PROBLEM TO BE SOLVED: To suppress notification of a speed limit higher than an actual speed limit when erroneous recognition of a speed limit is caused.SOLUTION: A driving support device recognizes a speed limit of a travel lane being a lane on which a subject vehicle travels, based on a photographed image around the subject vehicle and performs notification of a recognized result (hereinafter referred to as recognized speed) (S210). Further, when a lane change is detected (S215), whether erroneous recognition of the speed limit is caused after the lane change is determined based on a result obtained by comparing a recognized speed during traveling on a travel lane after the lane change with a recognized speed during traveling on a travel lane just before the lane change and a positional relationship between the travel lanes (S225 and S240). When the erroneous recognition is caused, then the notification of a recognized speed is performed based on a predetermined mode (S230 and S245).SELECTED DRAWING: Figure 4

    【課題】制限速度の誤認識が生じた際に、実際の制限速度よりも高い制限速度を報知することを抑制する。【解決手段】運転支援装置は、自車両周辺の撮影画像に基づき、自車両が走行中の車線である走行車線の制限速度を認識し、認識結果(以後、認識速度)を報知する(S210)。一方、車線変更を検出すると(S215)、車線変更後の走行車線の走行中の認識速度と、該車線変更の直前の走行車線の走行中の認識速度との比較結果、及び、これらの走行車線の位置的な関係性に基づき、該車線変更後に制限速度の誤認識が生じたか否かを判定する(S225,S240)。そして、誤認識が生じた場合、予め定められた態様で認識速度を報知する(S230,S245)。【選択図】図4
