汽车网络分类方法及其主流协议发展趋势

Classification Method of Networks in Automotive and Developing Trend of Corresponding Main Protocols

网络技术大大促进了汽车电子技术的发展 ,但随之带来了网络协议的标准化问题 .为此 ,在SAE(societyauto motiveengineering)对汽车网络分类方法进行分析的基础上 ,结合汽车网络技术的最新发展 ,提出了一种根据功能和传输速率将车用网络分为 5类的分类方法 ;并根据此分类方法综述了目前各类网络中主要的通信协议 ,指出其中最具竞争力的协议 。

Automotive electronics is greatly improved by network technology,but standardization of network protocols is a big problem.Based on the analysis automotive network classification method of society automotive engineering(SAE),a new classification method of up to 5 classes is proposed.According to the new classification,corresponding main protocols of these network types are summarized and the most competitive candidates and the network technology developing trend are pointed out.
