摘　　要：针对车辆电机扭矩上升速率过快,导致整车拖拽感加剧、差速器烧蚀等问题,提出基于电机转速闭环控制的电力牵引力控制系统(ETCS),利用电机转速快速识别滑转状态。实车测试结果表明:该系统能够在传统驱动防滑功能激活前主动降低驱动扭矩,抑制车轮滑转率,从而有效消除整车拖拽感,保护差速器。In order to solve the problems of aggravated drag feeling and differential ablation caused by the rapid rise rate of vehicle motor torque,this paper proposes an Electric Traction Control System(ETCS)based on closed-loop control of motor speed,which uses motor speed to quickly identify the slip state.Vehicle test results show that the system can actively reduce the driving torque and suppress the wheel slip rate before the traditional drive anti-skid function is activated,so as to effectively eliminate the dragging feeling of the whole vehicle and protect the differential.
