车载以太网SOME/IP协议及一致性测试系统研究

Research on Conformance Testing System for Protocols in Automotive Ethernet SOME/IP

随着汽车网联化、智能化、电动化的快速发展,车载以太网已成为新型网络架构中的骨干网络。对汽车而言,汽车的自主度越高,系统故障导致的后果也将变得越来越严重,并且国内车载以太网技术处于发展的初期,为保证这些系统安全可靠地运行,车载以太网协议一致性测试显得尤为重要。SOME/IP属于车载以太网架构中应用层和传输层之间的中间件,对于SOME/IP而言,它是面向服务的通信。SOME/IP协议一致性测试包括SOME/IP Server测试及SOME/IPETS测试,测试结果表明,该测试系统能够有效检测出DUT在服务请求及服务应答过程中的错误,为供应商及主机厂完善产品协议规范提供帮助。

With the rapid development of automobile networking,intelligence and electrification,vehicle Ethernet has become the backbone network in the new network architecture.For cars,the higher the autonomy of the car,the more serious the consequences of system failures will become,and the domestic vehicle Ethernet technology is in the early stage of development.To ensure the safe and reliable operation of these systems,it is particularly important to test the consistency of on-board Ethernet protocol.SOME/IP belongs to the middleware between the application layer and the transmission layer in the vehicle Ethernet architecture.For SOME/IP,it is service-oriented communication.SOME/IP protocol conformance test includes SOME/IP Server test and SOME/IP ETS test,and the test results show that,the test system can effectively detect errors of DUT in the process of service request and service response,and provide help for suppliers and OEMs to improve product protocol specifications.
