PROBLEM TO BE SOLVED: To provide a drive assisting device that is able to appropriately caution a driver for an obstacle highly likely to collide with the own vehicle, taking account of a distance between the prediction travel route of the own vehicle and the obstacle.SOLUTION: A cautioning ECU 10 extracts an obstacle on the basis of a travel prediction route predicted on the basis of target information from a camera sensor 11 and a radar sensor 12 as well as information acquired by a vehicle state sensor 13 and calculates allowance time TTC as one of degrees of need for caution for the obstacle. The caution ECU calculates a distance between the obstacle and the travel prediction route, and makes a correction such that the shorter the distance is, the shorter the allowance time TTC is. The caution ECU selects, as an obstacle to be avoided, the obstacle in a case where the allowance time TTC after the correction is shortest. If the allowance time TTC for the obstacle to be avoided is equal to a threshold T1th, the caution ECU displays an image screen for guiding a line of sight of a driver toward a direction of the obstacle to be avoided.SELECTED DRAWING: Figure 4
【課題】自車両の予測走行進路と障害物との距離を考慮して、自車両に衝突する可能性が高い障害物に対して適切にドライバーの注意を喚起させることができる運転支援装置を提供すること。【解決手段】注意喚起ECU10は、カメラセンサ11及びレーダーセンサ12から物標情報及び車両状態センサ13により取得された情報に基づいて予測される走行予測進路に基づいて、障害物を抽出し、障害物の注意喚起必要度合の一つとして余裕時間TTCを算出する。注意喚起ECUは、障害物と走行予測進路との距離を算出し、当該距離が小さいほど、余裕時間TTCが小さくなるように補正し、補正後の余裕時間TTCが最小の障害物を処理対象障害物として選択し、当該処理対象障害物の余裕時間TTCが閾値T1th以下であれば、当該処理対象障害物の方向にドライバーの視線を誘導する画面を表示する。【選択図】図4
