NEW DRIVING WHEELS CONTROL OF ELECTRIC VEHICLE

Abstract

New technologies allow the development of
electric vehicles (EV) by means of electric motors
association with static converters. All mechanical
transmission devices are eliminated and vehicle wheel
motion can be controlled by means of power electronics.
The proposed propulsing system consists of two permanent
magnets synchronous machines (PMSM) that ensure the
drive of the two back driving wheels. The proposed control
structure-called independent machines- for speed control
permits the achievement of an electronic differential. The
electronic differential system ensures the control of the
vehicle behavior on the road. It also allows to control,
independently, every driving wheel to turn at different
speeds in any curve. This paper presents the study and the
control strategy of the electric vehicle driving wheels.
