To appropriately execute detection of foreign matter adhesion to an object detection sensor.SOLUTION: An adhesion detection device (30) is constituted so as to detect foreign matter adhesion to an object detection sensor. The adhesion detection device comprises an adhesion determination unit (305), an accelerating/decelerating state acquisition unit (303), and a threshold setting unit (304). The adhesion determination unit determines foreign matter adhesion to the object detection sensor, when a count value exceeds an adhesion determination value, the count value corresponding to a duration time in a proximity detection state where a proximity state of the object detection sensor approaching an object approach is detected. The accelerating/decelerating state acquisition unit acquires an accelerating/decelerating state of a vehicle. The threshold setting unit sets the adhesion determination value according to the accelerating/decelerating state acquired by the accelerating/decelerating state acquisition unit.SELECTED DRAWING: Figure 3
【課題】物体検知センサに対する異物の付着検知をより適切に実行すること。【解決手段】付着検知装置(30)は、物体検知センサに対する異物の付着を検知するように構成されている。この付着検知装置は、付着判定部(305)と、加減速状態取得部(303)と、閾値設定部(304)とを備えている。前記付着判定部は、前記物体検知センサと前記物体とが近接する近接状態が検知されている近接検知状態の継続時間に対応する計数値が付着判定閾値を超えた場合に、前記物体検知センサに対する前記異物の付着を判定する。前記加減速状態取得部は、車両の加減速状態を取得する。前記閾値設定部は、前記加減速状態取得部によって取得された前記加減速状態に応じて前記付着判定閾値を設定する。【選択図】図3
