Die Erfindung betrifft eine Pedaleinheit mit einem Pedal bzw. eine berührungsfreie Sensorik zur Erfassung einer Bewegung eines bzw. ein Verfahren zur Herstellung einer Pedaleinheit nach der Gattung der unabhängigen Patentansprüche.The invention relates to a pedal unit with a pedal or a non-contact sensor for detecting a movement of or a method for producing a pedal unit according to the preamble of the independent claims.

Aus DE 10 2005 033 179 A1 oder aus DE 10 2005 013 442 A1 ist es bekannt, dass ein Sensormodul in einer Hohlachse eines Pedalmoduls angeordnet sein kann, wobei Magnete um das Sensormodul herum in Aussparungen der Pedaleinheit angeordnet sind. Die Magnete drehen sich mit dem Pedal und damit um den Sensor herum.Out DE 10 2005 033 179 A1 or off DE 10 2005 013 442 A1 It is known that a sensor module can be arranged in a hollow axle of a pedal module, wherein magnets are arranged around the sensor module in recesses of the pedal unit. The magnets rotate with the pedal and thus around the sensor.

Die Offenlegungsschrift WO 01/63211 A1 betrifft eine Messvorrichtung zur berührungslosen Erfassung eines Drehwinkels, welche einen Magneten und ein magnetfeldempfinfliches Element umfasst. Das magnetfeldempfindliche Element ist ortsfest an einer feststehenden Welle angeordnet. Der Magnet ist an einem drehbaren Element (12) abgebracht, dessen Drehwinkel erfasst werden soll. Bei Betätigung des drehbaren Elements dreht sich der Magnet zusammen mit dem drehbaren Element um das magnetfeldempfindliche Element. Dadurch wird abhängig von der Magnetstellung am magnetfeldempfindlichen Element ein lineares Ausgangssignal erzeugt.The publication WO 01/63211 A1 relates to a measuring device for non-contact detection of a rotation angle, which comprises a magnet and a magnetic field-sensitive element. The magnetic field sensitive element is fixedly arranged on a fixed shaft. The magnet is mounted on a rotatable element (12) whose rotation angle is to be detected.

Offenbarung der ErfindungDisclosure of the invention

Die erfindungsgemäße Pedaleinheit bzw. die erfindungsgemäße berührungsfreie Sensorik zur Erfassung einer Bewegung eines Pedals bzw. die erfindungsgemäße Gebereinrichtung bzw. das erfindungsgemäße Sensorelement bzw. das erfindungsgemäße Verfahren zur Herstellung einer Pedaleinheit haben demgegenüber den Vorteil, dass nunmehr der Luftspalt, der durch den Zusammenbau der Pedaleinheit zwischen dem Sensorelement und dem Geber entsteht, sich in Richtung der Hohlachse erstreckt bzw. ausgerichtet ist Damit ist der Luftspalt koaxial zur Hohlachse ausgebildet. Dies ermöglicht eine einfache Herstellung der erfindungsgemäßen Pedaleinheit bzw. der berührungsfreien Sensorik und ermöglicht die effektive Kapselung dieses Luftspalts gegen das Eindringen von Fremdkörpern wie zum Beispiel Metallspäne Damit kann eine Beeinträchtigung sowohl der Mechanik als auch des Sensorsignals, was jeweils abhängig vom physikalischen Sensorprinzip ist, vermieden werden. Ein weiterer Vorteil dieses Einbauorts liegt darin, dass eine bewusste Manipulation des Sensors deutlich erschwert oder eine versehentliche Beschädigung des Sensors im Fußraum, z. B. durch einen abrutschenden Fuß ausgeschlossen werden kann. Weiterhin ermöglicht der Einbau in der erfindungsgemäßen Art in der Hohlachse, dass in dieser starren Hohlachse die Toleranzauswirkungen der Pedaleinheit am Geringsten sind, so dass eine Sensorintegration an dieser Stelle ohne zusätzliche mechanische Führung im Sensor ohne negativen Einfluss auf das Sensorsignal realisiert werden kann. Das Sensorelement kann erfindungsgemäß mit geringen akzeptablen Toleranzen berührungslos vor dem Geber montiert werden. Dadurch können etablierte, verfügbare und preisgünstige sogenannte Wellenendewinkelsensoren eingesetzt werden. Diese Integration erlaubt die Verwendung der geometrisch-identischen Geberwelle und dem Sensor sowohl für Links- und Rechtslenkerpedale. Eine Varianz zwischen verschiedener Pedaltypen verschiedener Fahrzeuge oder Plattformen kann so durch Anpassung lediglich der Geberwelle realisiert werden, ohne die berührungsfreie Sensorik geometrisch zu verändern.The pedal unit according to the invention or the contactless sensor according to the invention for detecting a movement of a pedal or the transducer device according to the invention or the inventive method for producing a pedal unit have the advantage that now the air gap caused by the assembly of the pedal unit arises between the sensor element and the encoder, extends in the direction of the hollow axis and is aligned so that the air gap is formed coaxially to the hollow shaft. This allows a simple production of the pedal unit according to the invention or the non-contact sensor and allows the effective encapsulation of this Air gap against the ingress of foreign bodies such as metal chips Thus, an impairment of both the mechanics and the sensor signal, which is dependent on the physical sensor principle, can be avoided. Another advantage of this installation location is that a deliberate manipulation of the sensor makes it much more difficult or accidental damage to the sensor in the footwell, z. B. can be excluded by a slipping foot. Furthermore, the incorporation in the type according to the invention in the hollow axle allows the tolerance effects of the pedal unit to be least in this rigid hollow shaft, so that sensor integration can be realized at this point without additional mechanical guidance in the sensor without negative influence on the sensor signal. The sensor element can be mounted according to the invention with low acceptable tolerances without contact in front of the encoder. As a result, established, available and inexpensive so-called shaft end angle sensors can be used. This integration allows the use of the geometrically identical encoder shaft and sensor for both left and right hand pedals. A variance between different types of pedals of different vehicles or platforms can thus be realized by adapting only the encoder shaft, without geometrically changing the non-contact sensors.

Eine Pedaleinheit ist vorliegend die Einheit, die in das Fahrzeug eingebaut wird, um das Pedal zu montieren. Die Pedaleinheit umfasst daher einen starren Teil, der als Lagebock bezeichnet wird, und das bewegliche Pedal. Erfindungsgemäß ist auch die berührgungsfreie Sensorik in dieser Pedaleinheit vorgesehen. Das Pedal kann da beispielsweise ein Bremspedal oder ein Gas- oder Kupplungspedal sein. Die Pedaleinheit und auch das Pedal sind im Falle von Bremspedalen meist aus Stahl und im Falle von Kupplungs- oder Gaspedalen meist aus Kunststoff hergestellt. Das Pedal ist um eine Hohlachse des Lagebocks beweglich gelagert, um sich um diese Hohlachse zu drehen. Die berührungsfreie Sensorik, die beispielsweise aus einem Gebermagnet als dem Geber, der auch mehrere Einzelmagneten umfassen kann, und einem Sensorelement zur Erfassung des Magnetfelds üblicherweise besteht, dient zur Erfassung der Bewegung des Pedals um diese Hohlachse. Mit Bewegung ist vorliegend eine Dreh- und/oder Linearbewegung des Pedals gemeint.A pedal unit in the present case is the unit that is installed in the vehicle to mount the pedal. The pedal unit therefore comprises a rigid part, which is referred to as a positional block, and the movable pedal. According to the invention also Berührgungsfreie sensor is provided in this pedal unit. The pedal can be there for example a brake pedal or a gas or clutch pedal. The pedal unit and the pedal are usually made of steel in the case of brake pedals and in the case of clutch or accelerator pedals usually made of plastic. The pedal is movably mounted about a hollow axis of the jack to rotate about this hollow axle. The non-contact sensor system, which typically consists, for example, of a transmitter magnet as the encoder, which may also comprise a plurality of individual magnets, and a sensor element for detecting the magnetic field, serves to detect the movement of the pedal about this hollow axle. By movement is meant in the present case a rotary and / or linear movement of the pedal.

Unter dem Geber wird wie bereits angegeben üblicherweise ein Gebermagnet verstanden. Es sind jedoch auch andere Sensorprinzipien möglich, beispielsweise eine optische Sensorik, wobei im sichtbaren und/oder unsichtbaren Licht gearbeitet werden kann, eine Ultraschallsensorik oder die Ausnutzung elektromagnetischer Wellen. Weiterhin ist auch die Verwendung eines Sensors auf Basis von Wirbelstrom möglich.As already stated, the encoder is usually understood to mean a transmitter magnet. However, other sensor principles are also possible, for example an optical sensor system in which visible and / or invisible light can be used, ultrasound sensors or the utilization of electromagnetic waves. Furthermore, the use of a sensor based on eddy current is possible.

Das Sensorelement ist bei der der Verwendung eines Gebermagneten üblicherweise ein Hallsensor oder ein sogenannter AMR-Sensor, der ein anisotropes magnetoresistives Sensorelement beinhaltet. Anisotrope magnetoresistive Sensorelemente sind Dünnschichtsensoren aus einem feromagnetischen Material, beispielsweise Permaloi, deren Widerstand gegenüber einem elektrischen Stromfluss von dem Winkel zwischen einer Stromrichtung des Stromflusses und einer Magnetfeldrichtung in der Ebene der Dünnschicht abhängt. Auch sogenannte GMR (giant magneto resistive)-Sensoren können vorliegend verwendet werden. Das Sensorelement umfasst nicht nur die Sensorik zur Erfassung des Magnetfelds, sondern auch einen entsprechenden Auswertechip, der mit dem Sensorelement integriert sein kann. Dieser Auswertechip ermöglicht dann die Abgabe des Sensorsignals zur weiteren Auswertung, wobei dieser Auswertechip bereits eine Vorauswertung durchführen kann. Wird ein anderes Sensorprinzip verwendet, ist das Sensorelement entsprechend gestaltet: bei einer optischen Sensorik wird ein geeigneter Lichtempfänger als Sensorelement, bei einer Ultraschallsensorik ein Ultraschallwandler und bei der Verwendung elektromagnetischer Wellen ein geeigneter Funkempfänger verwendet.In the case of the use of a transmitter magnet, the sensor element is usually a Hall sensor or a so-called AMR sensor, which contains an anisotropic magnetoresistive sensor element. Anisotropic magnetoresistive sensor elements are thin film sensors made of a feromagnetic material, such as Permaloi, whose resistance to electrical current flow depends on the angle between a current direction of the current flow and a magnetic field direction in the plane of the thin film. Also so-called GMR (giant magnetoresistive) sensors can be used here. The sensor element not only includes the sensors for detecting the magnetic field, but also a corresponding evaluation chip, which can be integrated with the sensor element. This evaluation chip then enables the delivery of the sensor signal for further evaluation, wherein this evaluation chip can already carry out a preliminary evaluation. If another sensor principle is used, the sensor element is designed accordingly: in an optical sensor system, a suitable light receiver is used as the sensor element, in an ultrasonic sensor system an ultrasonic transducer and in the case of the use of electromagnetic waves a suitable radio receiver.

Der Luftspalt zwischen dem Geber und dem Sensorelement ist typischerweise zwischen 1 und 4 mm. Der Luftspalt ist vorliegend notwendig, da sich der Geber mit der Welle und dem Pedal gegenüber dem Sensorelement dreht. Diese Drehung führt im Falle einer Magnetfeldsensorik zu einer Magnetfeldänderung und ist durch das Sensorelement erfassbar, so dass die Drehung gemessen werden kann, um dann weiterverarbeitet zu werden als Fahrerwunsch.The air gap between the transmitter and the sensor element is typically between 1 and 4 mm. The air gap is presently necessary because the encoder rotates with the shaft and the pedal relative to the sensor element. This rotation leads in the case of a magnetic field sensor to a magnetic field change and can be detected by the sensor element, so that the rotation can be measured, in order to be further processed as a driver's request.

Die berührungsfreie Sensorik ist vorzugsweise eine Magnetfeldsensorik, die das Sensorelement und den Gebermagneten mit der Welle aufweist. Berührungsfrei heisst vorliegend, dass keine unmittelbare kraft- oder form- oder stoffschlüssige Verbindung zwischen dem Geber und dem Sensorelement besteht, sondern der Geber und das Sensorelement sind durch einen Luftspalt getrennt.The non-contact sensor is preferably a magnetic field sensor which has the sensor element and the encoder magnet with the shaft. contactless In the present case, this means that there is no direct positive or positive or material connection between the transmitter and the sensor element, but the transmitter and the sensor element are separated by an air gap.

Die Welle, auf die der Geber angeordnet ist, ist vorzugsweise aus einem nichtmagnetischen Metall hergestellt. Die Welle wird in der Hohlachse geführt und gelagert. Die Führung erreicht man beispielsweise durch eine entsprechende Metallbuchse, wobei anstatt Metall auch andere Materialien verwendbar sind. Die Führung kann alternativ durch eine entsprechende Auslegung der Hohlachse und der Welle erreicht werden. Weiterhin ist eine Führung auf dem Aussendurchmesser der Hohlwelle denkbar.The shaft on which the encoder is arranged is preferably made of a non-magnetic metal. The shaft is guided and stored in the hollow axle. The leadership can be achieved, for example, by a corresponding metal bushing, with other materials can be used instead of metal. The guide can alternatively be achieved by a corresponding design of the hollow shaft and the shaft. Furthermore, a guide on the outside diameter of the hollow shaft is conceivable.

Das Sensorelement weist Mittel zur Befestigung an einem Ende der Hohlachse der Pedaleinheit auf, so dass das Sensorelement nur über einen Luftspalt vom Geber in der Hohlachse getrennt ist. Üblicherweise wird damit das Sensorelement auf einem Ende der Hohlachse, an dem sich der Geber befindet, auf die Pedaleinheit, beispielsweise auf dem Lagerbock oder der Hohlachse selbst aufgeschraubt. Diese Mittel sind üblicherweise, wie angegeben, Schraubverbindungen; es sind jedoch auch andere kraft- oder formschlüssige oder stoffschlüssige Verbindungen möglich.The sensor element has means for attachment to one end of the hollow axle of the pedal unit, so that the sensor element is separated from the transmitter in the hollow axle only via an air gap. Usually, the sensor element is thus screwed onto the pedal unit, for example on the bearing block or the hollow axle itself, on one end of the hollow shaft on which the encoder is located. These agents are usually, as indicated, threaded connections; However, other non-positive or positive or cohesive connections are possible.

Durch die in den abhängigen Ansprüchen angegebenen Maßnahmen und Weiterbildungen sind weitere vorteilhafte Ausprägungen der erfindungsgemäßen Pedaleinheit, berührungsfreien Sensorik, Gebereinrichtung und des Sensorelements sowie des Verfahrens zur Herstellung der Pedaleinheit möglich.The measures and developments specified in the dependent claims further advantageous embodiments of the pedal unit according to the invention, non-contact sensors, transducer device and the sensor element and the method for producing the pedal unit are possible.

Es ist von Vorteil, dass der Geber auf der Welle angeordnet ist, die in der Hohlachse eingeführt ist, wobei die Welle mit dem Pedal derart gekoppelt ist, dass der Geber durch das Pedal bewegt wird. Dafür kann insbesondere ein Mitnehmerelement verwendet werden, das beispielsweise in die Welle eingepresst ist und am Pedal angeschraubt ist. Beispielsweise kann dafür ein sogenanntes Mitnehmerblech verwendet werden. Das Mitnehmerblech befindet sich auf derselben Seite oder auf der gegenüberliegenden Seite der Welle, an der der Geber angeordnet ist. Der Geber kann dabei auf der Welle aufgeklebt, eingepresst oder durch eine stoffschlüssige Verbindung oder kraftschlüssige Verbindung oder formschlüssige Verbindung befestigt sein. Der Geber ist damit auf der Stirnseite der Welle angeordnet gegenüber von dem Sensorelement nur getrennt durch den Luftspalt. Der Geber kann in einer Ausnehmung der Welle angeordnet sein und beispielsweise nur teilweise über die Welle hinausragen.It is advantageous that the encoder is arranged on the shaft, which is inserted in the hollow axle, wherein the shaft is coupled to the pedal such that the encoder is moved by the pedal. For this purpose, in particular, a driver element can be used, which is for example pressed into the shaft and screwed to the pedal. For example, a so-called drive plate can be used for this purpose. The drive plate is located on the same side or on the opposite side of the shaft on which the encoder is arranged. The encoder can be glued on the shaft, pressed or by a cohesive connection or non-positive Attached connection or positive connection. The encoder is thus arranged on the end face of the shaft opposite the sensor element only separated by the air gap. The encoder can be arranged in a recess of the shaft and, for example, only partially protrude beyond the shaft.

Vorteilhafter Weise kann die Kapselung des Luftspalts gegen das Eindringen der Fremdkörper durch folgende Maßnahmen erreicht werden: Durch eine entsprechende Gestaltung des Gehäuses des Sensorelements oder des Pedalblocks beziehungsweise Adapter oder Zwischenplatte zwischen Sensorelement samt Gehäuse und Pedaleinheit (Lagerbock).Advantageously, the encapsulation of the air gap against the ingress of foreign bodies can be achieved by the following measures: By appropriate design of the housing of the sensor element or the pedal block or adapter or intermediate plate between the sensor element together with housing and pedal unit (bracket).
