摘要
CAN总线是车载网络系统中的重要组成部分,目前已在汽车动力系统和车身系统中得到广泛应用。随着汽车电子化技术的不断深入发展,汽车上电子控制单元(ECU)的数量已经越来越多,而一些高端汽车电子控制单元数量已达到几十个,传统的集中式网络架构由于负载率等问题已难以满足需求。本文提出的分布式网络架构可以弥补传统网络架构在负载率、安全性上的不足。
CAN BUS is an important consist of vehicle network. It has been applied to power system and body system of vehicle widely.With the development of vehicle electronic, the number of ECU increased rapidly, even more than 30 in some high-end vehicle. Traditional centralized network architecture could not accord with the demand owing to the limitation of Busload. Distributed architecture provided in this article can make up the vice of Busload and security.
