Embodiment Construction
[0040] figure 1 It is a flow chart of a motor active heating control method for a vehicle according to an embodiment of the present invention. Such as figure 1 As shown, the motor active heating control method for the vehicle includes:
[0041] Determine whether the vehicle has a heat demand;
[0042] Detect the running status of the vehicle;
[0043] If the vehicle has heat demand and is in a static state, the direct axis current of the control motor is DC current, and the quadrature axis current of the control motor is zero;
[0044] Wherein, when the direct axis current of the motor is DC current and the quadrature axis current of the motor is zero, a constant magnetic field parallel to the rotor magnetic field of the motor is formed inside the motor, and the motor has no torque output.
[0045] Here, the heat demand refers to the place on the vehicle that needs heat, such as the passenger compartment, which needs to increase the temperature to ensure the comfort of the...
