The invention relates to a vehicle motor controller cooling method and device, a vehicle and a storage medium, and the method comprises the steps: collecting the actual temperature of at least one electronic device, which can emit heat during operation, of a motor controller, and judging whether the actual temperature is within a safe temperature interval corresponding to each electronic device or not; if the actual temperature of any electronic device is not within the corresponding safe temperature interval, it is judged that the temperature of the motor controller is abnormal, and a temperature cooling instruction of the motor controller is generated; the instruction is sent to the motor controller, so that the DC/DC module of the motor controller supplies power to the vehicle-mounted air conditioner, and the vehicle-mounted air conditioner is used for cooling the motor controller, so that the temperature of each part in the motor controller is monitored in real time, and the temperature in the cavity of the motor controller is accurately controlled by the vehicle air conditioner and the DC/DC module; the failure rate of the device is effectively controlled, the ablation problem caused by overhigh local temperature is avoided, and the cooling effect of the motor controller is improved.

    本申请涉及一种车辆电机控制器冷却方法、装置、车辆及存储介质,其中,方法包括:采集电机控制器的至少一个在运行时会发热的电子器件的实际温度,判断实际温度是否处于对应于每个电子器件的安全温度区间内;如果任一电子器件的实际温度不在对应的安全温度区间内时,则判定电机控制器存在温度异常,生成电机控制器的温度冷却指令;发送该指令至电机控制器,使得电机控制器的DC/DC模块对车载空调供电,以利用车载空调对电机控制器进行降温,从而实时监控电机控制器内各零部件温度,利用整车空调及DC/DC模块对电机控制器腔体内的温度进行精准控制,有效控制器件的失效率,避免出现局部温度过高而造成的烧蚀问题,提高电机控制器冷却效果。
