New energy vehicles and intelligence have formed an absolutely strong correlation, which includes smart cockpits, smart driving and smart chassis. In the process of consumers choosing a car, whether a car is smart or not has become very important. considerations. Take smart driving as an example. Last year, Yu Chengdong revealed that since the launch of Wenjie's new M7, the smart driving version has accounted for 60% of total sales, and the optional smart driving model in urban areas has been as high as 75%.
At present, the attitude of Chinese new energy vehicle consumers towards smart driving has rapidly changed from a wait-and-see attitude in the early years to a high level of recognition. Therefore, smart driving will become the soul of luxury new energy vehicles in the future. Looking at the field of intelligent driving, it is no exaggeration to say that Hongmeng Zhixing series models currently have absolute dominance in the three major aspects of function, experience, and safety.
One
In 2021, Huawei ADS 1.0 will be unveiled at the Shanghai Auto Show; in 2023, the Wenjie M5 smart driving version equipped with Huawei ADS 2.0 will be officially released; at the end of 2023, it will be the first to realize that it can be driven nationwide and can be driven wherever there is a road; by this year's ADS 3.0, which debuted from parking space to parking space, realizes full-scenario connectivity. Huawei has been leading the technology of intelligent driving systems and indirectly promoted the development of related industries.
At the 2024 Chengdu Auto Show Hongmeng Smart Technology Day, Huawei smart car solution BU ADS marketing expert W mentioned that smart driving is a game for the brave, not a short-term sprint race, but a marathon race that requires long-term Only with firm strategic investment can we reach the finish line.
From an industry perspective, intelligent driving technology includes three elements, data, algorithms and computing power. The amount of data is extremely large, and a huge data center is required to process this data. Algorithms are also iterating rapidly, and BEV/Transformer/end-to-end/large models are all in rapid development. There is also computing power. The computing power and data processing capabilities of the car terminal all require chips, etc. In summary, the difficulties faced are the large amount of data, fast algorithm iteration, and high cost of chip computing power.
Huawei ICT has long-term accumulation of core engineering capabilities, including AI, HiSilicon chips, operating systems, and software capabilities, as well as Ascend series algorithms and chips. This is Huawei's full-link vertical and deep integration. advantages. This is also the reason why Huawei ADS currently uses 1 TOPS of computing power to outperform others' 2 TOPS of computing power or even better, truly achieving 1+1 greater than 2.

From a technical perspective, the perception of ADS has gone through three iterations from BEV to GOD. 2.0 uses the GOD network and has universal obstacle detection capabilities. In 3.0, BEV and GOD are integrated into a larger GO.D network.
As for the back-end part, the GOD network to the PDP network form an end-to-end technical architecture, which gives the smart driving system a higher upper limit and can handle more complex scenarios, but it also means a lower lower limit, but Huawei believes that The foundation of smart driving should be safety. In response to security issues, ADS 3.0 introduces an instinctive security network, which is a big difference from the industry. The instinctive safety network is like our hand touching the flame, which will instinctively be withdrawn, similar to this mechanism. Our end-to-end network is based on safety priority, so ADS 3.0 can not only handle more complex road conditions, but also has safer emergency response capabilities.
End-to-end onboarding also means that the capabilities of the smart driving system will advance by leaps and bounds, which relies on using massive amounts of data for algorithm training. Huawei’s current cloud computing power has reached 5E FLOPS, and the smart driving system can learn 35 million+ per day. kilometers, allowing the intelligent driving system algorithm to iterate every five days to achieve rapid growth.

Relying on the powerful perception and integrated control capabilities of ADS, Huawei has also launched the Touring platform, a digital travel control system that integrates intelligent driving, chassis, and vehicle domain control. Its application range spans A-level to E-class models currently include the Zhijie S7, Wenjie M9 and Xiangjie S9.
The core of the Touring platform is perception and fusion control. The Touring platform itself is a combination of software and hardware, which contains three parts. The first is multi-dimensional synergy. This synergy is mainly hardware, which includes suspension, drive, braking and steering; the second part is Revolving around intelligent digital platforms, including software and hardware, such as E The DC variable damping shock absorber corresponds to the Hongmeng system, and the MDC is the controller of smart driving; the third part is the car control system corresponding to the domain controller of the car control. Here is the perception part, the cockpit, smart driving, and the tradition of the vehicle. The sensors also detect the road conditions through fusion recognition.
At the same time, Bitauto was also invited to participate in the Hongmeng Smart Technology Day interview event and interviewed W, marketing expert of Huawei's smart car solution BU ADS, and Wang Yanmin, president of Huawei's terminal smart car selection business unit.

ADS 3.0 media QA part
Question 1: From a technical point of view, what is different about L3?
Answer: L3 has a lot of redundancy. It has algorithmic redundancy and can quickly switch when a failure occurs. In addition, chassis, wire control, braking, etc. also need redundant design. According to current regulatory requirements, redundant hardware must beYes, the cost may be more expensive.
Question 2: After Huawei’s pure vision solution cancels lidar, how to ensure the safety of the intelligent driving system?
Answer: To correct you, Huawei has canceled the ADS basic version of lidar. It is not a pure visual solution, but a main vision solution. It still uses fused perception. In addition to lidar, the basic version has the high penetration and high penetration of ultrasonic radar and millimeter wave radar. Advantages of long detection distance.
Question 3: From a research and development perspective, what do you think of the pros and cons of smart driving and how do you evaluate it?
Answer: Taking parking as an example, the speed and recognition rate of parking space scanning, parking speed, etc. can all show the advantages and disadvantages of the technology. Take high-speed smart driving as an example. Under normal circumstances, especially with high-precision maps, everyone is OK. However, in order to reduce costs, some manufacturers omit the two millimeter wave radars on the side and rear. Millimeter wave radars can see longer distances, so the risk is relatively high when changing lanes at high speed.
Question 4: The current intelligent driving system is very cautious when dealing with various situations, even at the expense of efficiency. Are you considering introducing driving modes with different efficiencies based on different scenarios?
Answer: This is a standard triangle model of the autonomous driving industry - safety, experience and efficiency. It is still difficult to achieve a balance between these three. Regarding the mode issue, we now have three modes to choose from.
Question 5: Can Huawei ADS Basic Edition have 3.0 end-to-end functions? Can all current models of Hongmeng Smart be upgraded to OTA 3.0?
Answer: Mainly the high-speed and parking functions, which are very close to the high-end version. In urban areas, we have only launched LCC and LCC Plus functions now. Because it is subject to some hardware and safety considerations, it lacks a laser and a rearview camera, so it does not provide intelligent driving capabilities on particularly complex urban roads.
Question 6: The latest lidar currently has 192 lines. Will the next step be to further improve the response speed of lidar in terms of active safety?
Answer: By 2025, we will launch a new generation of lidar to improve performance, reduce costs, and achieve deeper coupling with our ADS 4.0 algorithm. L3 has higher security requirements, and the security of L3 urban areas must also be higher.
Touling platform QA part
Question 1: How does our Touring platform solve the different tuning orientations of different models?
Answer: The Touring platform consists of two parts, software and hardware. First of all, we have requirements for partners’ hardware platform selection, including some chassis configurations, which are aligned with each other. In addition, we will definitely make adjustments according to different models and different scenarios. For example, we will pay attention to what the target users of this product need and pay more attention to, and then use the Touring platform to make it more outstanding.
Question 2: Touring PlatformWill you cooperate with companies outside the Hongmeng Zhixing brand?
Answer: First of all, let’s be clear about a concept. Huawei has no plans to develop or design a chassis. We only focus on the Touring platform. This platform includes some of our core software and hardware, as well as the traditional body and chassis systems of our partners and suppliers. Therefore, in general, it is called the Touring platform. We believe it is the core component for traditional cars to become intelligent and electrified.
The Touring platform currently has no plans to open to partners outside the "four circles" of smart car selection. Now Huawei is focusing more on the continuous evolution of the platform itself. We still focus more on the Touring platform’s adaptability to various road conditions and scenarios, and on improving driving response.
Question 3: Hongmeng Zhixing is a traditional OEM. If they need to adjust their products, can they adjust it themselves?
Answer: In the past, when adjusting a chassis, it was necessary to clearly define whether it was a sports car or a comfortable car, whether it was for home use or commercial use at the early stage of product definition. The long-term definition was clearly stated, and then a suitable chassis was selected. If not, it may need to be redesigned. to develop the chassis. In the Touring platform, Huawei jointly develops it with its partners. Because traditional car manufacturers have a large number of engineers and they have excellent technology, while we have intelligent technology, we can integrate our concepts together and leverage our respective strengths for joint development.
In fact, our adjustment path with our partners still follows the test-feedback process. We believe that now is an era of continuous integration and evolution. For example, when we say whether bushings are good or not, this condition is still needed, because we still have to use bushings and springs... these still have to rely on traditional car manufacturers. Of course, the superposition of motors, braking force, air suspension, EDC continuously variable damping suspension, etc. must be added together to polish it.
We hope to do system planning under the Touring platform in the future. We have unified design and adjustment planning for EDC, air suspension, including some automatic steering devices, so that the capabilities of the OEM and ours can jointly move up to a new level.
