To provide an active suspension device and a suspension control device capable of preventing the risk of deterioration of riding comfort for a person riding in an automobile.SOLUTION: An ECU 4 is a control device for a damping force variable damper used for damping relative vibration between a vehicle body member 1 and a wheel 16, and comprises: a road surface height measuring unit 41 for measuring road surface heights at three or more positions on a road surface along a vehicle width direction ahead of a tire 15 provided on the wheel 16; a position detection unit 42 for detecting neighboring positions with a difference between road surface heights that is equal to or greater than a threshold value, among the road surface heights at the three or more positions measured by the road surface height measuring unit 41; and a road surface condition determination unit 44 for determining a condition of the road surface on the basis of neighboring road surface heights whose difference is less than the predetermined threshold, excluding values of the road surface heights each of whose differences is equal to or greater than the predetermined threshold value, according to the detected results of the position detection unit 42.SELECTED DRAWING: Figure 3
【課題】自動車に乗っている人の乗り心地が悪くなる恐れを防止することができる、アクティブサスペンション装置、及びサスペンションの制御装置を提供する。【解決手段】ECU4は、車体部材1と車輪16との間の相対振動の減衰に供される減衰力可変ダンパの制御装置であって、車輪16に設けられたタイヤ15の前方の車幅方向に沿って、3点以上の路面の高さを計測する路面高さ計測部41と、路面高さ計測部41が計測した3点以上の路面の高さのうち、隣り合う路面の高さの差分が所定の閾値以上となる位置を検出する位置検出部42と、位置検出部42が検出した、差分が所定の閾値以上となる位置の路面の高さの値を除外して、隣り合う路面の高さの差分が所定の閾値未満の路面の高さに基づいて、路面の状態を判定する路面状態判定部44と、を備える。【選択図】図3
