To effectively reflect the driver's intention while effectively reducing the risk of collision.SOLUTION: A controller of a lane deviation prevention device comprises: a lane deviation detection part 130 that detects lane deviation; a succeeding vehicle determination part 110 that determines whether or not there is a succeeding vehicle; a lane change start detection part 140 that detects start of lane change; a lane change completion detection part 150 that detects completion of the lane change; a steering auxiliary control part 160 that applies auxiliary steering torque to a steering wheel 21 in a direction opposite to a lane deviation direction for a predetermined period so as to maintain an own vehicle to travel within a current traveling lane when the lane deviation is detected; and auxiliary steering torque release parts 170 and 180, the former releasing the application of the auxiliary steering torque when the start of the lane change is detected without the presence of any succeeding vehicle, meanwhile the latter releasing the application of the auxiliary steering torque when the completion of the lane change is detected with the presence of the succeeding vehicle.SELECTED DRAWING: Figure 4
【課題】衝突の危険性を効果的に低減しつつ、運転者の意図を効果的に反映する。【解決手段】車線逸脱を検出する車線逸脱検出部130と、後方車両がいるか否かを判定する後方車両判定部110と、車線変更開始を検出する車線変更開始検出部140と、車線変更完了を検出する車線変更完了検出部150と、車線逸脱が検出されると、走行車線を維持するように、ステアリングホイール21に対して車線逸脱方向とは逆向きの補助操舵トルクを所定期間に亘って付与する操舵補助制御部160と、後方車両がいない場合において、車線変更開始を検出すると、補助操舵トルクの付与を解除する一方、後方車両がいる場合において、車線変更完了を検出すると、補助操舵トルクの付与を解除する補助操舵トルク解除部170,180とを備えた。【選択図】図4
