Abstract

A vehicle lighting-based roadway obstacle notification for a motor vehicle has a vehicle headlamp system with a controllable light distribution. A camera is aligned parallel to a forward driving direction records a part of the roadway surface lying in front of the motor vehicle which includes a multiplicity of roadway detection paths. Camera data are individually evaluated in relation to ranges and at least one quantity from among a magnitude of a vertical dimension hi of the roadway, a magnitude of a gradient gradx;i of the roadway, and an instantaneous speed vmom of the motor vehicle, with respect to the roadway detection paths. When at least one predetermined condition in respect of at least one of these quantities is complied with, the vehicle headlamp system is controlled in order to illuminate a part of the width of the roadway in which a roadway anomaly has been detected.
