基于AUTOSAR的LIN实现

摘要

Based on Automotive Open System Architecture(AUTOSAR) specification architecture, by considering Stratified and sub-module, this paper designs Local Interconnect Network(LIN) bus, and describes the realization of LIN driver, LIN interface, protocol data unit router, communication, diagnose communication manager modules. Practice shows that the LIN bus realization based on AUTOSAR specification has better performance on migration, run speed and stability.%汽车开放系统架构(AUTOSAR)标准可简化汽车应用软件的开发流程,使软件有更好的可移植性和可扩展性.为此,采用分层、分模块的思想设计局部互联网络(LIN)总线,给出LIN驱动、LIN接口、协议数据单元路由、通信、诊断通信管理等相关模块的实现方法.实践结果表明,该总线有较好的重用性、较快的运行速度及较高的稳定性.
