ARRANGEMENT AND METHOD FOR DETERMINING A GRADIENT SIGNAL IN A VEHICLE
First Claim
1. An arrangement for determining a gradient signal in a vehicle, the arrangement comprising:
- at least one position capture device which is configured to determine a position of the vehicle in an absolute system at least at a first point in time and at a second point in time and to ascertain therefrom a distance traveled of the vehicle as a motion vector, andat least one first laser distance sensor arranged on a front side of the vehicle at a predetermined angle to a vehicle longitudinal axis and configured to emit at least one first laser beam in a direction of a first measuring point in front of the vehicle at least at the first point in time and the second point in time, andat least one laser beam length sensor that is configured to ascertain the length of the at least one laser beam and at least one associated vector of the laser beam at each of the at least first point in time and second point in time, and at least one detection device that is set up to ascertain a differential vector from the motion vector and each of the ascertained vectors of the laser beam and to form a gradient signal therefrom.

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.

7. A method for determining a gradient signal in a vehicle comprising:
-
in a first step, determining a position of the vehicle in an absolute system at least at a first point in time and at a second point in time and ascertaining a traveled distance as a motion vector therefrom; and in a second step, determining a differential vector from the motion vector and vectors of the laser beam ascertained at the first point in time and the second point in time of at least one first laser distance sensor arranged on a front side of the vehicle at a predetermined angle to a vehicle longitudinal axis, the at least one first laser distance sensor emitting at least one first laser beam in the a direction of a first measuring point in front of the vehicle at least at the first point in time and the second point in time, and ascertaining a gradient signal therefrom. - View Dependent Claims (8, 9, 10)
