Optimization of fuel economy for a multimode plug-in hybrid electric vehicle using Atkinson thermodynamic cycle engine

Recently, Plug-in Hybrid electric vehicles become a sustainable solution to strike a balance between performance and fuel economy. For a multimode PHEV, the car switches among three operation modes; namely electric mode, series mode, and parallel mode to maximize fuel economy based on the driving co...
