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

摘要

In this paper, a 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 the front and rear-wheel sideslip angles and the difference in the driving force between the left and right motors resulting from the lateral force and yaw moment. The proposed method allows a reduction in the driving resistance generated due to the front steering angle. In practice, the mileage per charge is increased to about 200 m/kWh. Simulations and experiments confirm the effectiveness of the proposed method.
