| With the development of the modern automobile, the electronic devices of automobile increase rapidly, which brings about the problem that it is necessary for varies of control systems to exchange the signals in the real-time. The traditional wiring hardly can not satisfy this developmental quest, people turn to the automobile LAN.This paper starts from the vehicle LAN, mainly studied the development of the CAN-bus used in advanced automobiles in the world. Researched and absorbed the CAN-bus which is most wide applied in international car industry now. This study of CAN-bus in controlling system of car light, a series of reliable protocol was established. We can transfer all the data only by using a couple wires, which simplifying the wiring harness, improving the reliability, effectively save the fixing space and the system cost.The study of this paper is the helpful explore to independently develop the CAN-bus of our country, it has the meaning to guide the development of the communication of automobile in our country. |
