Description
Die Erfindung betrifft eine Fahrpedaleinrichtung für ein Kraftfahrzeug, mit einem kontaktlosen Linearsensor, der ein Cursorelement und ein Statorelement aufweist, und der mit einem Fahrpedalhebel verbunden ist, wobei das Cursorelement über ein Mitnahmeelement spielfrei mit dem Fahrpedalhebel gekoppelt ist.The invention relates to an accelerator pedal device for a motor vehicle, comprising a contactless linear sensor having a cursor element and a stator, and which is connected to an accelerator pedal lever, wherein the cursor element is coupled via a driving element without play with the accelerator pedal lever.
Eine Fahrpedaleinrichtung mit einem kontaktlosen Linearsensor ist aus der
Das Signal des kontaktlosen Sensors wird hierin durch die Stellung eines Cursors relativ zu einer Statorleiterplatte beeinflußt, wobei der Cursor bzw. das den Cursor tragende Cursorelement bei der bekannten Einrichtung mit dem Fahrpedalhebel verbunden ist. Dies kann in der Leerlaufstellung unter Umständen nachteilig sein. Wenn nämlich eine seitliche Kraft auf den Pedalarm einwirkt, findet aufgrund des immer vorhandenen Lagerspiels eine Verkippung des Pedalarms und damit des mit ihm verbundenen Cursors statt. Diese Verkippung entspricht einer normalen kleinen Bewegung des Pedalarms. Demzufolge wird sich auch das Sensorsignal verändern. Dies ist unerwünscht und aus Sicherheitsgründen zumeist auch nicht zulässig.The signal of the non-contact sensor is influenced herein by the position of a cursor relative to a stator printed circuit board, wherein the cursor or the cursor-carrying cursor element is connected in the known device with the accelerator pedal lever. This may be disadvantageous in the idle position under certain circumstances. If, in fact, a lateral force acts on the pedal arm, a tilting of the pedal arm and thus of the cursor associated with it takes place due to the ever-present clearance. This tilt corresponds to a normal small movement of the pedal arm. As a result, the sensor signal will also change. This is undesirable and for safety reasons usually not allowed.
Es ist die Aufgabe der Erfindung, eine Fahrpedaleinrichtung für ein Kraftfahrzeug, mit einem kontaktlosen Linearsensor zu schaffen, welche den vorgenannten Nachteil vermeidet.It is the object of the invention to provide an accelerator pedal device for a motor vehicle, with a contactless linear sensor, which avoids the aforementioned disadvantage.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Mitnahmeelement als ein mit dem Cursorelement verbundener Stift ausgebildet ist, der in eine Buchse innerhalb des oberen Hebelarms des Fahrpedalhebels eingesetzt ist und dass der Stift eine an der Buchse anliegende Fläche hat, die nach außen gewölbt ist.This object is achieved in that the driving element is formed as a connected to the cursor element pin which is inserted into a socket within the upper lever arm of the accelerator pedal lever and that the pin has a voltage applied to the socket surface which is curved outward.
Die Erfindung beseitigt das Problem, indem der Cursor von dem Pedalarm derartig entkoppelt wird, dass Verkippungen des Pedalarms keine Sensorsignaländerungen verursachen.The invention overcomes the problem by decoupling the cursor from the pedal arm such that tilts of the pedal arm do not cause sensor signal changes.
Dies wird dadurch realisiert, dass das Cursorelement derart ausgebildet ist, dass dessen Position direkt die Leerlaufstellung bestimmt. Ein Mitnahmeelement, welches spielfrei vorgespannt in den einen Abschnitt des Fahrpedalhebels greift, gleicht auftretende Verkippungen aus. Hierdurch kann die Lagerung des Pedalhebels sehr toleranzbehaftet und damit kostengünstig ausgeführt sein.This is realized in that the cursor element is designed such that its position directly determines the idle position. A driving element, which pre-stressed backlash engages in the one section of the accelerator pedal lever, compensates for occurring tilting. As a result, the storage of the pedal lever can be very tolerant and thus carried out inexpensively.
Auch ein sich eventuell über die Lebensdauer durch Verschleiß vergrößerndes Lagerspiel hat damit keinen Einfluß mehr auf das Sensorsignal. Es ist somit eine einfache und robuste Ausführung eines Fahrpedalgebers mit einem kontaktlosen Sensor möglich.Even a possibly over the life due to wear increasing bearing clearance thus has no influence on the sensor signal. It is thus a simple and robust design of an accelerator pedal encoder with a contactless sensor possible.
Im folgenden wird ein Ausführungsbeispiel der erfindungsgemäßen Fahrpedaleinrichtung anhand der Zeichnung dargestellt und näher erläutert. Es zeigen:In the following an embodiment of the accelerator pedal device according to the invention is illustrated and explained in more detail with reference to the drawing. Show it:
