The invention relates to the technical field of new energy vehicles, in particular to a low-voltage interlocking self-checking loop, a self-checking method and a vehicle, and the low-voltage interlocking self-checking loop comprises a female end plug-in, a male end plug-in, a detection assembly and a control assembly. The female end plug-in and the male end plug-in are plugged to form a closed loop, and the detection assembly is used for detecting whether the closed loop meets a preset open circuit condition or not; and when the detection assembly detects that the closed loop meets a preset open circuit condition, the control assembly controls the female-end plug-in and the male-end plug-in to be separated to form an open circuit. Therefore, the problems that the workload of troubleshooting the wiring harness problem is large, the project development progress is delayed and the like are solved, and the fault position caused by loosening and disconnection of the connector is rapidly judged and identified, so that the troubleshooting efficiency is improved, and the automobile troubleshooting time is saved.

    本申请涉及新能源汽车技术领域,特别涉及一种低压互锁自检回路、自检方法及车辆,包括:母端插件、公端插件、检测组件和控制组件。母端插件和公端插件对插后形成闭合回路,检测组件用于检测闭合回路是否满足预设的断路条件;控制组件在检测组件检测到闭合回路满足预设的断路条件时,控制母端插件和公端插件脱开形成断路。由此,解决了线束问题排查工作量大、拖延项目开发进度等问题,快速判断快速识别由于接插件松动、断开引起的故障位置,从而提高故障排查效率,节约汽车故障排查时间。
