To provide a lane deviation prevention device capable of reducing the possibility of letting a driver feel annoyance about an alarm for informing the driver that the vehicle is likely to deviate from a lane.SOLUTION: A lane deviation prevention device 10 executes automatic steering control for performing automatic steering to automatically apply a steering force to an own vehicle 100 to return the own vehicle to a lane in the case that a vehicle deviation condition is satisfied. The lane deviation prevention device also executes alarm control for notifying the driver of the own vehicle that the host vehicle is likely to deviate from the lane when it is determined on the basis of an actual travel state of the own vehicle that an alarm execution condition is satisfied in the case that the automatic steering control is not executed. Meanwhile, the lane deviation prevention device executes alarm control when it is determined on the basis of the travel state of the own vehicle which is realized by the automatic steering control that the alarm execution condition is satisfied in the case that the automatic steering control is executed.SELECTED DRAWING: Figure 8

    【課題】自車両が車線から逸脱する可能性があることを運転者に知らせるための警報に対する煩わしさを運転者に感じさせてしまうことを低減することができる車線逸脱防止装置を提供する。【解決手段】車線逸脱防止装置10は、自動操舵実行条件が成立した場合、自車両100に自動で操舵力を与えて自車両を車線に戻す自動操舵を行う自動操舵制御を実行する。又、車線逸脱防止装置は、自動操舵制御を実行していない場合、自車両の実際の走行状態に基づいて警報実行条件が成立したと判定したときに、自車両が車線から逸脱する可能性があることを自車両の運転者に知らせるための警報を行う警報制御を実行する。一方、車線逸脱防止装置は、自動操舵制御を実行している場合、自動操舵制御により実現される自車両の走行状態に基づいて警報実行条件が成立したと判定したときに、警報制御を実行する。【選択図】 図8
