To provide a lane deviation preventing device which is improved so that a driver can smoothly perform a lane change for a second time when the driver changes a lane to an adjacent lane and then tries to continuously perform the lane change to an adjacent lane or a roadside strip.SOLUTION: In a lane deviation preventing device, when it is determined that there is a risk of a vehicle deviating from a lane (S20), the lane deviation preventing device performs a lane deviation prevention control (automatic steering of steered wheel and/or issuance of warning) (S50). When a control unit determines that an intention of a driver crossing a first white line to deviate from a lane changes from non-presence to presence (S30), the control unit cancels a lane departure prevention control until the control unit determines that a control return condition is established (S40 and S70). When the control unit determines that a speed Vy at which the vehicle is approaching a second white line at a destination of the vehicle is equal to or greater than a reference value Vyc (S100), the control unit continues to cancel the execution of the lane departure prevention control even if the control unit determines that the control return condition is established (S70).SELECTED DRAWING: Figure 2

    【課題】ドライバーが隣接する車線へ車線変更し、更に隣接する車線又は路側帯へ連続して車線変更しようとする場合に、2度目の車線変更を円滑に行うことができるよう改良された車線逸脱防止装置を提供する。【解決手段】車線逸脱防止装置において、車両が車線から逸脱する虞があると判定したときには(S20)、車線逸脱予防制御(転舵輪の自動転舵及び/又は警報の発出)を実行する(S50)。制御ユニットは、第一の白線を越えるドライバーの車線逸脱の意図がなしからありへ変化したと判定したときには(S30)、制御復帰条件が成立したと判定するまで車線逸脱予防制御の実行を取り止める(S40、S70)。制御ユニットは、制御復帰条件が成立したと判定しても(S70)、車両がその走行先にある第二の白線に接近する速度Vyが基準値Vyc以上であると判定したときには(S100)、車線逸脱予防制御の実行の取り止めを継続する。【選択図】図2
