Aus dem Stand der Technik sind Fahrerassistenzsysteme, wie z. B. eine Abstandsregelung, bekannt. Hierzu ist an einem Fahrzeug, insbesondere in einem Frontbereich, eine Erfassungseinheit angeordnet. Mittels der Erfassungseinheit werden vorausfahrende Fahrzeuge und ein Abstand zu einem vorausfahrenden Fahrzeug ermittelt. Zur Sicherstellung einer derartigen Funktion ist Vorraussetzung, dass die Erfassungseinheit mit deren Erfassungsbereich exakt ausgerichtet ist. Ist die Erfassungseinheit nicht exakt ausgerichtet, kann dies zu Fehlfunktionen des entsprechenden Fahrerassistenzsystems führen.Out the prior art are driver assistance systems, such. Legs Distance control, known. This is on a vehicle, in particular arranged in a front area, a detection unit. through the registration unit will be preceding vehicles and a distance determined to a preceding vehicle. To make sure Such a function is a prerequisite that the detection unit is aligned exactly with the detection area. Is the registration unit not Precisely aligned, this can lead to malfunction of the corresponding Driver assistance system lead.

Der Erfindung liegt die Aufgabe zugrunde, ein verbessertes Verfahren und eine Vorrichtung zur Ausrichtung einer an einem Fahrzeug angeordneten Erfassungseinheit, insbesondere eines Radarsensors, in Bezug auf eine geometrische Fahrachse des Fahrzeuges anzugeben.Of the Invention is based on the object, an improved method and a device for aligning a detection unit arranged on a vehicle, in particular a radar sensor, with respect to a geometric Indicate the driving axle of the vehicle.
Die Aufgabe wird erfindungsgemäß hinsichtlich des Verfahrens durch die im Anspruch 1 und hinsichtlich der Vorrichtung durch die im Anspruch 4 angegebenen Merkmale gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.The Task is according to the invention in terms of Method by the in claim 1 and in terms of the device solved by the features specified in claim 4. advantageous Further developments of the invention are the subject of the dependent claims.
Das erfindungsgemäße Verfahren zum Ausrichten zumindest einer Erfassungseinheit eines Fahrerassistenzsystems eines Fahrzeuges in Bezug auf eine geometrische Fahrachse des Fahrzeuges sieht vor, dass mittels Detektionseinheiten eine Isttrajektorie einer Abtastbewegung der Erfassungseinheit anhand von der Erfassungseinheit ausgesendeten Signalen ermittelt wird. Erfindungsgemäß wird eine Solltrajektorie der Abtastbewegung der Erfassungseinheit vorgegeben, die mit der Isttrajektorie der Abtastbewegung verglichen wird und anhand einer aus dem Vergleich ermittelten Differenz eine Fehleinstellung der Erfassungseinheit ermittelt wird.The inventive method for aligning at least a detection unit of a driver assistance system of a vehicle in terms of a geometric driving axis of the vehicle provides in that by means of detection units an actual trajectory of a scanning movement the detection unit emitted by the detection unit Signals is determined. According to the invention a desired trajectory of the scanning movement of the detection unit predetermined which is compared with the actual trajectory of the scanning movement and Based on a difference determined from the comparison, an incorrect setting of the Detection unit is determined.
Beispielsweise handelt es sich bei der Erfassungseinheit um einen Radarsensor, der z. B. zur Erfassung eines vorausfahrenden Fahrzeuges an dem Fahrzeug angeordnet ist, wobei die Erfassungseinheit Bestandteil eines Fahrerassistenzsystems in Form einer Abstandsregelung sein kann.For example if the detection unit is a radar sensor, the z. B. for detecting a preceding vehicle on the vehicle is arranged, wherein the detection unit part of a driver assistance system may be in the form of a distance control.
Anhand des erfindungsgemäßen Verfahrens kann in Gewinn bringender Weise ein Abtastbereich, insbesondere ein Erfassungsbereich, von beispielsweise als Radarkeulen ausgesandten Signalen einer als Radarsensor ausgeführten Erfassungseinheit auf einfache Art und Weise ermittelt und anschließend ausgerichtet werden. Dabei kann die Ausrichtung des Erfassungsbereiches besonders vorteilhaft sowohl horizontal als vertikal ausgerichtet werden, da die Solltrajektorie der Abtastbewegung der Erfassungseinheit vorgegeben wird.Based The process of the invention can be used in profit a scanning area, in particular a detection area, for example, emitted as radar signals of a Radar sensor executed detection unit to simple Way and then be aligned. The orientation of the detection range can be particularly advantageous be aligned both horizontally and vertically, since the target trajectory the scanning movement of the detection unit is specified.
Insbesondere werden zur Ermittlung der Isttrajektorie der Abtastbewegung der Erfassungseinheit bevorzugt zwei Detektionseinheiten verwendet. Auch ist es möglich, mehr als zwei Detektionseinheiten zur Erfassung der Isttrajektorie des Abtastbereiches der Erfassungseinheit einzusetzen.Especially are used to determine the Isttrajektorie the scanning of the Detection unit preferably used two detection units. Also it is possible to capture more than two detection units the Isttrajektorie the scanning range of the detection unit to use.
Vorzugsweise ist zur Erfassung der Isttrajektorie der Abtastbewegung keine Vorbereitungszeit zur Positionierung einer aus dem Stand der Technik bekannten statischen Prüfvorrichtung zur Ausrichtung der Erfassungseinheit erforderlich, wodurch eine Zeitersparnis und zusätzlich eine Kostenersparnis erzielt werden kann.Preferably is to prepare the Isttrajektorie the scanning movement no preparation time for Positioning of a known from the prior art static Testing device for aligning the detection unit required, thus saving time and additionally cost savings can be achieved.
Darüber hinaus können durch Anwendung des erfindungsgemäßen Verfahrens in vorteilhafter Weise unterschiedliche am Fahrzeug angeordnete Erfassungseinheiten ausgerichtet werden, ohne großen Aufwand zur Ausrichtung der jeweiligen Erfassungseinheit betreiben zu müssen.About that In addition, by applying the inventive Method advantageously different on the vehicle arranged detection units be aligned, without much effort to align to operate the respective detection unit.
