PROBLEM TO BE SOLVED: To gradually change the attitude of a vehicle more quickly than with conventional techniques, thereby improving the comfort of riding in the vehicle, in a situation where the inclination angle of a road surface greatly changes upward ahead of the vehicle.SOLUTION: A suspension control apparatus includes a preview sensor and a control device for estimating an inclination angle φ of a road surface on the basis of a result of detection by the preview sensor and controlling an active suspension. In the case of determining that a change amount of an upward inclination angle of a road surface within a given zone is equal to or higher than a reference value (S30, S40), the control device sets a guide line whose inclination angle changes more quickly and gradually than a change in the inclination angle of the road surface (S50) and controls vehicular heights at front and rear wheels through active suspension control so that the center of gravity G of the vehicle moves along the guide line, with a longitudinal direction of the vehicle in line with a direction of a tangential line relative to the guide line at the center of gravity G (S60).SELECTED DRAWING: Figure 3

    【課題】車両前方における路面の傾斜角が上り方向へ大きく変化する状況において、車両の姿勢を従来に比して早くから穏やかに変化させることにより、車両の乗り心地性を向上させる。【解決手段】プレビューセンサと、プレビューセンサの検出結果に基づいて路面の傾斜角φを推定し、アクティブサスペンションを制御する制御装置と、を有するサスペンション制御装置。制御装置は、所定の範囲内における路面の傾斜角の上り方向への変化量が基準値以上であると判定したときには(S30、40)、傾斜角が路面の傾斜角の変化よりも早く且つ穏やかに変化する案内線を設定し(S50)、車両の重心Gが案内線に沿って移動し且つ車両の前後方向が重心Gにおける案内線に対する接線の方向に向くように、アクティブサスペンションの制御によって前輪及び後輪の車高を制御する(S60)。【選択図】図3
