On December 10, Li Auto officially launched OTA 5 at the intelligent software conferenceVersion 0, which mainly includes intelligent driving (AD Max 3.)0), smart space (SS 3.)0) and intelligent range extender (rev 3.)0) Three major software upgrades, and these are also called "the strongest OTA in the history of Li Auto".
It is understood that the assisted driving platform has been upgraded to AD Max 3 for the MAX model of the ideal L seriesVersion 0, which comprehensively upgrades the capabilities of All-Scene Intelligent Driving (NOA), All-Scene Assisted Driving (LCC), Intelligent Parking, and Active Safety. In terms of smart space, the Mind GPT model has been developed in SS 30 has been launched to further improve the intelligence of the conversation. In addition, the sensing and control algorithms of the range extender platform increase the pure electric range of the Ideal L series by 15%-20% in winter.
In addition, for old car owners, Ideal has not stopped updating.
Ideal ONE's OTA 34 will be launched on December 26, and a number of new functions have been added, such as the traffic light countdown of AutoNavi Map, the co-pilot screensaver, the top view of parking photos, energy consumption distribution statistics and the mobile version of the task master.
In the past 14 months, Li Auto has released 20 OTA version upgrades, adding several features. Looking ahead, Li Auto plans to bring more OTA upgrades in 2024 to continuously improve the car experience for car owners.
Intelligent driving AD MAX 30
In this OTA, the ideal intelligent driving system AD MAX 30 has also ushered in an upgrade, integrating functions into four categories: full-scene intelligent driving, full-scene assisted driving, intelligent parking and active safety. After upgrading to OTA 5After 0, full-scene intelligent driving will cover all highways and urban ring roads in the country, as well as urban roads in 110 cities. Even in congested urban roads, the Ideal L series can fully perceive, accurately and skillfully cope with various complex game scenarios.
ad max 3.The all-scene assisted driving function of 0 is very intelligent and does not require setting up navigation. This feature recognizes hundreds of different traffic light styles with the help of the TIN end-to-end traffic light network to start and stop at 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 has also been upgraded.
After the introduction of the BEV large model and the occupancy network algorithm into the surround view fisheye camera, the vehicle's recognition of the environment is more accurate, and the parking efficiency is also effectively improved. The new off-the-car parking function allows the owner to operate the vehicle through the mobile phone to complete the parking by himself after getting out of the car, and there is no need to worry about the inconvenience of getting on and off the car even if he parks in a very narrow parking space.
The valet parking function can also help users memorize the designated parking spaces in the multi-storey underground parking lot and automatically park in, supporting a span of up to 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.
With the support of the BEV large model algorithm, AD Max 3The AEB capability of 0 has also been effectively improved. In particular, the long-range perception accuracy and working speed cover 4-135km h. For pedestrians and stationary vehicles, it is possible to brake at speeds of 110 and 120 km/h, respectively. Officially, the ideal AD Max 3The 0 AEB false trigger rate has been reduced to less than 1 per 300,000 km, which is a rare achievement.
Smart Space SS 30
Newly upgraded SS 30 brings the internal testing of the multi-modal cognitive model Mind GPT, and the real-time networking enables ideal students to realize multiple roles such as car assistant, travel assistant, entertainment assistant and encyclopedia teacher. It provides professional answers to any questions about vehicle operation, status inquiries or troubleshooting.
As a self-developed multimodal cognitive model, Mind GPT is the original base model of Mind GPT built from 0 to 1, and its structure adopts the self-developed TaskFormer neural network architecture, and a series of training is carried out based on SFT, RLHF and other technologies in scenarios such as car use, entertainment, and travel. Mind GPT has the three major abilities of comprehension, generation, knowledge memory and reasoning.
At present, MIND GPT has tailored more than 1,000 exclusive capabilities covering 111 fields based on the key scenarios of ideal students. And the new version of the ideal student supports the ability to speak dialects freely, command to speak freely, concise mode, and full-time and full-time car without wake-up.
In addition, SS 30 also brings in-car browser applications, allowing richer ** and cloud gaming to create more possibilities for in-car entertainment experience. Thanks to the deep integration of the browser and the car machine system, the global *** device, the voice interaction of ideal classmates, and the Bluetooth gamepad can all be adapted to the browser, so that the browser function can be seamlessly integrated into the intelligent space.
Smart Range Extender Rev 30
Upgrade to OTA 5 through algorithmsAfter 0, rev 30 has brought a 15%-20% increase in winter pure electric range for L series models.
It can be said that Li Auto is the first car company to adopt A-core intelligent chips in the field of vehicle control, and it is a full-stack self-developed XCU vehicle domain controller. On the one hand, the computing power is improved, and on the other hand, it also emphasizes the determination of Ideal in the field of intelligent range extension.
It is reported that the ideal in the industry pioneered the intelligent power algorithm, which can achieve accurate battery and motor discharge power, and is millisecond-level, so it achieves more accurate discharge control, which can not only ensure the safety of the car, but also fully release the limit capacity of the battery, and increase the maximum discharge capacity by 41%。The advantage of this is that it not only increases the pure electric range, but also improves the acceleration performance under the same operating conditions.
In addition, it also has a series of optimization algorithms for the power used by on-board electrical appliances, which greatly improves the efficiency of electricity consumption by monitoring and intelligently controlling electrical appliances such as air conditioning and seat heating, ensuring comfort and greatly improving power efficiency.
For this upgrade, Ideal said that from December 19, 2023, OTA 50 will be fully pushed to the ideal L series models. In terms of intelligent driving, the MAX model will be the first to upgrade to the AD MAX 30, while the Pro and Air models are scheduled to upgrade to the AD Pro 3 in June 20240, to achieve high-speed intelligent driving (NOA), all-scene assisted driving (LCC) and more capable intelligent parking and active safety under the BEV architecture. In terms of smart space and smart range extension, the MAX, Pro and AIR models will be upgraded to SS 3 at the same time0 and rev 30。
Write at the end
This time the ideal OTA5The 0 upgrade has brought significant changes in functionality and experience, which can be regarded as taking the automotive software function to a new level. Its launch will undoubtedly bring users an unprecedented intelligent driving experience and a more intelligent life. In the future, Li Auto will continue to promote the development and application of intelligent technology to bring users a more convenient, efficient and safe travel experience.
