Claim 4:
5. A driver assistance system for controlling a vehicle, the driver assistance system comprising:
at least one sensor to detect further vehicles in the surroundings of the vehicle;
a memory module storing a digital map;
a GPS module; and
a processor, wherein the processor is configured to:
obtain a sensor-based position of the vehicle from the GPS module;
determine an instantaneous vehicle position in the digital map based on the obtained sensor-based position;
obtain an expected setpoint traffic density that is assigned to the instantaneous vehicle position in the digital map;
use the at least one sensor to obtain an instantaneous actual traffic density in the surroundings of the vehicle;
compare the obtained instantaneous actual traffic density to the obtained expected setpoint traffic density, thereby obtaining a difference value; and
in response to the difference value being greater than a predefined threshold, the processor, re-determining the instantaneous vehicle position in the digital map to control an automated drive of the vehicle based on the re-determined instantaneous vehicle position.
