Abstract:
1. A suspension system for a vehicle, comprising: a roll control device, which includes an actuator, for controlling roll of a vehicle body by an actuation of the actuator; a control device including wherein the target control value determining portion determines the target control value of the actuator on the basis of the estimated lateral acceleration when degree of the actual lateral acceleration is smaller than a predetermined threshold; and by weighting the estimated lateral acceleration to gradually decrease from one to zero and by weighting the actual lateral acceleration to gradually increase from zero to one in accordance with an increase of the actual lateral acceleration from the predetermined threshold when the degree of the actual lateral acceleration is greater than the predetermined threshold, the target control value determining portion determines the target control value of the actuator on the basis of sum of the weighted estimated lateral acceleration and the weighted actual lateral acceleration; and wherein the control device further includes a slip judging portion judging whether degree of a slip of vehicle is excessive, and a second target control value determining portion for determining target control value of the actuator on the basis of the actual lateral acceleration irrespective of degree of the actual lateral acceleration in place of determination by the target control value determining portion when the slip judging portion judges that a slip of the vehicle is excessive.
