TRAVEL CONTROL METHOD AND TRAVEL CONTROL DEVICE

To prevent automatic travel of an own vehicle along an inappropriate target travel trajectory from giving an occupant a feeling of insecurity when generating the target travel trajectory on the basis of a travel trajectory learned or stored during manual operation.SOLUTION: In a travel control method, a first target travel trajectory is generated on the basis of a travel trajectory when an own vehicle 1 is operated through manual operation by a driver of the own vehicle 1 (S5); positions of traffic lane boundary lines of a traffic lane on which the own vehicle 1 travels are acquired (S1); a second target travel trajectory which passes a predetermined position in a traffic lane width direction in the traffic lane is generated on the basis of the acquired positions of the traffic lane boundary lines (S5); a third target travel trajectory is set at a position between the first target travel trajectory and the second target travel trajectory in the traffic lane width direction (S9); and the own vehicle 1 is controlled to travel along the third target travel trajectory (S10).SELECTED DRAWING: Figure 6 【課題】手動運転時に学習又は記憶した走行軌跡に基づいて目標走行軌道を生成する場合に、不適切な目標走行軌道に沿って自車両を自動走行させることにより乗員に与える不安感を抑制する。【解決手段】走行制御方法では、自車両１の運転者の手動運転によって自車両１を走行させたときの走行軌跡に基づいて第１目標走行軌道を生成し（Ｓ５）、自車両１が走行する車線の車線境界線の位置を取得し（Ｓ１）、取得した車線境界線の位置に基づいて車線内において車線幅方向の所定位置を通る第２目標走行軌道を生成し（Ｓ５）、車線幅方向における第１目標走行軌道と第２目標走行軌道の間の位置に第３目標走行軌道を設定し（Ｓ９）、第３目標走行軌道に沿って自車両１を走行させる（Ｓ１０）。【選択図】図６
