To improve accuracy of determining whether lane departure prevention processing can be operated.SOLUTION: A lane departure prevention system 1 includes: an operability determination unit 8 that determines based on a yaw angle θ of a vehicle 2 to a traveling lane TL in which the vehicle 2 travels whether lane departure prevention processing to prevent a departure of the vehicle 2 from the traveling lane TL can be operated; and a vehicle body slip angle acquisition unit 7 that acquires a vehicle body slip angle β of the vehicle body 2. The operability determination unit 8 determines whether the lane departure prevention processing can be operated by subtracting the vehicle body slip angle β from the yaw angle θ.SELECTED DRAWING: Figure 1
【課題】車線逸脱抑制処理の作動可否の判定精度を向上する。【解決手段】車線逸脱抑制装置1は、車両2が走行する走行車線TLに対する車両2のヨー角θに基づいて、走行車線TLからの車両2の逸脱を抑制する車線逸脱抑制処理の作動可否を判定する作動可否判定部8と、車両2の車体スリップ角βを取得する車体スリップ角取得部7と、を備え、作動可否判定部8は、ヨー角θから車体スリップ角β分を減算して、車線逸脱抑制処理の作動可否を判定する。【選択図】図1
