Study and Simulation of Based-fuzzy-logic Parallel Hybrid Electric Vehicles Control Strategy

With the increasing demand of fuel and emission hybrid electric vehicles (HEV) with dual power sources, the engine and the motor, has been one of the development ways of clean automobiles. In the research on hybrid electric vehicles, the control of the powertrain is the key issue. According to parallel hybrid electric vehicles, this paper used fuzzy control to realize electric assist control strategy and membership function was optimized for increasing fuel economy and decreasing emissions
