Abstract
Niveaueinstellung für Abstandsmessgeräte in Fahrzeugen mit einem oder mehreren elektromagnetischen Pulslaufzeitsensorkanälen, wobei mindestens einer der Pulslaufzeitsensorkanäle auf die Fahrbahn vor dem Fahrzeug gerichtet ist und wobei die Pulsform und der Abstand des Echos vor dem Fahrzeug zur Nickwinkeleinstellung des Sensorsystems ausgewertet werden.level adjustment for distance measuring devices in vehicles with one or more electromagnetic pulse transit time sensor channels, wherein at least one of the pulse transit time sensor channels on the road ahead of Vehicle is directed and where the pulse shape and the distance of Echoes in front of the vehicle for pitch angle adjustment of the sensor system be evaluated.
Description
Die
Erfindung betrifft eine Niveaueinstellung für Abstandsmessgeräte für Fahrzeuge.
(Nächstliegender
Stand der Technik ist die
Abstandsmessgeräte für Warn- und Abstandshaltefunktion in Kraftfahrzeugen müssen so ausgerichtet sein, dass sie die Verkehrssituation und die Fahrzeuge vor dem eigenen Fahrzeug erfassen.Distance measuring devices for warning and spacing function in motor vehicles must be so aligned that they have the traffic situation and the vehicles in front of their own Capture vehicle.
Dazu sind bisher zwei Methoden bekannt.
- – Das System wird so ausgelegt, dass vor dem Sensor eine so große Fläche erfasst wird, dass alle Nickwinkel und Fahrbahnkrümmungen abgedeckt werden.
- – Das System wird abgeleitet von der Einfederung des Fahrzeugs nachgeregelt.
- - The system is designed to detect such a large area in front of the sensor that it covers all pitch angles and lane curvatures.
- - The system is readjusted derived from the deflection of the vehicle.
Beide
Systemansätze
haben erhebliche Nachteile;
Zum Einen wird mit der ersten Lösung eine
viel zu große
Fläche
betrachtet, zum Anderen spiegelt die Einfederung des Fahrzeugs nur
die Fahrbahnbeschaffenheit und nicht den Winkel Fahrzeug/Fahrbahn
wider.Both system approaches have considerable disadvantages;
On the one hand, with the first solution a much too large area is considered, on the other hand, the deflection of the vehicle reflects only the road surface and not the angle vehicle / road.

Dabei werden Laserstrahlen auf die Fahrbahnfläche gerichtet und die Entfernungen ausgewertet. Eine Unterscheidung von Zielen (anderen Fahrzeugen) und der Straßenoberfläche durch unterschiedliche Impulsformen des Echos ist dort allerdings nicht beschrieben.there Laser beams are directed at the road surface and the distances evaluated. A distinction of goals (other vehicles) and the road surface through different pulse forms of the echo is not there described.

Diese Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst.Of the Invention is based on the object, an optimized level adjustment for distance measuring devices for vehicles to accomplish. This object is achieved with the features of the claim 1 solved.
