The invention relates to a vehicle motor control method. The method comprises the following steps: determining that a motor control unit MCU fails; monitoring the output alternating current frequencyof a motor; and controlling the motor to switch between an active short-circuit circuit state and a safety pulse turn-off state based on the output alternating-current frequency. The invention furtherrelates to a motor control circuit for the vehicle, a motor driving system and the vehicle.
本发明涉及一种用于车辆电机控制方法,所述方法包括:确定电机控制单元MCU发生故障:监测电机的输出交流频率;以及基于所述输出交流频率,控制所述电机在主动短路电路状态以及安全脉冲关断状态之间进行切换。本发明还涉及一种用于车辆的电机控制电路、电机驱动系统以及车辆。
