Abstract
Es wird eine Fahrpedalvorrichtung mit einem Pedalelement (3) sowie einer Gegenkraftvorrichtung mit einem Torquemotor (2) vorgestellt, wobei die Abgangswelle des Torquemotors mit einem Untersetzungsgetriebe (1, 4) gekoppelt ist, an welchem ein Mitnehmerelement (14) angeordnet ist, welches zumindest in eine Bewegungsrichtung des Pedalelements wirkt.It is an accelerator pedal device with a pedal element (3) and a counter force device with a torque motor (2) presented, wherein the output shaft of the torque motor with a reduction gear (1, 4) is coupled to which a driver element (14) is arranged, which at least in a direction of movement of the pedal element acts.
Description
Die Erfindung betrifft eine Fahrpedalvorrichtung mit einem Pedalelement sowie einer Gegenkraftvorrichtung dem Oberbegriff von Anspruch 1. The invention relates to an accelerator pedal device with a pedal element and an opposing force device to the preamble of
Gegenkraftvorrichtungen dienen zur Erzeugung haptischer Rückkopplung an den Fahrer des Kraftfahrzeugs über die Fahrpedalvorrichtung, insbesondere zur Geschwindigkeit- oder Abstandsregelung. Eine solche Gegenkraftvorrichtung kann mit einem Torquemotor ausgestattet sein, da dieser als Langsamläufer ein hinreichendes Drehmoment für eine entsprechende haptischer Rückkopplung aufweist und für Fahrpedalvorrichtungen üblicherweise nur ein definierter Schwenkwinkel erforderlich ist, welcher durch Torquemotoren üblicherweise erreicht wird.Counter force devices are used to generate haptic feedback to the driver of the motor vehicle via the accelerator pedal device, in particular for speed or distance control. Such an opposing force device can be equipped with a torque motor, since it has a sufficient torque for a corresponding haptic feedback as a low-speed rotor and for accelerator pedal devices usually only a defined pivot angle is required, which is usually achieved by torque motors.
Eine solche Fahrpedalvorrichtung ist beispielsweise aus der
Die Aufgabe der vorliegenden Erfindung ist es, eine Fahrpedalvorrichtung der eingangs beschriebenen Art weiter zu verbessern.The object of the present invention is to further improve an accelerator pedal device of the type described above.
Diese Aufgabe wird durch die Merkmale der unabhängigen Ansprüche gelöst. Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen, wobei auch Kombinationen und Weiterbildungen einzelner Merkmale miteinander denkbar sind.This object is solved by the features of the independent claims. Advantageous developments of the invention will become apparent from the dependent claims, and combinations and developments of individual features are conceivable with each other.
Ein wesentlicher Gedanke der Erfindung besteht darin, dass die Abgangswelle des Torquemotors mit einem Untersetzungsgetriebe gekoppelt ist, an welchem ein Mitnehmerelement angeordnet ist, welches zumindest in eine Bewegungsrichtung des Pedalelements wirkt. Durch das Untersetzungsgetriebe, also eine Getriebe mit einer Untersetzung, also ein Abgangsdrehzahl, welche um dem Übersetzungsverhältnis entsprechendes mathematisches Vielfaches kleiner ist als die Eingangsdrehzahl, wird die Kraft am Mitnehmerelement erhöht und der dafür erforderliche Verstellweg am Mitnehmerelement und damit der Einfluss der Gegenkrafteinrichtung auf die Position des Pedalelements reduziert.An essential idea of the invention is that the output shaft of the torque motor is coupled to a reduction gear, on which a driver element is arranged, which acts at least in a direction of movement of the pedal element. Through the reduction gear, so a transmission with a reduction, so a output speed, which is smaller than the input speed corresponding to the gear ratio mathematical multiple, the force is increased at the driver and the required adjustment path on the driver element and thus the influence of the counter-force to the position the pedal element is reduced.
Als Untersetzungsgetriebe ist in einer ersten bevorzugten Ausgestaltung ein Planetengetriebe vorgesehen. Dieses Planetengetriebe kann unmittelbar auf die Welle des Torquemotor und axial zur Drehwelle des Pedals angeordnet werden. Alternativ dazu ist aber auch beispielsweise ein Stirnradgetriebe möglich.As a reduction gear, a planetary gear is provided in a first preferred embodiment. This planetary gear can be placed directly on the shaft of the torque motor and axially to the rotary shaft of the pedal. Alternatively, but also, for example, a spur gear possible.
Vorzugsweise greift das Mitnehmerelement in ein Langloch im Pedalelement ein und liegt dort durch die Wirkung eine Rückstellfeder an einer Seite des Langlochs an, kann jedoch insbesondere bei einem Festfahren des Torquemotors das Pedalelement innerhalb des Langlochs weiterbewegt und insbesondere das Gaspedal immer in die Nullstellung zurückgenommen werden. Preferably, the driver element engages in a slot in the pedal element and is there by the action of a return spring on one side of the slot, but in particular when the torque motor stuck the pedal element within the slot further moves and in particular the accelerator pedal are always returned to the zero position.
So ist es vorzugsweise auch möglich, dass das Mitnehmerelement unmittelbar, also insbesondere ohne Zwischenschaltung einer Kupplung oder weiterer Federn, auf das Pedalelement wirkt.Thus, it is preferably also possible for the driver element to act on the pedal element directly, that is to say in particular without the interposition of a clutch or other springs.
