Abstract

he most significant weakness of hybrid electric vehicles (HEV)is the high construction
cost and the complicated control strategies due to multiple power sources[1],[2] .In this paper
a new developed configuration of hybrid vehicle is presented. The new configuration is
simple, cost-effective and easy to implement .The differential unit, which acts as mechanical
torque-overflow keeps engine torque within a predefined value . This is achieved by the aid of
torque loop attached to one terminal of the differential.The new configuration proved to act
continuously varying transmission (CVT)and also can perform efficient control strategies .
Minimum emissions can be assured by running the IC-engine within best engine performance
zone which is characterized by engine torque and engine speed.
