Method for sensing and processing the carriageway condition of a carriageway on which a vehicle is driven

A method for detecting and processing a carriageway surface condition of a carriageway on which a vehicle is driven, by means of at least one structure-borne sound sensor, the method comprising:

• detecting sound signals spreading through the vehicle by means of the at least one structure-borne sound sensor;
• drawing conclusions about the carriageway surface condition on a basis of the detected sound signals;
• determining a section of a route on which the vehicle is currently travelling;
• assigning the detected carriageway condition to the section of the route;
• transmitting the section of the route and the detected carriageway surface condition assigned to the section of the route are transmitted to a computer network;
• making the information about the detected carriageway surface condition assigned to the section of the route available via the computer network;
• comparing the detected carriageway surface condition based on the detected sound signals with a carriageway surface condition based of the stored sound signals stored in the computer network for the section of the route on which the vehicle is currently travelling;
• and
• in the event of a difference between the detected sound signal for the carriageway and the stored sound signal for the carriageway, concluding that the vehicle is at least partially departing from the carriageway, if concluding that the vehicle is at least partially departing from the carriageway a warning signal is emitted to the driver.
