交通工具是人類文明社會中不可或缺的文化,而且以車輛數量佔大多數,然而車輛動力的主要來源是內燃機,內燃機主要燃料為石油,且內燃機會有排放污染的問題。近年污染日益嚴重,CO2造成溫室效應使全球氣候暖化,天氣異常現象越來越嚴重。隨著能源短缺油價上漲和環保意識抬頭,車輛動力源需要改變。因此,零排放污染,動力來源來自電能驅動馬達的純電動車(Pure Electric Vehicle, PEV)是必須取代現在車輛的動力來源。但目前電動車之續航能力差性能表現較差,沒辦法取代傳統內燃機車輛的性能,因此結合內燃機和電動馬達的複合動力車(Hybrid Electric Vehicle, HEV)可以互補其短,降低排放污染增加續航能力,動力性能表現也比純電動車好。 本研究中採用的複合動力系統為並聯式複合動力系統,使用1.3L SI內燃機與一體式馬達/發電機當作動力來源,動力整合機構將兩者動力作結合。並且搭配使用eCVT(Electrical Continuously Variable Transmission)無段變速機構,車輛負載變化時可以調整傳動減速比,使引擎和馬達之動力輸出皆能保持在最佳運轉狀態。配合科專計畫,架設並聯式複合動力系統平台,驗證複合動力系統理論,經過模擬分析評估系統,並且改善系統使其更為理想。
The emissions of engine cause the serious air pollution and damage the environment. Furthermore, the energy crisis influence the fuel of engine in consequence the replace power source of vehicle is needed. The zero emission’s Pure Electric Vehicle (PEV) could solve those problems. However, there still have some technical problems of PEV. The drawbacks of PEV the power source provide the mileages and the performance could not similar to engine vehicle. Therefore, the Hybrid Electric Vehicle (HEV) has engine and motor power. Those two powers could use particularly or together. The HEV could lower the emission of engine, increase the mileages of electric motor and the performance could similar to engine vehicle. In this study use a parallel hybrid power system. The power sources of hybrid power system use a 1.3 liter engine and a motor/generator combines by a power integration mechanism. The Electrical Continuously Variable Transmission helps system operate more efficiently.
