Abstract
Field Bus is the network of field intelligent device appeared in the 80's-90's in the world, and also a kind of open and digital serial communication network, which has become one of the most active industrial data buses. As a kind of the Field Bus, CAN（Controller Area Network）Field Bus has high communication speed, good reliability, real-timing and flexibility, and can be easy to interconnect, whose using is expanding to more and more different areas.
With the rapid development of electronic technology and extensive application, and automotive electronics, intelligence and network of Hyundai Motor is the inevitable trend of development. According to a new truck unit of R & D, research and construction of the CAN / LIN bus truck electrical system network. After briefly introducing the electrical system components and functions of the network, the analysis of the CAN / LIN bus characteristics, and in accordance with the actual demand for trucks developed a corresponding application protocol, Finally, the network system software and hardware design specific programmes. Practical applications and test results indicate that this system has good reliability and stability.
