Bevorzugte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.The Solution to this problem is done with a method with the Features of claim 1. Preferred embodiments of Invention are specified in the subclaims.
Bei einem Verfahren zur Bestimmung von Anhängerdaten werden erfindungsgemäß im hinteren Bereich des Zugfahrzeugs vorhandene Abstandssensoren zur Ermittlung der Anhängerdaten genutzt, indem während der Fahrt die unterschiedlichen Abstände zwischen Zugfahrzeug und Anhänger außerhalb der Fahrzeugmitte bestimmt und weiterverarbeitet werden. Dadurch ist es möglich, die im Zugfahrzeug vorhandenen Abstandssensoren auch bei einer Anhängerfahrt zu nutzen, wobei zunächst aus den Fahrdaten Anhängerdaten bestimmt werden, die dann im weiteren Betrieb verwendet werden können.at a method of determining trailer data According to the invention in the rear of the towing vehicle existing distance sensors used to determine the trailer data, while driving the different distances between towing vehicle and trailer outside the Vehicle center determined and processed. This is it is possible, the existing in the towing vehicle distance sensors also to use in a trailer trip, where initially off the driving data trailer data are determined, which then in further operation can be used.
Bevorzugt werden die Abstandsdaten von zwei in den Außenbereichen des rückseitigen Stoßfängers angeordneten Sensoren bestimmt. Bevorzugt sind die Abstandssensoren als Parkabstandssensoren ausgelegt. Die im hinteren Bereich eines Kraftfahrzeugs, insbesondere in den Stoßfängern, vorhandenen Parkabstandssensoren oder Park Distance Control Sensoren können auf diese Weise auch im Anhängerbetrieb verwendet werden. Insbesondere mit den äußeren Sensoren kann dann eine Abstandsmessung zwischen dem Zugfahrzeug und dem Anhänger durchgeführt werden.Prefers are the distance data of two in the outdoor areas Rear bumper arranged Sensors determined. Preferably, the distance sensors are used as parking space sensors designed. The at the rear of a motor vehicle, in particular in bumpers, available parking distance sensors or Park Distance Control sensors can work this way too be used in trailer operation. Especially with the outside Sensors can then take a distance measurement between the towing vehicle and the trailer.
Bevorzugt wird aus den Abstandsmessungen der Abstand der Achse des Anhängers zur Kupplung des Zugfahrzeugs bestimmt. In einer anderen bevorzugten Ausgestaltung wird aus den Abstandsmessungen die Länge des Anhängers bestimmt. Durch die Ermittlung dieser Daten wird bestimmt, welche Abmessungen der Anhänger hat und wo die Achse liegt. Bevorzugt wird auf der Basis dieser Daten bzw. mit den so erhaltenen Anhängerdaten eine Trajektorie für das Zugfahrzeug mit dem Anhänger berechnet. Mit den so erhaltenen Anhängerdaten kann während des normalen Fahrbetriebs eine Trajektorie ermittelt bzw. vorausberechnet werden, die insbesondere beim langsamen Fahren durch schmale Einfahrten oder im Rückwärtsfahrbetrieb als zusätzliche Überprüfungs- oder Warndaten für den Fahrer verwendet werden können.Prefers becomes the distance measurements from the distance of the axle of the trailer intended for coupling the towing vehicle. In another preferred Embodiment becomes the distance measurements from the length of the trailer. By identifying this data determines what dimensions the trailer has and where the axis lies. It is preferred on the basis of this data or with the trailer data thus obtained a trajectory for the towing vehicle is charged with the trailer. With the so obtained trailer data can during the normal Driving operation, a trajectory is calculated or predicted, especially when driving slowly through narrow driveways or in reverse drive mode as an additional verification or warning data can be used for the driver.
Bei der Berechnung der Anhängerdaten wird bevorzugt ein mittiger Aufbau des Anhängers über der Achse des Anhängers angenommen. Dadurch ist die Berechnung wesentlich vereinfacht bzw. ohne weitere Angaben mit Hilfe der aus den Abstandssensoren gewonnenen Daten möglich. In einer bevorzugten Ausgestaltung der Erfindung wird eine Vielzahl von Einzelmessungen durchgeführt und aus diesen Einzelmessungen wird ein Mittelwert gebildet. Dadurch wird eine hohe Genauigkeit bei der Berechnung erreicht. In einer anderen bevorzugten Weiterentwicklung der Erfindung wird das Verfahren durch die elektrische Kontaktierung des Zugfahrzeugs mit dem Anhänger eingeleitet. Dadurch wird eine automatische Ermittlung der Anhängerdaten eingeleitet. Bevorzugt wird diese Einleitung noch überprüft, nämlich dadurch, dass die Kontaktierung durch Messungen der Abstandssensoren bestätigt werden. Nach Kontaktierung werden von beiden Abstandssensoren Messungen in einem bestimmten Nahbereich erwartet.at the calculation of the trailer data is preferably a center Structure of the trailer above the axle of the trailer accepted. As a result, the calculation is significantly simplified or without further information with the help of the distance sensors Data possible. In a preferred embodiment of the invention a variety of individual measurements is carried out and From these individual measurements an average value is formed. Thereby a high accuracy in the calculation is achieved. In a Another preferred development of the invention is the method by the electrical contacting of the towing vehicle with the trailer initiated. This will automatically detect trailer data initiated. Preferably, this introduction is still checked namely the fact that the contacting by measurements the distance sensors are confirmed. After contacting Both measurements are taken in a given distance Close range expected.
In
einer bevorzugten Ausgestaltung der Erfindung wird der Winkel, mit
dem der Anhänger dem Zugfahrzeug nachläuft, mit
folgender Gleichung ermittelt, nämlich:
Dabei sind m1 und m2 die Abstandsmesswerte der Abstandssensoren und c der seitliche Abstand der Abstandssensoren von der Fahrzeugmitte.there m1 and m2 are the distance measurements of the distance sensors and c the lateral distance of the distance sensors from the vehicle center.
Nachfolgend wird die Erfindung anhand eines in der Zeichnung dargestellten bevorzugten Ausführungsbeispiels weiter erläutert. Im Einzelnen zeigen die schematischen Darstellungen in:following the invention is based on a preferred illustrated in the drawing Embodiment further explained. In detail show the schematic representations in:

Dabei ist a der Abstand des Kugelkopfs der Anhängerkupplung zur Mitte der Hinterachse und b der Abstand der Abstandssensoren S1 und S2 zur Hinterachsmitte.there a is the distance of the ball head of the trailer hitch to Center of the rear axle and b the distance of the distance sensors S1 and S2 to the rear axle center.
Die
Länge e, die den Abstand der Kupplung des Anhängers
zur Achsmitte des Anhängers beschreibt ergibt sich zu
Dabei ist R der Rollradius des Zugfahrzeugs, der sich z. B. mit dem Lenkwinkel und den Daten für die Fahrzeuggeometrie aus einem Einspurmodell oder einer Look-Up-Table für das Fahrzeug ergibt.there R is the rolling radius of the towing vehicle, the z. B. with the steering angle and the data for the vehicle geometry from a single track model or gives a look-up table for the vehicle.

Die Güte der Einzelwerte kann durch vielfache Messung und Mitteilung verbessert werden.The Goodness of the individual values can be achieved by multiple measurement and notification be improved.
Mit dem erfindungsgemäßen Verfahren können Anhänger im laufenden Betrieb vermessen werden. Die Abstandsmesssysteme können daher so erweitert werden, dass auch Fahrzeuge mit Anhänger rückwärts geparkt werden können. Außerdem kann der Fahrer auf Gefahrensituationen, die in der Vorwärtsfahrt durch zu große Lenkwinkel entstehen, hingewiesen werden.With the method of the invention can Trailer can be measured during operation. The distance measuring systems can therefore be extended so that even vehicles with Trailers can be parked backwards. In addition, the driver can be on dangerous situations in the driving forward due to excessive steering angles, be pointed out.
