Abstract:

Integrated vehicle health management (IVHM) technology has been widely accepted and adopted due to its outstanding performances in vehicle safety and reduction in aviation cost. From an overview of IVHM′s development history, function, data flow, system constitution and architecture aspects, this paper gives a thorough introduction of IVHM issues, definition and important technique elements. Through a comprehensive analysis for the key technique and difficulties involved in developing IVHM, some feasible approaches are given, and the developable direction and content of IVHM technologies are also made clear.
