The invention provides a limiting method, a limiting device and a limiting system for motor current of a vehicle. In the motor current limiting method, when a shift permission request of a shift transmission in a vehicle is changed from inactive to active, current limiting of a shift motor connected to the shift transmission in the vehicle is started, and normally, the shift motor is not activated. The gear shifting motor is changed from the torque mode to the rotating speed mode only after the gear shifting permission request of the gear shifting transmission is activated, so that the current limiting method of the motor is used for limiting the current of the gear shifting motor before the gear shifting motor is changed from the torque mode to the rotating speed mode; therefore, the current limitation on the motor can be earlier than the regulation and control on the output torque of the motor, and the possibility that the output torque of the motor is not controlled is further reduced.

    本申请提供一种车辆的电机电流的限制方法、限制装置、限制系统。在该电机电流的限制方法中,在车辆中的换挡变速器的换挡允许请求由未激活变为激活时,开始对车辆中与换挡变速器相连的换挡电机进行电流限制,而通常情况下,换挡电机在换挡变速器的换挡允许请求激活后才会由扭矩模式变为转速模式,因此该电机电流的限制方法在换挡电机由扭矩模式变为转速模式之前,就对换挡电机进行电流限制,从而使得对电机进行电流限制可能会早于对电机的输出扭矩进行调控,进而降低了电机的输出扭矩不受控的可能性。
