Abstract
The present application relates to a method, device, equipment, storage medium and vehicle for controlling a vehicle suspension, and relates to the field of vehicle control technology. A method for controlling a vehicle suspension comprises: receiving a suspension parameter request message sent by a controller. The suspension parameter request message comprises the position information of a target vehicle and the vehicle driving information of the target vehicle. In response to the suspension parameter request message, the target road that the target vehicle is about to enter is determined based on the position information of the target vehicle, and the road information of the target road is obtained. Based on the road information of the target road and the vehicle driving information of the target vehicle, the target configuration parameters of the suspension in the target vehicle are determined. The target configuration parameters comprise the damping of the suspension and the target height of the vehicle body during the target vehicle's driving on the target road. The target configuration parameters are sent to the controller. This is used to solve the hysteresis problem of active suspension adjustment.
