To make it possible to easily detect a change of a stationery situation such as a change of a road shape due to irregularity of a road surface, earth slide or snow accumulation so as not to give any burden to an operator.SOLUTION: A road surface determination device 10 of a vehicle 1 has: an irradiation device 2 which radiates pattern light toward a road surface 30 on which the vehicle 1 travels or a circumference of the vehicle 1; a detection device 18 which detects pattern light radiated onto the road surface 30; and a determination part 19 which determines a state of the road surface 30 based the detected pattern light. The irradiation device 2 performs irradiation intermittently and in a short time so that a period during which pattern light is not radiated becomes longer a period during which pattern light is radiated.SELECTED DRAWING: Figure 1

    【課題】運転者にわずらわしさを与えないように、路面の凹凸や土砂崩れや積雪による道路形状の変化などの静止的な状況の変化を容易に検出できるようにする。【解決手段】自動車1の路面判定装置10は、自動車1が走行する路面30または自動車1の周囲へ向けてパターン光を照射する照射装置2と、路面30に照射されたパターン光を検出する検出装置18と、検出されたパターン光に基づいて路面30の状態を判定する判定部19と、を有する。照射装置2は、パターン光を照射する期間より、パターン光を照射しない期間を長くするように間欠的に短時間で照射する。【選択図】図1
