VEHICLE GUIDANCE SYSTEM AND METHOD FOR OPERATING A DRIVING FUNCTION IN THE PRESENCE OF A CONTRADICTION WITH MAP DATA

摘要

The invention relates to a vehicle guidance system for providing a driving function for automated longitudinal control of a vehicle. The vehicle guidance system is designed to detect, on the basis of environmental data, a first signaling unit which is located on the roadway on which the vehicle is traveling, in front of the vehicle in the direction of travel. The vehicle guidance system is furthermore designed to determine that a contradiction exists between the first signaling unit, detected on the basis of the environmental data, and map data in respect to a roadway network in which the vehicle is traveling. In addition, the vehicle guidance system is designed to effect a non-availability output in response thereto in order to inform a user of the vehicle that the first signaling unit detected on the basis of the environmental data is not taken into consideration in the driving function for automated longitudinal control of the vehicle.
