BYD shows off! AI large models are on the car, City Navigation Q1 push, and their “iMessage” is also launched

BYD has recently gone out of its way to engage in smart driving.

It all starts with a Weibo post by Zhao Changjiang, general manager of Denza Sales Division.

In October 23, Zhao Changjiang posted on Weibo that he had experienced the high-speed NOA function of Denza N7 and said that it was "very easy to use" and "smart driving is two generations ahead". It is even more powerful in curves with large curvatures. It claims to be the "first echelon in the industry".

According to Zhao Changjiang, the Denza N7's performance is inseparable from the combination of BYD's "Eye of the God" and Yunnan-A.

"This is an innovative result based on our self-research on chassis, smart driving and other dimensions, which can realize the complete intelligence of the car from the bottom up, " Zhao Changjiang said.

At that time, the series of "self-developed innovative results" he mentioned had not yet been disclosed to the outside world, so Ai Faner and Dong Chehui did not spend too much time reporting on them. But tonight, the road paved by BYD for intelligence has been opened.

Tonight, the 2024 BYD Dream Day was officially held, releasing a new strategy for the intelligent development of its new energy vehicles – vehicle intelligence.

The intelligence of the whole vehicle is the real intelligence.

Wang Chuanfu, Chairman and President of BYD Group, officially released BYD’s new achievement in the direction of intelligence, Xuanji Intelligent Architecture .

BYD Vice President Yang Dongsheng said in a follow-up introduction that the Xuanji architecture consists of one brain, two terminals, three networks and four chains. It is an important part of vehicle intelligence and allows the car to have an intelligent "brain" and "neural network" ”.

With the "brain", the next step is physical perception. Generally speaking, when we think of perception, we think of various smart driving sensing components such as lidar, cameras, and millimeter-wave radar. But in fact, the perception of a vehicle is much more than these, and also includes factors such as driver status and weather.

Through Xuanji's intelligent architecture, BYD's vehicle intelligence breaks the barriers between different systems and captures environmental changes inside and outside the vehicle in real time. Its "brain" will think about the information and make decisions in milliseconds, quickly adjusting the vehicle's "body" ” status, thereby improving the safety and comfort of driving.

Xuanji intelligent architecture depicts BYD's intelligent picture in three dimensions: intelligent driving, intelligent chassis, and intelligent cockpit.

The first is the perception level of intelligent driving.

BYD has begun to increase investment in large-scale full-scene perception fusion models in recent years. It has added BEV and Occupancy fusion perception based on the original 2D algorithm perception, and is also continuing to conduct cloud training.

Wang Chuanfu said that so far, BYD has delivered more than 6 million vehicles equipped with smart cockpits and more than 2.6 million vehicles equipped with L2 intelligent driving assistance. These BYDs running on the streets together form the largest company in the industry. Data base. BYD has implemented data mining using large car-side models, and has accumulated more than 300,000 high-value scenarios.

According to BYD's plan, the U8 and Denza N7, which support the "Eye of God" high-end intelligent driving assistance system, will receive a major round of OTA upgrades in the first quarter of this year.

Specifically, U8 will add new functions such as close valet parking, high-speed piloting, narrow passage, accelerator prevention, and easy parking in all directions. (The most distinctive one is Easy Sifang Parking, which will be discussed later). Denza N7 will add city navigation, mobile phone remote parking, intelligent driving interaction optimization, high-speed navigation, etc.

In addition, U8 will also add intelligent speed limit and lane centering assistance in the second quarter of this year, urban navigation assistance will be launched in the third quarter, and Denza N7 will complement narrow lane passage, short-distance valet parking, etc. in the second quarter. Looking up at the features on the U8.

The intelligent chassis level is BYD's "traditional strength." Based on the full-stack self-developed execution system combined with unique control technologies such as Yisifang, Yunnan, and DMO, BYD has established a fully independent and controllable diversified execution system. Coupled with physical sensing and multi-modal algorithms, it can ensure that the vehicle is not unstable on uneven roads, even in extremely dangerous situations such as high-speed tire blowouts.

The Easy Sifang Parking just mentioned is an excellent embodiment of perception combined with car control. When looking up at the U8 and facing an extremely narrow side parking space, the driver can directly plunge the front of the car into the parking space, and then use the ability of Yi Sifang to swing the rear of the car sideways into the parking space.

In terms of smart cockpits, which it has not been very good at in the past, BYD has introduced the long-prepared Xuanji AI large model.

Like the Mind GPT previously released by Li Auto, with the support of the Xuanji AI large model, the semantic recognition of BYD's DiLink cockpit has reached a new level. It can not only achieve temporary route planning and full vehicle control like Li Auto's classmates , and also added the function of smooth connection of multiple vehicles.

After enabling this function, the system will establish point-to-point vehicle contact through VIN, and can send instant messages to related vehicles through the on-board voice assistant without opening any application. It can be called "BYD's iMessage".

If you are careful from the end to the beginning, you will never fail.

This sentence from the "Tao Te Ching" says: If you always act cautiously and stick to the end, there will be no such thing as failure.

BYD's caution and conservatism in intelligence have always been interpreted by the outside world as "no technology and no ability." However, the actual situation is that in the first half of 2023 alone, BYD invested more than 14.2 billion yuan in research and development. , higher than the three "Weixiaoli" companies combined, and even exceeded Tesla's 12.3 billion yuan.

For an OEM that has invested over 100 billion yuan in total, has more than 90,000 R&D engineers, 11 research institutes, submits an average of 19 patent applications every working day, and has obtained 15 patent authorizations, "no technology" is a problem. The three words themselves are already an incredible fallacy. In fact, BYD's conservatism in intelligence largely stems from Wang Chuanfu's own cautious style.

I am down-to-earth, I am a strategist, and I can see things clearly than anyone else. If I don’t see clearly, this company will fail.

At BYD's 2022 financial report exchange meeting, Wang Chuanfu said that he "spent tens of thousands of engineers" to see whether driverless driving would work.

As early as 2013, BYD teamed up with the School of Mechanical and Vehicle Engineering of Beijing Institute of Technology to launch a remotely controlled wire-controlled autonomous vehicle experimental platform in just three months, realizing driverless functions.

In 2016, BYD also participated in the drafting of the "Intelligent Connected Vehicle Technology Roadmap 1.0". At that time, there were already two schools of thought: the progressive route and the leap-forward route. Most OEMs adopted the progressive route, gradually improving autonomous driving functions through the accumulation of data, while most start-up companies and Internet companies chose to enter the competition from the advantages of software and soft law. , trying to get it right in one step.

By 2018, BYD began to cooperate with Baidu, Huawei, Sagitar Juchuang, Horizon and other companies to develop autonomous driving technology on its jointly developed vehicle certification platform. BYD Qin Pro is the first autonomous driving development platform certified by Baidu Apollo.

At the same time, the platform is also an open source vehicle intelligence development platform that can provide developers with open interfaces, vehicle data and control permissions. This was the "BYD D++ open ecosystem" at that time.

However, when the bubble burst and investment enthusiasm subsided, Wang Chuanfu, who had been planning for autonomous driving for many years, realized that he was going in the wrong direction.

That frivolous thing (unmanned driving) is all deception. How many years has it been deceiving? How many of them have succeeded?

Now no one mentions it anymore, self-driving is all nonsense, now it is advanced assisted driving, nothing more, it is an advanced configuration in driving assistance, and it is passed down as a mysterious thing by the industry.

It was the Emperor's New Clothes, coerced by capital, but no one spoke of it at the beginning.

Miao Wei, former minister of the Ministry of Industry and Information Technology, once publicly stated that in the future, the realization of autonomous driving will still have to be promoted by the government. "Only when policies are implemented first can it be useful." Wang Chuanfu, who had found the right direction, made a very cost-effective choice at that time and gave priority to investing resources in the three-power technology.

At that time, Wang Chuanfu decided to let the bullets fly for a while. Furthermore, BYD's consumer group at that time did not have a large demand for assisted driving, and reckless stacking of materials would have an impact on the terminal selling price.

But now BYD's brand matrix has covered everything from household to luxury, from mass to individual:

In 2023, BYD Han sold an average of nearly 20,000 units per month, and BYD Tang models exceeded 10,000 units; Denza D9 won the MPV sales championship in the Chinese market in 2023, and the Yangwang U8, the first model of the Yangwang brand, achieved success in its first full delivery month Sales of 1,593 units were achieved; Leopard 5, the first model of the Fang Leopard brand, sold 5,086 units in its first full month of delivery…

BYD, it's time.
