Abstract： Aiming at the traditional panel with lower precision， less information and bad capability of expand， the CANBus and SAE J1939 protocol were analyzed. The definitions of physical layer and the message format of data link layer were discussed. The structure and realization of protocol J1939 were researched and  applied in vehicle integrated information display system In the process of design， the net nodes were definited， the vehicle information database was  found， the dummy panel and program were edited to simulate some function of vehicle， fournode vehicle information display system was set up with the software of CANoe The results indicate that this system can offer the driver status messages of vehicle assemblies and environment information on the road when the vehicle working， which can make the driver control the vehicle effectively
Key words： CAN technology; car door control system; CAN protocol; J1939
