道路耦合並聯式複合動力車輛之能量管理策略
An Energy Management Strategy for Through-the-Road Parallel Hybrid Vehicle
摘要
本研究針對外掛式並聯式複合動力車輛建立一套以節能為主要目標，並同時考慮成本與實用性的能量管理策略，此複合動力系統原本為一純汽油車型，包含引擎及變速箱負責驅動前軸，於後軸額外加上電池、驅動器及馬達形成複合動力系統。本文首先將針對此複合動力系統的架構進行評估與初步分析，確認行車模式的種類以及各模式下各個動力元件的運作情形，進一步針對展開的行車模式，發展能量管理策略所需具備的功能，包含模式切換、動力分配與變速箱換檔策略等模組，以各種車輛行車時的狀態分別設計各個模組，盡量使用馬達、引擎若要使用時則使用於效率較高區間的原則進行開發，並將各功能進行整合並放入車輛模型進行模擬驗證。本研究會利用Matlab/Simulink/Stateflow設計與開發能量管理策略，並利用Matlab/Simulink建立複合動力車輛之車輛模型並與能量管理策略進行整合，以MiL(Model in the Loop)進行能耗測試與分析，針對模擬結果對本研究之系統架構與能量管理策略進行探討。

This research aims to establish an energy management strategy (EMS) for an add-on parallel hybrid vehicle, aimed for low fuel consumption without raising the cost and maintain the practicality. This HEV structure was originally a ICV equipped with a gasoline engine and a gearbox, with add-on battery, motor and invertor to complete the HEV system. First, this research evaluates and analysis the structure of this HEV powertrain, develop a set of driving mode accordingly. Later on, we establish the main functions that this EMS requires, including mode switching, power splitting and gear shifting. We develop each function according to the situations that a vehicle could encounter during a ride, with mainly using the electric motor and operating the engine at high efficiency region as the main policy. Then we combine each function and integrate with the vehicle model to simulate the strategy and fuel consumption.In this research, we use Matlab, Simulink, Stateflow to develop our EMS and Matlab, Simulink to develop our vehicle model. The EMS and the vehicle model are then integrated and verified under Model in the Loop simulation. Results of the simulation is then analyzed, with its pros and cons discussed after analyzation.
