To provide a vehicle vibration-damping control apparatus which performs preview control.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 and a vehicle body; and a control unit which controls the control force generation device to change the control force. The control unit acquires, as sampling values, road surface displacement related values which are values related to a plurality of road surface displacements included in a predetermined sampling section ahead of the ground position of the wheel at a present point of time, calculates an amplitude index value indicating the magnitude of the amplitude of the road surface displacements in the sampling section on the basis of the sampling values, determines an operation delay time in the control force generation device on the basis of the magnitude of the amplitude indicated by the amplitude index value, calculates target control force for reducing the vibration of the vehicle body on the basis of the road surface displacement related values at a predicted passing position where the wheel is predicted to pass after the operation delay time from the present point of time, and transmits, to the control force generation device, a control command for causing the control force generation device to make the control force agree with the target control force.SELECTED DRAWING: Figure 10

    【課題】プレビュー制御装置を行う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、少なくとも一つの車輪と車体との間に上下方向の制御力を発生するように構成された制御力発生装置と、制御力発生装置を制御して制御力を変更する制御ユニットを備える。制御ユニットは、車輪の現時点の接地位置よりも前方の所定のサンプリング区間に含まれる複数の路面変位に関連した値である路面変位関連値をサンプリング値とし、サンプリング値に基いて、車両がサンプリング区間の路面変位の振幅の大きさを表す振幅指標値を演算し、振幅指標値が表す振幅の大きさに基いて、制御力発生装置の作動遅れ時間を決定し、車輪が現時点から作動遅れ時間後に通過すると予測される通過予測位置の路面変位関連値に基いて、車体の振動を低減するための目標制御力を演算し、制御力発生装置が制御力を目標制御力と一致させるための制御指令を制御力発生装置に送信する。【選択図】図10
