On December 10th, LI officially released OTA 5.0, and announced that it plans to start full user push on December 19th. Through three software upgrades: intelligent driving (AD Max 3.0), intelligent space (SS 3.0) and intelligent extended range (REV 3.0), OTA 5.0 has brought comprehensive evolution of product strength to the ideal L-series car, becoming the strongest OTA in LI history.
Intelligent driving platform, the ideal L-series Max model is upgraded to AD Max 3.0, and the full scene intelligent driving (NOA), full scene assisted driving (LCC), intelligent parking and active safety capabilities are fully upgraded. On the intelligent space platform, Mind GPT big model opens the internal test in SS 3.0, making ideal students become car assistants, travel assistants, entertainment assistants and "encyclopedia teachers" of the whole family. At the same time, the sensing and control algorithm of the intelligent extended range platform ushered in key optimization. REV 3.0 helped the ideal L series to increase the pure electric cruising range by 15%-20% in winter, and the whole family could have a worry-free mileage in cold winter.
At the same time, Li ONE’s OTA 3.4 is also scheduled to be launched on December 26th, adding functions such as traffic light countdown of Gaode map, mobile version of task master, co-pilot screensaver, parking photo overhead view and energy consumption distribution statistics.
"Every OTA is an experience innovation that we bring to users. In the past 14 months, LI has experienced 20 OTA version upgrades, and launched heavy functions such as task master, tuning master, voiceprint recognition and small master mode, which brought surprises to users again and again. " Li Xiang, Chairman and CEO of LI, said, "OTA 5.0 is a big iteration of the ideal L-series model, and the technical ability and product experience brought by AD Max 3.0 will make a qualitative leap, bringing a safer, more comfortable and more convenient intelligent driving experience to the family. The new Mind GPT in SS 3.0 empowers ideal students, deeply integrates with vehicles, and truly becomes a member of the family, so that every family member can easily enjoy AI in the car. At the end of 2023, OTA 5.0 was the best New Year gift we brought to users. In the new year, we will bring more OTA upgrades and strive to become the first choice for families and grow together with users. "
Intelligent driving breaks the ceiling of the whole scene
AD Max 3.0 simplifies the complexity, integrates the functions into four items: full-scene intelligent driving, full-scene assisted driving, intelligent parking and active safety, and has a wider open area and more applicable scenarios, providing users with a product experience that breaks the ceiling of the intelligent driving industry.
Relying on excellent intelligent driving hardware and accumulated training mileage on a larger scale, LI intelligent driving platform began to switch to the end-to-end algorithm architecture based on large model. BEV model and Occupancy, which are leading in the visual field, occupy the network to make the perception more accurate; The planning algorithm is gradually switched to the spatio-temporal joint planning algorithm, and the optimal driving trajectory is planned in milliseconds; MPC model predictive control algorithm brings low time delay, high precision steering and acceleration and deceleration, and balances safety, comfort and traffic efficiency well.
Full-scene intelligent driving can be opened nationwide.
After upgrading OTA 5.0, full-scene intelligent driving will cover all highways and urban loops in China, as well as urban roads in 110 cities. Whether in urban areas or highways, the performance of intelligent driving in the whole scene is closer to that of "old drivers". In the congested urban roads, vehicles can fully perceive, accurately predict and skillfully deal with complex game scenes such as traffic jam, lane change and mixed traffic at intersections. At the same time, the safety of full-scene intelligent driving in high-speed scenes has also been upgraded. In the face of dangerous construction scenes, special-shaped work vehicles or extreme traffic jams, it can be bypassed or avoided in time to ensure driving safety.
Full scene assisted driving can be opened all over the world.
AD Max 3.0′ s full-scene assisted driving function has the ability to cope with all kinds of complex traffic conditions on a global scale, bringing more surprises to users. Without setting navigation, full-scene assisted driving can recognize hundreds of different types of traffic lights by means of TIN end-to-end traffic light network, and realize the start and stop at intersections, even at complex and long-distance intersections.
In addition, the large model brings a powerful "brain supplement" ability to the whole scene assisted driving function. Even on the road with fuzzy lane lines or even no lane lines, a stable virtual lane line can still be formed according to the road edge and the trajectory of the preceding vehicle, and the traffic can be successfully completed. In the face of more difficult bends and diverging and merging lanes, as well as various obstacles on urban and rural roads, the powerful ability of full-scene assisted driving can effectively cope with them.
Smart parking is better than parking.
AD Max 3.0 also brings users a comprehensive upgrade of smart parking, so that family travel is no longer worried about parking. After the BEV model and Occupancy network algorithm are introduced into the panoramic fisheye camera, the surrounding environment of the vehicle is accurately identified, and the whole vehicle is free of blind spots when driving at low speed. Heuristic planning search algorithm and MPC control algorithm also significantly improve parking efficiency.
With the newly added parking function, users can operate the vehicle by their mobile phones after getting off the bus, and even if they park in a very narrow parking space, they don’t have to worry about the inconvenience of getting on and off. The more powerful parking service function can help users remember the designated parking spaces in the multi-storey underground parking lot and park them automatically, with the upper limit of the supported span reaching 10 floors. When driving to the parking space, it should deal with difficult scenes such as narrow right-angle bends and circling passages. Vehicles have the ability to flexibly choose routes, and even make room for smooth traffic by reversing.
Actively and safely avoid high-frequency and high-risk traffic accidents
In the safety field that home users attach the most importance to, LI takes avoiding high-frequency and high-risk traffic accidents as the active safety research and development goal, and develops the industry-leading AEB function to create an umbrella for the whole family. LI has established a perfect driving risk database based on the local road conditions in China, and classified it according to the frequency and risk level, focusing on solving the high-frequency and high-risk risks that users really encounter.
Thanks to the BEV big model algorithm, the AEB capability of AD Max 3.0 has achieved a leap, and the remote sensing accuracy has been significantly enhanced. The working speed covers 4-135 km/h, providing full-speed domain guarantee for driving safety. Facing pedestrians and stationary vehicles, AD Max 3.0 can stop at 110 km/h and 120 km/h respectively. Even in the low-speed tricycle scene neglected by the industry, AD Max 3.0 can still stop at 80 kilometers per hour. Moreover, the AEB false trigger rate of AD Max 3.0 has been reduced to less than once every 300,000 kilometers, exceeding the industry standard, and taking into account traffic efficiency and comfort while protecting the safety of the whole family.
Intelligent space completely reshapes interactive experience.
In the newly upgraded SS 3.0, Mind GPT, a multimodal cognitive model, started internal testing, which was truly tailored around the car scene and networked in real time, giving ideal students more new roles such as car assistant, travel assistant, entertainment assistant and encyclopedia teacher. Combined with the new full-time wakeup-free ability, command freedom, concise mode and re-evolved dialect freedom of ideal students, SS 3.0 completely reshapes the interactive experience of smart space and allows AI to enter more families.
LI built the original base model of Mind GPT from 0 to 1, and its structure adopted the self-developed TaskFormer neural network architecture. Based on the scenes of car use, entertainment and travel, he used SFT, RLHF and other technologies to train, which enabled Mind GPT to have three abilities: understanding, generation, knowledge memory and reasoning. In the authoritative evaluation list of Chinese big language model C- EVAL and CMMLU, the powerful Mind GPT won the first place. Based on the key scenes of home users in cars, LI has also customized more than 1,000 exclusive abilities for Mind GPT, covering 111 fields, which is a dimensionality reduction blow to the traditional car voice assistant by the large model ability.
Accompany the whole family with car assistants, travel assistants and entertainment assistants.
The ideal student is first of all a professional car assistant, who can provide professional answers to any questions about vehicle operation, state inquiry or fault diagnosis. The new AI task master function allows ideal students to understand complex function combinations and automatically create tasks. Regardless of their elders or children, every family member can use the task master at zero threshold and become the product manager of LI.
When a family goes out, the Ideal Homecoming Association is an effective travel assistant, providing family members with travel inspiration, planning trips, searching for good places to eat, drink and have fun in the newly added Meituan application, and its recommended location and route can also be directly called in the navigation, making self-driving travel more arbitrary. On the way out, the ideal classmate is also a funny commentator who can patiently explain the historical and cultural stories of scenic spots along the way for his family.
At the same time, the ideal classmate is also an interesting entertainment assistant, who can check the current news, star trends, popular movies and songs that family members want to know online and provide the latest information. The film and music works mentioned in the ideal students’ answers can also be directly played by calling related applications on the car side.
Encyclopedia teachers and painting masters are practical and interesting.
In addition, the knowledgeable ideal classmate is also a knowledgeable encyclopedia teacher. Mind GPT’s knowledge reserve covers all fields of natural science, history and culture, from children’s strange 100 thousand whys to the latest scientific and technological digital products that adults pay more attention to, and it is still growing.
What’s even more surprising is that Mind GPT can not only answer questions, but also be creative. Write a poem, tell a story, and then draw the described scene. The requirements put forward by these children can be met by all-round ideal students.
The dialogue efficiency of ideal classmates will be upgraded again.
In addition to adding more roles after being empowered by the big model, the bottom quality of the ideal students has been improved again, and their listening and execution abilities have evolved in an all-round way. SS 3.0 brings full-time wakeup-free ability to ideal students, and can directly send common voice commands to ideal students without saying wakeup words. Ideal students have also added the function of freely speaking instructions. If a sentence contains multiple instructions, ideal students can identify them one by one and execute them one after another. After upgrading SS 3.0, the ideal students’ voice response will also support the concise mode of "less words", and the scope of dialect free speaking will be expanded again, and a number of new functions will be combined to significantly improve the dialogue efficiency between users and ideal students.
More possibilities for car browser opening
In addition, SS 3.0 also brings the car browser application, which makes richer music, videos and cloud games create more possibilities for the in-car entertainment experience. Thanks to the deep integration of the browser and the car system, the global media player, the ideal classmate voice interaction and the Bluetooth gamepad can all adapt to the browser, so that the powerful browser functions can be seamlessly integrated into the smart space.
Intelligent extended range surprise upgrade winter battery life
In winter, LI continuously iterates through the algorithm, and continuously improves the endurance of the ideal L-series vehicles from OTA 4.6.2. After upgrading OTA 5.0, REV 3.0 has brought a 15%-20% increase in pure electric cruising range for L-series models, making the family’s winter travel bid farewell to mileage anxiety.
The ideal L series is equipped with a full-stack self-developed XCU vehicle central domain controller, which is the first to adopt an A-core intelligent chip in the field of vehicle control, and provides a solid foundation for the algorithm iteration of REV 3.0 with strong computing power. Innovative intelligent power prediction algorithm can accurately predict the discharge power of batteries and motors in milliseconds, and achieve more accurate discharge control, which can not only ensure the safety of vehicles, but also fully release the potential of batteries and improve the maximum discharge capacity by 4.1%. For vehicle-mounted electrical appliances with high power consumption, such as air conditioning and seat heating, the new algorithm optimizes the power consumption through smarter detection and control means, and greatly improves the power efficiency while ensuring comfort.
OTA 5.0 push plan
OTA 5.0 is scheduled to be fully pushed to the ideal L-series vehicles from December 19th, 2023. In terms of intelligent driving, Max models will take the lead in upgrading AD Max 3.0, and Pro and Air models plan to upgrade AD Pro 3.0 in June 2024 to realize high-speed intelligent driving (NOA), full scene assisted driving (LCC) and more intelligent parking and active safety under BEV architecture. In terms of smart space and intelligent range extension, Max, Pro and Air models will upgrade SS 3.0 and REV 3.0 simultaneously.
