To provide a lane deviation suppression device which improves practicability.SOLUTION: A DSECU executes lane deviation warning of actuating a vibration device and steering support of controlling a motor for steering so as to prevent deviation of own vehicle from the lane when detecting that the own vehicle is deviated from a central part to an end side in a lane traverse direction by a predetermined distance or more, and degenerates the form of the steering support or prohibits the steering support when a steering torque TR is equal to a threshold TRth or more. The DSECU degenerates the form of the steering support or prohibits the steering support when the steering torque TR is equal to a first torque T1 or more, in the state of not executing the lane deviation warning, and degenerates the form of the steering support or prohibits the steering support when the steering torque TR is equal to or more than a second torque T2 larger than the first torque T1, in the state of executing the lane deviation warning.SELECTED DRAWING: Figure 4

    【課題】実用性を向上させた車線逸脱抑制装置を提供する。【解決手段】自車両が車線の横断方向における中央部から端部側へ所定の距離以上逸脱していることを検出したとき、振動装置を作動させる車線逸脱警告と、自車両が前記車線を逸脱しないように操舵用モータを制御する操舵支援と、を実行するDSECUであって、操舵トルクTRが閾値TRth以上であるとき、前記操舵支援の態様を縮退又は前記操舵支援を禁止する。DSECUは、前記車線逸脱警告を実行していない状態において、操舵トルクTRが、所定の第1トルクT1以上である場合に前記操舵支援の態様を縮退又は前記操舵支援を禁止し、前記車線逸脱警告を実行している状態において、操舵トルクTRが、第1トルクT1より大きい第2トルクT2以上である場合に前記操舵支援の態様を縮退又は前記操舵支援を禁止する。【選択図】図4
