Abstract
A method and a device for estimating the coefficient of friction by a 3D camera. The 3D camera records at least one image of the vehicle's surroundings. The image data of the 3D camera is used to produce a height profile of the road surface in the entire space ahead of the vehicle. Based on the height profile, the local coefficient of friction of the road surface that is to be expected in the space ahead of the vehicle is estimated.
