PROBLEM TO BE SOLVED: To provide a technique capable of suppressing such a situation in which execution of a proper retreat travel support is inhibited due to an operation not intended by a driver.SOLUTION: In retreat travel support processing, in S110, a state in which, a driver of a vehicle cannot perform a normal drive operation, (hereafter, called a drive impossible state) is detected. When the drive impossible state is detected, in S140, execution of retreat deceleration control for stopping a vehicle on a retreat place according to a peripheral state of the vehicle, is started. According to execution start of the retreat deceleration control, in S130, execution of pretensioner control for winding up a seat belt on a driver seat of the vehicle is started. Since the driver who becomes in the drive impossible state is firmly fixed to a backrest of the seat by the seat belt, so that, an unnecessary steering operation, accelerator operation, and brake operation due to falling to a front side of the driver, can be suppressed.SELECTED DRAWING: Figure 3

    【課題】運転者の意図しない動作により、適切な退避走行支援の実行が妨げられることを抑制可能な技術を提供する。【解決手段】退避走行支援処理では、S110において、車両の運転者が正常に運転操作を行うことができない状態(以下、運転不能状態)を検出する。運転不能状態を検出した場合には、S140において、車両の周辺状況に応じた退避場所に車両を停止させるための退避減速制御の実行を開始する。また、この退避減速制御の実行開始に伴い、S130において、車両の運転席におけるシートベルトを巻き上げるプリテンショナー制御の実行を開始する。運転不能状態に陥った運転者がシートベルトによって座席の背もたれに強く固定されるため、例えば運転者の前方への倒れ込み等による不要なステアリング操作やアクセル操作やブレーキ操作等を抑制できる。【選択図】図3
