To solve the problem that, even though an attempt to roughly grasp the condition of a road surface in contact with tires of a vehicle by detecting the condition of a road surface on the sides of the vehicle is useful as it may be slippery when getting off the vehicle if the road surface on the sides of the vehicle is wet or frozen and requires caution, attempting to detect the road condition by irradiating the sides of the vehicle with light may be bothersome to a driver and people around the vehicle.SOLUTION: The road surface condition is detected by projecting an image of visible light onto a road surface below the side of a vehicle and receiving reflected light of the projected image.SELECTED DRAWING: Figure 1

    【課題】車両側方の路面が濡れていたり凍結していたりすると、車から人が降りる際に滑りやすく、注意を要することがある。また、車両の側方の路面状態を検出すれば、車両のタイヤが接する路面状態もおおよそ把握することができる。しかし、車両の側方に光を照射して路面状態を検知しようとするとドライバーや車両の周囲の人に違和感を与える可能性がある。【解決手段】 車両の側方下部の路面に可視光により画像を投影して、投影された画像の反射光を受光し、路面状態を検出する。【選択図】 図1
