摘要

本論文主要對一種新型強型複合電動系統做性能模擬，此系統（Planetary gearset and Dual Clutch ,PDC）稱為行星齒輪組雙離合器系統與豐田複合電動系統(Toyota Hybrid System,THS)同是屬於動力分割電控無段變速系統(Power Split e-CVT)，ECE-40、NEDC和WMTC三種不同的行車型態用來做性能模擬並探討鉛酸電池、鎳氫電池及鋰離子電池，對PDC系統性能的影響。
PDC系統提供五種操作模式：雙馬達電動車輛模式(Dual-Motor EV Mode)、切換無段變速模式（s-CVT Mode）、引擎驅動模式(Engine-Driven Mode)、動力分割電控無段變速系統模式(Power Split e-CVT Mode)，和增強模式(Boost mode)。首先推導PDC系統內動力源的扭矩和轉速的方程式。動力源是使用市售車輛之性能圖，依比例調整至本系統適用標準。通過採用一個全區域搜索的方法,油箱到車輪的效率和操作點達到最佳化，並在特定車輛的速度和輸出負載進行了計算。模擬的結果發現到三種不同的電池模組中，鋰離子電池對於穩定性與效能方面是明顯優於鉛酸電池與鎳氫電池，其放電深度是三者中最小。有無回升剎車對於不同的電池模組，比較三種電池下來，發現到鉛酸電池的差異是最小的。而燃油經濟效益最好的行車型態為ECE-40，放電深度變化量變化最小的為WMTC part1，有無回生剎車對於燃油經濟效益的影響，差距最小的是NEDC行車型態。

This thesis aims at performance simulation on a novel full type hybrid electric system called Planetary gearset and Dual Clutch(PDC). This system and Toyota Hybrid System(THS) are both power split electronic continuously variable transmission(power split e-CVT) systems. Three different driving cycles, i.e. ECE-40,NEDC and WMTC, are used for simulation. Furthermore, the influence of lead acid batteries, nickel-metal hybride batteries and lithium-ion batteries is investigated.
PDC consists of five operating modes：Dual-motor Electric Vehicle mode(Dual-motor EV),switch CVT mode(s-CVT),Engine-driven mode, Power Split e-CVT mode and Boost mode.First,the relations of torque and rotational speed of the power sources in PDC system are derived . The performance maps of the power sources used in market are utilized and scaled in proportion to standard specification suited to PDC system. Through a global research method ,the tank-to-wheel efficiency as well as operating point are optimized.Simulation is then carried out under specific vehicle speeds and driving loads.
The simulation results show that to three different battery modules, the lithium-ion battery for the stability and performance aspects are much better than lead-acid batteries and nickel-metal hydride batteries, the discharge depth is the smallest of the three batteries. Have regenerative braking for different battery modules, Comparison of three battery , we found differences lead-acid battery is minimal. The best fuel economy driving patterns for the ECE-40, the smallest change in depth of discharge is WMTC part1, whether the regenerative braking impact fuel economy, the gap is the smallest NEDC driving cycle.
