The invention discloses a method for judging start and stop of a vehicle by adopting an OBD (On-Board Diagnostic) interface, comprising an acquisition module I and an acquisition module II, the input ends of the acquisition module I and the acquisition module II are respectively connected with an H signal end and an L signal end of the OBD interface, and the output ends of the acquisition module I and the acquisition module II are connected with an operation module; when the method is adopted to judge the start and stop of the vehicle, the judgment information of the start and stop of the vehicle can be realized only through very simple voltage acquisition, the method is very reliable, communication in a data exchange mode with the vehicle is not needed, and the method is simple and convenient to operate. The data interference hidden danger is completely eradicated, the cost can be effectively controlled and managed, and the reliability is improved.

    本发明公开了一种采用OBD接口判断车辆启停的方法,包括采集模块一和采集模块二,所述采集模块一和采集模块二的输入端分别与OBD接口的H信号端和L信号端连接,所述采集模块一和采集模块二的输出端与运算模块连接,运算模块输出端连接有比较模块,比较模块与微处理器连接,采用本发明的方法对车辆的启停进行判断,只需要很简单的电压采集就能实现车辆启动和停止的判断信息,而且非常可靠,无需与车辆产生数据互换的方式进行通讯,杜绝数据干扰隐患,可以有效的控制和管理成本,同时提高可靠性。
