Abstract
A drowsiness determination system includes a first acquirer, a second acquirer, a third acquirer, and a determiner. The first acquirer acquires vibration information indicating the vibration of a vehicle. The second acquirer acquires head information indicating a variation in the movement of the head of an occupant. The third acquirer acquires sitting height information indicating the sitting height of the occupant. The determiner determines whether the occupant is drowsy based on the head information and the sitting height information, when the vibration information indicates the occurrence of the vibration of the vehicle.
