The invention relates to the technical field of fault diagnosis, particularly provides a vehicle-mounted sensor fault diagnosis method and device, a medium and a vehicle, and aims at solving the technical problems that in vehicle-mounted sensor fault diagnosis, the fault phenomenon disappears due to disassembly, and the fault diagnosis efficiency is low. In order to achieve the purpose, the vehicle-mounted sensor fault diagnosis method comprises the steps that a domain controller obtains power supply state information of a vehicle-mounted sensor, the condition of a power supply line of the vehicle-mounted sensor is preliminarily judged through the power supply state information, and a further detection mode is obtained. According to the method, a domain controller of a vehicle supplies power to a vehicle-mounted sensor such as a vehicle-mounted camera through a power supply line, obtains the power supply state of the vehicle-mounted sensor, analyzes the power supply state to obtain the preliminary diagnosis state of the power supply line of the vehicle-mounted sensor, and provides a further detection mode for after-sales or research and development personnel to perform efficient targeted inspection. Therefore, the fault reason is obtained.

    本发明涉及故障诊断技术领域,具体提供一种车载传感器故障诊断方法、设备、介质及车辆,旨在解决车载传感器故障诊断中因拆卸导致的故障现象消失以及故障诊断效率不高的技术问题。为此目的,本发明的车载传感器故障诊断方法包括域控制器获取车载传感器的供电状态信息,通过供电状态信息初步判断车载传感器的供电线路的状况并得出进一步的检测方式。该方法中车辆的域控制器通过供电线路为车载传感器例如车载摄像头供电,同时获取车载传感器的供电状态据此分析得出车载传感器的供电线路的初步诊断状态,并提供进一步的检测方式供售后或者研发人员做高效的针对性检验,从而得出故障原因。
