To provide a driver condition determining device that can sense deterioration of a physical function of a driver to promptly confirm a determination of an abnormal condition, early enough before the driver cannot drive a vehicle any more.SOLUTION: A driver condition determining device 10 comprises a vibrating device 14 that applies vibrations to a steering wheel 2, a vibration detector 16 that detects vibrations of the steering wheel, and a controller 18 that controls the vibrating device. The controller makes the vibrating device apply vibrations of predetermined vibration frequencies f0 to the steering wheel, calculates steering torque levels in the vibration frequencies, on the basis of vibrations detected by the vibration detector, and determines that a driver is in an abnormal condition, when an average value A of the steering torque levels during application of vibrations is equal to a first threshold Th1 or more and/or when a standard deviation SD of the steering torque levels during the application of vibrations is equal to a second threshold Th2 or more.SELECTED DRAWING: Figure 4

    【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、運転者状態判定装置を提供する。【解決手段】運転者状態判定装置10は、ステアリングホイール2に振動を付与する振動装置14と、ステアリングホイールの振動を検出する振動検出器16と、振動装置を制御するコントローラ18とを備え、コントローラは、振動装置によりステアリングホイールに所定の加振周波数f0の振動を付与し、振動検出器により検出された振動に基づき、加振周波数における操舵トルクレベルを算出し、振動の付与中における操舵トルクレベルの平均値Aが第1閾値Th1以上、及び/又は、振動の付与中における操舵トルクレベルの標準偏差SDが第2閾値Th2以上である場合に、運転者が異常状態であると判定する。【選択図】図4
