Owner: It's like a different car
Written by Wang Lei
This may be the "most beautiful" launch to date.
Held last night".The strongest OTA ever"At the press conference, the keynote speaker wasSong ZiweiIn September this year, the good-looking product manager resigned from the vivo sub-brand iQOO and announced that he would join Li Auto. After this news came out, it caused a lot of waves in the car circle at that time.
After all, Song Ziwei has accumulated a large number of fans in the mobile phone circle, and with a pair of long legs, she attracted countless fans at the press conferenceBring powder into the group
Three months after joining the company, Song Ziwei ushered in her debut, although the specific position was not disclosed, but this wave of traffic has been pinched by ideals.
This press conference is also of great significance to the ideal, in addition to the Song thigh with its own halo, the content of the conference is more hardcore, Li Xiang himself also announced on the social platform that the ideal car city NOA (automatic assisted navigation driving) process exceeded expectations.
ota 5.How strong is 0?
Song Ziwei used a very old metaphor, and the upgrade is greater than the operating system we are familiar withWindows 95 to Windows XP elevation, "Caught up with a big iteration of the product".
For example, for autonomous driving, the MAX model of the Li L series has been upgraded to AD MAX 30, after the upgrade, intelligent driving can be opened nationwide, and assisted driving can be used all over the worldThe ability to drive intelligently directly enters the first echelon
The MIND GPT model was also officially put on the bus, which made the dialogue between ideal classmates more efficient, and Song Ziwei spoke Guankou and Biao dialect on the spot, and she could also deal with multiple instructions in one breath.
To the surprise of many car owners, after the upgrade, the ideal car will also have an on-board browser function, in the owner's own words, just like a different car.
Intelligent driving that can be driven all over the country and the world
After Song Ziwei appeared on the stage, she took the lead in introducing intelligent driving AD30。
Regarding the progress of ideal intelligent driving, Li Xiang made a move on the social platform "Versailles" at the end of November, "The original plan was to cover 100 cities by the end of the year AD Max City NOA 'internal beta version'I'm sorry we lost our words
But in fact, the ideal will directly launch the "official version" of the all-scene intelligent driving NOA, covering the national highways and ring roads and 100 cities, and the all-scene assisted driving LCC can be used worldwide and fully delivered to AD MAX users.
Unexpectedly, this data was updated at the press conference and became110 cities
According to Song Ziwei, upgrade OTA 5After 0, full-scene intelligent driving will be coveredAll highways and urban ring roads in the country, as wellUrban 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".
Obviously, Li Xiang, who complained that he had invested half a year late in intelligent driving, had caught up in a short period of time.
Introduction of BEV
From ad 20 full upgrade to AD 30, the core algorithm model has been re-architected, from the original modular algorithm architecture based on multiple small models and artificial rules, to the end-to-end algorithm architecture based on large models.
The upgraded intelligent driving has a wider open area, more applicable scenarios, and stronger system capabilities and efficiency, and has begun to keep up with the first echelon.
In terms of perception algorithms, it is more advanced in the field of visionBEV large models and occupancy occupy the networkThe planning algorithm is gradually switched to the spatio-temporal joint planning algorithm, and in ideal terms, the optimal driving trajectory can be planned in milliseconds.
At the same time, it has also been updatedMPC Model ** Control Algorithm, to achieve low delay, high accuracy of steering, acceleration and braking, more able to balance safety, comfort and traffic efficiency.
At the press conference, Song Ziwei also brought a section of her own use of urban NOA to challenge the evening rush hour in downtown Beijing.
In congested urban roads, in the face of complex game scenarios such as lane changes and mixed traffic at intersections, the whole process of vehicle perception, ** and execution is quite smooth.
At the same time, the safety of full-scene intelligent driving in high-speed scenarios has also been upgraded, and it can bypass or avoid in time in the face of dangerous construction scenes, special-shaped operation vehicles or extreme plugs to ensure driving safety.
Overseas is possible, too
At this press conference, Ideal also a**A section of driving in Kazakhstan was filmed**, and it can be seen from ** that even on the road without lane lines on snowy days, Ideal can also be based on the current environmentSimulate exit lane markings
This is made possible by AD30 full-scene assisted driving with the blessing of the large model".Brain supplementEven on roads where the lane lines are blurred or there are no lane markings, it can still form a stable virtual lane line according to the road edge and the trajectory of the vehicle in front, and successfully complete the traffic.
In the face of more difficult curves and divergences, merging lanes, as well as various obstacles on urban and rural roads, the powerful ability of all-scenario assisted driving can be handled.
It can be driven all over the world, and it has also become the slogan of Li Auto's full-scene assisted driving.
It has the ability to deal with all kinds of complex traffic situations on a global scale. Without setting up navigation, full-scene assisted driving can recognize hundreds of different styles of traffic lights with the TIN end-to-end signal light network, and not only can identify special-shaped traffic lights, but also the speed control in the traffic light switching stage has also been optimized, even in complex and long-distance intersections.
Smart Parking
In addition to driving, the ability to park an ideal car has also been improved. As for how good it is, Song Ziwei is also willing to bow down, sayingBetter than parking yourself
In fact, in the face of increasing body size, the scene encountered when parking will inevitably become an expected pain point.
Thanks to the ideal willThe BEV large model and occupancy network algorithm were introduced into the surround view fisheye cameraThe surrounding environment of the vehicle can be accurately identified, so that there is no blind spot in the whole vehicle when driving at low speed. The heuristic planning search algorithm and MPC control algorithm also significantly improve the parking efficiency.
In dealing with difficult scenarios such as narrow right-angle bends and circling passages, the vehicle has the ability to flexibly choose the route and even passReversing to make way for space and staggering
In addition, the new off-the-car parking function allows users to operate the vehicle through their mobile phones to complete parking by themselves after getting out of the car. For example, when facing a narrow parking space, users can get out of the car in advance to avoid embarrassing situations.
The valet parking function upgraded from the exit parking is supported at mostUp to 10 floorsspan. In fact, this largely solves the problem of tight parking spaces and complex passages in shopping malls that you often have to face when you are shopping and traveling.
It is worth mentioning that these functions can only be used in the L series models.
In the end, the ideal also took the initiative to talk about itAEB capabilities, with the blessing of the BEV large model algorithm, AD30 AEB capabilities have made great progress, working speed coverage4-135km/h。In the test, AD max 30 For pedestrians and stationary vehicles, it can brake at a speed of 110 km h and 120 km h respectively.
Even in the case of encountering a low-speed tricycle, AD 30 can also be used to brake at speeds of up to 80 km/h. According to Song Ziwei's introduction, ad max 3The AEB false trigger rate of 0 has been reduced to less than 1 per 300,000 km.
Li Auto has even established a high-frequency and high-risk driving risk scenario library based on domestic local road conditions, which is divided intoThere are three levels: low, medium, and high, almost all the scenes you can imagine are covered.
It is not difficult to see that the core of this intelligent driving upgrade is its ability to introduce a large BEV model, and the greater significance of this press conference is to let everyone see that the ideal has made up for the previous shortcomings and began to move towards the first echelon of intelligent driving.
The in-car version of Chat GPT was born
When you upgrade OTA 5After 0, you will find that your ideal classmate is no longer a student, but a teacher.
The car machine has introduced the ideal self-developed oneMultimodal cognitive model Mind GPThas capabilities similar to ChatGPT, Google Bard, and other generative AIs.
In fact, it is not a new thing for voice assistants to access large models, at least in the mobile phone circle, but in the automobile circle, the ideal is at the forefront this time.
In the Chinese large language model evaluation list C-Eval, Mind GPT won the first place among the 58 participating large models; At the same time, there is also an evaluation list of 67 subject areas covering from basic disciplines to advanced majors, and CMMLU ranks first.
Mind GPT is on the car, I don't know if you think this function is frivolous, but the ideal does show off its skills in this matter, such as AI solving arithmetic problems, AI painting, and AI copywriting.
In fact, this is not the first appearance of the ideal mind GPT's capabilities.
You can go and flip through the Weibo of Li Xiang, CEO of Li Auto, in the past six months, most of his Weibo has come from".iPhone client for Mind GPT
The structure of the Mind GPT model adopts the self-developed TaskFormer neural network architecture, and uses SFT, RLHF and other technologies for a series of training based on scenarios such as car use, entertainment, and travel, and has three major capabilities: understanding, generation, knowledge memory and reasoning.
To put it simply, it's letVoice interaction just got smarterHe can answer more questions from you, can be your life and car assistant, and can be identified in the car according to the intonation and rhythm of our daily speech, how much you say, he can recognize the key words, can understand your orders more accurately, and supportMultiple rounds of dialogue, contextual comprehension, and even dialect confusion
At this point, Song Ziwei has already shown a wave at the press conference in a variety of dialects.
Of course, like other GPT models, Mind GPT can give you some creative answers, but any large language conversation model has data and time limitations, and the answers it gives are not absolutely accurate.
At the end of the press conference, Ideal also brought an upgrade that can be called one of the most practical ones this time, and the intelligent range extension has also been upgraded to 3Stage 0 (rev3.)0）。
Although in essence, the intelligent range extender 3The work done by 0 is also the optimization of the algorithm, but it is also thanks to the ability of the BEV large model, and the ideal has developed a setAlgorithms for Smart Power**, can be millisecond accurate ** battery and motor discharge power, so as to achieve more accurate discharge control, to ensure safety while releasing the potential of the battery, will be the mostThe large discharge capacity has been increased by 41%
For high-power-consuming on-board appliances such as air conditioners and seat heating, more intelligent detection and control methods are also used to optimize the use of power, ensure comfort and improve power efficiency.
The end result is an increase in the all-electric range of the L-series models in winter
That's it for the ideal OTA 50 main highlights, the official will be fully pushed on the ideal L series models from December 19. After this press conference, the most complained about intelligent driving shortcomings of the ideal will finally be filled.
