本研究主要目標在於建立一套應用於插電式雙軸並聯式複合動力車之能量管理策略,此種架構的複合動力車型具有引擎、發電機、驅動馬達與變速箱等四個自由度。本文利用最佳化方法搜尋各動力系統間最佳操作區域,透過此結果建立一種階層式控制策略,依序為變速箱控制、前後力矩分配與發電命令控制,用以簡化多自由度控制的複雜性與整合PHEV的策略行為。能量管理策略使用模糊規則的方法建立使策略在模式切換上具有連續性,以減少系統負擔並增加舒適性,且加入行駛里程的考量以發揮PHEV的優勢。本研究利用Matlab/Simulink以Luxgen SUV7汽油車型為基礎,搭載複合動力系統建立複合動力虛擬車輛模型,並透過汽油車型模擬驗證模型建立方法準確性後,再透過在不同測試法規的情況下探討本文能量管理策略之特性與優缺點。
The goal of this research is establishing an energy management strategy for plug-in biaxial parallel hybrid electric vehicle. For this HEV structure has four degree of freedom with engine, generator, traction motor, transmission, so it is very complex. This research uses the optimal method to find up the optimal operation area for each power system, and using the optimal result to building the hierarchical control strategy to reduce the complexity. The hierarchical control strategy is transmission control, torque split control, generator control sequentially, and using fuzzy logic control to make the switch among modes more smoothly, and reducing the loading for the hybrid system. Finally, Using the consideration of the desire distance make PHEV more excellent. In this search, establishing the hybrid electric vehicle model base on Luxgen SUV 7 by Matlab/Simulink, and identify the ICE model by the experiment data to make the method of the model building. Using this model to simulating the energy management strategy, then this research will investigate the advantage and disadvantage of this strategy by different test.
