摘要

本研究會針對插電式串並聯式複合動力電動車建立一套節能為主並兼顧車輛性能之能量管理策略，此複合動力車輛前軸擁有引擎、ISG與高功率永磁馬達，後軸擁有高功率感應馬達等多動力源，各動力源同時搭配著離合器、單速減速齒輪與雙速變速齒輪箱特定的配置，構成多自由度的動力系統架構。本文首先會對其動力系統架構進行評估與分析以初步歸納與分工能量管理策略所需進行之工作項目，進一步依據各工作項目將能量管理策略功能模組化。功能模組分別為動力元件性能限制模組、車輛扭力需求計算模組、動力元件操作組合選擇模組、變速箱檔位控制模組、車輛驅動與回充制動扭力分配模組與增程發電控制模組，以依據不同的駕駛者需求與車輛狀態，決定適當的動力元件操作組合，並將動力元件皆操作在較高效率區間之策略原則，去進行能量管理策略各個功能模組的設計。
本研究會利用Matlab/Simulink/Stateflow軟體建立設計之能量管理策略，並與利用dSPACE ASM以及Matlab/Simulink建立之插電式複合動力電動車模型進行整合，以模型迴路模擬(Model in the Loop)進行性能與能耗模擬，針對模擬結果進行本研究設計的能量管理策略其特性與優缺點探討。

This research is about establishing an energy management strategy which aims to enhance efficiency of energy consumption and performance of plug-in series parallel hybrid electric vehicle. There are many power components in this PHEV structure like engine, ISG and high power permanent magnet motor in the front axial, and high power induction motor in the rear axial. The power components are matched with single reduction ratio gear, clutch, or transmission specifically to make PHEV structure a high degree freedom system. First, this research evaluates and analyzes the PHEV powertrain structure, then distributes what the energy management strategy (EMS) should do. Later on, the EMS according to the tasks would be modularized. The function module includes Component Capacity Calculate module, Vehicle Torque Demand module, Function State module, Gearbox Control module, Torque Split module, and Torque Charging module. In consideration of driver's requirement and status of vehicle, the proposed flow can utilize these function modules to seek the optimal combination of power components while reaching high efficiency.
In this research, we utilize Matlab, Simulink, Stateflow to develop the EMS and dSPACE ASM, Matlab, Simulink to develop the PHEV vehicle model. Integration of the EMS and the vehicle model is implemented under Model in the Loop simulation. Result of the simulation is analyzed while further advantages and disadvantages of the EMS designed in this research is dicussed.
