Modeling and Simulation of the Hybrid Powertrain for the Use in Urban Vehicle

This paper presents the results of mathematical modeling and simulation involving vehicle properties designed with a simple parallel hybrid powertrain and a planetary gear for the use in buggy hybrid vehicle. This system consists of a planetary set and combines two power sources: combustion engine (ICE) and electric motor (EM). The powertrain consists of a simple planetary set and two additional gears with constant speed ratios. A wide range of transmission ratios is obtained due to various speed of electric motor which is directly connected to the sun gear in the planetary set. The model of the whole vehicle has been developed in MATLAB/Simulink environment. It describes the vehicle, internal combustion engine, electric motor and a planetary set.
