Fault detection method for high-voltage power-on of vehicle and vehicle

The invention relates to a vehicle high-voltage power-on fault detection method and a vehicle. According to the vehicle high-voltage power-on fault detection method, whole vehicle detection, power battery detection, accessory detection, motor detection and brake system detection are carried out on a vehicle in sequence, and a first detection result, a second detection result, a third detection result, a fourth detection result, a fifth detection result and a sixth detection result are output respectively. And judging whether the high-voltage system is powered on or not according to each detection result. The fault detection method for the high-voltage power-on of the vehicle comprises six detection steps according to the working sequence of the high-voltage power-on of the vehicle, and the whole vehicle is completely detected once. The detection method is diversified, the detection parts are comprehensive, and the fault position can be accurately and quickly positioned. 本申请涉及一种车辆高压上电的故障检测方法及车辆。本申请提出的车辆高压上电的故障
