To provide an arousal level determination device capable of detecting an initial stage of arousal level reduction.SOLUTION: An arousal level determination device 1 for determining an arousal level of a driver driving a vehicle is comprised of a detection unit 12, and a determination unit 14. The detection unit 12 is configured to detect a body motion amount indicating a magnitude of a motion of a human body for the driver. The determination unit 14 is configured to determine an arousal level of the driver. Further, the determination unit 14 determines that the driver is in the initial stage of the arousal level reduction when the body motion amount is in a decreasing trend.SELECTED DRAWING: Figure 1
【課題】覚醒度低下の初期段階を検出することができる覚醒度判定装置を提供する。【解決手段】車両を運転する運転者の覚醒度を判定する覚醒度判定装置1であって、検出部12と、判定部14と、を備える。検出部12は、運転者について、人体の動きの大きさを示す体動量を検出するように構成される。判定部14は、運転者の覚醒度を判定するように構成される。また、判定部14は、体動量が減少傾向にある場合に運転者が覚醒度低下の初期段階にあると判定する。【選択図】図1
