Fuel-Efficiency Improvement by Component-Size Optimization in Hybrid Electric Vehicles

Publication Year: 2023

Author(s): Srivastava S, Maurya SK, Chauhan RK.


Hybrid electric vehicles (HEV) are essential in sustainable transportation systems. The component size of HEV plays a vital role in the fuel efficiency of vehicles. This paper presents a divided rectangle (DIRECT) method for component sizing of vehicles to ensure better fuel efficiency and satisfying drivability. A state–space model was used to represent the design problem. This DIRECT optimization algorithm solved a constraint multi-input multi-output optimization problem. The efficacy of the algorithm was tested with standard drive cycles, including drive cycles for Indian urban and highway conditions representing various driving scenarios in the country. The simulation results illustrated the effectiveness of the proposed algorithm.
