摘　　要：针对OSEK直接网络管理(NM)节点状态转换冗余问题,在研究OSEK NM标准的基础上,提出一种改进的OSEK NM状态转换方法,通过剔除合并冗余节点状态,从而有效减少系统初始化反应时间,设计了网络管理协议数据单元到CAN数据帧的映射结构,给出了网络管理设计实现方法,并在汽车CAN系统上实现了OSEK网络管理,最后在CANoe上进行系统仿真,验证了本系统的可行性。To solve the redundant problem of node states transition in OSEK direct network management,an improved method of states transition was proposed based on the OSEK NM standard.The reaction time of system initialization was reduced effectively by eliminating and merging redundant node states.Then the structure of the network management protocol data unit mapping to the CAN data frame was designed,the design method of network management was given and the OSEK network management was implemented in the automotive CAN systems.Finally,the system is verified feasible by simulation on the CANoe.
