To provide a vehicle driving support device capable of solving a problem in conventional collision determination devices, that is, although a collision detection function is valid when own vehicle is traveling straight and invalid when the own vehicle is traveling around a curve.SOLUTION: The vehicle driving support device is configured to: calculate a predicted trajectory of the own vehicle in a circle with a radius obtained from the own vehicle's yaw rate at the prediction reference point; calculate a predicted trajectory of another vehicle based on data from the other vehicles at the prediction reference point; calculate tentative collision point based on the intersection of the predicted trajectory of the own vehicle and the predicted trajectory of the other vehicle; calculate the tentative collision point at which the own vehicle reaches the tentative collision point; and determine the possibility of a collision, assuming that the own vehicle and the other vehicle at the time of the tentative collision travel straight to cross each other.SELECTED DRAWING: Figure 2
【課題】従来の衝突判定装置は、自車両が直進している場合に有効である。しかし、自車両がカーブして走行している場合には衝突判定が機能しにくい。【解決手段】予測基準時点における自車両のヨーレートから得た半径の円の自車予測軌跡を算出し、前記予測基準時点における他車両のデータから他車予測軌跡を算出し、前記自車予測軌跡と前記他車予測軌跡との交点から仮衝突点を算出して、前記自車両が前記仮衝突点に至る仮衝突時点を算出し、前記仮衝突時点の前記自車両と前記他車両が直進するとして、直進交差により衝突有無の判定を行う。【選択図】 図2
