Abstract: This application discloses a motor control unit, a power train, a control method, and an electric vehicle, and relates to the field of electric vehicle technologies. An input end of the motor control unit connects to a power battery pack, an output end of the motor control unit connects to three phases of motor windings of a motor, and the motor control unit includes an inverter circuit and a controller. The controller is configured to control the inverter circuit to simultaneously output currents to the three phases of motor windings, and control the currents input to all the phases of motor windings to sequentially reach a preset current.
