Abstract
A method for classifying eye opening data of an occupant's eye in a vehicle, to detect drowsiness/microsleep, including generating a first eye opening data record at a first measuring time in a sliding time window, the first record including a measuring point, representing a first eye opening degree, a first eyelid speed and/or acceleration of motion of the occupant's eye at the first measuring time; acquiring a second eye opening data record at a second measuring time, the second record including at least one acquisition point, representing a second eye opening degree, a second eyelid speed of motion and/or acceleration of motion of the occupant's eye; and executing a cluster analysis, using the measuring point and the acquisition point to assign at least the first and/or second record to a first data cluster, to classify the eye opening data; the first cluster representing an opening state of the occupant's eye.
