Research And Expoitation On Funtion Test-Bed Of Car LIN Bus Comfort System

With the rapid development of technologies of car network, the car network becomes more and more important in the car electronic system. For thirty years since technologies of car network came forth, car network system have been indispensable for car electronic with the development of semi-conductor and network protocol, and it's not only the way to solve the problem of complicated wiring harness ,but the basic of car information and control system. The car network offers the API and hide the details, which makes developers work in application layer , increases the speed of transform and reduce the wiring harness. As CAN,LIN,UART,VAN, there are lots of car protocol coming out. Among them, LIN gives the whole network technology new energy and shows us a cheap and stabilized protocol. In this background , Faw-Volkswagen use the LIN bus in the car comfort system , and it is a special word in the car ,it mainly control the windows-lifter,locks-closedown,top lighting-control,and baggage trunk.. In order to ensure the stability and reliability of the LIN comfort system in using., We make the project is to research the test-bed of car LIN bus control system,as showed in Figure 1.The purpose of the test-bed is to test windows-lifter,locks-closedown,top lighting-control,and baggage trunk.of the car and the voltage and the speed of the LIN bus.Figure 1. Reality of the test-bed...
