The invention discloses a motor active heating control method and system for a vehicle and the vehicle, and relates to the technical field of vehicles. The motor active heating control method for thevehicle comprises the steps of judging whether the vehicle has a heat demand or not; detecting the running state of the vehicle; if the vehicle has a heat demand and is in a static state, controllingthe direct-axis current of the motor to be direct current, and meanwhile, controlling the quadrature-axis current of the motor to be zero, wherein when the direct-axis current of the motor is direct 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 in the motor, and the motor has no torque output. Theinvention further provides a corresponding control system. Meanwhile, the invention further provides a vehicle which adopts the control method to control heating of the motor or comprises the controlsystem. When the whole vehicle is static, the motor can generate enough heat to meet the heat requirement of the vehicle.

    本发明公开了一种用于车辆的电机主动发热控制方法和系统及车辆,涉及车辆技术领域。用于车辆的电机主动发热控制方法包括判断车辆是否有热量需求;检测车辆的运行状态;若车辆有热量需求且处于静止状态,控制电机的直轴电流为直流电流,同时控制电机的交轴电流为零;其中,电机的直轴电流为直流电流且电机的交轴电流为零时,电机的内部形成与电机的转子磁场平行的恒定磁场,电机无扭矩输出。本发明还提供了相应的控制系统。同时,本发明还提供了一种车辆,采用上述的控制方法来控制电机发热或包含上述的控制系统。本发明能够在整车静止时使电机产生足够的热量以满足车辆的热量需求。
