摘要： 为实时监控车载网络中的节点，在使用控制器区域网络(CAN)总线的车载网络中，设计并实现一种基于OSEK/VDX规范直接网络管理(NM)的车载NM系统。由车载网关通过CAN总线收集各网络节点的故障信息，通过IPv6无线网络上传至远程故障诊断服务器，并将得到的故障处理信息下发至有关节点，实现车载CAN网络与远程故障诊断服务器的信息交互。测试结果表明，各网络节点上线后能快速建立稳定的逻辑环通信，并为远程故障诊断提供操作平台。

Abstract: In order to monitor the node in in-vehicle network in real time, this paper designs and implements in-vehicle Network Management(NM) system based on OSEK/VDX specification direct NM in in-vehicle network which using Controller Area Network(CAN) bus. The in-vehicle gateway collects information from the fault node, communicates with the remote fault diagnostic service through the IPv6 wireless network, sends the execute information from the service to the node, and implements the information exchange between the fault node and the remote fault diagnostic service. Text results show that network node after on line can quick build stable logical ring communication, and provide operation platform for remote fault diagnosis.
