With automobile propulsion energy sources turning away from petroleum, the evolution
of technology naturally lends itself to electrical hybrid vehicle architectures relying on
alternatives as a primary electrical energy source. This thesis presents a design solution of
a direct-drive and drive-by-wire prototype of a hybrid extended range electric vehicle
(EREV) based on a dune buggy test bed. The developed setup eliminates nearly all
mechanical inefficiencies in the rear wheel drive transaxle drivetrain. All controls have
been purposely designed as a duplicate set to allow for full independent control of both
rear wheels in a truly independent architecture. Along with the controls supporting the
design, the motors have been mounted in a near wheel fashion to adequately replace a
true hub motor setup. In addition, by-wire throttle and by-wireless brakes in a servomechanical
fashion have been developed. The by-wireless braking system is used to
control regenerative braking for the rear of the vehicle only allowing for the front brakes
to be the primary means of braking as well as a mechanical safety redundancy. This
design allows for developments in the areas of truly independent electronic differential
systems and studies of the effect of near wheel motor setup. The efficiencies gained by
the design solutions implemented in this thesis project have shown their ability to be used
in a functioning motor vehicle. Direct gains in mechanical efficiency as well as the
removal of a non eco-friendly gasoline powertrain have been attained. In addition, an
electric architecture has been developed for further research in future studies such as
vehicle stability control, traction control and all-wheel-drive architectures.
