摘　　要：为了满足汽车电子电路和安全问题的严格化要求,可采用电子监控诊断方法来监控继电器开关触点。本文讲述通过继电器内部的触点系统的桥接方式和线圈系统的动态性能的变化对触点的电阻变化进行判断的诊断方法。此种采用电子监控的方式来监控线圈驱动器的继电器诊断方法,可及时提供电路状态信息,提高了汽车电路的安全性。To meet the stringent requirements of automotive electronic circuits and security issues, diagnostic methods can be used to monitor electronic monitoring relay switch contacts. This article describes changes in the dynamic performance of the relay contacts inside the system by bridging mode and coil system for the diagnosis of contact resistance variation method to determine the conduct. This by way of the electronic monitoring device to monitor a relay coil driver diagnostic method, the status of the circuit to provide timely information to improve the safety of the vehicle circuit
