To provide a driver abnormality sign detector capable of detecting a decline in the physical functions of a driver at a sufficiently early stage before the driver becomes incapable of driving, and of determining the abnormality status at an early stage.SOLUTION: A driver abnormality sign detector 100 includes: an external camera 21 that acquires driving environment information of a vehicle; a radar 22; a navigation system 23; a positioning system 24; an in-vehicle camera 32 that detects the driver's line of sight; and a controller 10 configured to detect an abnormality sign of the driver based on the driving environment information and the driver's line of sight. The controller identifies points needed to be viewed that the driver should view based on the driving environment information, determines whether or not the driver has viewed the visible points based on the driver's line of sight, and detects the abnormality sign of the driver based on the fact that the driver has not viewed the points needed to be viewed.SELECTED DRAWING: Figure 5
【課題】運転者が運転不能となるより十分に早い段階で、運転者の身体機能の低下を検知し異常状態の判定を早期に確定することが可能な、運転者異常予兆検出装置を提供する。【解決手段】運転者異常予兆検出装置100は、車両の走行環境情報を取得する車外カメラ21、レーダ22、ナビシステム23、測位システム24と、運転者の視線を検出する車内カメラ32と、走行環境情報と運転者の視線とに基づき、運転者の異常予兆状態を検出するように構成されたコントローラ10とを備え、コントローラは、走行環境情報に基づき、運転者が視認すべき要視認箇所を特定し、運転者の視線に基づき、運転者が要視認箇所を視認したか否かを判定し、運転者が要視認箇所を視認しなかったことに基づき、運転者の異常予兆状態を検出する。【選択図】図5
