Abstract
Aiming at the potential safety hazard of the car on⁃board diagnostic(OBD)interface,a vehicle⁃mounted informa⁃tion safety repeater was designed,which takes i.MX6 series processor as the core,and uses the MCP2515 CAN controller to ac⁃cess into CAN bus through its serial peripheral interface. On the basis of analyzing the working principle of the Linux device driver,the driver design method of CAN interface under Linux system is expounded. The drive of CAN interface under Linux system was implemented,and the relaying problem of vehicle⁃mounted CAN bus was solved. The iso15031 protocol filter is added into Linux system to filter the illegal instructions,and provide a protective screening for transmitting the vehicle⁃mounted infor⁃mation through CAN bus.关键词
