To provide a vehicle vibration-damping control apparatus which can reliably reduce the component of suspension force corresponding to a value related to the vertical direction of a wheel at a predicted passing position even when actual suspension force becomes larger than theoretical suspension force.SOLUTION: A vehicle vibration-damping control apparatus includes: a control force generation device which generates control force in a vertical direction between at least one wheel suspended from a vehicle body by a suspension and the vehicle body; and a control unit which controls the control force generation device to change the control force. The control unit calculates an amplitude index value indicating the amplitude of road surface displacement related values in a predetermined sampling section including a predicted passing position where the wheel is predicted to pass at a point of time when a predetermined time elapses from a present time, determines a control gain so that target control force becomes larger as the amplitude indicated by the amplitude index value becomes smaller, and calculates the target control force on the basis of the road surface displacement related values at the predicted passing position and the control gain.SELECTED DRAWING: Figure 10

    【課題】実際のサスペンション力が理論サスペンション力よりも大きくなった場合でも、通過予測位置の車輪の上下方向に関連する値に対応するサスペンション力の成分を確実に低減できる車両の制振制御装置を提供する。【解決手段】車両の制振制御装置は、サスペンションにより車体から懸架された少なくとも一つの車輪と車体の間に上下方向の制御力を発生する制御力発生装置と、制御力発生装置を制御して制御力を変更するように構成された制御ユニットを備え、車輪が現時刻から所定時間が経過した時点にて通過すると予測される通過予測位置を含む所定のサンプリング区間における路面変位関連値の振幅を表す振幅指標値を演算し、振幅指標値によって表される振幅が小さいほど目標制御力が大きくなるように制御ゲインを決定し、通過予測位置の路面変位関連値と制御ゲインとに基いて目標制御力を演算する。【選択図】図10
