Abstract
A method and a device are for determining the presence and type of a roadway coating by a vehicle camera system. The vehicle camera system records at least one image of the surroundings of the subject vehicle. The at least one image is evaluated to detect indications of the presence of a roadway coating including a characteristic feature of the roadway coating that results as the roadway is traveled over by the subject vehicle or by another vehicle. The detected indications and characteristic feature are taken into consideration in the determination of the presence and type of a roadway coating. The result of the determination of the roadway coating, or a friction coefficient estimation derived therefrom, is output to a driver assistance function, a vehicle control function or as information to the driver.
