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%.
