Abstract

An arrangement determines a gradient signal in a vehicle. The arrangement has: a position capture device that determines a vehicle position at a first and second time and ascertains therefrom a distance traveled as a motion vector, and a laser distance sensor on the vehicle front at an angle to a vehicle longitudinal axis and configured to emit a laser beam in a direction of a first measuring point in front of the vehicle at the first and second time, and a length sensor to ascertain the length of the laser beam and its associated vector at the first and second time, and at least one detection device to ascertain a differential vector from the motion vector and the ascertained vectors and to form a gradient signal therefrom.
