Abstract
In the modern vehicle systems, most of body electronic features and driver
support functions are realized as cooperating distributed real time tasks on communication
networks. It requires reliable communication networks in order to ensure body system
reliability. OSEK/VDX Network Management (NM) is currently used to enhance the safety
and the reliability of in-vehicle network systems. By use of OSEK-NM, each node can
determine its own participation in the network, and also discern other nodes´ presence in the
network. In order to enhance the reliability of the system, application should monitor
participation and withdrawal of itself and others, and react to this information.
This paper classifies network faults according to design attributes which are provided by
OSEK-COM, OSEK-NM and application. The network fault countermeasure was proposed to
prevent the network faults and system functionality level problems from spreading.
A simplified body system is used to demonstrate the feasibility of these network fault
countermeasures.
