Abstract
For determining a state of a pavement from surroundings sensor data, local data received from at least one device that measures a local pavement state or coefficient of friction is merged with camera image data received from a camera for imaging a pavement extending in front of the vehicle. When analyzing the camera image data, the local data representing the measured pavement state or coefficient of friction is assigned to individual image sectors of a camera image while taking odometric and time information into account to achieve proper correspondence, and the local data is taken into account for supporting and/or plausibility-checking of an anticipatory estimation of the local coefficient of friction or pavement state based on the camera image data.
