To provide a vehicle travel support device which improves determination accuracy of situations of a road such as a position of a branch passage or a junction passage.SOLUTION: In a vehicle travel support device, a lane marker detection part 1 detects a lane marker on a road in the front of an own vehicle. A road situation determination part 2 calculates a first tilt change amount that is a change amount of a tilt of a tangent of the lane marker in a first position of the lane marker detected by the lane marker detection part 1 and a second tilt change amount that is a change amount of a tilt of a tangent of the lane marker in a second position of the lane marker, and determines the situation of the road based on a difference between the first inclination change amount and the second inclination change amount. A travel control part 3 determines a travel of the own vehicle based on the situation of the road determined by the road situation determination part 2.SELECTED DRAWING: Figure 1
【課題】車両走行支援装置において、分岐路または合流路の位置などの道路の状況の判断精度を向上させる。【解決手段】車両走行支援装置において、レーンマーカ検出部1は、自車前方の道路上のレーンマーカを検出する。道路状況判断部2は、レーンマーカ検出部1が検出したレーンマーカの第1の箇所におけるレーンマーカの接線の傾きの変化量である第1の傾き変化量と、レーンマーカの第2の箇所におけるレーンマーカの接線の傾きの変化量である第2の傾き変化量とを算出し、第1の傾き変化量と第2の傾き変化量との差に基づいて、道路の状況を判断する。走行制御部3は、道路状況判断部2が判断した道路の状況に基づいて、自車の走行を制御する。【選択図】図1
