IT Home reported on December 19 that the ideal car intelligent software conference held on December 10, Ideal OTA50 was officially unveiled, including intelligent driving, intelligent space, and intelligent range extension, and was launched today for the ideal L series models.
IT Home learned that Li Auto OTA 50 upgraded AD Max and AD Pro platforms, from AD 20 Full upgrade to AD 30。It has been upgraded from a modular algorithm architecture based on multiple small models and artificial rules to an end-to-end algorithm architecture based on large models.
ad max 3.0 In terms of perception algorithm, the BEV large model and occupancy network are used;The planning algorithm is gradually switched to the spatio-temporal joint planning algorithm, and the optimal driving trajectory can be planned in millisecondsAt the same time, the MPC model** control algorithm has also been updated to achieve low latency and high accuracy in steering, acceleration and braking.
ad max 3.0 supports all-scene intelligent driving (NOA), all-scene assisted driving (LCC), and newly upgraded intelligent parking, which can help users park their cars in designated parking spaces in underground parking lots, and even drive across layers, not only across 2 underground floors, but also 10 underground floors.
The Ideal L-Series MAX model will be upgraded to AD MAX30, support full-scene intelligent driving, covering national highways, urban ring roads, and urban roads in 110 cities. In the first half of next year, the Pro and Air models will realize high-speed intelligent driving, all-scenario assisted driving, and enhanced intelligent parking and active safety under the BEV architecture.
Ideal students introduced the beta version of the self-developed multi-modal cognitive model Mind GPT, and conducted a series of training based on SFT, RLHF and other technologies based on scenarios such as car use, entertainment, and travel. Mind GPT has the three major abilities of comprehension, generation, knowledge memory and reasoning.
Based on the key scenarios of ideal students, Mind GPT has tailored more than 1,000 exclusive capabilities covering 111 fields. The new version of the ideal student supports the ability to speak freely in dialects, speak freely in commands, concise mode, and free wake-up in all vehicles at all times.
Li Auto OTA 50 Upgrade the battery control algorithm, optimize the battery discharge capacity, and increase the maximum discharge capacity by 41%；The timing of range extender intervention is optimized to increase the proportion of pure electric useIntelligently adjust the power of the air conditioner, automatically adjust the optimal power of the air conditioner in real time, and increase the pure electric mileage. Officially, the pure electric range in winter has increased by 15-20%.
