To provide a motion sickness estimation device capable of improving estimation accuracy of motion sickness.SOLUTION: This motion sickness estimation device comprises: an opening/closing detection unit 31 that detects the opened/closed state of occupant's eyes of a vehicle; a face direction estimation unit 32 that estimates the face direction of the occupant; and an occupant state estimation unit 33 that calculates the progress speed of motion sickness of the occupant on the basis of the opened/closed state of the eyes and the face direction. The occupant state estimation unit calculates a reference value of the progress speed on the basis of a first value indicating a vehicle behavior and a second value indicating the state of an internal environment of the vehicle, and calculates the progress speed by correcting the reference value on the basis of the opened/closed state of the eyes and the face direction.SELECTED DRAWING: Figure 3

    【課題】乗り物酔いの推定精度を向上させる乗り物酔い推定装置を提供する。【解決手段】乗り物酔い推定装置は、乗り物の乗員の眼の開閉状態を検知する開閉検知部31と、乗員の顔向きを推定する顔向き推定部32と、眼の開閉状態及び顔向きに基づいて、乗員に対する乗り物酔いの進行速度を算出する乗員状態推定部33とを備える。乗員状態推定部は、乗り物の挙動を示す第1の値と、乗り物の内部環境の状態を示す第2の値とに基づいて進行速度の基準値を算出し、眼の開閉状態及び顔向きに基づいて基準値を補正することによって進行速度を算出する。【選択図】図3
