The invention provides a chassis control method and a chassis control system, and belongs to the field of vehicle chassis control. The chassis control method comprises the steps that operation parameter information of a vehicle is collected; determining a corresponding required yaw torque according to the required operation parameter information through each control model, wherein each control model corresponds to each preset use condition; the total demand yaw torque of the vehicle is calculated according to all the demand yaw torques; acquiring the current yaw torque execution capability of each actuator of the vehicle; and according to the total demand yaw torque, the current yaw torque execution capability of each actuator and a preset distribution rule, determining a target yaw torque of each actuator, so that each actuator outputs the corresponding target yaw torque. The invention further provides a chassis control system corresponding to the chassis control method. According to the chassis control method and system, the stability and safety of the vehicle can be guaranteed.

    本发明提供了一种底盘控制方法及底盘控制系统,属于车辆底盘控制领域。该底盘控制方法包括:采集车辆的运行参数信息;通过各个控制模型分别根据其所需的所述运行参数信息确定相应的需求横摆扭矩,每一所述控制模型对应于每一预设使用工况;根据各个所述需求横摆扭矩计算所述车辆的总需求横摆扭矩;获取所述车辆的各个执行器当前的横摆扭矩执行能力;根据所述总需求横摆扭矩、各个所述执行器当前的所述横摆扭矩执行能力和预设分配规则确定各个所述执行器的目标横摆扭矩,以便各个所述执行器输出相应的所述目标横摆扭矩。本发明还提供了与上述底盘控制方法对应的底盘控制系统。本发明的底盘控制方法及控制系统能够保证车辆的稳定性和安全性。
