摘要
针对整车网络节点的诊断问题,设计了基于独立网关的UDS服务。分析了网关的硬件电路和软件程序设计方案,使网关的诊断模块实现了报文路由、报文映射、下线检测和Bootloader等功能。搭建了测试环境,编写了诊断数据库,使用CANoe.Diva软件进行自动化测试,结果表明测试项全部通过,达到了设计要求。
Aiming at the diagnosis problem of vehicle network nodes,UDS service based on independent gateway is designed.The hardware circuit and software program design of the gateway are analyzed,and the diagnostic module of the gateway implements functions such as packet routing,message mapping,offline detection and Bootloader.A test environment was set up,a diagnostic database was written,and the CANoe.Diva software was used for automated testing.The results showed that all the test items passed and met the design requirements.
