The worldâ€™s heavy dependence on vehicles which utilize hydrocarbon fuels as a primary power source has renewed the interest in electric and hybrid vehicles for industrial, commercial, and public use. The primary objective of this movement is centered on increased efï¬ciency in energy usage for transportation. Hybrid vehicles which utilize an internal combustion engine as a linear generator, converting energy stored in hydrocarbon fuels into electrical power, could serve as a transitioning technology. The free-piston enhanced hybrid vehicle (FPHV) could potentially ï¬ll this role. The present work contains a theoretical and numerical approach to analyzing and optimizing the usage of energy within a free-piston enhanced hybrid vehicle given urban, highway, and aggressive driving proï¬les. An electromechanical model representing the free-piston hybrid vehicle is developed and optimized based on mass of energy sources carried.
