To provide a driver's state detection device capable of detecting an abnormality of a driver at an early stage, and capable of distinguishing a disease of the driver from a distracted state.SOLUTION: A driver's state detection device 1 includes: a driver's car behavior sensor 6; a risk prediction determination unit 10a for determining whether or not a driver is executing driving while predicting a risk on the basis of a value of the detection by the driver's car behavior sensor 6; a function decline state determination unit 10b for determining that the driver is in a function decline state when the driver is determined not to be executing driving predicting a risk by the risk prediction determination unit; and a driver's state determination unit 10c for determining that the driver has a disease when the risk prediction determination unit determines again that the driver is not executing driving predicting a risk within a predetermined time after the driver is determined to be in a function decline state by the function decline state determination unit.SELECTED DRAWING: Figure 1

    【課題】運転者の異常を早期に発見することができ、運転者の疾患を漫然状態から区別することができる運転者状態検出装置を提供する。【解決手段】本発明は、運転者状態検出装置1であって、自車挙動センサ6と、この自車挙動センサ6による検出値に基づいて、運転者がリスクを予測した運転をしているか否かを判定するリスク予測判定部10aと、このリスク予測判定部により、運転者がリスクを予測した運転をしていないと判定された場合に、運転者が機能低下状態にあると判定する機能低下判定部10bと、この機能低下判定部により、運転者が機能低下状態にあると判定された後、所定時間以内に、リスク予測判定部が、再び、運転者がリスクを予測した運転をしていないと判定した場合に、運転者に疾患があると判定する運転者状態判定部10cと、を有することを特徴とする。【選択図】図1
