The purpose of this paper is to clarify controllability of the vehicle stability and manoeuvrability by means of active suspension control as well as ride comfort. It is well known that the dynamic responses of chassis on the uneven road surface produces large effect on the vehicle cornering properties, i.e., the stability and manoeuverability. A half car model with active suspension is used for pitching and bouncing motions and two-wheeler model of front steering type is provided for lateral and yawing motions. Several responses of the models with Hoo controller are analysed by computer simulation when the vehicle travels on a rough road in a steady state cornering. Suppression of external yaw moment and improved stability by active suspension control is demonstrated. For the covering abstract see ITRD E116488.
