Abstract

In a method for providing road users with information about a route section which is traveled along by a motor vehicle before a dangerous situation, the position and the duration of travel of the motor vehicle are repeatedly sensed along the route section using a sensor system in the motor vehicle. The measured values of the sensor system are stored as route points if the angular difference, weighted with the distance traveled along since the route point last stored, between the current direction of travel and the direction of travel at the route point last stored exceeds a predefined threshold value. A route point is stored when a warning function in the motor vehicle is activated in the dangerous situation, and the position of at least one route point and the current position of the motor vehicle are passed on in a warning message to the road users in a limited surrounding area. These measures inform the road users quickly and comprehensively about dangerous situations in the road traffic.
