　　[Aika car test drive original]

　　In the dead of winter, the ice lake in the northeast is always busy. Some people dig ice nets to catch fish, while others are busy "catching shrimp households" (drifting). In yakeshi at -30℃, the ice thickness has reached 120cm. In previous years, the lens drifting in a piece of white was always contracted by others. Now, we have also opened the right to enjoy the ice, bringing "China Xinggan Elite Driving School Ice and Snow Season". Can I graduate if I take part in the ice and snow test drive for the first time?

　　This time Geely assembled all the models of CMA architecture series — — (|) (Hi·X petrol-electric hybrid version with thunder spirit engine), (|) and (|) are China stars and all-stars.

　　There are three courses in elite driving school: elite, advanced and master. From basic skills to ultimate challenges, the difficulty is gradually increasing. The activity is located in Hulunbeier Winter Automobile Test Site of China Automobile Center, and readers who have read the articles on ice and snow test drive should be familiar with it.

　　Experience items: snow linear acceleration, snow linear braking, snow winding pile.

　　Model: Xingrui

　　Driving mode: front drive

　　Powertrain: 2.0T(140kW, 300Nm)+7DCT

　　Elite courses mainly cultivate "ice sense". For me, who is used to relying on static friction, it is the first step to lighten and soften the actions I do on asphalt pavement on weekdays. The test drive of Xingrui changed the snow tires, and the basic grip was improved. A series of operations such as acceleration and braking can be easily completed by properly controlling the rhythm.

　　When winding the pile, the ESC is on. I slow down the initial speed to 40-45km/h, and the steering range is half a turn as before. The front of Xingrui can easily keep up with my hand movements, and the rear of Xingrui obediently follows rather than catches up, which is stable and controllable.

　　Experience project: ice ring drift

　　Model: Xingyue S

　　Driving mode: front four-wheel drive

　　Powertrain: 2.0T(175kW, 350Nm)+8AT.

　　Advanced courses mainly teach drift skills. In order to stretch the grip, all test drive models are equipped with nail tires. The most basic project is ice ring drift. During the demonstration, the coach has been emphasizing the importance of "repair". After drifting, the vehicle can draw a circle by constantly repairing the direction and the throttle. Listening is one thing, but doing it is another. When I stepped on the accelerator deeply and entered the direction, I quickly fell into several novice misunderstandings.

　　If you drive too fast, you will spin in the same place; If you hit too much, you will rush out of the ice ring; If the adjustment is too slow, you will have no posture … … In short, the coordination of throttle and direction is the most important detail for ice novices to practice. Don’t fall into the self-doubt that "you think you have learned, but in fact you have failed to learn". Relax your mind and "cut" the ice ring into several sectors and barely draw a semicircle.

　　Xingyue S provides ESC OFF mode with little interference to drift. However, due to the large steering ratio of vehicles, novices often need to make large-angle corrections, which inevitably leads to some confusion. After several groups of practice, I actually feel like I just finished dancing Pamela.

　　Experience items: 8-square, high-speed U-bend.

　　Model: Xingyue L

　　Driving mode: front four-wheel drive

　　Powertrain: 2.0T(175kW, 350Nm)+8AT.

　　Xingyue L has no ESC OFF, only ESC motion mode. Fortunately, its handling is not much discounted, quantitative sliding is allowed, and when the intersection changes direction, the car body tends to be stable and will not form a large backlash.

　　"Scandinavian cornering" used in high-speed U-bend refers to the action of destroying the center of gravity by swinging the car body, and then realizing the floating by shifting the center of gravity. The specific operation steps are to slow down before entering the bend and turn the steering wheel in the opposite direction of entering the bend. When the front of the car faces the outside of the bend, turn the steering wheel to Apex immediately to shift the center of gravity of the car body, so that the rear of the car slides. The front wheels of four-wheel drive vehicles will have power output, so the counter-hitting action to maintain drift after drifting should not be too big.

ChatGPT was born, which triggered a global hot discussion and thinking. In just a few weeks, people both lamented the rapid development of artificial intelligence and were shocked by the great changes brought by new technologies to life and production, as if suddenly, computers really had self-awareness.

Artificial intelligence, as a substitute for human labor force, is only the tip of the iceberg. What kind of changes can be imagined when ChatGPT is applied to the automobile field? At present, technology has developed to pre-process the influence of each terrain and road condition on the car body, so as to adjust the suspension in advance to improve comfort, handling and safety, but most of them are limited to high-end models of luxury brands and have not been systematically popularized. However, with the release of BYD Yunqi Intelligent Body Control System on April 10th, this situation will be completely changed. From passive suspension to active suspension to intelligent body control, the awareness of body is awakening.

First, create the highest level of global body control system.　

BYD Yunqi System is the industry’s first exclusive intelligent body control system for new energy. The full name of Yunqi is Yunqi intelligent adaptive body control system, which is an intelligent body control system developed by BYD for five years and costing billions of dollars. Including Yunqi -C intelligent damping body control system, Yunqi -A intelligent air body control system, Yunqi -P intelligent hydraulic body control system and unlimited Yunqi -X control system.

Yunqi represents the highest level of the global body control system, which brings subversive improvement to new energy vehicles of BYD Auto’s brands, covering different use scenarios such as home, sports, administration and off-road, and creating an all-round and luxurious driving experience for users. When the new energy vehicle has no traditional engine and gearbox, the impact of chassis technology on the driving experience of the whole vehicle will be further amplified, so the brand of electric vehicle has higher and higher requirements for chassis and suspension. Independent research and development is costly and time-consuming, and it is usually unbearable for brands with poor product matrix, which leads most car companies to choose outsourcing chassis technology, which is easily affected by technical bottlenecks and soaring costs.

Second, from perception to decision-making to implementation, break the monopoly of foreign car companies in one fell swoop.

Electrification has brought about the transformation of the whole vehicle architecture, and the vehicle control has changed from mechanical control to electrical signal control, and the accuracy, efficiency and intelligence have been greatly improved. The body control system, which integrates software and hardware technologies such as perception, decision-making, control and interaction, can not only surpass the past, but also provide rich car scenes. This is the intelligent body control system of Yunqi, and the following three levels are the core of Yunqi technology.

Perception is the premise of cloud chariot.

The first key problem of Yunqi is road perception technology, which is the first step to realize intelligent body control. The preview system deeply integrates multiple road surface sensing elements such as monocular/binocular cameras and laser radar to identify road surface features and elevation curves within the range of 5-150m in front of the vehicle, and the recognition accuracy is as high as 3 mm, and the recognition accuracy is over 99% within 15m. It not only realizes the functions of road surface recognition and all-terrain monitoring, but also can quickly adjust and adapt with the suspension system.

Accurate decision-making is the key to Yunqi.

After mastering the core technologies such as software architecture, strategy formulation, algorithm design, etc., BYD’s self-developed Yunqi Intelligent Computing Center has multi-core and efficient processing capability, supports multi-signal interfaces, and can drive various actuators. Through cloud computing, it can process information such as road state, body posture and wheel load, and output the best control strategy in real time.

Take high-speed cornering as an example. Usually, the center of gravity of the vehicle will tilt to the inside of the corner, thus reducing the comfort and handling performance. Yunbi can automatically adjust the suspension located inside the corner, reduce the movement frequency by increasing damping, and achieve the purpose of hardening the suspension. From the completion of road preview, to intelligent decision-making and implementation, Yunqi Supercomputing Center has realized highly centralized integrated control.

Efficient execution is the guarantee of Yunqi.

For the implementation level of Yunqi, BYD independently developed and controlled the whole process through structural design, performance simulation, test methods and other aspects, and combined with the full-stack self-research of system software, it can achieve the perfect adaptation effect of suspension software and hardware. Yunqi intelligent adaptive body control system achieves millisecond response adjustment from the state identification of sensing parts, to the information processing decision of Yunqi Supercomputing Center, and then to the control execution of the whole vehicle.

In addition, users can also control the suspension height and damping mode through the voice control or manual adjustment interface at the APP end of the mobile phone and the Pad end of the vehicle, thus gaining more fun.

Third, "devolve" luxury and make "value" upward.

Next, we interpret Yunqi -C, Yunqi -A and Yunqi -P respectively to see what contribution they have made to chassis awareness.

Yunnian -C intelligent damping body control system-popularization of technology, entering the homes of ordinary people.

Yunqi -C is the first active suspension product in China to realize full-stack self-research in system design, calculation, modeling, simulation, matching and adjustment. The system architecture includes key components such as perception component, decision component and execution component. The suspension system of Yunqi -C can actively control the electronically controlled shock absorber according to the road condition information, and the damping can be adjusted steplessly, which mainly serves the comfort and sports modes.

When the vehicle passes through the bumpy road, the comfort control strategy of high frequency and small damping is adopted to make the chassis "soft", which can effectively buffer the road excitation input and quickly restrain the vertical movement of the car body. Under the condition of 60km/h continuous vibration road surface, Yunqi -C can help the whole vehicle achieve 96% vibration isolation rate, which greatly improves the comfort compared with the traditional suspension. The roll speed of 100km/h double lane can also be reduced by 39.7%.

Yunqi -C is mainly used to improve daily driving comfort and handling performance, such as body pitch, corner roll and steering angle at medium and high speed, etc. This is a popular version of product matrix. At present, more than 80,000 vehicles have been loaded on BYD Han EV, Tang and Tengshi D9, and the product experience has been well received by the market. Later, it was officially upgraded to Yunqi -C through OTA software.

Yunnian -A Intelligent Air Body Control System-Breaking the monopoly, luxury and comfort are no longer far away.　

Yunqi -A intelligent air body control system is the first suspension product in the world to realize full-stack self-research in system design and calculation, simulation selection, function and strategy development, software algorithm development and integration, matching and adjustment technology and key parts design. The system architecture includes sensing, decision-making, execution components, and key components such as adjustment part. Its biggest highlight lies in the high integration of three adaptive adjustments of suspension height, spring stiffness and damping hardness with the adaptive adjustment function of dynamic embracing seat, which is of pioneering significance in the industry.

The total lifting stroke of Yunqi -A can reach up to 150mm, which can restrain the acceleration of the car body and brake pitching by more than 25%, and provide two modes of manual and automatic adjustment. In addition, the suspension height is adjusted adaptively with the change of vehicle speed.

BYD also creatively integrated the self-adaptive adjustment function of the dynamic embracing seat into Yunnian-A. In order to suppress the inertia deviation caused by the roll of the vehicle when cornering at high speed, the dynamic embracing seat provides airbag support at the waist of the seat, so that the user can maintain a good driving posture and ensure the safety and comfort of high-speed driving. According to the news of the press conference, Yunnian -A will be the first to ride on Tengshi N7.

Yunnian -P intelligent hydraulic body control system-the world’s first new energy, providing a strong off-road gas field.

Yunqi -P is the world’s first new energy exclusive intelligent hydraulic body control system developed by BYD. It efficiently integrates three core subsystems, namely mechanical, hydraulic and electronic control. The system architecture includes sensing components, decision-making components and more complex execution components. It has the functions of one-button leveling, single-wheel lifting, four-wheel linkage, simultaneous adjustment of height, stiffness and damping. The working environment covers -40℃ to 85℃, with an altitude of 6000m, which is suitable for extreme and harsh environments such as high temperature, cold, high humidity and high corrosion.

The biggest difference between Yunqi -C and Yunqi -A is that Yunqi -P can stably bear the sprung load weighing up to 5 tons. It is an intelligent hydraulic body control system with the maximum load-bearing capacity for new energy passenger cars among the active suspension products released in the industry. In addition, Yunqi -P has a wide range of suspension height active adjustment and four-wheel linkage capabilities. The total adjustment stroke of the front suspension and the rear suspension is 200 mm. When facing off-road scenes such as bullet holes and cross shafts, all four wheels can touch the ground as much as possible to provide sufficient tire grip and balance. And when camping on uneven ground, the four-wheel suspension can be lifted independently to keep the car body level.

As BYD’s first million-class luxury car, I hope U8 will not only surpass the predecessors of traditional SUVs, but also bring the safety, comfort and intelligence of intelligent chassis, and also bring the luxurious and comfortable feeling of integrating technology, new energy and new platform, covering all kinds of car scenes such as transportation, off-road, leisure and business.

To sum up, three different intelligent car body control systems actually correspond to three different consumption and car use scenarios, and the significance of cost performance and popularization brought by Cloud -C; Yunqi -A Active Road Perception and Advanced Air Suspension: Yunqi -P’s cross-era off-road innovation makes users feel the significance of intelligent body awakening from different levels of high school, middle school and low school.

Fourth, the autonomy of production equipment to software and hardware is the core of cloud technology.

From the perspective of global automotive technology, in addition to Rolls-Royce, there are three intelligent body control systems familiar to domestic consumers, namely, the magic body control system applied by Mercedes-Benz in GLE, the magic carpet intelligent air suspension of BMW 7 Series and Audi A8L active suspension technology.

BYD’s cloud technology not only fills the last short board on the traditional chassis, but also combines the pre-control with the wire-controlled chassis, creating a new integrated technology of vertical integration and realizing the straight-line overtaking of traditional car companies and new forces.

The core components of Yunqi released by BYD this time, such as compressors, distribution valves, testing instruments and so on, are all developed and produced by BYD, and the product matrix is subdivided into Yunpan -C, Yunqi -A and Yunqi -P, which comprehensively covers all civilian use scenarios to correspond to different models and consumer demands respectively. This chess game can be said to make opponents dream of it.

Five, R&D investment broke 20 billion, BYD technology is king.

Although the active body control system is not new, the whole technology of Yunqi is self-developed by BYD, which not only gets rid of the dependence of domestic brands on parts suppliers, but also realizes the independence of core technologies, which is the most admirable place. Especially when this system is endowed with perception layer and decision-making layer, the "self-awakening" suspension will bring us unprecedented experience and fun.

In order to increase its core competitiveness, BYD has made great efforts in technical input and output in recent years. In 2022, the accumulated R&D investment was 20.223 billion yuan, up 90.31% year-on-year. By the end of 2022, BYD had applied for more than 39,000 patents and authorized more than 28,000 patents worldwide, with nearly 70,000 R&D personnel. Under the research and development and investment at any cost, the peak technologies such as blade battery, DM-i super hybrid, E platform 3.0, CTB battery body integration and "Easy Sifang" have been released one after another, and the emergence of Yunqi has enabled BYD to keep ahead in technology, and at the same time, it has provided consumers with the best choice, no longer subject to the serious premium of joint ventures or imported cars, and truly fulfilled the significance of technology changing their lives.

There are still two months to the end of the year, and the automobile market is surging. In order to occupy the automobile market, major automobile brands have come up with unique tricks. Among them, the unique marketing strategy of the new M7 in Wenjie has gained widespread attention in the market. It is understood that Huawei not only provided 30,000 yuan worth of rights and interests for the new M7, but also promised to delay the delivery of subsidies for 200 yuan/day, providing consumers with a car purchase experience of "having benefits on the top and being guaranteed on the bottom", creating a record ceiling of 70,000 units in 45 days.

Different from the strategy of focusing on "promotion" when new cars of other automobile brands go on the market, Huawei has taken a different approach to stand on the side of consumers, dig deep into consumers’ needs, and introduce rights and protection at the same time. Specifically, the big rights and interests of this new car include:

(Time: 10.8-10.31)

(1) enjoy 5,000 yuan to deduct 8,000 yuan, and reduce the final payment;

(2) a gift of 12,000 yuan worth of interior and exterior decoration matching gold;

③ Enjoy the matching rights worth 15,000 yuan (as described below);

Max smart driving edition users can deduct the optional ADS2.0 urban navigation NCA function by equal amount;

Plus rear-drive users can choose and install a technology enjoyment package worth 15,000 yuan in equal amount;

Users of all models can also choose a combination of rights and interests with a value of 15,000 yuan (21-inch wheels with a value of 10,000 yuan and one of the original aftermarket products).

In order to make consumers worry-free about buying a car, Huawei has also made a care plan for the new M7. According to this plan, new M7 users who have completed the big payment before November 30, 2023, the order status on AITO App starts from the date of "delivery plan confirmed" to the date of "vehicle has arrived at the store". If the waiting period in the table below is exceeded, they will receive the cash subsidy for car pick-up care according to the number of days (vehicle arrival date-delivery plan confirmed date-waiting period). The standard of overdue subsidy is 200 yuan/day, up to 10,000 yuan.

On the basis of marketing strategy innovation, Yu Chengdong, managing director of Huawei, CEO of BG, and chairman of BU, a smart car solution, personally promised that Celeste Smart Factory is working overtime to ensure market supply demand. At the same time, the investment in the supply chain has exceeded 1 billion yuan, and new production shifts are running around the clock 22 hours a day, making every effort to ensure delivery. This wave of operations makes consumers satisfied with Huawei’s strength and commitment.

The new M7 in Wenjie broke through the large quota of 50,000 orders in 25 days, reaching 60,000 orders a month, and the quota has exceeded 70,000 units in 45 days! Such achievements are remarkable. Of course, the new M7 has achieved such good results, not only relying on welfare and rights, but also relying on Huawei’s strong product strength and user orientation.

Empowered by Huawei, the new M7 intelligent driving field in the world is far ahead. At present, the new M7 intelligent driving version of Wenjie has completed the OTA upgrade, and supports the functions of high-speed NCA and urban LCC. On high-speed and elevated roads, vehicles can follow the navigation to their destinations, and consciously identify the signal lights to assist in controlling normal driving, intelligent lane change, intelligent speed limit, etc., which greatly liberates drivers from manipulating characters. It can also show its talents in urban roads, cruise at a fixed speed, follow the car, cross corners, etc. in the traffic flow, and it can also realize automatic avoidance in and out of the lane, greatly improving driving safety and happiness. It is worth mentioning that Huawei also uses technology to make parking more self-free. Because of the launch of the custom parking function, users can drag and drop vehicle icons on the ground where parking is allowed but not marked. A temporary parking space is supported with the narrowest width of +0.4m, and there is no need to ask an old driver for parking.

Not only that, but the new M7 in space and interior also shows amazing strength. In terms of interior space design, the new M7 in Wenjie has gained more effective interior space with a smaller "pool" through excellent design and layout optimization, with a "room occupancy rate" of 66.3%, leading the same class, and both front and rear rows can get a very spacious and comfortable experience. Moreover, in order to further improve the experience of drivers and passengers, the seats of the new car are designed with 10 layers of comfort lamination, with a total foam thickness of 100mm, and four seats are equipped with ventilation, heating and massage functions as standard, which can bring drivers and passengers a comfortable experience like first class. In addition, thanks to Huawei’s strong technical strength, the car’s Xiaoyi intelligent assistant can greatly liberate the user’s hands, and the double-row nap function of the main and auxiliary drivers can be turned on through voice, bringing more comfort, intelligence and fun to the user’s travel experience. In addition, the new M7 also provides a six-seat layout, giving consumers more car choices.

From the perspective of users, Huawei not only provides high-quality products and services, but also cares about the needs and rights of consumers. The new M7 in the world has won the favor of consumers through Huawei’s unique marketing strategy and caring plan, and soon became a hot model in the market after listing. If you have a car purchase plan recently, you may wish to take a look at the new M7 in the world. Now you can enjoy the rights and protection of buying a car, so act quickly!

　　Workers’ Daily News (Reporter Zou Yiran) Watching live webcasts has now become a daily pastime for many people. However, the "golden anchor" with many fans may be "wet". Recently, the Internet Court in Hangzhou, Zhejiang Province made a judgment on a dispute case involving infringement of the right to disseminate works information on the Internet and unfair competition, and a software service company compensated 1 million yuan.

　　Plaintiff Aauto Quicker Company is the main operator of "Aauto Quicker APP". The defendant company is a service provider of live broadcast field control software. According to the original report, the live broadcast field control software service provided by the defendant can centrally control a large number of mobile phones, and batch use the "Aauto Quicker" account to praise, give gifts, comment and pay attention to the designated live broadcast room. The anchor who uses this software can manipulate the "fans" in the live broadcast room artificially, thus creating false popularity and popularity. The defendant’s behavior violated consumers’ right to know and choose, endangered public interests and constituted unfair competition. Therefore, the defendant was required to immediately stop unfair competition, immediately cancel all relevant Aauto Quicker accounts used by him to increase false popularity, and compensate for the loss of 4.56 million yuan.

　　The defendant argued that the plaintiff’s subject qualification was flawed and he had no right to file a lawsuit in this case. The defendant has taken the initiative to delete the controversial information of the website involved, stopped the litigation-related business activities and successively refunded the users. There is no malicious infringement, and the plaintiff has no right to cancel the relevant accounts. The alleged infringing software did not cause great economic losses to the plaintiff, and the number of accounts in Aauto Quicker, the number of live broadcasts and the profit made by the plaintiff were not true.

　　The court held that Aauto Quicker Company obtained data such as user visits, likes and comments by operating Aauto Quicker software, formed the time and stickiness of users’ use of Aauto Quicker software and products, gathered user traffic and realized benefits through traffic, all of which belonged to Aauto Quicker’s competitive advantage, and such commercial interests should be protected by law.

　　The defendant used the alleged infringing software to help Aauto Quicker anchor to make false propaganda about the number of attention, fans, likes and comments on its live broadcast, which led to obvious misleading of consumers, wrong cognition of fictitious data and user evaluation, affected the authenticity of data on Aauto Quicker platform, destroyed the algorithm evaluation and recommendation system of Aauto Quicker platform live broadcast room and the real and honest interactive ecosystem created by Aauto Quicker software, harmed the legitimate rights and interests of other operators and consumers, and disrupted the market competition order.

　　Judging from this case, the live broadcast field control software has evolved from the operation of cultivating virtual accounts in batches without real names in the initial stage to the centralized use for "brushing powder" and brushing amount of webcasts after obtaining the authorization of real accounts in batches on the platform, which increases the difficulty and cost of platform governance while facilitating the fraud of live broadcast traffic, and also nourishes the black and gray industrial chain of online account leasing and trading, and should strengthen regulation according to law.

　　In the end, the court ruled that the defendant’s behavior constituted unfair competition and ordered him to stop unfair competition and compensate for the loss of 1 million yuan.

　　Recently, the first Ideal Home Technology Day was held in Changzhou Intelligent Manufacturing Base, LI. Under the guidance of "dual-energy strategy", LI has made important breakthroughs in the research and development of smart space, intelligent driving and high-voltage pure electric platform. The ideal SS intelligent space with Mind GPT as the core and the ideal AD intelligent driving which will open the city NOA internal test this month have entered the era of large model at the same time. The ideal 800V high-voltage pure electric platform supporting 5C charging will open the 5G era of charging speed.

　　The ideal AD Max 3.0, which entered the era of big model, is growing and iterating at an unimaginable speed in the past. At the product level, the urban NOA function that does not rely on high-precision maps will be delivered to the internal test users in Beijing and Shanghai, so that users can have an ever-evolving "AI driver". In the second half of the year, the commuting NOA function will be opened to users, so that users can have their own "exclusive elevator", making commuting easier and more convenient. On the technical level, AI big model technology is used to deal with all the challenges in the scene, and all the problems can be efficiently iterated and finally solved.

　　Perception algorithm: like people, it does not depend on maps and recognizes everything.

　　The core of not relying on high-precision maps is to use BEV model to perceive and understand the road structure information in the environment in real time. Through a lot of training, the current BEV model has been able to generate stable road structure information in real time at most roads and intersections.

　　For complex intersections, the method is to use the self-developed NeuralPriorNet network (NPN network for short) to extract NPN features of intersections in advance. When the vehicle drives to the intersection again, the previously extracted NPN features are taken out and fused with the BEV feature layer of the vehicle-side perception model, and a perfect perception result is obtained.

　　The NPN feature is a bunch of neural network parameters, from which humans can’t directly understand the complex intersection shape, but the large model can. Compared with high-precision maps, NPN features have more information and higher confidentiality. It uses network model instead of artificial rules to understand and use environmental information.

　　It is not enough to understand the intersection. "AI drivers" have to understand the traffic rules of traffic lights at intersections, which is another difficulty of urban roads. The mainstream approach is to establish a set of rules and algorithms for traffic intentions of traffic lights and roads, but the ideal is to choose a large model to solve it.

　　An end-to-end TrafficIntentionNet network (TIN network for short) is ideally trained. There is no need to set any rules artificially, or even to identify the specific location of traffic lights. As long as the image and video are input into the TIN network model, the network can directly give the result of how the vehicle should go now — — Turn left and right, go straight or stop waiting. By learning the reaction of a large number of human drivers to the change of traffic lights at intersections, the TIN network model is trained, and good results are obtained.

　　As shown in the following figure, at the intersection, the TIN network gives the probability of different traffic intentions at the intersection in real time according to the input video image, and the maximum probability value is the actual use intention, which is completely consistent with the indication of the signal light. When the red light is on, the network output waiting probability value is the maximum, and the vehicle keeps waiting. When the green light is on, the left turn probability of the network output increases to the maximum, and the vehicle starts to turn left. Although the result looks simple, the technology behind it is very advanced.

　　In the face of common obstacles that may appear on the road, such as construction roadblocks, scattered objects, goods protruding from the back of trucks, etc., Occupancy network is used to accurately identify their boundaries and types. In recent months, the ideal Occupy network has been iterated wildly, and a lot of training miles have been "fed", and the content and accuracy of recognition have been greatly improved.

　　Regulation algorithm: free control like a human.

　　In order to make "AI drivers" make reasonable judgments like human drivers in driving decisions and trajectories, it is ideal to apply imitation learning method to the planning and control algorithm, and train a large number of drivers’ driving behaviors, so that the decision-making and planning of urban NOA can make judgments more like human drivers on the premise of ensuring safety and conforming to traffic rules.

　　For example, when the vehicle needs to turn right, according to the traffic rules, you can choose either of the two lanes after turning right to merge. However, by observing a large number of human driving trajectories, it is found that more than 90% users will take the right second lane instead of the right first lane, because the safety and efficiency of the right first lane are not as good as that of the right second lane directly, and the turning radius of the right second lane is larger, the turning process is more stable, and the family will be more comfortable. Therefore, the final result of the model’s learning and training at this intersection is also inclined to take the right two lanes.

　　Training platform: continuous evolution like human beings.

　　The evolution of large-scale model needs a powerful basic training platform to complete fast and efficient training and iteration. Ideal started the construction of training platform very early. Up to today, it has grown into an autonomous driving training cluster with 1200 PFLOPS computing power, and the mileage of autonomous driving training has exceeded 600 million kilometers.

　 　 　 　Urban NOA open logic

　　Whether a city can open the use of NOA mainly depends on the completion of NPN characteristics of complex intersections in the city. By counting the R&D platforms covered by NPN in cities, we can see the coverage of NPN now, and each point above represents a complex intersection that needs to make NPN features. Among them, green represents the NPN feature of the intersection, which has passed the test and verification and is available, red represents the NPN feature but needs to be verified, and gray represents no NPN feature. At present, there are many red NPN characteristic points all over the country, and there are many green NPN intersections in Beijing and Shanghai where early birds and test cars appear frequently. Next, after the early bird users join, these spots will turn green faster and faster, which means that more and more cities are open.

　　The commute you need more, NOA

　　Commuting to and from work is usually the most tiring time of the day and the time when driving assistance is most needed. If this road can be opened by NOA, it will solve the big problem. Therefore, it is ideal to introduce commuter NOA products that everyone needs more. With commuting NOA, you don’t need to wait for the NPN features of the whole city to be trained. You just need to set your own commuting route and learn NPN features by car, and you can use NOA functions on this route after learning. If you commute every day, the simple route can be activated within one week, and the more complicated route is expected to be enough to complete the training in 2-3 weeks.

　　It is estimated that commuting NOA can cover more than 95% of the commuting scenes of ideal car owners. During the use of NOA for commuting, each model will continue to be iteratively trained, and the better it is, the better the experience will be. With commuting NOA, it is like having your own "exclusive elevator" on the way to and from work, which is definitely the NOA function you need now.

　　This month, the ideal will open the NOA internal test of cities in Beijing and Shanghai, and early bird users can take the lead in using the NOA function of cities. In the second half of the year, it is ideal to open the commuting NOA function and more NOA areas in cities, so that every early bird user can use NOA navigation to assist driving during daily commuting.

　　All these are the advanced achievements brought by AI big model technology. Through the leading technical architecture and excellent iterative efficiency, AD Max 3.0 platform will gradually meet the needs of all cities and users to use NOA functions on urban roads. When commuter NOA and urban NOA expand on a large scale, it will be a "just-needed configuration" for mid-to high-end cars that can’t be sold well without equipment. (Photo courtesy of LI)
