This chapter discusses the methodology for diagnostics or prognostics in a specific vehicle, applicable to any vehicle, hybrid and electric vehicles included. All modern automobiles have onboard diagnostic functions that can give a certain amount of diagnostics, but not prognostics. Recent events reported in the news media regarding faulty vehicles, including hybrid electric vehicles (HEVs), relating to brake failure, have led to significant concerns about the safety and reliability of HEVs. Electromagnetic compatibility is an important issue today, in view of the fact that HEVs and EVs use significant amounts of power electronics which use high‐power, high‐frequency switching. Ito has studied the vibration problem in an HEV engine in reasonable detail. The method suggested to improve the noise vibration harshness (NVH) issue includes opening the exhaust port during the shutdown sequence of the engine. In HEVs and EVs, the end‐of‐life issue is associated with the life of the various components and overall life cycle management.
