The invention provides a control method and device of a vehicle driving system and the vehicle driving system.The method comprises the steps that the temperature and power of a traction motor at the current moment are obtained, and the current motor temperature and the current motor power are obtained; and according to the current motor temperature and/or the current motor power, at least adjusting the rotating speeds of the first fan and the second fan so as to cool the generator, the converter and the traction motor at the same time. The purpose of cooling the generator, the converter and the traction motor at the same time is achieved, the heat dissipation efficiency of the vehicle driving system is improved, and therefore the problem that the heat dissipation effect of the vehicle driving system is poor due to the fact that the traction motor is cooled only by installing a draught fan in an existing scheme is solved.
本申请提供了一种车辆驱动系统的控制方法、装置和车辆驱动系统,该方法包括:获取牵引电机在当前时刻的温度和功率,得到当前电机温度和当前电机功率;根据当前电机温度和/或当前电机功率,至少调节第一风机和第二风机的转速,以同时对发电机、变流器和牵引电机进行降温。达到同时对发电机、变流器和牵引电机进行降温的目的,提高了车辆驱动系统的散热效率,从而解决了现有方案仅仅是通过安装风机对牵引电机进行降温,从而导致车辆的驱动系统的散热效果较差的问题。
