hu Wensui went to Lashuo, Myanmar with the army, worked as a mechanic in the transportation department and participated in the construction of the Yunnan-Myanmar Highway. Later, due to illness, Hu Wensui left the army and temporarily stayed in Guiyang. After his military career came to an end, Hu Wensui began to consider the way of industry. Because he is good at calligraphy and painting, he first opened a small shop in Guiyang to undertake trademark advertising and printing business, and later opened a small printing factory. During his years in Guiyang, Hu Wensui made friends with people from Guizhou’s industrial and commercial circles for support.

Mr. Hu Wensui (1918-1999)

At this time, Lai Yongchu has become an influential leader in Guizhou’s industrial and commercial circles. Lai Yongchu is a native of Guiyang. His family started with groceries trade and loans in the early years, and gradually grew from "twenty taels of silver" to tens of thousands of wealthy businessmen. Lai Yongchu, the son of Lai’s parents, took charge of the bank business after inheriting the family business. In 1936, Lai Yongchu founded Daxing Industrial Company to expand its business scope. After having more money, Lai Yongchu started his business activities in Guiyang and joined the social circle of Guizhou Chamber of Commerce. Around 1940, Lai Yongchu entered the Guiyang Chamber of Commerce and served as the executive director. With the help of the organizational strength of the Chamber of Commerce, he successively founded Guizhou Business Daily and Guiyang Business Friends Club to serve local businessmen. During the Anti-Japanese War, Lai Yongchu also served as a senator in Guiyang and a bank manager in Guiyang.

Mr. Lai Yongchu (1902-1981)

In 1937, due to poor management, the former Hengchang Burning House in Maotai Town, the shopkeeper Zhou Bingheng took a stake in Daxing Industrial Company in Lai Yongchu with the winery. In 1941, Zhou Bingheng resold the winery to Lai Yongchu. After Lai Yongchu took over, he renamed it "Hengxing Winery" and introduced a new product: Laimao.

Brewing was originally the tip of the iceberg in Lai Yongchu’s business empire, but later it became the most famous brand. The acquaintance and cooperation between Hu Wensui and Lai Yongchu also started from "Lai Mao".

After Lai Yongchu named the product "Lai Mao", he began to organize the design of trademarks. Almost at the same time, Hu Wensui and Lai Yongchu met. Therefore, the design of "Lai Mao" trademark was undertaken by Hu Wensui. The trademark of "Lai Mao" is a Dapeng bird pattern, and it symbolizes the world with a ring as the background. The Roman pinyin "Lay Mau" of "Lai Mao" is printed on the top of the Trade Mark, and the English logo "Trademark" (meaning registered trademark) is printed on the bottom. In 1943, Hu Wensui established a firm foothold in Guiyang and opened the "Shilun Printing Factory". Since then, the trademarks of "Lai Mao" wine have been printed by Shilun Printing Factory.

"Lai Mao" Bottle Trademark in the Republic of China

The trademark design of "Laimao" wine has incorporated many modern business ideas. Previously, most of the trademarks of Maojiu were not fastidious enough. For example, when Huajia Chengyi Shaofang Maojiu applied for a trademark in 1940, it was only marked with the words sorghum spike and "Huisha Maojiu". After the product name and trademark of "Lai Mao" came out, various wineries followed suit. Later, Chengyi Shaofang also called its maojiu "Huamao", and the Ronghe Shaofang of the Wang family also called itself "wangmao". Many imitation Mao wines outside Maotai Town also use this title, and imitation Mao wines such as "Jinmao", "Dingmao" and "Yuemao" emerge one after another in the market.

The story about the falsification of Moutai is not only in today’s market. Let’s take a look at Lai Yongchu’s own memories:

"In the old society, everyone just made money, and there was no credibility at all. It was really impossible to stop counterfeiting. Not only is it popular in Guiyang to sell fake maojiu, but even on the way from Guiyang to neighboring provinces, hotels sell fake maojiu, some print trademarks as fake maojiu, and some dry-recycle empty maojiu bottles, one in a corner, and then put sorghum wine as maojiu, which makes a lot of profits. "

"Lai Mao" wine advertisement and "Yue Mao" wine advertisement imitating Lai Mao trademark in the Republic of China

Second, the cooperation between Hu and Lai and the rise of Maotai liquor

Modern Moutai generally originated in the late Qing Dynasty and was first managed by salt merchants. At the end of the 19th century, the brewing workshops in Maotai Town included the "Chengyi Burning House" of the Fahrenheit family and the "Ronghe Burning House" of the Wang family. In the 1920s, Zhou Bingheng, a businessman from Guiyang, opened the Hengchang Burning House in Maotai Town, and since then, there have been three wineries in Maotai Town. In the 1940s, Lai Yongchu acquired Hengchang Shaofang and renamed it Hengxing Winery. Hengxing Winery is the youngest of the three wineries in Maotai Town, but by the time of the victory of the Anti-Japanese War, it has become the largest winery. This is closely related to the luck, business opportunities and brand management in Lai Yongchu.

After the outbreak of the Anti-Japanese War, the National Government moved westward to Chongqing, and a large number of military officials moved inward. Hundreds of thousands of military and political personnel moved inward, which brought huge consumer demand. Maotai liquor was gradually welcomed by the upper class because of its high price and scarcity. Whether it’s the official reception of military and political high-level officials or the social gifts of writers and writers, Moutai appears in their daily lives, which is of course in sharp contrast with the poor life of middle and lower-level civil servants in the rear area.

Throughout the Republic of China, the price of Mao wine has been at a high level. Before the outbreak of the Anti-Japanese War, the price of a bottle of Mao wine was about 1 silver dollar, and it was necessary to add 1-2 cents to buy it from the agency. After the outbreak of the Anti-Japanese War, the Kuomintang-controlled areas began to experience serious inflation, and the price of Mao wine was also rising. According to the Shanghai newspaper in January, 1946, "Lai Mao" liquor was "sold for 5,000 French francs in Chongqing, and the counterfeit currency was one million yuan". By November 1946, a bottle of Mao wine would cost 25 thousand yuan.

After the war, Moutai also broke through the southwest corner and sold to the whole country. In 1946, Chongqing Credit Information News reported as follows: "Moutai produced in Renhuai, Guizhou Province, has a mellow taste and is well-known. Before the Anti-Japanese War, it was sold all over the country. Due to the war, the sales area was gradually reduced, only the rear area was used as the sales area, and the transportation convenience area was gradually restored. The oldest Moutai company, Cheng Yi Heng Xing Rong and the three companies, had an annual output of several hundred thousand Jin, and it was still being promoted in Guangzhou, Beijing and Shanghai due to their achievements.

After the victory of the Anti-Japanese War, Shilun Printing Factory and Hengxing Winery have already taken shape. Hu Wensui Shilun Printing Factory reached the scale of "more than 100 employees and two rubber offset presses", while there were only five printing equipments in Guiyang at that time. The printing factory undertakes the printing business of teaching materials, literature, history and scientific research books. Hu Wensui, 30, has become a rising star in Guiyang’s cultural and business circles. In 1950, facing the new situation, Hu Wensui made a choice. He took the initiative to hand over the printing factory to the Guizhou provincial government, and the Shilun Printing Factory was merged into Guizhou People’s Printing Company, and later changed to Guizhou Xinhua Printing Factory, and embarked on the track of state-owned. Hu Wensui moved his family to Shanghai and began his calligraphy life.

Lai Yongchu’s career in Guiyang has also further grown. He once served as the general manager of Guizhou Provincial Bank, mastering the financial lifeline of Guizhou, and concurrently engaged in salt industry, mining industry, newspaper industry, charity and education. Looking back at the history of Lai Yongchu’s commercial prosperity, the rapid growth of its wealth and even its social status is almost synchronous with the growth of Guizhou’s wartime economic status. By entering the Chamber of Commerce, Lai Yongchu began to frequently deal with high-ranking military and political figures in Guizhou, and presented them with "Lai Mao" wine as a gift. After the Kuomintang retreated to Taiwan Province, Guizhou was not liberated. Because of Lai Yongchu’s position in the financial world, Gu Zhenglun, then chairman of Guizhou Province, persuaded Lai Yongchu to go to Taiwan Province and asked him to ship all the funds of Guizhou Bank to Taiwan Province, and left a plane waiting in Xingren. In the end, Lai Yongchu chose to stay in Guizhou to welcome the new regime.

From a larger historical background, the story of Hu Wensui’s participation in Lai Mao’s trademark design outlines the social mobility of China when he went to war. Before the Anti-Japanese War, Guizhou was located in the border and the traffic was blocked. In wartime, the National Government used the central finance to develop southwest transportation, and Guizhou became a transportation hub in the rear area. In addition, the inward migration of personnel has also brought a large number of talents to the southwest. The cooperation between Lai Yongchu and Hu Wensui is the embodiment of this social mobility.

Third, the "Lai Mao" international movement under the background of marketization

It can be said that the popularity of Moutai in the Republic of China, especially in the rear area of the Anti-Japanese War, laid the foundation for becoming a national famous wine in one fell swoop after 1949. In 1950, Lai Yongchu went to Beijing with the "Kunzhu delegation" from Yunnan-Guizhou New Liberated Area, and was invited to attend the first anniversary ceremony of the National Day. With Lai Yongchu, 50 bottles of "Lai Mao" wine were sent to Huairentang Auditorium in Zhongnanhai for exhibition.

In November 1951, Renhuai County Monopoly Bureau came forward to redeem Fahrenheit Chengyi burning house, and immediately established "Guizhou Province Monopoly Company Renhuai Maotai Distillery". In October 1952, the "Ronghe Burning House" of the Wang family was confiscated and included in Maotai Distillery. In February 1953, Hengxing Distillery in Lai Yongchu was taken over by Maotai Distillery. Soon, Maotai Distillery was systematically supported by the central government and the Guizhou provincial government, and changed into an enterprise directly under the Guizhou Provincial Department of Industry. Its production, domestic sales and export links were repeatedly concerned by central leaders such as Zhou Enlai and Zhu De.

After 1950s, China Liquor went through the industrialization stage in the planned era. At the same time, the development of famous wines has become a task with financial significance. Before 1978, Maotai Distillery successively obtained construction funds from the central and provincial levels, as did other famous wineries. After 1980s, the liquor industry gradually entered the stage of marketization, private liquor factories began to rise, and liquor pricing power was decentralized. The descendants of Lai family in Guiyang have developed various kinds of liquor named after Lai Mao, which was once very popular. In 1988, Maotai Distillery registered the "Lai Mao" trademark, but the registration was revoked because Maotai Distillery did not use the "Lai Mao" trademark for three years. Since then, the competition for trademark rights around "Lai Mao" has also begun. For a time, thousands of "Lai Mao" wines emerged in the market, and the trademark of "Lai Mao" was used at will until Maotai Distillery regained the trademark of "Lai Mao" in 2014.

The international movement of "Lai Mao" brand under the background of marketization is behind the commercial operation of thousands of small wineries. There are two important conditions for this operation: technology sharing in the planned era and the redevelopment of historical assets.

In the era of planned economy, the local industrial departments were responsible for liquor production. In order to realize the innovation of national brewing technology, the central government promoted the technical circulation of liquor by administrative means. For example, in order to expand the output of Moutai, the Ministry of Light Industry has spent a lot of resources to study the production of Moutai in different places, and set up a "Moutai ex situ test plant" in Zunyi. Another example is that the Ministry of Light Industry has systematically summarized the production technology of Fenjiu, LU ZHOU LAO JIAO CO.,LTD and other famous wines, and extended its technology to all county-level wineries in China, thus forming a series of local brands, which have become important original capital of private wineries in the wave of marketization.

This mechanism is also applicable to the economic ecology of Maotai Town. From the three burning houses in the Republic of China to the monopoly of Maotai Distillery in the planned economy period, and then to the rise of thousands of brewing enterprises in Maotai Town after marketization, it is precisely the achievements of the popularization of brewing technology that have released the so-called "Maotai-flavor liquor" and thus formed a huge industrial scale. Under the huge profit space, "Lai Mao" has become a sales gimmick for private capital to enter the market.

All kinds of "Lai Mao" wine.

As an important historical asset attached to Moutai, "Lai Mao" brand is the key to enhance the product premium of newly established liquor enterprises. The attached history has thus become a common phenomenon in the liquor industry. With regard to the story of "Lai Mao" in the Republic of China, Hu Wensui’s experience in designing the trademark of "Lai Mao" was almost annihilated. On the contrary, fictional urban legends spread widely. For example, "Lai Mao won the gold medal in the 1915 Panama World Expo" was a typical oolong in commercial marketing.

In a word, the trademark story of "Lai Mao" not only outlines a "dark line" in the social and economic history of the rear area of the Anti-Japanese War, but also runs through the ups and downs of the development history of liquor in the 20th century.

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.

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.

2) Software platform

  • On the application software level, integrate big data, cloud diagnosis, information security and other software systems to achieve functional integration;
  • Deploy different domain software in different cores-MCU core adopts CP Autosar, and deploy different domain electronic control software in multiple MCU cores respectively; The HPC core adopts Linux OS and AP Autosar middleware;
  • By deploying software in different domains in different cores, the integration between multiple domains is opened horizontally, and the communication between the underlying hardware, operating system (CP autosar, Linux OS), middleware (AP autosar), protocol stack and application software is opened vertically.
  • Support FOTA, planning some comfort functions will support SOA.

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.
