摘要

Diagnosis of automobile system faults is a vital activity in their maintenance. It is a highly skilled activity that consumes time and effort. The variation of system parameters indicates the faults and to assimilate these, the understanding of system structure is essential. In this paper, the automobile system structure is modeled for fault diagnosis using the digraph approach. A system digraph is generated that shows the relationships between the system input and output parameters in conditions of normal working and failure. The diagnosis tree of a failure or symptom is accessed from the digraph model, which includes failure contributing events. The methodology is narrated through an example of the development of a diagnosis tree for clutch system failures. The methodology helped in assimilating the relationship among various input and output parameters of the clutch system and understands the failure path. The suggested methodology helps garage professionals for quick and error-free diagnosis of faults. Moreover, this can guide designers in the reliability-based design and the development of reliable automobile systems.
