FlexRay网络是新一代车载通信网络。为了保证FlexRay网络的可靠性和安全性,在研究OSEK网络管理规范及FlexRay网络特点的基础上,提出在FlexRay网络通信周期动态段中实现OSEK网络管理的方案,分析了网络管理消息的发送时延,研究了网络管理协议数据单元到FlexRay数据帧的映射结构以及网络管理的具体实现过程。最后在CANoe上进行了仿真实验,验证了本方案的可行性。
F1exRay network is a new generation vehicle communication network.To guarantee the reliability and safety in FlexRay network,a scheme of OSEK network management realized in dynamic segment of FlexRay network communication cycle is proposed on the based of the OSEK network management standard and FlexRay network feature.Then the transmission delay of network management massage is analyzed,and the structure of the network management protocol data unit mapping to the FlexRay data frame and the concrete realization process of network management is re-searched.Finally,the method was verified feasible by simulation on the CANoe.
