The invention provides an abnormal wake-up fault diagnosis method and system for a vehicle. The method comprises the steps that when the vehicle is in a sleep state, whether an abnormal wake-up fault exists in an electronic and electrical system of the vehicle or not is determined based on a light detection signal from at least one light sensing device, and the at least one light sensing device is arranged in a cabin of the vehicle and is configured to detect light in the cabin; obtaining fault information in response to the abnormal wake-up fault of the electronic and electrical system; and sending the fault information through the vehicle-mounted networking equipment of the vehicle to carry out fault diagnosis. According to the scheme, the abnormal wake-up fault possibly existing in the electronic and electrical system can be diagnosed when the vehicle sleeps, the situation that the vehicle cannot be started due to the fact that the storage battery of the vehicle is exhausted is avoided, and meanwhile the service life of the storage battery is prolonged. In addition, according to the scheme, fault information can be recorded for subsequent diagnosis, maintenance or updating of the electronic and electrical system, the cost is low, implementation is easy, and the user experience is improved.

    本发明提供了一种车辆的异常唤醒故障诊断方法和系统。该方法包括:在车辆处于睡眠状态下,基于来自至少一个光传感设备的光检测信号,确定车辆的电子电气系统是否存在异常唤醒故障,至少一个光传感设备设置在车辆的座舱内并且被配置为检测座舱内的亮光;响应于电子电气系统存在异常唤醒故障,获取故障信息;经由车辆的车载联网设备发送故障信息以进行故障诊断。通过本发明的方案,可以在车辆睡眠时诊断出电子电气系统可能存在的异常唤醒故障,避免车辆的蓄电池被耗尽而导致车辆无法启动,同时延长了蓄电池的寿命。此外,本发明的方案还能记录故障信息以用于后续对电子电气系统的诊断、维护或更新,成本低廉且易于实现,提高了用户体验。
