| Summary: | 碩士 === 國立臺灣海洋大學 === 機械與機電工程學系 === 97 === The Hybrid Electric Vehicle (HEV) developed on environmental consciousness has attracted extensive attention from researchers of related fields in recent years. The objective of this study is to provide a new reliability allocation model and method which allows partial malfunctions of the power system without stalling the vehicle. This reliability design strategy will provide HEV developer a better alternative to design and produce new products with much lower cost and better competitiveness.
In this study, the fuzzy theory, hybrid technology, and the reliability engineering are integrated, and the related reliability information and feasible cost function of HEV were applied to develop a new reliability allocation method in order to achieve fuzzy resolution. It has been shown that this method can reduce the cost and allow the system to tolerate some malfunctions of subsystems under the targeted system reliability. Furthermore, this study provides some reliability-related suggestions for the hybrid power system.
