PROBLEM TO BE SOLVED: To provide an arousal level estimation device capable of estimating an arousal level of a driver of a vehicle, which has an automatic drive mode and a manual drive mode, with high precision.SOLUTION: A vehicle can be switched between an automatic drive mode and a manual drive mode, and comprises: a vehicle behavior detection part 11 which detects drive information on the vehicle; a first arousal level recognition part 12 which recognizes a first arousal level of a driver from the detected drive information; a biological information detection part 16 which detects one or more pieces of biological information on the driver; a second arousal level recognition part 17 which recognizes a second arousal level of the driver from the one or more pieces of detected biological information on the driver; and an arousal level estimation part 15 which estimates a third arousal level of the driver from at least one of the recognized first arousal level and second arousal level. The arousal level estimation part 15 estimates the third arousal level from the first arousal level and the second arousal level in the manual drive mode and estimates the third arousal level from the second arousal level in the automatic drive mode.SELECTED DRAWING: Figure 1

    【課題】自動運転モードと手動運転モードとがある車両のドライバの覚醒度を高精度に推定することができる覚醒度推定装置を提供する。【解決手段】車両では、自動運転モードと手動運転モードとが切替え可能であり、車両の運転情報を検出する車両挙動検出部11と、検出された運転情報からドライバの第1の覚醒度を認識する第1の覚醒度認識部12と、ドライバの1以上の生体情報を検出する生体情報検出部16と、検出された1以上の生体情報からドライバの第2の覚醒度を認識する第2の覚醒度認識部17と、認識された第1の覚醒度及び第2の覚醒度の少なくとも一方から、ドライバの第3の覚醒度を推定する覚醒度推定部15とを備える。覚醒度推定部15は、手動運転モードでは、第1の覚醒度と第2の覚醒度とから、第3の覚醒度を推定し、自動運転モードでは、第2の覚醒度から第3の覚醒度を推定する。【選択図】図1
