摘要
LIN(LocalInterconnectNetwork)协议是面向车辆低端分布式应用的一类多路复用串行通信协议。符合SAE(SocietyofAutomobileEngineering)规定的车用网络通信A类标准。该协议基于通用的UART/SCI硬件接口,采用改进的ISO9141单线传输标准,采取单主多从的总线型拓扑结构并提供方便的用户应用编程接口。LIN最初设计目标作为CAN(ControllerAreaNetwork)的下层网络,同CAN相结合可构成车辆应用中的分层网络结构。对该协议进行了较为详细的描述,并以车门系统为例给出了LIN在车身控制中的应用。
The LIN(Local Interconnect Network)is a multiplex serial communication protocol intended to be used for distributed electronic systems in v ehicles which accords with class -A c ommunication standard defined by SA E(Society of Automobile Engineering).Based on common UART /SCI interface hardware and ISO 9141standard for single line driver /receiver with so me enhancements,LIN supports the bus -type topology with single -master/multiple -slave and provides conven ient API for user to develop their application.LIN originally aims to be a lower protocol of CAN(Controller Area Network)and can be used to shape hierarchical network with it.This paper de-scribes LIN protocol in details and p rovides a sample of body control of Au tomobile.
