SUMMARY 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.
