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. An input end of the inverter circuit is the input end of the motor control unit, and each phase of output end of the inverter circuit connects to one phase of motor winding of the motor. 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. According to the motor control unit, a heat generation capability of the motor windings is fully used to heat the power battery pack, symmetry and reliability of the motor are ensured, and a case in which an additional heating apparatus is used to heat the power battery pack can be avoided, and therefore occupied space and costs are reduced.
