China car companies can't adjust the air suspension properly, which has actually made BYD understand.

Friends who are familiar with overseas car modification culture should have heard of the very popular Lowrider style on the west coast of the United States: lowering the chassis of the car, installing an independent and controllable hydraulic suspension, and making the car dance like a disco:

Unexpectedly, this technology, which has long been monopolized by Hispanic riders in the United States, was "subverted" by BYD today. ...

Yesterday, BYD once again showed the super run named Looking Up at U9 at the press conference.

You see, is this feeling of independent suspension jumping a bit similar to Lowrider?

Accompanied by explosive music, this four-wheel suspension looking up at U9 can dance intelligently and harmoniously:

Even the unique stunt of "taking off in place" in the field of Lowrider modification was seized by this car. ...

And the four wheels fly together, making the whole car stay in the air (the picture is slow after high-speed photography):

BYD, have you learned to dance?

Yun Qi, the world's first intelligent body control system in China, makes this sports car jump like a low-altitude rider. In fact, it is the exclusive intelligent body control system of new energy released by BYD yesterday: Yun Qi.

NI ǐ N is an intelligent body control system developed by BYD for five years, with deep system-level integration and costing billions of yuan.

Looking up at U9, what we see is Yunnian -X fully active body control technology, which is an experimental and conceptual product series in this system.

The ladder -X is more than just jumping: even if one wheel is missing, it can still control the vehicle to continue driving smoothly and safely.

Some netizens even joked: Is BYD going to impact the dimension reduction of China tricycle track?

Jokes are jokes. What needs to be clear is that we should not see the actual installation of Yun Qi -X system on the real car launched for the market in the near future-after all, it is more a demonstration of BYD's technical strength to make the car jump than what consumers in the real market really need.

A truly market-oriented product matrix includes the following three series:

Yunnian -C: Intelligent damping body control system, whose working principle is to control the electromagnetic valve of shock absorber to adjust damping, and realize stepless adaptive adjustment of suspension damping, which breaks the limitation of passive operation and single adjustment of traditional automobile suspension system. Yun Qi -C focuses on the comfort and handling of vehicles, especially when accelerating, braking and cornering rapidly, which can quickly "harden" the chassis, achieve suspension coordination and body stability similar to that after installing anti-sway bars, and significantly improve the vehicle's sportiness.

Yunnian -A: Intelligent air suspension system. Its working principle is to quickly make decisions by collecting the data of on-board sensors, and quickly and accurately control the core components of air suspension system, including air intake and exhaust, stiffness conversion valve, shock absorber solenoid valve, etc. The adjustable stroke of Yunnian -A air suspension can reach 15cm, and its comfort, ride comfort and passability are all suitable for middle and high-grade cars.

Yun Qi -P: Intelligent hydraulic body control system is a high-performance integral suspension system developed by BYD for off-road and heavy-duty vehicles. It can adjust the stroke of 20 cm, realize four-wheel synchronization or single-wheel independent lifting, and is suitable for off-road driving scenes. Parking and camping can also be leveled. The lifting force of the system is 5 tons, and it can automatically switch between three different stiffness modes according to the driving situation, so as to ensure the comfort during smooth driving, improve the maneuverability during intense driving, and effectively reduce the impact force during off-road downhill.

Behind the intelligent body control system in Yun Qi, it is composed of intelligent detection architecture, intelligent computing center, intelligent control technology and key components.

Among them, the intelligent detection architecture includes behavior perception, body perception, road perception and other capabilities. It can identify the driver's intention by obtaining the steering wheel angle, pedal signal and so on. It can also use conventional sensors such as acceleration, altimeter and inertial measurement unit, as well as advanced sensing elements such as monocular camera and laser radar to detect the car condition and road surface in real time, thus significantly improving the adjustment speed and intelligence of suspension system and improving the ride experience in the car.

Especially, the intelligent electronic control frequency of the suspension system of Xiao Yun system can reach 1000 times per second.

For BYD or the industry, it is a good body control technology. Although we compared the culture of BYD and Lowrider at first, in fact, BYD's cloud technology has far surpassed the manual hydraulic suspension commonly used in Lowrider modified cars in terms of advanced degree and intelligence. In fact, it has basically approached and partially reached the level of overseas traditional high-end automobile suspension system manufacturers.

Yun Qi and BYD have created two firsts in the world and China: 1) the world's first exclusive intelligent body control system for new energy; 2) BYD became the first China company to independently master the R&D capability and end-to-end supply of intelligent body control system.

Yes, that is to say, BYD finally broke the long-standing dominance of overseas leading enterprises including ThyssenKrupp and Marpai in the field of intelligent (air) suspension systems.

Driven by domestic consumption upgrading and cost reduction, air suspension is no longer exclusive to luxury cars with a price of several hundred thousand yuan in the past, but has been regarded as optional or even standard by brand products of new cars in China.

However:

1) In the past, at the upstream end of the suspension system, especially the high-end intelligent air suspension system, the localization level of spare parts supply was still low, mainly occupied by enterprises from Russia, Japan and other countries in Europe.

2) It is precisely because of the low localization rate of parts and components that the market share of imported brands in intelligent air suspension products was once very high. Only from the perspective of system integration can China enterprises gain a certain market share.

Through the Year of Cloud, BYD's greatest success is also its greatest contribution to the automotive air/smart suspension industry in China. It is precisely because it, as a China company, has realized end-to-end independent research and development and deep integration at the system level for the first time, and solved the problem of vertical deadlock.

Just like the royal chariot in ancient China, the cloud car became the real body control system of China people. Wang Chuanfu, chairman and president of BYD Group, said that the birth of Yun Qi changed the history that body control technology relied on foreign countries, filled the domestic technical gap and achieved a breakthrough from zero to one.

At the same time, through the Yun Qi -X technology demonstration at the beginning of the article, BYD has demonstrated advanced functions such as 0-roll and pitch, three-wheel drive, vehicle dancing, etc.-The practicality of these functions really needs specific scenes, but at least it proves that BYD has found its own ideas and showed its muscles on the air suspension that Chinese enterprises have never understood.

Finally, it is worth mentioning that not long ago, when Wang Chuanfu bombarded autonomous driving as "all a fool", he was also resisted by some related industry experts and practitioners.

However, combined with the release of the cloud system, it can be seen that Wang Chuanfu is not shooting empty talk. He is actually telling us that the so-called "intelligence" in the era of smart cars is not necessarily the cockpit experience, intelligent automation or assisted driving, but it seems to be more lively today. BYD can also find its own intelligent way through the self-developed suspension control system Yun Qi with perception and intelligent decision-making.
