Refueling strategies of autonomous hybrid vehicles

Abstract

Fuel consumption prediction and recharging strategies are crucial fields of autonomous hybrid vehicles. In our paper based on literature review the currents trends of hybrid vehicles are compared and working principals of hybrid strategies created for different types of hybrid drivetrains were described. The fuel management, basics of the range estimation in hybrid vehicles are displayed. Analyzations of the factors affecting the fuel consumption and energy management were made, along with an estimation of the order of magnitude of these factors, based on experiments done by EPA. Main fuel consumption influencers are listed and a real word test is carried out in a highway measurement. It was focusing on the affection on the fuel consumption, caused by the additional consumers of the vehicle has been carried out. Evaluation of this measurement was made and conclusions were drawn about the efficiency changes of the vehicle.
