This study developed a new hybrid power system which consisted of two continuous variable transmissions (CVT). By matching between the engine, motor, generator, and dual CVT system, this integrated power system can take advantages of components. The hybrid vehicle can be driven by the internal combustion engine (ICE) or electric motor (M) alone, or by these two power sources together when vehicle is driven in hard acceleration or high load. The integrated hybrid system could provide better fuel economy. The energy management of this integrated system controls the power systems based on rule-based control strategy to achieve better fuel economy. When the vehicle driving power demand is low, the ICE which is operating in the low efficiency region. The ICE is shut down, and the vehicle is driven by motor only. When the vehicle driving power demand is high, ICE would operate in the high efficiency region. The vehicle could be driven by ICE. This strategy would operate ICE only in optimal efficiency region to improve the fuel economy. In this research, the vehicle simulation model was built in Matlab/Simulink environment. The model simulation was according with the vehicle dynamics test, and the analysis and discussion of the simulation results was present.
