The invention provides a controller for a driving motor and related equipment thereof, the driving motor exchanges heat with a power battery through a cooling loop, the driving motor comprises a three-phase stator winding, and the power battery supplies power to the three-phase stator winding through an inverter circuit; the controller responds to the condition that the temperature of the power battery is larger than or equal to the preset battery temperature and controls the output current of the inverter circuit so that the driving motor can output torque to drive wheels. The controller responds to the situation that the temperature of the power battery is smaller than the preset battery temperature, adjusts the output current of the inverter circuit according to the comparison result between the voltage of the power battery and the preset battery voltage, and controls the output current of the inverter circuit to enable the heating value of the three-phase stator winding of the driving motor to be increased. By implementing the application, the power battery can be heated by using the heating value of the driving motor, so that the cost is reduced.
