In a method for detecting driver fatigue in a vehicle having a memory device in which a fatigue model is stored, a sensor which detects at least one activity of the driver, and a sensor which detects the ambient brightness, the activity information is analyzed in the fatigue model and the brightness information is used for weighting the model.

Method and device for fatigue detection

To monitor a degree of attentiveness for a driver of a vehicle, a period is determined on the basis of a speed of the vehicle. It is determined whether an eyelid closed time and/or an eyelid closing time of the driver exceeds the period.

Monitoring a degree of attention of a driver of a vehicle

In a method and a device for detecting the drowsiness of a driver in a motor vehicle, a drowsiness model is provided to determine a value characterizing the drowsiness of the driver as a function of at least one output quantity of a driver-activity sensor array. Moreover, the device for detecting drowsiness includes a brightness sensor as well as a correction model for correcting the value characterizing the drowsiness of the driver as a function of at least one output quantity of the brightness sensor.
