Abstract
Using stabilizing yaw-moment diagrams, the authors analyzed three methods of active chassis control for their effect and effective ranges during cornering maneuvers. The following results were obtained: controlling the transverse distribution of driving and braking forces cancels the changes in a vehicle's dynamic characteristics caused by acceleration and deceleration. Controlling the distribution of roll stiffness is only effective in ranges with high lateral acceleration, and the effect varies depending on the longitudinal weight distribution. Controlling the rear wheel steering angle is most effective in a range with a small side slip angle, but this effect decreases with an increase in the angle, especially during deceleration.
