PROBLEM TO BE SOLVED: To provide a driver abnormality occurrence detector which can correctly detect an occurrence of abnormality when the driver's condition becomes serious after an initial postural change occurs.SOLUTION: A driver abnormality occurrence detector comprises: a postural change sensor for detecting a postural change of a driver; a confirmation unit for, when the detected postural change is a postural change that is assumed in advance to occur when there is an abnormality, and if the amount of the postural change exceeds a predetermined range, requesting the driver to confirm whether an abnormality is occurring or not, and if there is no response, outputting an abnormality occurrence detection signal; and a special monitoring mode control unit for, when there is a response to the request for confirmation indicating that no abnormality is occurring from the driver, setting a range which is narrower than a predetermined range until a predetermined time passes, and if the narrower range is exceeded, causing the confirmation unit to request the driver to confirm whether an abnormality is occurring or not. This configuration enhances the detection accuracy of occurrence of an abnormality of the driver, and can protect not only the driver's life but also surrounding pedestrians' lives.SELECTED DRAWING: Figure 1
【課題】最初の姿勢変化が生じた後に、深刻な状態に陥った時に、より正確に異常発生を検出可能な運転者異常発生検出器を提供する。【解決手段】本発明の運転者異常発生検出器は、運転者の姿勢変化を検出する姿勢変化センサと、検出した姿勢変化が予め想定される異常発生時の姿勢変化であって、その変化量が予め定めた範囲を超えた場合に、運転者に異常の発生であるのか、否かについての確認を求め、応答がない場合、異常発生検出信号を出力する確認部と、確認の求めに対し運転者から異常の発生でない旨の応答があった場合、予め定めた時間が経過するまでは、予め定めた範囲よりも狭い範囲を定め、該狭い範囲を超えた場合、確認部に、運転者に異常の発生であるのか、否かについての確認を行わせる特別監視モード制御部とを備えたことを特徴とする。当該構成により、運転者の異常発生検出精度を高め、運転者だけでなく、周りの歩行者の命を守ることができる。【選択図】図1
