About Yunlin Intelligent Body Control SystemIt includes the Yunlin-C intelligent damping body control system, the Yunnan-A intelligent air body control system, the Yunnan-P intelligent hydraulic body control system, and more technical product series will be launched in the future to enrich the product line. It is the core selling point of BYD's current chassis technology.
The Yunlin-C system can receive thousands of signal inputs in seconds, and the processing time of the Yunlin Intelligent Computing Center is as fast as microseconds, which can realize the rapid adjustment of the damping of the shock absorber, and can help the vehicle achieve a vibration isolation rate of 96% under the condition of continuous vibration road surface at 60km h, providing users with a more comfortable riding experience. This is the characteristic of Yun Yuan C.
At present, BYD's models equipped with Yunnan-C include BYD Tang, Han, Song L, Denza D9, N8 and other models, and I have driven most of them. This chassis system is mainly in the speed bump and cornering, through the rapid adjustment of the shock absorber damping to achieve higher stability and comfort, can well suppress roll, bounce, pitch and other states, so as to bring the driver and passengers more comfortable riding performance, compared with the traditional passive suspension, Yun Yuan-C in the driving comfort of better control.
The Yunnan-A system can adjust the height, stiffness and damping by controlling the air spring intake and exhaust, stiffness conversion valve, shock absorber solenoid valve, etc., to realize the dynamic adjustment of the body control, and the suspension adjustment stroke can reach 150mm, and the system provides more than ten functional modes to achieve active adjustment.
At present, I have also driven the Denza N7 equipped with this chassis technology, and the handling and comfort have indeed been upgraded compared to the models equipped with Yunnan-C, after all, it is air suspension, and then there are front double wishbones and rear multi-link independent suspension, so that the overall hardware level looks not bad. Of course, there is also the condiment of ICVC intelligent vector control technology, which makes this chassis look more fragrant.
In the N7 route, the damping is infinitely adaptively adjusted by means of electronically controlled shock absorbers. In comfort mode, the system responds to road conditions such as pulsed road surface and random road surface with high-frequency and small damping, improving the overall smoothness of the vehicle. In Sport mode, the system responds to emergency braking, full-throttle acceleration, high-speed cornering and other working conditions with low-frequency and high-damping to improve vehicle handling. The Yunlin-A is the killer feature of the current DENZA N7.
Yun Yuan-P is the strongest BYD chassis we can see at present, equipped on the U8, although it has not been driven yet, but from the hard power on paper, this car and chassis are absolutely not bad. The suspension adjustment stroke of the Yunnan-P intelligent hydraulic body control system can reach 200mm, which is 50mm more than the Yunnan-A, which can not only realize the synchronous lifting capacity of four wheels, but also realize the independent lifting of a single wheel. The lifting force of the system is as high as 5 tons, which can meet the needs of high-intensity off-road continuous lifting5 tons of weight.
We all know that looking up to the U8 car is high and big, what should I do if I encounter a parking lot height limit? At this time, you only need to turn on the ultra-low mode, and you can easily pass 1With a height of about 9 meters, 99% of the parking lots in the country are no problem. If you want to get out of trouble, there is also a super high mode, which can also help you get out of trouble with a powerful torque burst after opening.
Leopard 5 is actually also equipped with Yunlin-P, when camping, the vehicle is in a stationary state, and the height of a single wheel can be adjusted to make the plane of the body and the direction of gravity always remain vertical, so as to achieve the level in the car, and further improve the comfort of uneven road surface when camping, which is still very good.
On the whole, the current BYD Yunyuan intelligent body control system is still very powerful, and it is equipped with different versions on models at different price points, which can give users a better experience. I'm already looking forward to the Yunlin-X.
