Description
Die Erfindung bezieht sich auf eine Vorrichtung gemäß Oberbegriff Patentanspruch 1 sowie auf einen elektromotorischen Hilfsantrieb gemäß Oberbegriff Patentanspruch 10.The The invention relates to a device according to the preamble of the patent claim 1 and to an electric motor auxiliary drive according to the preamble Claim 10.
„Elektromotorische Hilfsantriebe für Fahrzeuge" im Sinne der Erfindung sind u.a. Scheibenwischerantriebe, elektromotorische Antriebe zum Verstellen von Fahrzeugsitzen, zum Öffnen und Schließen von Schiebedächern und/oder Fahrzeugverdecken usw."Electromotive Auxiliary drives for Vehicles "in the sense of the invention are i.a. Windscreen wiper drives, electromotive Drives for adjusting vehicle seats, for opening and closing sunroofs and / or vehicle concealment, etc.
Es ist bekannt, bei derartigen elektromotorischen Hilfsantrieben zur Steuerung des Motors und/oder zur Positionierung des Motors oder einer Antriebswelle des Antriebs, beispielsweise bei reversierenden Antrieben usw. an einer mit dem Motor oder mit der Antriebswelle umlaufenden Scheibe oder an einem entsprechenden Rad Permanentmagnete vorzusehen, die dann von wenigstens einem auf das Magnetfeld dieser Magnete ansprechenden Sensor, beispielsweise Hall-Sensor abgetastet werden, um so ein die Drehzahl und/oder Position bestimmendes Steuersignal zu erhalten.It is known in such electromotive auxiliary drives for Control of the motor and / or positioning of the motor or a drive shaft of the drive, for example, reversing Drives etc. at one with the motor or with the drive shaft rotating disc or on a corresponding wheel permanent magnets then provide at least one on the magnetic field of this Magnets responsive sensor, for example, Hall sensor scanned be such as a speed and / or position determining control signal to obtain.
Für die Bestimmung der Drehrichtung sind bisher wenigstens zwei Sensoren erforderlich.For the determination The direction of rotation so far at least two sensors are required.
Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung aufzuzeigen, mit der unter Beibehaltung der bisherigen Technik eine Bestimmung der Drehrichtung vereinfacht möglich ist. Zur Lösung dieser Aufgabe ist eine Vorrichtung entsprechend dem Patentanspruch 1 ausgebildet. Ein elektromotorischer Hilfsantrieb ist entsprechend dem Patentanspruch 10 ausgebildet.task the present invention is to show a device with the retention of the previous technique a provision the direction of rotation simplified possible is. To the solution This object is a device according to the claim 1 formed. An electric motor auxiliary drive is appropriate formed according to claim 10.
Bei der erfindungsgemäßen Vorrichtung, die beispielsweise Bestandteil eines elektromotorischen Hilfsantriebes ist, ist eine asymmetrische Verteilung der von dem wenigstens einen Sensor abgetasteten Segmente unterschiedlicher magnetischer Polarität vorgesehen.at the device according to the invention, for example, part of an electric motor auxiliary drive is an asymmetric distribution of the at least one Sensor sampled segments of different magnetic polarity provided.
Unter „asymmetrischer Verteilung" ist im Sinne der Erfindung insbesondere eine Verteilung der Segmente unterschiedlicher magnetischer Polarität in der Weise zu verstehen, daß sich in einer Abtastrichtung ein Verteilungsmuster dieser Segmente ergibt, welches unterschiedlich von dem Verteilungsmuster ist, welches bei einer Abtastung in einer entgegengesetzten Abtastrichtung erhalten wird.Under "asymmetric Distribution "is in the sense of the invention, in particular a distribution of the segments to understand different magnetic polarity in the way that yourself in a scanning direction gives a distribution pattern of these segments, which is different from the distribution pattern which is at a scan in an opposite scanning direction becomes.
Ein entscheidender Vorteil der Erfindung besteht darin, daß mit nur einem Sensor die Bestimmung in der Drehrichtung möglich ist, wodurch eine nicht unerhebliche konstruktive Vereinfachung und eine Reduzierung der Kosten für die Vorrichtung möglich sind.One decisive advantage of the invention is that with only a sensor is possible to determine in the direction of rotation, whereby a not insignificant structural simplification and a Reduction of costs for the device possible are.
