Abstract
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.
