| 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 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 the international car industry now. This study of CAN-bus in controlling system of automotive Central Door Lock, 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 malfunction causes and inspection of automotive Central Door Lock are analyzed with fault tree, developing the fault tree for example with the malfunction of automotive Central Door Lock. The faults causes and inspection of this system are analyzed with the way of the minimum Fussed.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 and the Vehicles Breakdown Diagnose System in our country. |
