Abstract
Description
Die vorliegende Erfindung betrifft ein Fahrpedal für Kraftfahrzeuge, wobei eine durch eine entsprechende Betätigungskraft herbeigeführte Lageänderung des Fahrpedals gegenüber seiner Ausgangslage entgegen einer Rückstellkraft einer Rückstellfeder zu einer Erhöhung der Antriebskraft des Motors führt und bei nachlassender Betätigungskraft die Rückstellkraft der Rückstellfeder das Fahrpedal in Richtung seiner Ausgangslage zurückbefördert.The present invention relates to an accelerator pedal for motor vehicles, wherein a brought about by a corresponding actuation force change in position of the accelerator pedal against its initial position against a restoring force of a return spring to increase the driving force of the engine and with decreasing actuation force, the restoring force of the return spring, the accelerator pedal in the direction of its initial position ,
Aus der
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Fahrpedal darzustellen, das möglichst einfach aufgebaut ist, wenig Bauraum benötigt und dabei dem Fahrzeugführer haptische Informationen zur Verfügung stellen kann.The present invention is therefore based on the object to represent an accelerator pedal that is as simple as possible, requires little space and can provide the vehicle driver haptic information available.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Dabei ist ein fremdansteuerbarer Aktuator vorgesehen, der derart mit der Rückstellfeder zusammenwirkt, dass deren Rückstellkraft auf das Fahrpedal veränderbar ist. Entscheidender Gedanke ist es, die ohnehin vorhandene Rückstellfeder so zu beeinflussen, dass deren Rückstellkraft verändert wird und der Fahrzeugführer eine haptische Rückmeldung erhält.This object is solved by the features of
Vorteilhafte Weiterbildungen sind den Unteransprüchen entnehmbar.Advantageous developments are the dependent claims.
So ist in einer bevorzugten Weiterbildung des Erfindungsgegenstandes vorgesehen, dass sich die Rückstellfeder einerseits an einem Arm des Pedalhebels des Fahrpedals und andererseits an einer verschiebbaren Abstützplatte abstützt.Thus, it is provided in a preferred development of the subject invention that the return spring is supported on the one hand on an arm of the pedal lever of the accelerator pedal and on the other hand on a displaceable support plate.
Die Abstützplatte ist vom Aktuator linear verschiebbar und die Rückstellkraft der Rückstellfeder auf das Fahrpedal ist variierbar.The support plate is linearly displaceable by the actuator and the restoring force of the return spring to the accelerator pedal is variable.
Bei einer besonders vorteilhaften Weiterbildung des Erfindungsgegenstands ist vorgesehen, dass vom Aktuator ein Kraftübertragungsglied betätigt wird, das mit einem Kniehebel zusammenwirkt, wobei sich der Kniehebel einerseits fahrzeugaufbauseitig abstützt und andererseits mit der Abstützplatte verbunden ist und diese bei Betätigung des Kniehebels linear verschiebt.In a particularly advantageous embodiment of the subject invention, it is provided that the actuator a force transmission member is actuated, which cooperates with a toggle, the toggle is supported on the one hand vehicle body side and on the other hand connected to the support plate and this moves linearly upon actuation of the toggle lever.
Der Aktuator ist entweder als elektromechanischer Aktuator oder als elektromagnetischer Aktuator ausgebildet.The actuator is designed either as an electromechanical actuator or as an electromagnetic actuator.
Bei einer weiteren bevorzugten Ausführungsform wird der elektromagnetische Aktuator durch einen elektrisch ansteuerbaren Hubmagneten realisiert, dessen Anker die Abstützplatte linear verschiebt. Um die Abstützplatte auch bei ausgeschaltetem Hubmagneten in der vom Hubmagneten erzeugten Position zu halten, ist ein elektromechanischer Aktuator vorgesehen, der die Abstützplatte in seiner Position hält.In a further preferred embodiment, the electromagnetic actuator is realized by an electrically controllable lifting magnet whose armature linearly displaces the support plate. In order to keep the support plate even when the solenoid is turned off in the position generated by the solenoid, an electromechanical actuator is provided which holds the support plate in position.
Bei einem alternativen Ausführungsbeispiel wird der Aktuator durch eine Leistungselektronik gebildet, die mit der Rückstellfeder elektrisch verbunden ist. Die Rückstellfeder ist einem Material gefertigt, dessen physikalische Eigenschaften durch Anlegen eines elektrischen Feld veränderbar sind.In an alternative embodiment, the actuator is formed by a power electronics, which is electrically connected to the return spring. The return spring is made of a material whose physical properties can be changed by applying an electric field.
Die Rückstellfeder ist als Torsionsfeder oder Druckfeder ausgebildet.The return spring is designed as a torsion spring or compression spring.
Vorzugsweise werden die Aktuatoren von einer Steuereinheit angesteuert, um die Position der Abstützplatte nach Maßgabe der Steuereinheit zu verändern.Preferably, the actuators are controlled by a control unit to change the position of the support plate in accordance with the control unit.
Die Erfindung wird nachfolgend anhand dreier Ausführungsbeispiele im Zusammenhang mit der beiliegenden Zeichnung näher erläutert. In der Zeichnung zeigen:The invention will be explained in more detail below with reference to three embodiments in conjunction with the accompanying drawings. In the drawing show:
