| Summary: | 碩士 === 國立臺北科技大學 === 車輛工程系所 === 104 === This study analyzed a Plug-in Hybrid system, EV-X4, which integrates three power sources, engine, generator/motor, and motor. This hybrid system have four driving mode, Electric Vehicle (EV) mode, Extend Range (ER) mode , accelerate (Boost) mode and parallel mode. Each mode uses appropriate strategy to drive vehicle. The energy management of the EV-X4 hybrid system is based on rule-based control strategy. When driver require more power than engine provided to accelerate vehicle, generator/motor and traction motor will work together. In normal condition, system will use more efficient driving mode, and let power sources work in high efficiency area to save energy and fuel. A hybrid electric vehicle model established in MATLAB/Simulink is used to test the performance and fuel economy. The results are analyzed and discussed., and EV-X4 hybrid system will compare with Honda Accord hybrid in performance and fuel economy.
