Efficient control strategy for reducing fuel consumption in parallel hybrid electric vehicles, based on engine and electric motor efficient operating points

Various types of control strategies have been presented about HEVs with focused on so many different parameters for example pollution, accelerating performance, traction efficiency, fuel consumption, and so on. All of these strategies can be useful for each proposed applications and present their specifications. Regarding the global situations of automobile and fuel market a new look to the vehicle design sense more than other times. This paper presents a control strategy to reduce the volume of fuel consumption to the lowest possible level and also try to hold the engine operating points in efficient level.
