Abstract

A system for the exact detection of the fatigue of a driver of a vehicle includes at least one camera for detecting the pupil diameter of the driver of the vehicle, at least one sensor for detecting a current luminance in the vehicle, and at least one computer module for detecting the fatigue of the driver of the vehicle by calculation. The calculation is based on the detected pupil diameter and the detected, current luminance in the vehicle.
