PROBLEM TO BE SOLVED: To provide a drowsiness determination device and drowsiness determination method capable of accurately determining the drowsiness state of an occupant.SOLUTION: A drowsiness determination device 100 includes: an input section 110 for receiving vehicle information indicating a movement amount of a vehicle posture with respect to a road surface and also receiving head part information indicating a movement amount of a head part of an occupant with respect to a predetermined position; and a determination section 120 for determining whether an occupant has drowsiness on the basis of the vehicle information and the head part information. When the vehicle posture is moved, the determination section 120 determines that the occupant has drowsiness on condition that the head part of the occupant is moved in a direction being the same as the movement direction of a vehicle posture and also delay time of the point of time when the head part of the occupant is moved with respect to the point of time when the vehicle posture is moved is longer than a predetermined time.SELECTED DRAWING: Figure 1

    【課題】乗員の眠気状態を精度よく判定することができる眠気判定装置および眠気判定方法を提供することである。【解決手段】眠気判定装置100は、路面に対する車両姿勢の変動量を示す車両情報を受け取り、かつ、所定の位置に対する乗員の頭部の変動量を示す頭部情報を受け取る入力部110と、車両情報および頭部情報に基づいて、乗員に眠気があるか否かを判定する判定部120と、を備え、判定部120は、車両姿勢が変動したときに、乗員の頭部が、車両姿勢の変動方向と同じ方向に変動し、かつ、車両姿勢が変動した時点に対する、乗員の頭部が変動した時点の遅延時間が所定時間より長いことを条件として、乗員に眠気があると判定する。【選択図】図1
