摘要

由於機車之重量與體積限制，本論文探討一種微型複合動力系統，提供少量的電動馬達輔助動力，協助機車起步並加速，以改善燃油消耗量，並降低廢氣排放量。研究之主要目的在於探討該型複合動力系統之參數設計對省油功效，以及污染減量之影響。整個研究以屏東市區機車的駕駛模式為依據，配合等停紅綠燈之怠速熄火策略，設計該微動力輔助的策略與硬體系統。研究內容包括動力輔助策略設計、動力系統設計、數值模擬分析、與實車實驗等。

研究中，首先設計機車的動力輔助系統以及動力分配策略，然後分別利用軟體模擬與底盤動力計進行實測，分析與評估所設計策略之可行性與省油功效。最後，將所設計的動力傳動系統與動力輔助策略，實現於一部125cc機車上，於底盤動力計進行市區行車模式實驗，以分析機車各項關鍵參數之變化，並且驗證其實際的省能成效。實驗結果顯示，所設計的微動力輔助系統，在市區行駛模式下，利用最少的馬達電能，可以減少原機車油耗22.5%。

This thesis is focused on parameter design of scooter micro-hybrid power system. The study is mainly based on the property of the scooter on a driving mode measured from driving in Pingtung city, Taiwan. Integrated with an idle-stop-and-go strategy, the system provides a small amount of power to assistant the internal combustion engine (ICE) of the scooter for its start and acceleration operations. The purposes are mainly on improving fuel consumption and reducing exhaust emissions. The works include design of power management strategy, design of system parameters, and performance evaluation.

The study was preceded by firstly design a power assistant system as well as the associated power management strategy for the scooter. Then key parameters that affect the scooter performance were studied through numerical simulations and experiments. Finally, the designed system was implemented on a 125cc scooter. Its performance in reducing scooter ICE fuel consumption and exhaust emissions were evaluated on a chassis dynamometer based on the measured city driving mode. The experimental results have shown that, with a small portion of assistant power to the ICE of the scooter, the designed system can improve the fuel consumption rate up to 22.5% compared with the original scooter on the city drive mode.
