Abstract

A driver assistance device for warning a driver of a motor vehicle of a risk of departure from the lane or from the lane is described, having at least one image-transmitting sensor, an evaluation device, connected to the image-transmitting sensor, for detecting edge-of-lane and/or lane markings and/or edges of lanes in the area sensed by the image-transmitting sensor, and a warning device which is connected to the evaluation device, in which driver assistance device in addition at least one distance-transmitting sensor is connected to the evaluation device, with which sensor the distance from objects which are elevated with respect to the surface of the lane can be determined in the region of the edge of the lane, in particular of a structural boundary of the edge of the lane.
