Abstract

In a method and a device for controlling a driver assistance system of a vehicle, a process is carried out which includes the steps of emitting light of at least one wavelength onto a road surface under the vehicle, detecting the light reflected by the road surface, acquiring at least one piece of information on the nature of the road surface using the detected reflected light, transmitting the information on the nature of the road surface to the driver assistance system, and modifying at least one parameter of the driver assistance system such that the driver assistance system reacts depending on the nature of the road surface.
