To provide an obstacle detector of a construction vehicle, that reduces costs and is easily set to a desired detection range according to a travel route of the vehicle.SOLUTION: An obstacle detector 1A mounted to a tire roller (construction vehicle) 10 includes: a distance image sensor (object detection sensor) 2 for detecting an obstacle within a predetermined range; and a controller which calculates an estimated travel route 21 of the tire roller 10 according to a turning radius of the tire roller 10, and determines presence/absence of an obstacle on the basis of a detection result of the distance image sensor 2. In the controller, a range corresponding to the estimated travel route 21 out of a projection range N1 of the distance image sensor 2, is set as a detection range 4A for detecting presence/absence of the obstacle.SELECTED DRAWING: Figure 7

    【課題】コストの低減を図れるとともに、車両の走行経路に応じて所望の検知範囲に容易に設定できる建設車両の障害物検知装置を提供する。【解決手段】タイヤローラ(建設車両)10に搭載される障害物検知装置1Aであって、所定範囲内における障害物を検知する距離画像センサ(物体検知センサ)2と、タイヤローラ10の回転半径に基づいてタイヤローラ10の推定走行経路21を算出するとともに、距離画像センサ2の検知結果に基づいて障害物の有無を判定する制御装置と、を備え、制御装置は、距離画像センサ2の投射範囲N1のうち推定走行経路21に対応する範囲が、前記障害物の有無を検知する検知範囲4Aとして設定されていることを特徴とする。【選択図】図7
