To provide a road surface gradient detection device for a vehicle capable of highly accurately calculating the gradient of a road surface on which the vehicle is traveling.SOLUTION: A road surface gradient detection device for a vehicle Ve comprises: a positional information acquisition unit configured to detect a current position of the vehicle Ve; a move distance calculation unit configured to calculate, on the basis of the current position of the vehicle Ve, a move distance L_gps in a horizontal direction when the vehicle Ve travels from a predetermined first point to a predetermined second point; a move distance calculation unit configured to calculate a travel distance L_vehivle which is a distance that the vehicle Ve has actually traveled from the first point to the second point; a road surface gradient calculation unit configured to calculate a gradient of a road surface, on the basis of the move distance L_gps and the travel distance L_vehivle; and an inclination direction determination unit configured to determine whether the road surface has an upward gradient or a downward gradient, on the basis of a required acceleration and an actual acceleration when the vehicle Ve travels from the first point to the second point.SELECTED DRAWING: Figure 3

    【課題】走行している路面の勾配を高い精度で算出することが可能な車両の路面勾配検出装置を提供する。【解決手段】車両Veの路面勾配検出装置であって、車両Veの現在位置を検出する位置情報取得部と、車両Veの現在位置に基づき車両Veが所定の第1地点から所定の第2地点まで走行したときの車両Veの水平方向における移動距離L_gpsを算出する移動距離算出部と、車両Veが第1地点から第2地点まで実際に走行した距離である走行距離L_vehivleを算出する走行距離算出部と、移動距離L_gpsと走行距離L_vehivleとに基づいて路面の勾配を算出する路面勾配算出部と、車両Veが第1地点から第2地点まで走行したときの要求加速度と実加速度とに基づいて、路面が上り勾配であるか下り勾配であるかを判定する傾斜方向判定部と、を備えている。【選択図】図3
