To enable the preview control of an active suspension D on the basis of a road surface displacement detected by a preview road surface detection device 1, even when a tire is deformed at the time of turning of a vehicle, or the like.SOLUTION: A preview road surface detection device 1 includes: a distance sensor 11 provided on a vehicle body member 3, for detecting a distance to a measurement point on a road surface in front of a vehicle, corresponding to at least the central part of the road surface contact part of a wheel W; and a distance calculation section 12 for calculating a road surface distance from the vehicle body member 3 to the measurement point, on the basis of a value detected by the distance sensor 11. A road surface displacement in front of the vehicle is calculated from the road surface distance and the vehicle height of the vehicle body member 3 when the distance is detected by the distance sensor 11. The road surface displacement is detected as a road surface condition.SELECTED DRAWING: Figure 1
【課題】車両の旋回時などでタイヤが変形している場合でも、プレビュー路面検出装置1で検出した路面変位に基づいてアクティブサスペンションDが予見制御されるようにする。【解決手段】本発明のプレビュー路面検出装置1は、車体部材3に設けられ、車輪Wの路面接地部の少なくとも中央部に対応する車両前方の路面の測定点との距離を検出する距離センサ11と、距離センサ11の検出値に基づいて車体部材3から測定点までの路面距離を算出する距離算出部12と、を備え、路面距離と距離センサ11で距離を検出した際の車体部材3の車高とから算出した車両前方の路面変位を路面状態として検出するようにした。【選択図】図1
