Abstract: With the in-depth development of the new "four modernizations" of automobiles, electronic and electrical systems are becoming more and more complex, and the innovation and expansion of electronic and electrical architecture is imperative. Service-oriented architecture (SOA), model based design (MBD), AutoSAR and Ethernet have become trends for development of the electronic and electrical architecture. The article describes how to realize the developing contents based on the PREEvision software for the service-oriented architecture design. The contents included service and service interface, software architecture, network topology, service deployment, Ethernet protocols, Ethernet SoAD module and SOMEIP serializer, etc. The ARXML files should be produced after building the module. The development process met the technical requirement of the MBD and AutoSAR. It promoted the realization of software-defined vehicles and formed and improved new electronic and electrical architecture platforms.

Key words: Service-oriented architecture (SOA); PREEvision; Model based design(MBD); Auto SAR; SOMEIP; Ethernet

摘要： 随着汽车新“四化”的深入发展，电子电气系统越来越复杂，电子电气架构革新和拓 展势在必行。汽车面向服务的架构（SOA）、基于模型的开发方式（MBD）、AutoSAR 和以太 网等已成为电子电气架构的发展趋势。文章通过阐述基于 PREEvision 工具实现服务及接口定 义、软件架构、网络拓扑、服务部署、以太网通讯、以太网 SoAd 模块和 SOMEIP 序列化等 设计，实现面向服务的架构开发，通过建模之后导出 ARXML 文件完成输出。开发过程符合 模型的开发方式和 AutoSAR 的技术要求。促进了软件定义汽车的实现，形成并完善了新的电 子电气架构平台。
