本研究之目的在於分析混合動力系統動力元件間相互耦合所產生之系統特性,並評估各類混合動力系統效率,期望在選用或設計混合動力系統時選擇適切的耦合方式以增進系統運作效率。本研究首先介紹混合動力系統之基本概念與操作模式,並對混合動力系統之動力元件、系統負載與耦合機構進行分析。接著由動力元件與系統負載間轉速與扭力關係進行動力系統分類。研究再針對各類耦合方式對系統效能提升的差異進行分析,以車輛模擬軟體ADVISOR作為分析工具,進行系統元件配置、參數設定以及系統控制策略設定,分析引擎效率、能量傳遞途徑效率以及油耗表現,完整了解系統之特性。研究最後以一個創新油電混合動力系統作為評估與分析案例,對此創新系統配置動力元件、參數設定與控制策略設定,並與相似類型之混合動力系統進行比較。本研究分析與評估混合動力系統特性,提供混合動力系統配置與設計時參考。
The purpose of this study is to analyze the system characteristic of coupling multiple power unit in hybrid power trains and to evaluate the system efficiency of varies kind of powertrains. The goal is to identify the proper coupling type to enhance system efficiency. This study starts from introducing the conceptual hybrid system and its operation mode. Power unit, system loading and mechanical coupler in hybrid power train are analysis in detail. The power trains are then sort by the speed and torque relation between power unit and system loading. Using ADVISOR as the simulation tool, this research compare different kinds of hybrid power trains by their engine efficiency, transmission efficiency and fuel efficiency. Finally, a novel hybrid system is evaluated in this study. The novel hybrid system is simulated in ADVISOR and the system unit, design variable, control strategy is assigned. The novel hybrid system is compare with Toyota Hybrid System to fully understand the potential of this system. In this research, the characteristic of hybrid system is analyzed. The result could be a considerable consultation for design hybrid power trains.
