车载以太网SOME/IP测试的研究与分析

Research on SOME/IP Protocol Test for Vehicle Ethernet

随着汽车技术的飞速发展,车辆智能化、网联化、电动化快速推进,软件定义汽车成为关键,SOA设计方法引用至汽车软件开发中,车辆诊断、软件刷新、影音娱乐、智能驾驶等功能日益增多,对汽车电子电器的开发提出了新的挑战。为了实现技术整合,满足用户驾驶功能、性能需求,采用基于以太网技术的SOA架构几乎是所有整车厂关注的焦点,而面向服务的通信协议SOME/IP是实现SOA的重要一环。本文基于车载以太网测试工作实践,阐述SOME/IP协议应用需求、通信机制、SOME/IP协议测试及相关实例等,以便为车载以太网测试方面的同仁提供一些参考。

With the rapid development of automotive technology, the direction of vehicle intelligence, telematics and electrification is advancing rapidly. " Software defines vehicle" has become the key. SOA design method is introduced into automotive software development. Vehicle diagnosis, software updating, infotainment, ADAS and other functions are increasing day by day, which brings new challenges to the development of automotive electronics. In order to realize technology integration and meet the driving function and performance requirements of users, the Ethernet technology based SOA architecture has become the focal point of almost all vehicle manufacturers, and the service-oriented communication protocol SOME/IP is an important part of realizing SOA. Based on the practice of vehicle Ethernet testing, this paper elaborates the application requirements of SOME/IP protocol, communication mechanism, SOME/IP protocol testing and related examples so as to provide some references for colleagues in vehicle Ethernet testing.
