PROBLEM TO BE SOLVED: To allow a driver to continuously drive with a stable steering feeling when a vehicle runs on a curve.SOLUTION: A lane keeping supporting device 1 includes: a positional information acquisition section 31 which acquires information indicating a position of a vehicle; a speed detection section 33 which detects a speed of the vehicle; a curve position acquisition section 32 which acquires a start position of a first curve that exists in the front in a travel direction of the vehicle, is the closest from the position of the vehicle, and has a radius of curvature of a first value or less and an end position of a second curve that exists between the position of the vehicle and the start position of the first curve, is the closest to the start position of the first curve, and has a radius of curvature equal to or larger than a second value larger than the first value, from map data; a location determination section 34 which determines a location where the vehicle can reach the end position of the second curve in a predetermined time from the end position of the second curve and the speed of the vehicle; and a supporting force instruction section 35 which gives an instruction for reducing lane keeping support to the steering supporting section 4 which supports the vehicle so that the vehicle runs while keeping the lane when reaching the location determined by the location determination section 34.SELECTED DRAWING: Figure 2

    【課題】車両がカーブを走行している際に運転者が安定した操舵感で運転を継続できる。【解決手段】車線維持支援装置1は、車両の位置を示す情報を取得する位置情報取得部31と、車両の速度を検出する速度検出部33と、車両の進行方向前方に存在し且つ車両の位置から最も近い、曲率半径が第1の値以下の第1カーブの開始位置と、車両の位置と第1カーブの開始位置との間に存在し且つ第1カーブの開始位置から最も近い、曲率半径が第1の値よりも大きい第2の値以上の第2カーブの終了位置と、を地図データから取得するカーブ位置取得部32と、第2カーブの終了位置と車両の速度とから、所定の時間で車両が第2カーブの終了位置に到達できる地点を決定する地点決定部34と、車両が、地点決定部34が決定した地点に到達した際に、車両が車線を維持して走行することを補助する操舵補助部4に、車線維持支援を低減する指示を出す補助力指示部35と、を備える。【選択図】図2
