The Driver Alert System identifies failing concentration on the part of the driver and provides the driver with a five-second acoustic warning as well as an optical indication, recommending the driver to take a break, on the instrument cluster. If the driver does not take a break within 15 minutes, the warning is repeated once. At the beginning of each trip, the system analyses factors such as the driver’s characteristic steering behavior. On the road, the Driver Alert System continuously evaluates signals such as the steering angle. In the case of deviations from the steering behavior registered at the beginning of the trip, optical and acoustic alarms are initiated.
