车载网关功能设计与测试浅析

Design and Test Method of Central Gateway

本文从车载总线网络架构演进,通过对当前车载网络需求的辩证分析,阐述一种车载网关的设计方法。该方法可以保证中央网关协议转换、流量控制和网络管理等功能设计的实现,还可以满足整车网络信息交互的实时性和可靠性要求,最后给出一种适用于车载网关自动化验证测试的方法。

Based on the evolution of vehicle network,this paper describes a design method of vehicle gateway,through the dialectical analysis of current vehicle network requirements.This method can ensure the realization of central gateway protocol conversion,flow control and network management function design,and can also meet the requirements of real-time and reliability of vehicle network information interaction.Finally,an automatic verification test method is given for gateway test.
