摘　　要：为确保汽车通信构架FlexRay的高效实时运行,需要尽可能地简化网络结构设计、降低通信复杂程度,良好的车载网络管理能够实现这些功能。简述了FlexRay通信协议和数据帧结构,在对比两种网络管理机制之后,提出了一种基于新规范的FlexRay网络管理方法。以其基本规范为依据,对网络管理数据的调度进行了分类,设计了数据的动态调度策略。研究表明,该调度策略满足了车载网络的动态性。In order to make FlexRay, the automotive communication framework, work high efficient and in real-time, it is necessary to simplify the network architecture, and reduce the complexity of communication, excellent vehicle network management is able to realize all of these. The communication protocol of FlexRay and structure of data frame are described in brief. On the basis of comparison between two of the network management mechanisms, the FlexRay network management method based on new specification is proposed. In accordance with the basic specification, the data scheduling for network management is classified, and dynamic data scheduling strategy is designed. The research indicates that this scheduling strategy meets the dynamic characteristics of vehicle network.
