The Stability Control of Individual Drive Electric Vehicle Based on Torque Distribution

Abstract

A direct yaw moment control (DYC) method based on optimal predictive method is proposed to achieve an external yaw moment which is as low as possible. This control method calculates the necessary moment according the vehicle condition, and then optimizes the distribution of drive/brake torque to achieve the necessary yaw moment considering the constraints of actuators. The effectiveness of the designed controller is investigated by simulations. The simulation results indicate that a satisfactory handling performance can be achieved when the proposed controller is applied.
