ABSTRACT:
An active suspension system and an active suspension control method for a vehicle having a first wheel set and a second wheel set, comprising a power actuator interposed between the vehicle body and each of the wheels; a sensor for detecting turning maneuver of the vehicle; and a control unit for controlling operation of the actuators according to data obtained from the sensor so as to reduce a vertical load acting on the inner wheel of the second wheel set which bears a less vertical load than the first wheel set during the turning maneuver. Thereby, the shifting of the vertical load between the wheels of the first wheel set is reduced with the result that the overall cornering force of the vehicle is maximized because of the saturating property of the maximum cornering force of the tire in relation with the vertical load acting thereon.
