摘　　要：LIN总线作为汽车电子中常见的一种总线协议,因其通用性广、成本低廉受到众厂商的青睐。为了将LIN总线应用到汽车照明系统上,对LIN报文帧进行了详细的研究,对各个字节的内容进行详细的解释。随后在通用串口的基础上,设计了一套基于LIN总线的汽车照明系统,并给出了主从节点不同的硬件电路图和软件流程图。最终完成了整个照明系统的开发要求。LIN bus, as a bus protocol commonly used in automotive electronics, is favored by most manufacturers, because of its wide versatility and low cost. In order to apply LIN bus to automotive lighting system, this paper studies in detail the LIN message frame, and gives an elaborately explanation of the contents of each byte. On the basis of the general-purpose serial port, the paper introduces a design of a set of automotive lighting systems based on the LIN bus, and gives the master and slave nodes of different hardware schematics and software flow chart.
