PROBLEM TO BE SOLVED: To provide a method for accurately determining the necessity for abnormality-responsive drive control to be executed when abnormality occurs in the physical condition of a driver, and to use the determination to accurately start the abnormality-responsive drive control.SOLUTION: The method determines the necessity for the abnormality-responsive drive control, which is executed when abnormality occurs in the physical condition of the driver, based on a pressing force applied by the drivers body, wherein the determination for necessity is varied in accordance with characteristics of the attitude of the driver. The pressing force selected from three pressing forces, which are a pressing force applied by the back of the driver, a pressing force applied by the hip, and a pressing force applied by the left foot, is used. The driver is permitted to start the abnormality-responsive drive control when it is determined that the control is necessary.COPYRIGHT: (C)2013,JPO&INPIT【課題】運転者の体調に異常があるときに実行する異常時対応運転制御の要否を的確に判定する方法を提供し、また該判定を異常時対応運転制御の的確な始動+に生かす。。【解決手段】運転者の体調に異常があるときに実行する異常時対応運転制御の要否を運転者の体より及ぼされる押圧力に基づいて判定し、その際、運転者の姿勢の特徴に応じて要否判定を異ならせる。押圧力としては、運転者の脊部より及ぼされる押圧力、臀部より及ぼされる押圧力、左足より及ぼされる押圧力の3者から選択された押圧力を使用する。運転者による異常時対応運転制御の始動は、上記の要否判定が要と判定されたとき許可する。【選択図】図1
