【摘要】 为了检验轿车LIN总线舒适系统的预期功能,研究开发了一套轿车LIN总线舒适系统功能测试台。从LIN总线的实现原理及舒适系统的组成结构入手确定了系统的测试内容;根据测试的内容确定了软硬件的选择,并进行了测控系统的整体结构设计和连接,完成了测试台的搭建和调试;最后按照所要测试的步骤编写了上下位机软件。本测试台顺利完成了对LIN总线舒适系统的检测,给出了测试台实际运行效果的界面、顶灯和升降电机电流数据表、总线上的电压和数据传输速度、LIN总线舒适系统功能检测结果以及可靠性试验数据。综合测定了LIN总线舒适系统的性能,为其投产使用提供了可靠的实验依据,获得了比较满意的检测效果。更多还原

【Abstract】 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.
