摘要

本研究之目的為建立油電混合動力系統理念之分析與合成的方法，並利用此方法針對一引擎一電機以及一引擎兩電機之系統進行評估。本研究首先探討構造之自由度，並建立構造之動力流規則，分析動力流及運動方向、扭力方向之關係，可以對系統的功能與特性發展一套分析方法。然後應用理念分析的方法與規則來建立系統化的合成方法及步驟，以產生系統所有可能之概念，並針對一引擎一電機及一引擎兩電機之系統建立構造圖集與動力流圖集。最後本研究以引擎操作限制、動力模式、行車模式、能量循環等項目來評估所有可能的設計概念，可以揀選出合適的混合動力系統，其中部分系統雖有不充分之動力模式，但應用離合器與制動器可加以改善，達到系統功能的完整性。本研究利用此方法可有效地分析及合成混合動力系統之設計概念，並對系統做定性之評估。本研究也完整地整理出所有一引擎一電機以及一引擎兩電機系統可能之設計概念。

The purpose of this study is to develop a method for analyzing and synthesizing hybrid systems, and to establish and to evaluate the concepts of all possible hybrid systems composed of 1 engine, 1 electric machine and 1 engine, 2 electric machines. At the beginning of the research, the degrees of freedom of mechanisms are discussed, the rules of power flow in the mechanisms are established, the relationships between torque, speed, and power flow are analyzed, and the method for conceptual analysis can be developed. Then, a systematic approach for conceptual synthesis can be established based on the methods and rules of conceptual analysis, which can be used to generate all possible concepts of the systems, and to build the atlas of structural graphs and power flow graphs. Finally, all possible design concepts of the systems are assessed in terms of engine operating limits, power modes, driving modes, and power circulations. The lack of power modes in some concepts can be modified through the application of clutches. To sum up, through the method developed in the research, design concepts of hybrid systems can be analyzed and synthesized efficiently, qualitative evaluation of systems can also be made. All possible design concepts of hybrid systems composed of 1 engine 1 electric machine and 1 engine 2 electric machines are also summarized in the research.
