摘　　要：汽车总线技术随着汽车行业技术现代化升级也进一步深入汽车设计研究领域,在控制器之间通信交互的应用中更普遍广泛。网络拓扑结构作为总线网络设计最重要的一环,如何合理地将配置的各控制器连接起来实现较高的通信性能,并且尽可能防止网络故障导致的信息流传递故障,这是工程设计人员必须考虑的方面。文章基于电气系统架构及总线拓扑设计原则提出一种提高信息传输安全性的冗余的拓扑设计,对现有应用的设计做出优化方案。Automotive bus technology with the automotive industry technology modernisation and upgrading also further penetrate into the field of automotive design and research,in the application of communication and interaction between controllers is more common and widespread.Network topology as the most important part of the bus network design,how to reasonably connect the configuration of the various controllers to achieve high communication performance,and as far as possible to prevent network failure caused by the information flow transmission failure,which is necessary for engineering designers to consider.This paper proposes a redundant topology design to improve the safety of information transmission based on the electrical system architecture and bus topology design principles,and makes an optimisation plan for the design of existing applications.
