The Yunnian system is an intelligent vehicle system developed by BYD Automobile Company, which greatly improves the driving experience of consumers from the dimensions of comfort, handling, safety and off-road.
There are four grades C, A, P and X in total
-
Yunqi -C: It belongs to the damping body control system, and controls the damper solenoid valve to adjust the damping through the Yunqi Intelligent Computing Center in the car. It is currently installed in BYD Han, Tang and Tengshi D9 models, and will be upgraded to Yunqi -C through OTA later.
-
Yunqi -A: It belongs to the air body control system, and there will be an air storage tank at the rear of the vehicle. The flexibility and stroke of the suspension will be adjusted through Yunqi Intelligent Computing Center, so as to improve the comfort and support of the whole vehicle, and it will be mounted on Tengshi N7.
-
Yunqi -P: It belongs to the hydraulic body control system, and can realize the off-road functions of super-high lifting, four-wheel linkage and camping leveling. The adjustment stroke of the suspension is 200mm, the lifting capacity is 5t, and the maximum bearing capacity of key components is 53Mpa. It will be carried on the U8 for the first time.
-
Yunqi -X: It should be a system specially built for U9. At present, the relevant information has not been disclosed too much, but the "disco-style admission" of U9 really won the attention of many viewers.
To sum up, the benefits brought by the Yunnian system are to control the height, stiffness, damping, and main power of the car body through a set of intelligent algorithms so as to restrain the posture change of the car body, reduce the rollover risk of the car, reduce the sitting displacement of the driver and passenger, and maintain comfort and stability in a variety of complex road conditions, such as snow, mud, and water, and protect the car body and passengers.
On the other hand, it can effectively inhibit the attitude change of the body, even if only three wheels can drive smoothly. Greatly reduce the risk of vehicle rollover and reduce the driver and passenger sitting position displacement.
In order to achieve the above effect, Yunqi system has been self-developed in the fields of detection and perception, intelligent operation, intelligent control and core components. Among them, Yunqi Intelligent Exploration Architecture has 50+ sensors.
In the aspect of road surface perception, Yunqi preview system integrates multiple road surface sensing elements such as single/binocular camera and laser radar, which can identify the road surface features and elevation curves in the range of 5-150m in front of the vehicle, and the recognition accuracy is as high as 3 mm, and the recognition accuracy is over 99% within 15m.
On the whole, BYD's smart body control system is still very powerful at present. It can be equipped with different versions on different price models, which can give users a better experience. Yunnian technology has brought the safety ability to upgrade the vehicle.
