1. A driving assistance system for a vehicle, comprising:
an environment sensor system configured to receive surroundings data of the vehicle;
a processor;
a memory in communication with the processor and storing instructions executable by the processor to configure the driving assistance system to implement:
an evaluation unit configured to determine a traffic density in a surrounding area of the vehicle based on the surroundings data; and
a determination unit configured to determine a confidence value for the traffic density determined by the evaluation unit wherein
the confidence value comprises a weighted sum of:
a confidence value of objects detected on a lane,
a confidence value of a detected lane, and
a confidence value of a detection range of the environment sensor system of the vehicle; and
a device for an automated driving function, wherein the device is configured to carry out the automated driving function when the determined confidence value is greater than or equal to a threshold value.
