摘要

由於雙動力源的混合動力系統擁有低油耗及低污染之優點，近年來被廣為探討，並依其不同之硬體架構，發展出各種控制策略。因此本研究之目的即在利用最佳化方法，設計混合動力機車之控制策略。本文所提之混合動力機車採用與傳統機車相同之硬體架構，而後輪則以變繞組式輪轂馬達取代。能源管理系統以駕駛者決定之動力需求為參考輸入，採用以法則為基礎之控制策略，決定引擎與馬達之動力分配，盡量避開引擎於低效率區域運轉。本文透過動態規劃(Dynamic Programming)方法之觀察結果，歸納引擎之高效率區域，設計控制策略。並利用簡單形搜尋法(Simplex Method)，以ECE40行車型態為依據，搜尋出最佳化引擎高效率區之參數。最後以整車模擬程式進行模擬，並針對其結果加以分析探討。

Hybrid system technique has been widely studied recently due to their potential for significantly improving the fuel economy and emissions. Various control strategy has been proposed for different hardware configuration of the hybrid system. The goal of this paper is to design the control strategies of Hybrid Electric Motorcycle (HEM) using optimization method. A HEM based on the traditional scooter and the rear wheel replaced by a variable-winding brushed wheel motor is proposed in this thesis. By designing the control strategies, we can prevent the engine operating in the inefficient region. According to the driver’s demand, a rule-based control strategy is used to generate the required engine and/or motor power commands. The control strategy is developed by analyzing the result of dynamic programming for obtaining the engine high efficiency region. Over the ECE-40 driving cycle, a simplex method is further used to obtain the optimal boundary values of the high efficiency region. A detail simulation model is used to verify the proposed strategy and obtain its fuel consumption and emissions.
