Reducing the Fuel Consumption and Pollution by Designing the Optimal Energy Management in Hybrid Vehicles


  • Department of Mechanics, Khayyam Higher Education Center, Mashhad, Iran, Islamic Republic of


Objective: One of the main factors in fuel consumption and pollution is transportation and automotive industry. Today one of the most effective methods to deal with pollution and fuel consumption is developing the hybrid electric. Method: This type of propulsion system has been used of two combined power sources of the internal and electric combustion engine alongside each other for providing the required power to drive the vehicle and in addition to that, they remove each other's limitations by using the overlapping simultaneously. Results: One of the main important parameters in optimal hybrid vehicles performance is the energy management system appropriate designing between the power sources that it is the main factor in optimal performance of hybrid vehicles. Therefore, in this research, first the hybrid vehicle modeling is presented, including the combustion engine, gearbox, electric motor and battery with the association of Advisor-Simulink. Then, the optimal energy management system is designed for the optimal distribution of power between the combustion and electric engine according to the fuzzy logic. Findings: It shows that it can be reduced the fuel consumption and pollution by using the electric auxiliary power source along with combustion engine and optimal energy management in different conditions. Applications/Improvements: Finally, the sensitivity analysis of the effect of weight on vehicle performance will be assessed.
