Design and Test of Gateway Communication for a Passenger Vehicle

随着汽车电子技术的发展,车上的电子系统越来越多,需要共享并相互传递大量的信息,传统的布线已不能满足要求,汽车总线技术成了解决这些的关键技术.整车网络结构越来越复杂,为了保证整车网络的正常运行,网关作为“桥梁”产生并大量应用.本文介绍了网关的通信设计,包含路由模式,信号路由,路由策略等,并在某车上进行了应用,最终通过仿真、测试验证了该网关通信设计的正确性.

With the development of automotive electronic technology,more and more electronic systems are adopted in cars.Electronic systems need to share and transmit large amounts of information.Traditional cabling is no longer able to meet the requirements.Bus technology has become the key technology to solve the problem.The network structure of the whole vehicle is becoming more and more complex.In order to ensure the normal operation of the whole vehicle network,the gateway is used as a"bridge".This paper introduces the design of gateway communication,including routing mode,signal routing,routing strategy and so on.It is applied in a vehicle,and the correctness of design is verified by simulation and test.
