Abstract
This paper proposes a control system using dynamic forces between 4 wheels and road to improve vehicle handling and stability under severe driving conditions using yaw moment generated from the distriution of braking forces of four tyres (DYC). First, we propose a nonlinear 4-wheels vehicle model. And the longitudinal motion, the lateral motion, the yawing motion, and the load shift are taken into consideration in the proposed analysis model. In addition, nonlinear caracteristics of tyre are also taken into consideration by Magic Formula function. Then we design control system using model matching control method. In order to confirm the effectiveness of this system, the computer simulation are conducted.
