Electric Vehicle Range Extension Control System Based on Front- and Rear-wheel Sideslip Angle and Left- and Right-motor Torque Distribution

Abstract

In this paper, the range extension control system based on the least squares method is proposed for electric vehicles with in-wheel motors and front active steering. We propose a method that distributes front and rear wheel sideslip angles and the difference in the driving force between the left and right motors because of the lateral force and yawmoment. The proposed method enables a reduction in the driving resistance generated because of the front steering angle. In fact, the mileage per charge is increased to about 200m/kWh. Simulations and experiments are carried out to confirm the effectiveness of the proposed method.
