本論文針對輕型電動車之動力系統提出了系統性的方法來進行設計和分析。電動車輛的扭力及功率需求分別由滿足三個不同驅動目標的函數來設計。平衡考量車輛最高車速、爬坡能力及加速性能之設計,以決定電動機驅動器及電池模組所需的額定功率。本論文由不同的觀點提出三個設計策略以提供各種使用者更佳的動力配置建議。輪轂馬達在效率及精簡動力系統上占有優勢,而結合齒輪箱的傳統馬達在爬坡及加速方面擁有較佳的性能。最後,採用著名的車輛模擬軟體「先進車輛模擬器」(Advance Vehicle Simulator,ADVISOR)來驗證本論文車輛動力設計結果的有效性及正確性。
This thesis proposes a methodical procedure for the design and analysis of the power train of light electric vehicles. The driving power and torque requirements of the designed vehicle are respectively computed by three power demand formulas satisfying the designated driving goals. The proper power rating of motor driver and battery pack module are determined by trading-off the performance indexes among the maximum speed, climbing and acceleration ability. Three design strategies are presented to provide the better suggestions for different design aspects. The In-wheel motor type is superior in efficiency and can be more compacted in the driving train. The combination of traditional motor and gear box, however, is outstanding in climbing and acceleration ability. Finally, the effectiveness and rightness of the design results are verified by the well-known simulation software of vehicles “ADVISOR”(Advance Vehicle Simulator).
