The invention relates to a motor driving system, a vehicle and a driving system control method. The driving system comprises a heating controller, a motor controller and a driving motor; the heating controller is configured to generate multiple paths of high-frequency PWM signals when detecting that the vehicle is in a parking state and receiving a heating request, and output the multiple paths of high-frequency PWM signals to the motor controller so as to control the motor controller to output high-frequency alternating current to a stator of the driving motor; the stator and the rotor of the driving motor generate heat in a static state, and the heat is conducted to the device which initiates the heating request. Thus, heat generated when heating is needed in the parking process of an existing motor driving system on the vehicle can be reused to heat a device initiating a heating request, the overall heating capacity and heating efficiency of the vehicle are improved, even additional heating equipment can be omitted, parts of the vehicle are centralized, the size is reduced, and the vehicle cost is reduced.

    本公开涉及一种电机驱动系统、车辆及驱动系统控制方法。驱动系统包括:加热控制器、电机控制器和驱动电机;加热控制器被配置为:在检测到车辆处于驻车状态且接收到加热请求时,生成多路高频PWM信号,并输出多路高频PWM信号至电机控制器,以控制电机控制器输出高频交流电流至驱动电机的定子,以使得驱动电机的定子和转子在静止状态下产生热量,并将热量传导至于发起加热请求的装置。这样,可以复用车辆上现有的电机驱动系统在驻车需要加热时产生热量,以为发起加热请求的装置进行加热,增强车辆整体的加热能力和加热效率,甚至可以取消额外的加热设备,让车辆的零部件集中化,缩小体积,降低车辆成本。
