Validation of CAN Nodes Health Monitoring Method

Tomáš Pospíšil, Jirí Novák

Abstract

Controller area network (CAN) is now used in wide range of distributed applications. The quality of communication in such applications is usually an important factor. This paper describes validation of new developed online diagnostic method which aim is to recognize progressively degrading nodes on the CAN bus. The method uses existing network equipment and requires no additional/specialized network nodes. Standard components for CAN bus faults management like node error cou nters are used instead. Validation of diagnostic model compares results of the simulations with the results achieved on actual CAN bus implementation with progressively degrading node.
