To provide a vehicle driving support device capable of predicting the possibility of collision and collision position in driving assistance when a vehicle is driving while turning.SOLUTION: The vehicle driving support device is configured to: calculate a yaw rate change rate based on a yaw rate of the own vehicle obtained at multiple times; predict a sequential position of the own vehicle as an own-vehicle position assuming that the yaw rate change rate is kept constant, and predict a sequential position of another vehicle as an other-vehicle position; determine the possibility of a collision depending on whether there is a collision position where the own-vehicle position partially overlaps with the other-vehicle position; and when determining that there is no possibility of collision until the end of the prediction as the point at which the own vehicle turns at a set angle, terminate the sequential prediction of the own-vehicle position and the other-vehicle position.SELECTED DRAWING: Figure 4
【課題】自車両が旋回して走行している場合の運転支援において、衝突位置の予測や衝突有無の判定は困難である。【解決手段】複数の時点で得た自車両のヨーレートからヨーレート変化率を算出し、前記ヨーレート変化率が一定に維持される前提で逐次の自車両の位置を自車位置として予測すると共に、逐次の他車両の位置を他車位置として予測し、逐次の前記自車位置が前記他車位置と部分的に重なる衝突位置の有無により、衝突の有無を判定し、自車両が設定角度に旋回する時点である予測終了時点まで衝突が無いと判定されると、逐次の前記自車位置と前記他車位置の予測を終了する。【選択図】 図4
