To provide a safety driving assistance device that enables a driver to drive without anxiety when an obstacle or the like which cannot be recognized from the own vehicle is present ahead of a curve without a sudden approach to a vehicle ahead.SOLUTION: A safety driving assistance device 1 comprises: an inter-vehicle distance detection unit 30 that detects an inter-vehicle distance LS between a preceding vehicle SV traveling in front of an own vehicle MV and the own vehicle MV; a preceding vehicle speed detection unit 50 that detects a traveling speed VSV of the preceding vehicle SV; a preceding vehicle deceleration detection unit 60 that detects a deceleration GSV of the preceding vehicle SV on the basis of the traveling speed VSV of the preceding vehicle SV; an assumed deceleration calculation unit 90 that calculates an assumed deceleration Gt when the preceding vehicle SV goes into a curve on the basis of the inter-vehicle distance LS, the traveling speed VSV of the preceding vehicle SV, a current position of the own vehicle MV, and information on the curve acquired from map information; and a vehicle control unit 110 that performs control for reducing the traveling speed of the own vehicle MV in the case where the deceleration GSV is larger than the assumed deceleration Gt.SELECTED DRAWING: Figure 1

    【課題】カーブの先に自車両から確認できない障害物等があったときに、先行車両に急接近することなく、運転者が安心して走行することができる安全運転支援装置を提供する。【解決手段】安全運転支援装置1は、自車両MVの前方を走行する先行車両SVと自車両MVとの車間距離LSを検出する車間距離検出部30と、先行車両SVの走行速度VSVを検出する先行車両速度検出部50と、先行車両SVの走行速度VSVに基づいて、先行車両SVの減速度GSVを検出する先行車両減速度検出部60と、車間距離LSと、先行車両SVの走行速度VSVと、自車両MVの現在位置と、地図情報から取得したカーブの情報とに基づいて、先行車両SVがカーブに進入するときの想定減速度Gtを算出する想定減速度算出部90と、減速度GSVが想定減速度Gtよりも大きい場合には、自車両MVの走行速度を減速させる制御を行う車両制御部110とを備えている。【選択図】図1
