Abstract: With the continuous improvement of society and scientific and technological level, a new vehicle configuration, vehicle keyless detection system PEPS, has been derived. With the emergence of PEPS, it has completely changed the application prospect of automobile security and brought users a new comfortable and convenient experience. This paper introduces the composition and control principle of PEPS on Roewe 950 car, analyzes and eliminates the failure of keyless entry, analyzes the causes of the failure, and helps the maintenance personnel have a deeper understanding of the maintenance of PEPS system.
Key Words: PEPS; Keyless entry; Fault diagnosis and maintenance; Troubleshooting
随着科技的进步,现代轿车大多采用一键启动方式,没有了传统轿车的点火开关。一键启动系统轿车都采用了车辆无钥匙进入系统,该文以荣威950轿车为例,介绍无钥匙进入系统PEPS的典型故障诊断与维修方法。
1 PEPS的组成
PEPS系统的组成部件有:遥控钥匙、车门外把手天线及开关(HSU)、三个内部低频电线、后部保险杠低频天线、一键起动按钮(SSB)、备用线圈、LIN线和CAN线、PEPS模塊和BCM模块。
每辆车配有两把匹配的遥控钥匙。车门外把手天线及开关(HSU)安装于前车门外把手的内部。三个内部低频电线分别安装于空调箱总成、中控台安装支架后部和后排座椅安装横梁的中心线上。后部保险杠低频天线位于后保险杠安装支架的中心线上。一键起动按钮(SSB)位于驾驶室仪表板上,用于请求发动机起动和停止的运作。备用线圈集成安装在乘客侧杯托下方。
2 PEPS的控制原理
结合图1分析原理。遥控钥匙在PEPS系统中进行低频、射频通信[1]。只要锂电池有电,遥控钥匙都能接收到低频信号,与BCM实现通信,进行车辆的正常锁止解锁运作。……
