Impact of Vehicle Hybridization on Fuel Consumption Economy

Abstract

Air pollution, limited number of known petroleum resources and increasing of greenhouse gases have led the governments and researchers to have more investigation on Hybrid Electric Vehicles. Considering technical availability and manufacturing facilities with regarding to the final vehicle price, hybridization of conventional vehicles could be a better choice than designing and manufacturing a new hybrid electric car.

Parallel-Series hybrid electric vehicles (power-split) which is used in this study have low pollution and fuel consumption compared to other hybrid structures and could be an appropriate choice for hybridization. In addition, electric assist control strategy (EACS) is used as an efficient strategy in this study since this method could decrease fuel consumption and engine emission significantly for conventional vehicles and has been used in most of successful commercial hybrid vehicles recently.

Gt-Power software is used for modelling the Peugeot 206 vehicle platform and the proposed control strategy in this study. For the testing and validation, standard international cycles for urban and highway (FTP-75 and HFET) are used for both conventional and hybrid vehicle and results showed significant reduction in fuel economy for both cycles, in particular for urban cycle, this control strategy had the best efficiency and fuel consumption reduced up to 27.6%.
