A Torque Vectoring Control System for Maneuverability Improvement of 4WD EV
This paper studies the improvement of the handling performance of 4WD EV driven by in-wheel motors under regular driving conditions.Fundamentally the structure of torque vectoring control (TVC) system for handling control consists of two control layers.The upper layer is a model following controller which makes the vehicle follow the desired yaw rate limited by the side slip angle and lateral acceleration.The torque distribution constitutes the lower layer.Several simulations based on veDYNA/Simulink are conducted to verify the effectiveness of the control system.It is clarified that the control system exhibits satisfactory performance in both open and closed loop maneuvers and the agility of the electric vehicle is improved.
