To provide a drive assistance device that can improve safety when an own vehicle turns to left or right.SOLUTION: A drive assistance device comprises: a front sensor that acquires information related to a traffic participant present in predetermined regions on a left front and a right front of an own vehicle; an alarm device configured to execute an alarm to an occupant in the own vehicle; and a processor configured to control the alarm device. If an intention to turn, which is a driver's intention to turn the own vehicle to the side on which the traffic participant exists, is detected within a predetermined time from a first point at which the front sensor could no longer detect the traffic participant as a result the traffic participant deviated from the region due to approach of the own vehicle to the traffic participant, the processor predicts the distance between the traffic participant and the own vehicle in front-back direction at a second point at which the intention to turn was detected. If the predicted distance between the traffic participant and the own vehicle in front-back direction is within a predetermined range, the processor makes the alarm device execute an alarm.SELECTED DRAWING: Figure 3
【課題】自車両が左折又は右折する際の安全性を向上させることができる運転支援装置の提供。【解決手段】運転支援装置は、自車両の左前方及び右前方の所定の領域内に存在する交通参加者に関する情報を取得する前方センサと、自車両の乗員に対して警報を実行することができるように構成された警報装置と、警報装置を制御することができるように構成されたプロセッサと、を備える。プロセッサは、交通参加者に自車両が接近して交通参加者が領域から逸脱することにより前方センサが交通参加者を検知できなくなった第一時点から所定時間以内に、交通参加者が存在する側へ自車両を旋回させる運転者の意図である旋回意図を検知した場合に、旋回意図を検知した第二時点における交通参加者と自車両との前後方向の距離を予測し、予測した交通参加者と自車両との前後方向の距離が、所定の範囲内にある場合に、警報装置に警報を実行させる。【選択図】図3
