汽车无钥匙进入系统区域定位研究

Research on Area Location of Passive Keyless Entry System

对汽车无钥匙进入系统利用125 kHz低频通讯进行钥匙定位的原理分析,在此基础上提出基于四低频发射天线的无钥匙进入系统区域定位方法,并在实车上进行测试。经测试表明,该定位方法可以准确显示钥匙所在区域,满足无钥匙进入系统的要求。

The principle of using 125kHz LF communication to locate the key in Passive Key- less Entry System is analyzed. Furthermore, the area location method based on four LF transmitter an- tennas is analyzed. Through testing in the real vehicle, this method can actually display the key loca- tion and that can meet the requirement of Passive Keyless Entry System.
