Abstract

A method for classifying a roadway condition on the basis of image data from a camera system includes providing image data which is configured to image at least one portion of the surroundings of the vehicle, at least part of the portion containing the roadway on which the vehicle is driving. The method includes distinguishing diffuse reflection and specular reflection of the roadway by evaluating differences in the appearances of at least one point of the roadway in at least two images. The method also includes determining whether, in at least one image, there are disturbances that have been caused by at least one wheel of a vehicle whirling up a substance covering a roadway as said wheel travels thereover. The method further includes classifying the roadway condition into one of several roadway condition classes, taking account of the results with regard to the reflection type and the disturbance intensity.
