The invention provides a fault detection system and a vehicle, the fault detection system comprises a plurality of conversion modules, a plurality of detection modules, a plurality of signal processing modules and a control module, and each conversion module can output a corresponding electric signal based on the connection state of a low-voltage detection connector; the plurality of detection modules receive the electric signals and output corresponding detection signals based on the electric signals; a plurality of signal processing modules receive the detection signals; and the control module receives the detection signals processed by the plurality of signal processing modules, and determines the on-off state of the high-voltage interlocking loop and the connection state of the plurality of low-voltage detection connectors based on the plurality of detection signals. According to the system, the connection state of the low-voltage detection connector can be converted into a high-low level detection signal which can be identified by the control module, so that the control module can accurately know the fault position and the on-off state of the high-voltage interlocking loop based on the detection signal, the detection and troubleshooting efficiency is improved, and the detection reliability is relatively high.

    本申请提供了一种故障检测系统以及车辆,故障检测系统包括多个转换模块、多个检测模块、多个信号处理模块和控制模块,每一转换模块能够基于低压检测接插件的连接状态输出对应的电信号;多个检测模块接收电信号,并基于电信号输出对应的检测信号;多个信号处理模块接收检测信号;控制模块接收来自多个信号处理模块处理后的检测信号,控制模块基于多个检测信号确定高压互锁回路的通断状态以及多个低压检测接插件的连接状态。该系统能够将低压检测接插件的连接状态转化为控制模块可识别的高低电平检测信号,使得控制模块能够基于检测信号精准得知故障位置以及高压互锁回路的通断状态,提高了检测以及排查效率,检测可靠性较高。
