Vehicle health monitoring for AVCS malfunction management

Abstract

Vehicle health monitoring as related to malfunction management is discussed. The needs and the functions for vehicle inspection, performance monitoring and failure detection/diagnosis are addressed. The safety critical functions of an Advanced Vehicle Control System (AVCS) and the major functions using failure mode effects and critically analysis are identified. The requirements for a monitoring system regarding detection time, fail-safe characteristics and self diagnosis capability for monitoring devices are examined. Potential monitoring techniques are investigated. It is concluded that health monitoring is a vitally important function for a safety-critical system of components.
