To provide a traffic lane deviation prevention device that is improved so as to limit a traffic lane deviation prevention control even when a vehicle travels in a junction area or a branch area of a road and avoid a driver's feeling of annoyance caused by automatic steering of a steered wheel and an issuance of a warning.SOLUTION: Although a control unit of a traffic lane deviation prevention device executes a traffic lane deviation prevention control (automatic steering of steered wheels and/or issuing of warning) (S60) when the control unit determines that there is a risk of a vehicle deviating from a traffic lane (S40), the control unit does not execute the traffic lane deviation prevention control when the control unit determines that a lateral speed and lateral acceleration of the vehicle increase within a predetermined time from a point in time the vehicle starts accelerating and decelerating, and that there is an adjacent traffic lane on the side of the traffic lane on which the lateral speed and lateral acceleration increase (S20, S30).SELECTED DRAWING: Figure 2

    【課題】車両が道路の合流領域や分岐領域を走行する場合にも、車線逸脱予防制御が制限され、ドライバーが転舵輪の自動転舵や警報の発出に起因する煩わしさを感じることが回避され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】車線逸脱防止装置の制御ユニットは、車両が車線から逸脱する虞があると判定したときには(S40)、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(S60)が、車両の加減速が開始された時点から所定の時間以内に車両の横速度及び横加速度が増大し、且つ車線に対し横速度及び横加速度が増大する側に隣接車線が存在すると判定したときには、車線逸脱予防制御を実行しない(S20、S30)。【選択図】図2
