摘　　要：为了充分发挥分布式驱动电动汽车电机扭矩响应迅速及力矩独立可控的特点,采用底盘稳定性协调控制方法,通过电子稳定性系统与扭矩矢量控制单元的协调控制处理各类工况下车辆的稳定性需求,即通过扭矩矢量控制单元(TVCU)单独控制提高车辆处于稳定条件下的动态性能,通过电子稳定性控制(ESC)系统保证车辆趋于不稳定时的动力性及稳定性,并基于实车验证了该稳定性协调控制方法的鲁棒性。In order to give full pay to the advantages of rapid torque response and independent controllable torque of the distributed driven electric vehicle,this paper adopted the chassis stability coordination control method,through the coordinated control of the electronic stability control system and the torque vector control unit to deal with the stability requirements of the vehicle under various working conditions-improve the dynamic performance of the vehicle under stable conditions through TVCU independent control,ensures the power and stability of the vehicle by ESC when it tends to be unstable.The robustness of the stability coordination control method was verified based on a real vehicle.
