Abstract

The invention provides an active suspension control system and method, and relates to the technical field of automobiles. The active suspension control method comprises an information acquisition vehicle, a current driving vehicle and a cloud platform; the information acquisition vehicle is used for acquiring first road surface smoothness information, and sending the first road surface smoothness information to the cloud platform; the cloud platform is used for receiving the first road surface smoothness information sent by the information acquisition vehicle and sending the first road surface smoothness information to the current driving vehicle; and after the current driving vehicle receives the first road surface smoothness information sent by the cloud platform, target damping force used for controlling an active suspension system is determined according to the first road surface smoothness information. According to the embodiment of the invention, the active suspension system is controlled through the road surface smoothness information obtained from the cloud platform, so that the problem of control hysteresis is effectively solved, and the drivability and comfort of the vehicle are ensured.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an active suspension control system and method. Background technique [0002] At present, automobile suspension systems are divided into two types: passive suspension and active suspension. The traditional passive suspension fixes the damping characteristics of the shock absorber before the vehicle leaves the factory and cannot be adjusted, while the active suspension control system can be adjusted according to different Based on the comprehensive judgment of the road conditions, the driver's emergency operations (acceleration / braking / steering) and the real-time vehicle movement, it adjusts the damping force of the shock absorber in real time to achieve ride comfort and handling stability. [0003] The active suspension control system can control the body movement under various road surfaces based on the judgment of vehicle state information such as wheel acceleration, body a...
