Abstract: A sensor arrangement which contains for a vehicle control system, comprises a buffer for geographic information, whereby the geographic information is suitable to describe at least one possible route of the vehicle. An input interface selects subsets of the geographic information stored in the buffer in response to at least one position-related parameter which is entered at the input interface. An output interface selects subsets of the geographic information corresponding to the parameter values provided, which subsets are transmitted for further processing in the vehicle control system.

Abstract: The invention concerns a process for updating map data of a navigation system in a vehicle, wherein the navigation system includes a digital map of a road and path network as well as a digital supplemental map, wherein in the digital supplemental map data supplemental to the road and path network are stored. The process includes the steps: a) producing differential data for an updated digital map, using the digital map, b) replacing the digital map in the vehicle with the updated digital map, c) updating the digital supplemental map in the vehicle using the differential data.

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.
