提出了一种基于主动前轮转向(AFS)和直接横摆力矩控制(DYC)协同工作的控制策略,以提高车辆的稳定性控制效果。设计了基于滑模变结构控制的AFS控制器及基于最优控制的DYC控制器,在此基础上设计了一个协调控制器,该控制器根据逻辑门限值统一协调AFS和DYC的工作。仿真结果表明:采用此协调控制策略,可比单独采用AFS更好地维持车辆的稳定性。 A control strategy based on active front wheel steering (AFS) and direct yaw moment control (DYC) is proposed to improve the stability control of vehicles. AFS controller based on sliding mode variable structure control and DYC controller based on optimal control are designed. Based on this, a coordination controller is designed, which coordinates the work of AFS and DYC according to the logic threshold. The simulation results show that using this coordinated control strategy can maintain the stability of the vehicle better than using AFS alone.
