PROBLEM TO BE SOLVED: To prevent an own vehicle from deviating from an adjacent lane in a series of steering operation and allow the own vehicle to avoid an obstacle, appropriately responsively, even when the own vehicle avoids an obstacle existing ahead of the own vehicle by moving to the adjacent lane by steering.SOLUTION: In a case where an avoidance steering intention of a driver relative to an obstacle is detected, a vehicle travel is changed to a direction for easy to stop by means of lane-keep control. Further, in a case where a deviation to outside of a movement destination lane is predicted when completing an avoidance steering relative to the obstacle, an activation of lane deviation prevention control is advanced, and a control characteristic is changed to a direction of enhancing the control. Further, in a case where there is an operation of increasing rotation of a steering wheel after determination of the completion of the avoidance steering relative to the obstacle, dumping-torque is added. Moreover, when the control characteristic of the lane deviation prevention control is changed, an abnormality determination range of an electric power steering apparatus 1 is changed.

    【課題】たとえ自車両前方に障害物が存在し、この障害物を操舵で隣接する車線に移動して回避するような状況であっても、一連の操舵操作の中で隣接する車線からの逸脱の防止、障害物の回避を適切に応答性良く、円滑に行う。【解決手段】ドライバの障害物に対する回避操舵意思を検出した場合は、レーンキープ制御が停止し易い方向に変更させる。また、障害物に対する回避操舵が完了した際、移動先の車線から外側への逸脱が予想される場合に、車線逸脱防止制御の作動を早めると共に強める方向に制御特性を変更させる。更に、障害物に対する回避操舵が完了したと判定した後、ハンドルを切り増す操作をした場合、ダンピングトルクを付加する。また、車線逸脱防止制御の制御特性を変更した際は、電動パワーステアリング装置1の異常判定領域を変更する。【選択図】図3
