基于SOME/IP的整车电气通信网络设计研究

EE Communication Network Design and Research Based on SOME/IP

汽车功能的发展依赖于汽车电子数据处理和传输能力的升级。数据传输能力升级的主要方式包括通过提升现有车载通讯速率。当前满足车载环境的以太网技术逐渐被应用,部分车厂已经有车载以太网应用的量产车型,以太网速度也逐渐从100 Mbps提升到1000 Mbps,车载以太网已经走向大规模应用。SOME/IP(Scalable service-Oriented MiddlewarE over IP)协议是基于车载以太网的通信接口,与当前汽车总线CAN面向信号的通信方式有很大不同,所以整车厂在应用车载以太网作为通信媒介设计电气通信网络架构时会出现很多问题,甚至是无法合理应用与开发。面向服务的通信方式是SOME/IP的关键特性和优势,如何有效与正确应用是基于车载以太网设计电气通信网络的关键,提供基于SOME/IP的整车电子电气通信网络设计方法。

Vehicle EE function upgrading depends on the development of the electronic data processing and data transmission.The major approaches of data transmission capacity upgrading include the frequency of existing vehicle communication protocol through ascension and more rapid communication method vehicle applications.The current Ethernet is applied gradually meet the environmental requirements for vehicle,some OEMs have vehicle products with Ethernet technologies ready to be launched on market,Ethernet speed is also gradually increased from 100 Mbps to 1000 Mbps,Ethernet technology has large-scale application.SOME/IP(Scalable service-Oriented MiddlewarE over IP)protocol is based on the on-board Ethernet communication interface,and the signal oriented communication mode for vehicle CAN BUS is different,so many problems will appear when OEMs have on-board Ethernet in vehicle application as the electric communication network architecture for the communication media design.Service-oriented communication mode is the key feature and advantage of SOME/IP,how to effectively and correctly implement the application is the key to design electrical communication network based on vehicle on-board Ethernet,this paper is to provide the design method of electronic and electrical communication network for whole vehicle based on SOME/IP.
