Intelligent driving breaks the ceiling of the whole scene
ad max 3.0 simplifies the complex, integrates the functions into four categories: full-scene intelligent driving, full-scene assisted driving, intelligent parking and active safety, opens up a wider area, applies more scenarios, and provides users with a product experience that breaks the ceiling of the intelligent driving industry.
Relying on high-performance intelligent driving hardware and larger-scale cumulative training mileage, Li Auto's intelligent driving platform has begun to switch to an end-to-end algorithm architecture based on large models. The leading BEV large model and occupancy network in the field of vision make perception more accurateThe planning algorithm is gradually switched to the spatio-temporal joint planning algorithm, and the optimal driving trajectory is planned in millisecondsThe MPC model** control algorithm delivers low-latency, high-precision steering, acceleration and deceleration, providing an excellent balance between safety, comfort and traffic efficiency.
All-scene intelligent driving, which can be driven nationwide
Upgrade OTA 5After 0, full-scene intelligent driving will cover all highways and urban ring roads across the country, as well as urban roads in 110 cities. Whether it is in urban areas or highways, the performance of full-scene intelligent driving is closer to that of "old drivers". In congested urban roads, in the face of complex game scenarios such as lane changes and mixed traffic at intersections, vehicles can fully perceive, accurately and skillfully respond. At the same time, the safety of full-scene intelligent driving in high-speed scenarios has also been upgraded, and in the face of dangerous construction scenes, special-shaped operation vehicles or extreme plugs, it can be bypassed or avoided in time to ensure driving safety.
Full-scene assisted driving, which can be driven all over the world
ad max 3.The full-scene assisted driving function of 0 has the ability to deal with all kinds of complex traffic situations on a global scale, bringing greater surprises to users. Without the need to set up navigation, full-scene assisted driving can rely on the TIN end-to-end signal light network to recognize hundreds of different styles of traffic lights, realize the start and stop at intersections, and go straight through even complex and long-distance intersections.
In addition, the large model brings a powerful "brain supplement" ability to the full-scene assisted driving function, even on roads where the lane lines are blurred or there are no lane lines, a stable virtual lane line can still be formed according to the road edge and the trajectory of the vehicle in front, and the traffic can be successfully completed. In the face of more difficult curves, diversion and merging lanes, as well as various obstacles on urban and rural roads, the powerful ability of all-scenario assisted driving can effectively deal with it.
Smart parking is better than human parking
ad max 3.0 also brings users a comprehensive upgrade of smart parking, so that family travel no longer bothered by parking. After the BEV large model and occupancy network algorithm are introduced into the surround view fisheye camera, the surrounding environment of the vehicle is accurately identified, and the whole vehicle has no blind spots when driving at low speeds. The heuristic planning search algorithm and MPC control algorithm also significantly improve the parking efficiency.
With the new off-the-car parking function, users can operate the vehicle through their mobile phones to complete the parking by themselves after getting out of the car, and do not have to worry about the inconvenience of getting on and off the car even if they park in extremely narrow parking spaces. The more powerful valet parking function can help users memorize the designated parking spaces in the multi-storey underground parking lot and automatically park in, and the upper span of support reaches 10 floors. When driving to the parking space, the vehicle has the ability to flexibly choose the route in response to difficult scenarios such as narrow right-angle bends and circling passages, and can even make room for smooth passage by reversing.
Actively and safely avoid high-frequency and high-risk traffic accidents
In the field of safety, which is most important to home users, Li Auto takes the avoidance of high-frequency and high-risk traffic accidents as the R&D goal of active safety, and develops industry-leading AEB functions in the whole stack to create a protective umbrella for the whole family. Li Auto has established a comprehensive driving risk database based on China's local road conditions, and graded them according to frequency and risk, focusing on solving the high-frequency and high-risk risks encountered by users.
With the support of the BEV large model algorithm, AD Max 3The AEB capability of 0 has achieved a leap, the long-distance perception accuracy has been significantly enhanced, and the working speed covers 4-135 km/h, providing full-speed guarantee for driving safety. In the face of pedestrians and stationary vehicles, ad max 30 can achieve braking at speeds of 110 and 120 km/h, respectively. Even the low-speed tricycle scenario, which has been overlooked by the industry, AD Max 30 can still brake at speeds of up to 80 km/h. Not only that, ad max 3The AEB false trigger rate of 0 has been reduced to less than 1 time per 300,000 kilometers, exceeding the industry standard, and taking into account the efficiency and comfort of traffic while protecting the safety of the whole family.
