Abstract:

A network management system complied with the specification of OSEK/ VDX direct NM for actual demand of the in-vehicle CAN network is designed and implemented. This system uses the stable logical ring communication as an operation platform, which updates the nodes' configurations and the network states. The system uploads information to the remote fault diagnostic service by in-vehicle gateway through the wireless network and receives command and inquiry message to relative nodes. The mechanism that nodes establish a stable logical ring under the order proposed in this paper was verified by application in relative projects. The system designed in this paper implements the real-time monitoring on the in-vehicle CAN network effectively.

Key words: network managemen, controller area network(CAN), remote fault diagnosis
