To provide a brake force imparting type lane deviation prevention device which is improved so as to reduce a possibility that an occupant of a vehicle feels incongruity caused by deceleration of the vehicle.SOLUTION: A lane deviation prevention device includes a drive support ECU configured to impart a yaw moment reducing a possibility that a vehicle deviates from a lane to the vehicle by imparting brake force to a wheel opposite to a side where the vehicle deviates from the lane (S60 and S70), when determining that there is the possibility that the vehicle deviates from the lane on the basis of information acquired by a target information acquisition device (S10), wherein the drive support ECU imparts the brake force to the vehicle opposite to the side where the vehicle deviates from the lane when determining that an encountering target when the vehicle deviates from the lane is not a three-dimensional object (S40), imparts drive force to the wheel on the side where the vehicle deviates from the lane (S80 to S140), and imparts a yaw moment reducing the possibility to the vehicle.SELECTED DRAWING: Figure 3

    【課題】車両の減速に起因して車両の乗員が違和感を覚える虞が低減されるよう改良された制動力付与式の車線逸脱防止装置を提供する。【解決手段】物標情報取得装置により取得された情報に基づいて車両が車線を逸脱する虞があると判定したときには(S10)、車両が車線を逸脱する側とは反対側の車輪に制動力を付与する(S60、S70)ことにより、上記虞を低減するヨーモーメントを車両に付与するよう構成された運転支援ECUを含む車線逸脱防止装置であって、運転支援ECUは、車両が車線を逸脱したときに遭遇する物標が立体物ではないと判定したときには(S40)、車両が車線を逸脱する側とは反対側の車輪に制動力を付与すると共に、車両が車線を逸脱する側の車輪に駆動力を付与して(S80~S140)、上記虞を低減するヨーモーメントを車両に付与する。【選択図】図3
