中文摘要：

考虑到传统被动无钥匙进入系统是一个孤立的系统,存在诸多安全隐患,无法整合到车联网和车身控制系统,设计一种基于CAN总线和互联网的被动无钥匙进入系统。通过CAN总线与车身控制系统无缝结合,使控制更加标准,可拓展实现胎压监测、一键启动等功能。通过互联网远程控制汽车,采用安全协议传输数据,使系统更加方便安全。给出系统软硬件设计,在奔腾B70上进行实车测试,测试结果表明了该系统的有效性、安全性、易用性和可扩展性。

英文摘要：

Considering that traditional passive keyless entry system is an isolated system which causes many security risks,and can neither be integrated into the Internet of vehicles nor body control systems,apassive keyless entry system based on CAN bus and Internet was designed.Seamless combination of CAN bus and body control systems,made the system not only more standard to control,but also more scalable to achieve abundant functions,e.g.,automotive tire pressure monitoring and keyless ignition.Employment of the Internet in vehicle remote control,on which data were transmitted through a secure protocol,made the system more convenient and secure.Hardware and software design of the system was given,and tests with Besturn B70 were carried out.Experimental results show the effectiveness,security,availability and scalability of the system.
