Vor diesem Hintergrund liegt der vorliegenden Erfindung nun die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zum einfachen und zuverlässigen Ermitteln der Rollrichtung eines Fahrzeugs bereitzustellen.In front In this background, the present invention is now the task underlying, a method and an apparatus for simple and reliable determination to provide the rolling direction of a vehicle.
Erfindungsgemäß wird diese Aufgabe durch ein Verfahren und eine Vorrichtung mit den Merkmalen der unabhängigen Patentansprüche gelöst.According to the invention this Task by a method and a device with the features the independent one claims solved.
Demgemäß ist bei einem Verfahren zum Ermitteln der Rollrichtung eines Fahrzeugs vorgesehen, dass die phasenverschobenen Drehzahlsignale von wenigstens an drei unterschiedlichen Rädern angeordneten Drehzahlsensoren empfangen werden. Die Phasenverschiebung der Drehzahlsignale wird einer ersten Rollrichtung zugeordnet. Eine Änderung der Phasenverschiebung der Drehzahlsignale wird als eine der ersten Rollrichtung entgegengesetzte Richtung ausgegeben.Accordingly, at a method for determining the rolling direction of a vehicle, that the phase-shifted speed signals of at least three different wheels arranged speed sensors are received. The phase shift The speed signals are assigned to a first rolling direction. A change in the Phase shift of the speed signals is considered one of the first Rolling direction opposite direction issued.
Die Vorrichtung zum Bestimmen der Rollrichtung eines Fahrzeugs weist wenigstens an drei unterschiedlichen Rädern angeordnete Drehzahlsensoren und eine Auswerteeinheit auf. Die Auswerteeinheit ordnet die Phasenverschiebung der von den Dreh zahlsensoren erzeugten Signale einer ersten Rollrichtung und eine Änderung in der Phasenverschiebung eine der ersten Rollrichtung entgegengesetzten Richtung zu.The Device for determining the rolling direction of a vehicle has at least on three different wheels arranged speed sensors and an evaluation unit. The evaluation unit orders the phase shift the signals generated by the rotational speed sensors of a first rolling direction and a change in the phase shift one of the first rolling direction opposite direction to.
Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche sowie der Beschreibung unter Bezugnahme auf die Zeichnung.advantageous Embodiments and developments of the invention are the subject the dependent claims and the description with reference to the drawing.
Die der vorliegenden Erfindung zugrunde liegende Idee besteht darin, an unterschiedlichen Rädern angeordnete Drehzahlsensoren für die Erkennung der Rollrichtung eines Fahrzeugs ("Vorwärts-/Rückwertserkennung") zu nutzen. Zur Erfassung der Rollrichtung eines Fahrzeugs bzw. der Drehrichtung der Räder ist es somit nicht erforderlich, mehrere Sensoren an einem Rad anzuordnen.The The idea underlying the present invention is that on different wheels arranged speed sensors for to use the recognition of the rolling direction of a vehicle ("forward / reverse detection"). to Detecting the rolling direction of a vehicle or the direction of rotation the wheels Thus, it is not necessary to arrange several sensors on a wheel.
Besonders vorteilhaft lässt sich die Erfindung im Zusammenhang mit einem Antiblockiersystem eines Kraftfahrzeugs nutzen. Dessen ohnehin vorhandenen Drehzahlsensoren können zur Erkennung der Rollrichtung des Fahrzeugs genutzt werden. Auf zusätzliche Sensoren kann verzichtet werden.Especially advantageous the invention in connection with an anti-lock braking system use of a motor vehicle. Its already existing speed sensors can be used to detect the rolling direction of the vehicle. On additional Sensors can be dispensed with.
Die Erfindung wird nachfolgend anhand der in den schematischen Figuren der Zeichnung angegebenen Ausführungsbeispiele näher erläutert. Es zeigt dabei:The Invention will be described below with reference to the schematic figures The drawings specified embodiments explained in more detail. It shows attended:
In allen Figuren der Zeichnung sind gleiche bzw. funktionsgleiche Elemente – sofern nichts Anderes angegeben ist – mit denselben Bezugszeichen versehen worden.In all figures of the drawing are the same or functionally identical elements - if nothing else is indicated - with the same reference numerals have been provided.

Der
Drehzahlsensor
Die Drehzahlsignale S1–S4 weisen jeweils zueinander eine Phasenverschiebung auf. Die Drehzahlsignale können den einzelnen Drehzahlsensoren und damit den Rädern zugeordnet werden. Der zeitliche Abstand der Drehzahlsignale der an den unterschiedlichen Rädern angeordneten Drehzahlsensoren zueinander oder, noch einfacher, die Reihenfolge der Drehzahlsignale definiert eine erste Rollrichtung R.The speed signals S 1 -S 4 each have a phase shift to each other. The speed signals can be assigned to the individual speed sensors and thus to the wheels. The time interval between the rotational speed signals of the rotational speed sensors arranged on the different wheels relative to each other or, more simply, the sequence of the rotational speed signals defines a first rolling direction R.
Die
Auswerteeinheit
Die Ermittlung der Rollrichtung erfolgt besonders zuverlässig, wenn zusätzlich ein eventueller, unterschiedlicher Schlupf der Räder in der Phasenbeziehung der Drehzahlsignale S1–S4 berücksichtigt und kompensiert wird.The determination of the rolling direction is particularly reliable, if in addition a possible, different slip of the wheels in the phase relationship of the speed signals S 1 -S 4 is taken into account and compensated.
Ein
Sensor
Bei einem Stillstand wird die Reihenfolge bzw. die Phasenlage oder Phasenbeziehung der Drehzahlsignale S1–S4 abgespeichert. Bewegt sich das Fahrzeug wieder, kann nach den ersten drei Impulsen, die von drei der vier Drehzahlsensoren stammen, festgestellt werden, ob sich die Rollrichtung geändert hat.At a standstill, the order or the phase relationship or phase relationship of the speed signals S 1 -S 4 is stored. If the vehicle moves again, it can be determined after the first three pulses, which come from three of the four speed sensors, whether the rolling direction has changed.

Obgleich die vorliegende Erfindung vorstehend anhand eines bevorzugten Ausführungsbeispiels beschrieben wurde, ist sie nicht darauf beschränkt, sondern auf vielfältige Art und Weise modifizierbar.Although the present invention above based on a preferred embodiment It is not limited to this, but in many ways and modifiable.
So sei die Erfindung nicht auf den in den vorstehenden Figuren dargestellten, speziellen Aufbau beschränkt. Vielmehr kann eben dieser auf beliebige Art und Weise modifiziert werden, ohne dass vom grundlegenden Prinzip der Erfindung abgewichen wird.So the invention is not limited to that shown in the preceding figures, limited special structure. Rather, just this can be modified in any way without departing from the basic principle of the invention.
Statt der Verwendung von als Hall-Sensoren ausgebildete Drehzahlsensoren können deren Funktion auch magnetoresistive Sensoren und/oder Induktiv-Sensoren verwendet werden, wenngleich sich Induktiv-Sensoren in der vorliegenden Ausführung eher schlechter eignen, da sie für ihre Funktion eine Mindestgeschwindigkeit erfordern.Instead of the use of designed as Hall sensors speed sensors can their function also magnetoresistive sensors and / or inductive sensors used, although inductive sensors in the present Execution rather worse suitable, since they are for their function require a minimum speed.
