To provide a road surface crossing slope detection device that can prevent a crossing slope amount of a road surface from being detected as a value greatly deviated from a real crossing slope amount when a vehicle straight-traveling the road with irregularities existing on the road surface.SOLUTION: A road surface crossing slope detection device includes: multiple marks 18a, 18b applied to an inner face of a target tire 15b being at least one wheel of a vehicle and being a tire of a target wheel; straight traveling determination means for determining whether or not the vehicle straight-travels on the road surface of the road grounded by the target tire; a camera 17 provided at the target wheel and imaging each mark; irregularity determination means for determining whether or not irregularities are present on the road surface, based on the imaging data of the camera; and crossing slope amount calculation means for calculating a crossing slope amount of the road surface, based on the imaging data of the camera, when the straight traveling determination means determines that the vehicle straight-travels and the irregularity determination means determines that the irregularities are not present on the road surface.SELECTED DRAWING: Figure 2
【課題】路面に凹凸が存在する道路上を車両が直進走行している場合に、この路面の横断勾配量を実際の横断勾配量から大きく乖離した値として検出することを防止できる路面横断勾配検出装置を提供するる【解決手段】車両の少なくとも一つの車輪である対象車輪のタイヤである対象タイヤ15bの内面に付された複数のマーク18a,18bと、対象タイヤが接地している道路の路面上を車両が直進走行しているか否かを判定する直進走行判定手段と、対象車輪に設けられ且つ各マークを撮像するカメラ17と、カメラの撮像データに基づいて、路面に凹凸が有るか否かを判定する凹凸判定手段と、直進走行判定手段が車両が直進走行していると判定し且つ凹凸判定手段が路面に凹凸が無いと判定したときに、カメラの撮像データに基づいて路面の横断勾配量を演算する横断勾配量演算手段と、を備える。【選択図】図2
