The invention relates to the technical field of vehicle fault detection, particularly provides a vehicle fault detection method, device and system, a server and a medium, which aim to solve the technical problem that the existing vehicle cannot detect a sleep fault in time, so that the power supply of the vehicle is insufficient, and the starting of the vehicle fails. For the purpose, according to the method of the embodiment of the invention, in response to a received fault analysis request, charge state change information of a vehicle low-voltage battery in the fault analysis request can be obtained; whether the low-voltage battery of the vehicle is in an over-discharge state is analyzed according to the charge state change information; if yes, the vehicle is judged to have a sleep fault; the fault analysis request is request information output after the vehicle equipment executes the vehicle locking operation and detects that a high-voltage power supply system of the vehicle is powered off. Through the above steps, whether the vehicle has the sleep fault can be detected in time, so that maintenance personnel and users can take corresponding measures in time, and vehicle starting failure caused by insufficient power supply is avoided.

    本发明涉及车辆故障检测技术领域,具体提供了一种车辆故障的检测方法、装置、系统、服务器及介质,旨在解决现有的车辆无法及时检测休眠故障而使车辆供电不足,导致车辆启动失败的技术问题。为此目的,根据本发明实施例的方法,可以响应于接收到的故障分析请求,获取故障分析请求中车辆低压电池的荷电状态变化信息;根据荷电状态变化信息,分析车辆低压电池是否处于过放状态;若是,则判定车辆发生休眠故障;其中,故障分析请求是车辆设备在执行完锁车操作且检测到车辆的高压供电系统下电后输出的请求信息。通过上述步骤,可以及时检测出车辆是否发生休眠故障,以便于维修人员和用户及时采取相应措施,避免因供电不足而导致车辆启动失败。
