This paper will discuss the control strategy of energy management and analyze the general performance of hybrid electric system, and then based on this specific control strategy to manufacture an Energy Management Unit (EMU), which will distribute energy to individual power unit. The energy management system takes driver's demand for power as a reference for input, and it adopts the rule-based control strategy to decide the power distribution among Electric Motor (EM), generator and Internal Combustion Engine (ICE) in order to keep ICE operating in the most efficient area all the time. The system adopts ICE and EM as the two sources of power, and further integrates the two powers through the power integrating & distributing mechanism of inverse differential gear (IDG); in addition, while the load on the vehicle changes, the mechanism of Electrical Continuously Variable Transmission (eCVT) will adjust the reduction ratio of transmission for ICE and EM to achieve a more stable power-output. The computer analysis applies Matlab/Simulink software to set up the components of the system via the way of modularization, and then makes simulation according to the dynamic module of the vehicle in the NEDC2000 driving pattern. Based on the result of computer analysis, this paper attempts to make further examination and discussion on the above subjects.
