Changan invested 65.438+0 billion yuan in L4-class autonomous driving for mass production in 2025.

Financial Network Automotive News? Recently, Changan Automobile's L4 automatic line control platform project with a total investment of 654.38 billion yuan was officially launched. The project is expected to achieve mass production in 2025, and it is expected to achieve an annual output of more than 500,000 L 1-L4 intelligent driving products.

The L4 autopilot project started this time is based on the development of changan CS55 electric version. Compared with L3 autopilot technology which has been mass-produced, L4 autopilot will be applied to more complex scenes, and the range and accuracy of perception, the computing power of computing platform, decision-making planning and control performance will be greatly improved, thus optimizing the bicycle intelligent and vehicle-road cooperative autopilot system.

The L4 autopilot of Changan Automobile is mainly equipped with five 16 line laser radars (two in the front, one in the front and one in the back), 1 4 line laser radars, which are located in the middle of the front two 16 line laser radars, six optical cameras (four panoramic cameras and two remote cameras), an inertial navigation system and a high precision.

Changan Automobile's L4-class automatic driving can also realize remote automatic pickup and return of the car. Users can pick up the car remotely through the mobile APP, and the car will stop out of the parking space and automatically drive to the user's location; After the user returns the car through the APP, the vehicle will automatically drive to the free parking space to complete the automatic parking, and solve the problems of finding a parking space, parking, picking up the car and returning the car in an integrated way.

Chang 'an layout automatic driving

As early as April 20 16, a modified test vehicle in Chang' an was in? 5? Driving during the day? 2000? Km from Chongqing to Beijing to participate in the auto show, which opened the prelude to the automatic driving process of Changan Automobile.

Subsequently, in 20 18, Changan Automobile's L2-class autopilot technology was mass-produced, and PA-class autopilot key technologies such as adaptive cruise and fully automatic parking were integrated for mass production and research and development. Among them, fully automatic parking technology has been introduced on the CS75 18 production model, and integrated adaptive cruise technology has been introduced on the new CS55 production model.

In August of the same year, Changan Automobile L3 Limited Autopilot Technology is rapidly advancing engineering development, and it is expected to achieve mass production in 2020.

2065438+July 2009, Changan Automobile signed a five-party strategic cooperation agreement with China Telecom Chongqing Branch, Datang Mobile, China Automotive Engineering Research Institute and Chongqing Xiantao Data Valley Company, announcing the official opening of the 5G Autopilot Open Road Scene Demonstration Operation Base, the first domestic public service platform for 5G Autopilot, and starting the L4-level autopilot demonstration operation.

L4 automatic driving means that vehicles can drive themselves without human intervention in limited roads and environments. This restriction requires not only cars, but also road conditions, such as traffic lights that can communicate with WiFi. If the vehicle is separated from these road hardware support, it will lose its automatic driving function, and at present, China's laws do not allow self-driving vehicles to go on the road at will.

L4 Changan Yidong, previously tested by Changan Automobile, mainly relies on its own sensing system to obtain road information. The interconnection between vehicles and traffic facilities, as well as with surrounding vehicles, still mainly depends on short-distance communication methods such as WiFi.

Many car companies recommend L4 autopilot research and development.

20 19 12, Volkswagen announced that it will launch L4-class self-driving electric buses in Doha, Qatar, at the end of 2022, including 35 self-driving ID buses that can carry up to 4 passengers. Buzz and 10 Scania bus that can carry more people.

Volkswagen said in an official statement that the above-mentioned self-driving electric buses will start closed testing in 2020, open testing in 20021year, and officially put into operation at the end of 2022.

BMW also demonstrated its L4 autonomous driving technology on 20 19. The vehicle is based on the sixth generation BMW 7 Series model, and users can summon the vehicle through smart phones and automatically drive to the designated destination.

In addition, iNext, which BMW plans to launch in 202 1, will have L3 autopilot capability and technically support L4 autopilot. By 2024, BMW will officially mass-produce L4-class self-driving vehicles, making the automatic driving of high-speed and urban sections a reality.

With the addition of 5G, vehicles can use high-precision navigation maps to realize wide-area hardware communication interconnection, receive information and dispatch from the cloud, and even remotely control vehicles.

At present, due to the support of communication hardware in road environment, it will take time to realize L4 unmanned driving on a large scale.

Some insiders told Caijing Auto that L4-level autopilot is more advanced than L3-level autopilot, and there is no need for manual operation in the whole process, so it needs more sensor support, and the hardware requirements for the driving environment are also very high. Therefore, it will take time to realize large-scale L4 autopilot. Combined with the actual domestic car environment and urban road conditions, it is easier to achieve in some specific areas, such as logistics industry and small-scale car environment in closed parks.
