To provide a lane deviation prevention device for reducing the risk of feeling inconvenience in lane deviation prevention control when lane deviation is performed by driving based on a driver's intention.SOLUTION: A lane deviation prevention device performs lane deviation prevention control when a vehicle has the risk of deviating from a lane, but does not perform the lane deviation prevention control when an index value indicating the strength of a lane deviation intention in a driver is equal to or more than a reference value regardless of the risk that the vehicle may deviate from the lane. When an obstacle is not detected ahead of a travel direction of the vehicle and also a visual line direction of the driver is the same as a direction in which the vehicle may deviate from the lane (S160), and when the obstacle is detected (S120), the reference value is reduced (S180) compared with a case where the obstacle is not detected and also when the visual line direction of the driver is not the same as the direction in which the vehicle may deviate from the lane (S130).SELECTED DRAWING: Figure 3

    【課題】ドライバーの意思に基づく運転により車線逸脱する場合に、車線逸脱予防制御に煩わしさを覚える虞を低減する車線逸脱防止装置を提供する。【解決手段】車両が車線から逸脱する虞があるときには、車線逸脱予防制御を実行し、車両が車線から逸脱する虞があっても、ドライバーの車線逸脱の意図の強さを示す指標値が基準値以上であるときには、車線逸脱予防制御を実行しない車線逸脱防止装置であって、車両の進行方向前方に障害物が検出されておらず且つドライバーの視線の方向と車両が車線から逸脱する虞がある方向とが同一である場合(S160)、及び障害物が検出されている場合(S120)には、障害物が検出されておらず且つドライバーの視線の方向と車両が車線から逸脱する虞がある方向とが同一ではない場合(S130)に比して、基準値を低減する(S180)。【選択図】図3
