摘　　要：将KEELOQ编解码技术与无线通信技术相结合,设计了一种由车载LF发射模块、钥匙编码模块和车载接收解码模块组成的汽车被动无钥门禁系统.该系统无需人为干预就可自动执行对用户的身份识别,安全方便,且稍加改动即可应用于汽车轮胎测压、车库防盗等方面,具有较强的推广价值.A new type automo KEELOQ technology and the （LF） initiator carried by auto system not only can recognize bile passive keyless entry system is designed by means of combination of the radio-communication technology. This system is composed of low-frequency mobile, transponder taken by driver, PKE receiver carried by automobile. This user identity without keystroke, security and convenience, but also can make up automobile tire pressure monitoring system or garage burglar alarm system ect. So it has stronger extension value.
