To suppress deterioration of a damping effect caused by the influence of steps existing in a road surface data map.SOLUTION: A vehicle suspension control device includes an actuator for controlling a suspension stroke, and an electronic control unit (ECU). The ECU performs: acquisition processing of acquiring front road surface data, which is data of road surface displacement-related values on a front road surface including a predicted passing position, from a road surface data map mapped with the road surface displacement-related values being associated with data stored positions; determination processing of determining whether or not a vehicle is traveling so as to continuously use the road surface displacement-related values located at the boundaries of steps of the road surface displacement-related values existing in the front road surface data; filtering processing for applying a low-pass filter to the front road surface data if the determination result is affirmative; and control processing for executing preview damping control based on the front road surface data after the filtering processing if the determination result is affirmative.SELECTED DRAWING: Figure 11

    【課題】路面データマップ上に存在する段差の影響に起因する制振効果の低下等を抑制する。【解決手段】車両用サスペンション制御装置は、サスペンションストロークを制御するアクチュエータと、電子制御ユニット(ECU)とを備える。ECUは、路面変位関連値をデータ記憶位置と関連付けてマップ化した路面データマップから、予測通過位置を含む前方路面における路面変位関連値のデータである前方路面データを取得する取得処理と、前方路面データ上に存在する路面変位関連値の段差の境目に位置する路面変位関連値を連続的に使用するように車両が走行しているか否かを判定する判定処理と、この判定結果が肯定的である場合、前方路面データに対してローパスフィルタを適用するフィルタリング処理と、上記判定結果が肯定的である場合、フィルタリング処理後の前方路面データに基づいてプレビュー制振制御を実行する制御処理と、を実行する。【選択図】図11
