The invention provides a high-voltage-off fault diagnosis method and device, a vehicle and a storage medium, and belongs to the technical field of intelligent vehicles, and the method comprises the steps: carrying out the communication self-inspection and vehicle control unit self-inspection of the vehicle when a high-voltage-off fault occurs in the vehicle; when the communication self-inspection is normal and the self-inspection of the vehicle control unit is normal, fault diagnosis is carried out on the vehicle high-voltage related parts in sequence according to a preset priority sequence, and the vehicle parts with high-voltage faults are positioned; and giving a fault feedback suggestion based on the fault type of the vehicle component. According to the method, the influence of a vehicle communication system and a controller on the high-voltage failure can be effectively eliminated, vehicle parts with the high-voltage failure can be accurately positioned, the high-voltage failure diagnosis efficiency and accuracy are improved, meanwhile, fault feedback suggestions are given based on the fault type, and maintenance personnel can conveniently process the high-voltage failure.

    本发明提供了一种掉高压故障诊断方法、装置、车辆及存储介质,属于智慧车辆技术领域,其方法包括:当车辆出现掉高压故障时,对车辆进行通信自检和整车控制器自检;当通信自检正常且整车控制器自检正常时,按照预设的优先级顺序,依次对车辆高压关联部件进行故障诊断,定位出现掉高压故障的车辆部件;基于所述车辆部件的故障类型,给出故障反馈意见。本发明能够有效排除车辆通信系统和控制器对掉高压故障的影响,并能够准确定位出现掉高压故障的车辆部件,提高掉高压故障诊断效率和准确性,同时基于故障类型,给出故障反馈意见,便于维修人员对掉高压故障进行处理。
