Abstract
At present, the expansion in vehicle population has contributed to the increase in carbon emissions and has led to an even greater increase in the need for fuel. In this way, the hybrid vehicle (HEV) and the electric vehicle (EV) are being introduced to reduce fuel consumption and exhaust gas emission instead of conventional vehicles. The study of parameters for the hybrid electric vehicle is important to design the powertrain of the vehicle. The parameters of hybrid vehicles consist of the rate of internal combustion engine (ICE) power, transmission gear ratios, motor maximum torque and power, capacity and power of battery. The vehicle model with the regenerative model is built to calculate the regenerative energy for driving on a road condition. The design purposes to match the vehicle with the specified performances, like as speed and acceleration. Many parameters are chosen from analysis of this results. And then, as a result, fuel consumption of test vehicle model reduces 15% than the conventional vehicle in this study.
