本論文研究車輛動力系統的相互關係,分析相關參數對於系統整體的影響,並且進行系統匹配的設計,期望用匹配的方式,使動力系統達到最大的輸出效益。研究以車輛模擬軟體ADVISOR作為分析工具,首先研究傳統引擎車的匹配性質,分析變速器換檔時機、檔數及引擎功率的影響。接著研究油電混合車的匹配性質,分析單自由度及雙自由度混合動力系統,藉由調整機構參數,討論車輛匹配的情形。利用分析的結果,發展混合動力車的匹配設計方法。最後以三自由度行星齒輪機構為目標,進行油電混合車的匹配設計,對於設計方法進行驗證。本研究發展完整的分析方法,釐清設計方向,整理及分析相關系統的匹配參數,比較各種系統的特性,提供車輛設計與改進時作參考。
The purpose of this study is to analyze the interrelations of parameters of the vehicle power system, and also to develop the scheme of designing a matching system – using ADVISOR as a simulator – for improving vehicle performance and decreasing fuel consumption. The first step is to find the parameters of matching system, included the timing of changing gears, the numbers of gears and engine power characteristic. Furthermore, the influences of the mechanical parameters are analyzed by comparing with one and two d.o.f. (degree of freedom) hybrid systems. Based on the result, the method of matching hybrid system is strictly constructed. In this study an example to design a new hybrid vehicle by using three d.o.f planetary gear mechanisms is also presented. This study develops a completed method to match vehicle system, which can be a helpful reference for industries.
