METHOD AND CONTROL DEVICE FOR CONTROLLING A DRIVER ASSISTANCE SYSTEM WHEN PROVIDING ASSISTED DRIVING FUNCTIONS, DRIVER ASSISTANCE SYSTEM, VEHICLE

The invention relates to a method for controlling a driver assistance system (100) when providing assisted driving functions (AF) of a vehicle (F), comprising: - capturing traffic data (10) by means of at least one vehicle-mounted sensor (S), - obtaining swarm data (20) from at least one external device (200) for the at least one navigation section (Ai), - comparing the obtained swarm data (20) with the captured traffic data (10), - providing assisted driving functions for the at least one navigation section (Ai) depending on the comparison in two different operating modes (B1, B2): - a normal operation (B1), in which assisted driving functions of the vehicle (F) are provided by means of obtained swarm data (20) and/or the captured traffic data (10), when a comparison of the obtained swarm data (20) with the captured traffic data (10) is possible, - a special operation (B2), in which assisted driving functions of the vehicle (F), in particular only, are provided by means of the obtained swarm data (20), when a comparison of the obtained swarm data (20) with the captured traffic data (10) is not possible or is impeded.
