Abstract
A device for fatigue warning in motor vehicles includes a driver sensor system for detecting driver fatigue conditions and a run-up alarm system which has an environment sensor system. The alarm system is designed to output a warning signal and/or perform a control action in the drive and/or brake system of the vehicle when the distance to a preceding vehicle drops below a warning distance. The run-up alarm system has a setting device which is configured to modify the warning distance as a function of the detected fatigue condition.
