PROBLEM TO BE SOLVED: To start lane change assistance by the operation of a driver without waiting for an allowance time.SOLUTION: Provided is a lane change assist device for providing lane change assistance for making a vehicle change lanes from a driving lane to an adjacent lane, the lane change assist device comprising: a lane change assist unit for providing lane change assistance a preset allowance time after a direction indicator lamp on an adjacent lane side is switched to an on state by the operation of a vehicle driver; and a determination unit for determining whether or not the amount of steering on the adjacent lane side by the driver has become greater than or equal to a steering amount threshold during the allowance time, or determining whether or not the vehicle has moved a preset lateral distance to the adjacent lane side by steering by the driver during the allowance time. When it is determined by the determination unit that the amount of steering has become greater than or equal to the steering amount threshold during the allowance time, or that the vehicle has moved a preset lateral distance to the adjacent lane side during the allowance time, the lane change assist unit starts lane change assistance before the allowance time elapses.SELECTED DRAWING: Figure 4
【課題】運転者の操作により余裕時間を待つことなく車線変更支援を開始することができる。【解決手段】走行車線から隣接車線へ向かって車両を車線変更させる車線変更支援を行う車線変更支援装置であって、車両の運転者の操作により隣接車線側の方向指示器が点灯状態に切り替えられてから予め設定された余裕時間の経過後に、車線変更支援を行う車線変更支援部と、余裕時間中に運転者による隣接車線側の操舵量が操舵量閾値以上になったか否かの判定、又は、余裕時間中に運転者の操舵により車両が予め設定された横方向距離を隣接車線側に移動したか否かの判定を行う判定部と、を備え、車線変更支援部は、判定部により余裕時間中に操舵量が操舵量閾値以上になったと判定された場合、又は、判定部により余裕時間中に車両が横方向距離を隣接車線側に移動したと判定された場合、余裕時間の経過前に車線変更支援を開始する。【選択図】図4
