To provide a preview road surface detection device capable of inhibiting detection waves transmitted from a plurality of transmitters from being received while being confused.SOLUTION: A preview road surface detection device comprises: a distance sensor which comprises a plurality of transmitters and at least one receiver mounted on a vehicle body member so as to be arranged in a direction intersecting a vehicle travel direction, and which detects a value related to a distance between the vehicle body member and a measurement point on a road surface ahead of a vehicle and corresponding to at least part of a road surface contact part of a wheel; and a distance calculation section which calculates a road surface distance, as the distance from the vehicle body member to the measurement point, on the basis of the detection value detected by the distance sensor. Each transmitter transmits a detection wave with a difference in time from the adjacent transmitter.SELECTED DRAWING: Figure 3 【課題】複数の発信機から発信された検出波が混同して受信されることを抑制することが可能なプレビュー路面検出装置を提供すること。【解決手段】車体部材に、車両の進行方向に対して交わる方向に向けて並んで取り付けられた、複数の発信機、及び少なくとも一つの受信機を備え、車体部材と、車輪の路面接地部の少なくとも一部に対応する車両前方の路面の計測点と、の間の距離に関する値を検出する距離センサと、距離センサが検出した検出値に基づいて、車体部材から計測点までの距離である路面距離を算出する距離算出部と、を備え、発信機は、隣り合う発信機から時間差を有して検出波を発信する、プレビュー路面検出装置。【選択図】図３
