Li Auto leads the era of large models and intelligent driving enters a new stage

According to news on June 20, Li Auto recently announced the latest progress in smart driving and launched its new product Li Auto AD Max. 3.0, and announced that the car will enter a new era of large models. It is reported that within this month, Li Auto will deliver urban NOA functions that do not rely on high-precision maps to internal beta users in Beijing and Shanghai, and plans to open the commute NOA function to users in the second half of the year.

The launch of the commuter NOA function will subvert the traditional intelligent driving training method. This is the stance of Li Auto. Users only need to set their own commuting route and let the vehicle learn relevant features, and then they can use the NOA function on that route without waiting for the feature training of the entire city to be completed. Simple routes that are expected to take less than a week can be activated, while routes that are expected to take 2 to 3 weeks are more complex and require training.

According to the editor’s understanding, the core of the commuter NOA function is the use of BEV (Bird's Eye View) large model, which has the ability to generate stable road structure information in real time and is suitable for most roads and intersections. However, at complex intersections in cities, there is still a certain instability in relying solely on BEV large models for perception. To solve this problem, Li Auto has adopted the method of enhancing the BEV model with NPN (Neural PriorNet) features.

NPN features refer to intersection features pre-extracted by the vehicle. When the vehicle passes through the intersection again, the previously extracted NPN features can be combined with the BEV features of the vehicle-side sensing large model. Layers are fused to obtain more accurate perception results. Li Auto stated that their related work will be published at CVPR, the top international conference in the field of AI, detailing the technical principles and implementation methods of the NPN feature-enhanced BEV model.

Li Auto’s latest progress demonstrates their continued innovation and R&D efforts in the field of intelligent driving. By launching the commuter NOA function and enhancing the BEV model with NPN features, they are committed to providing a safer, more stable and smarter driving experience, and bringing users more convenient and comfortable travel options. With the ideal The launch of AD Max 3.0 has raised people’s expectations for future smart travel.
