To effectively perform the vibration damping of a sprung structure.SOLUTION: A vehicular suspension control device includes: an actuator for applying controlling force in a vertical direction between an unsprung structure and a sprung structure; and an electronic control unit for controlling the actuator so that the controlling force is generated according to a required controlled variable required for reducing the vibration of the sprung structure. The required controlled variable includes at least two control terms of a displacement term, velocity term, and acceleration term related to the displacement, velocity, and acceleration of the sprung structure. The electronic control unit executes: calculation processing to calculate the magnitude of a frequency component of each of a plurality of frequency bands included in road surface vibration information; and gain determination processing to determine a control gain of each of the at least two control terms so that the control gain changes on the basis of the magnitude of the frequency component of each of the plurality of frequency bands.SELECTED DRAWING: Figure 3

    【課題】ばね上構造体の制振を効果的に行えるようにする。【解決手段】車両用サスペンション制御装置は、ばね下構造体とばね上構造体との間に上下方向の制御力を作用させるアクチュエータと、ばね上構造体の振動を低減するために要求される要求制御量に応じた制御力を発生させるようにアクチュエータを制御する電子制御ユニットと、を備える。要求制御量は、ばね上構造体の変位、速度、及び加速度に関する変位項、速度項、及び加速度項のうちの少なくとも2つの制御項を含む。電子制御ユニットは、路面振動情報に含まれる複数の周波数帯のそれぞれの周波数成分の大きさを算出する算出処理と、複数の周波数帯のそれぞれの周波数成分の大きさに基づいて変化するように少なくとも2つの制御項のそれぞれの制御ゲインを決定するゲイン決定処理と、を実行する。【選択図】図3
