The invention discloses a high-voltage interlocking fault detection method and device and a vehicle. The method comprises the steps that a high-voltage interlocking fault table is generated according to the connection relation between multiple to-be-detected parts and a circuit switching component, and the high-voltage interlocking fault table is used for determining the mapping relation between the multiple to-be-detected parts and multiple fault voltage values of a high-voltage interlocking loop; acquiring a current voltage signal value on the high-voltage interlocking loop; and determining a target fault part from the plurality of to-be-detected parts by using the high-voltage interlocking fault table and the current voltage signal value. The technical problems of low fault detection efficiency and poor safety caused by the fact that a high-voltage interlocking fault detection method provided by the prior art cannot position a fault part are solved.

    本发明公开了一种高压互锁故障检测方法、装置及车辆。其中,该方法包括:根据多个待检测零件与电路转接部件之间的连接关系,生成高压互锁故障表,其中,高压互锁故障表用于确定多个待检测零件与高压互锁回路的多个故障电压值之间的映射关系;获取高压互锁回路上的当前电压信号值;利用高压互锁故障表和当前电压信号值,从多个待检测零件中确定目标故障零件。本发明解决了现有技术提供的高压互锁故障检测方法无法定位故障零件导致故障检测效率低、安全性差的技术问题。
