PROBLEM TO BE SOLVED: To provide a drive support device which can precisely specify distance which can be actually secured between an own vehicle and obstacle, and make the precise distance between the own vehicle and obstacle which cannot be easily understood in a bird's eye view image, understandable.SOLUTION: A drive support device comprises: an obstacle shape specification part 16 for specifying a shape expanding in a horizontal direction on each height position of an obstacle, based on a measurement result of a laser radar unit 6, acquired by a measurement result acquisition part 15; and an inter shortest portion distance specification part 18 for specifying inter shortest portion distance, in which distance between portions on a same height position of the own vehicle and obstacle becomes shortest, based on a shape extending in a horizontal direction on each height position of the own vehicle specified by own vehicle shape information stored in an own vehicle shape storage part 17, and the shape expanding in the horizontal direction of the obstacle on each height position, specified in the obstacle shape specification part 16. A display processing part 19 displays a marker on a position corresponding to the inter shortest portion distance in a direction where the obstacle exists to an own vehicle image.SELECTED DRAWING: Figure 1
【課題】自車と障害物との間で実際に確保できる距離をより正確に特定して、鳥瞰画像上ではわかりづらい自車と障害物とのより正確な距離をわかりやすくする運転支援装置を提供する。【解決手段】測定結果取得部15で取得した、レーザレーダユニット6での測定結果をもとに、障害物の高さ位置別の水平方向に広がる形状を特定する障害物形状特定部16と、自車形状記憶部17に記憶している自車形状情報から特定できる自車の高さ位置別の水平方向に広がる形状と、障害物形状特定部16で特定した障害物の高さ位置別の水平方向に広がる形状とをもとに、自車と障害物との同じ高さ位置にある部位間の距離が最も短くなる最短部位間距離を特定する最短部位間距離特定部18とを備え、表示処理部19は、自車画像に対して障害物が位置する方向の最短部位間距離に応じた位置にマーカを表示させる。【選択図】図1
