Driver assistance system for assisting a driver in operating a vehicle

The invention relates to a driver assistance system for assisting a driver when driving a vehicle, wherein the driver assistance system comprises preferably at least one sensor, which is configured to detect a driving situation of a vehicle at least partially and at least a first data interface for reading in traffic data of a road ahead. Furthermore, the driver assistance system preferably comprises at least a second data interface for reading road data, in particular topography and / or carriageway profile of a forward roadway portion and / or back of a roadway portion. A prediction module of the driver assistance system is preferably adapted to simulate based on the current driving situation, the traffic data and the road data of at least a future driving scenario, dynamic and in turn to simulate dynamically on the basis of at least one future driving scenarios possible trajectories of the vehicle and outputting. An optimization module of the driver assistance system is preferably configured to based on at least one predetermined constraint, which characterizes a driving style attribute of the driver assistance system to select one of the possible trajectories, and output and a control module is preferably connected to the longitudinal system, the brake system and / or the drive system of the vehicle in the are connected, in order to guide the vehicle based on the selected trajectory.
