Diagnosis in Automotive Systems : A Survey

Modern automotive electronic control systems are distributed, networked embedded systems. Diagnostic routines implemented on individual components cannot adequately identify the true cause of anomalous behavior because their view is restricted to component-local information. A growing trend in diagnostics research for these systems is to use system-level approaches to diagnose anomalous behavior and provide a consistent, global view of the system’s health. Current approaches are typically motivated by a desire to improve either off-line maintenance or run-time safety. Acknowledgements: This research was supported in part by General Motors Company.
