In this study, modeling of pre-transmission parallel hybrid, post- transmission parallel hybrid, serial hybrid and conventional vehicle structures in Matlab / SIMULINK environment. Average fuel consumption values for different driving cycles were obtained on the vehicle models created and compared. The power, gear range and regenerative brake control of the parallel hybrid vehicle were provided by the control algorithm developed by the fuzzy logic method. Transfer functions representing the vehicle's power system have been created for all vehicle structures. Rolling, acceleration and aerodynamic forces acting on the vehicle are included in the model. The torque / speed and specific fuel consumption map of the 1.8 liter "ZR-FXE" gasoline engine was used in the internal combustion engine model. In the electric motor model, the torque / speed and efficiency map of the "Ashwoods / Elmo-D576" brand electric motor was used. A 7-speed DCT transmission is used in all vehicle structures. The vehicle uses a 5 kWh energy capacity, hum ion battery pack. The battery model was created with the equivalent circuit method Rint method. It was determined that the lowest average fuel consumption values for US06, FTP75, NEDC, EUDC driving cycles were obtained as 5.73, 4, 3.96 and 4.18 L / 100 km with the pre-transmission parallel hybrid vehicle structure controlled by fuzzy logic method. In the ECE15 driving cycle, it was determined that the serial hybrid vehicle structure has the lowest average fuel consumption with a value of 3.62 L / 100 km. In the ECE15 driving cycle, where regenerative braking use is most effective, it has been observed that the series, pretransmission parallel and post transmission parallel hybrid vehicle structures save 14.22%, 11.5% and 9.95% respectively.
