The invention relates to the technical field of vehicles, in particular to a motor auxiliary heating method and device for a vehicle, and the method comprises the steps: detecting the current cabin temperature of the vehicle and the actual battery pack temperature of a power battery; when it is detected that the actual battery pack temperature is within the first preset range and the current cabin temperature is within the second preset range, whether the vehicle is in a driving mode or not is judged; under the condition that the vehicle is in the driving mode, the vehicle is controlled to enter a motor auxiliary heating mode, and a water pump of the driving motor is started to heat the driving motor. Therefore, the problems that the vehicle cannot control the auxiliary heating function of the motor in real time, the real-time performance of auxiliary heating of the motor is reduced, the utilization efficiency of waste heat of the motor is reduced and the use requirement of the vehicle cannot be met due to the fact that the auxiliary heating function of the motor is controlled to be started or stopped when the vehicle meets a certain condition in the related technology are solved.

    本申请涉及车辆技术领域,特别涉及一种车辆的电机辅助加热方法及装置,其中,方法包括:检测车辆的当前座舱温度和动力电池的实际电池包温度;在检测到实际电池包温度处于第一预设范围,且当前座舱温度处于第二预设范围的情况下,判断车辆是否处于行车模式;在车辆处于行车模式的情况下,控制车辆进入电机辅助加热模式,开启驱动电机的水泵以为驱动电机加热。由此,解决了相关技术中通过车辆满足一定条件进行控制电机辅助加热功能的开启或者关闭,导致车辆无法实时控制电机辅助加热功能,降低电机辅助加热的实时性,并且降低电机废热的利用效率,无法满足车辆的使用需求的问题。
