Pedal mit einem Aktor zum Erzeugen eines haptisch wahrnehmbaren Signals Pedal with an actuator for generating a haptic perceptible signal
Die Erfindung betrifft ein Pedal gemäß dem Oberbegriff von Anspruch 1. Pedale in Fahrzeugen, insbesondere das Gaspedal, werden zunehmend mit einem Aktor versehen, um dem Fahrer des Fahrzeuges ein haptisch wahrnehmbares Signal bei bestimmten Verkehrssituationen, beispielsweise dem Unterschreiten eines Mindestabstandes oder einem anstehenden Gangwechsel oder einer unökonomischen Fahrweise, beispielsweise dem Abweichen von einem optimalen Geschwindigkeit-oder Drehmomenten Bereich zu signalisieren. The invention relates to a pedal according to the preamble of claim 1. Pedals in vehicles, especially the gas pedal, are increasingly provided with an actuator to the driver of the vehicle a haptic perceptible signal in certain traffic situations, such as falling below a minimum distance or a pending gear change or an uneconomic driving style, for example, to signal the departure of an optimal speed or torque range.
Dazu werden so genannte „Force-Feedback-Pedale", wie beispielsweise in der EP 1375233 B1 oder DE 10 2009 041 361 A1 , üblicherweise mit elektrischen Aktoren versehen, welche auf Basis von rotierenden Elektromotoren oder aber elektromagnetischen Linearantrieben arbeiten. Solche Aktoren ermöglichen eine gezielte Steuerung der Gegenkraft-Kennlinie, sind jedoch entsprechend aufwendig, teuer und weisen einen nicht unerheblichen Stromverbrauch auf.  For this purpose, so-called "force feedback pedals", as for example in EP 1375233 B1 or DE 10 2009 041 361 A1, are usually provided with electric actuators which operate on the basis of rotating electric motors or else electromagnetic linear drives Control of the drag characteristic curve, however, are correspondingly expensive, expensive and have a significant power consumption.
Darüber hinaus sind beispielsweise aus der DE 100 26 048 C2 oder DE 202010007324 U1 Pedale mit einer Vibrationseinrichtung bekannt, welche beispielsweise auf Basis piezoelektrischer Aktoren immer noch optisch wahrnehmbare Signale am Pedal erzeugen, ohne dass jedoch die Stärke und Arbeitsamplitude einer solchen Vibrationseinrichtung dafür ausreichen würde, eine direkte Gegenkraft-Rückkopplung über den Arbeitsbereich des Pedal hinweg zu ermöglichen.  In addition, for example from DE 100 26 048 C2 or DE 202010007324 U1 pedals with a vibration device are known, which still produce optically perceptible signals on the pedal, for example based on piezoelectric actuators, but without the strength and working amplitude of such a vibration device would be sufficient for to allow direct drag feedback across the work area of the pedal.
Diesen wie auch der aus der DE 20 2013 103 01 1 U1 bekannten Fahrzeugpedalanordnung mit einem Antrieb für eine haptische Rückmeldung ist jedoch gemeinsam, dass sich der jeweilige Antrieb zwingend auf dem Pedalarm bzw. Gehäuse unter der Fußablage abstützen muss, um die Vibrationen zur Fußablage hin einkoppeln zu können. Wenngleich in der reinen Prinzipskizze der DE 20 2013 103 01 1 U1 nicht näher ausgeführt, ist doch sowohl für den antriebenden Motor als auch der Widerlager des Stößels eine starre Befestigung am Pedalarm bzw. Gehäuse unter der Fußablage erforderlich. Analoges gilt auch für die DE 100 26 048 C2, deren Vibrationseinrichtung zwar ausschließlich am Pedal, dort aber eben entsprechend abgestützt sein muss. Die Aufgabe der vorliegenden Erfindung ist es, ein solches Pedal so weiterzubilden, dass es kostengünstig zu realisieren ist und eine verbesserte Wahrnehmbarkeit des haptischen Signals aufweist. 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. However, this as well as the vehicle pedal arrangement with a drive for haptic feedback known from DE 20 2013 103 01 1 U1 has in common that the respective drive must necessarily be supported on the pedal arm or housing under the footrest in order to move the vibrations towards the footrest to be able to couple. Although not described in detail in the pure schematic diagram of DE 20 2013 103 01 1 U1, yet a rigid attachment to the pedal arm or housing under the footrest is required both for the driving motor and the abutment of the plunger. The same applies to DE 100 26 048 C2, the vibration device, although only on the pedal, but there just must be supported accordingly. The object of the present invention is to develop such a pedal so that it is inexpensive to implement and has an improved visibility of the haptic signal. 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.
Grundgedanke der Erfindung ist dabei, dass der bewegliche Teil der Bedienplatte als eine schwingfähige Membran ausgebildet ist, welche an zumindest einem Ende am Pedalgrundkörper schwingungsfähig bzw. auslenkbar gelagert ist und der Aktor in einem Hohlraum des Pedalgrundkörpers ausschließlich an der Membran befestigt ist.  The basic idea of the invention is that the movable part of the control panel is designed as a vibrating diaphragm, which is mounted on at least one end of the pedal body oscillatory or deflectable and the actuator is mounted in a cavity of the Pedalgrundkörpers exclusively on the membrane.
Dadurch ist die Membran mit dem Aktor von dem restlichen Pedalgrundkörper weitgehend entkoppelt und kann die Schwingungsenergie über die Membran gut an den Fahrerfuß weitergeben.  As a result, the membrane with the actuator is largely decoupled from the rest of the pedal body and can pass the vibration energy across the membrane well to the driver's foot.
Der Aktor wird dabei mit Schwingungen einer vorgegebenen Anregungsfrequenz angeregt und sind die Eigenfrequenz der Membran und die Anregungsfrequenz des Aktors so zueinander ausgelegt, dass sich die Anregungsschwingungen zumindest teilweise überlagern, die Schwingung sich also entsprechend verstärkt, es also beispielsweise zu einer Resonanz, also Überlagerung der Schwingungen kommt.  The actuator is thereby excited with vibrations of a predetermined excitation frequency and the natural frequency of the membrane and the excitation frequency of the actuator are designed to each other so that the excitation vibrations at least partially overlap, so the vibration amplifies accordingly, so it for example to a resonance, ie superimposition of the Vibrations come.
Dazu weist der Hohlraum vorzugsweise ein Übermaß gegenüber dem Aktor bzw. auch der Membran auf, so dass die Membran mit dem Aktor im Hohlraum frei schwingungsfähig ist. Insbesondere ist der Hohlraum also so tief, dass Membran und Aktor nicht auf dem gegenüberliegenden Boden des Hohlraums aufschlagen.  For this purpose, the cavity preferably has an excess in relation to the actuator or the membrane, so that the membrane with the actuator in the cavity is free to vibrate. In particular, the cavity is so deep that the membrane and actuator do not hit the opposite bottom of the cavity.
Die Membran kann aus einem dünnen Metall oder aber vorzugsweise aus einem Elastomer geformt sein, und so beispielsweise in einem Zwei- Komponenten- Spritzgussprozess beispielsweise mit dem Pedalgrundkörper zusammen gefertigt und der Aktor durch eine entsprechende Öffnung hindurch im Hohlraum an der Membran befestigt werden. Die Enden sind dabei entsprechend verjüngt, um eine möglichst weitgehende Entkopplung zu erreichen, andererseits durch die Wahl geeigneter Materialien so gestaltet, dass die Membran auch unter Schwingungsbelastung nicht vom Pedalgrundkörper abreißt.  The membrane may be formed of a thin metal or, preferably, of an elastomer, and thus, for example, in a two-component injection molding process, for example, with the pedal body made together and the actuator to be secured through a corresponding opening in the cavity on the membrane. The ends are correspondingly tapered in order to achieve the greatest possible decoupling, on the other hand designed by the choice of suitable materials so that the membrane does not break even under vibration stress from the pedal body.
In einer weiteren bevorzugten Ausgestaltung ist die Membran zum Fahrerfuß hin konvex gewölbt. Durch Auflegen des Fahrerfußes kann damit die Membran unter Spannung gebracht und so das haptische Signal noch besser in den Fahrerfuß ein gekoppelt werden. Vorzugsweise weist der Aktor darüber hinaus eine flexible oder drahtlose elektrische Energiezufuhr auf. In a further preferred embodiment, the membrane is convexly curved toward the driver's foot. By placing the driver's foot can thus brought the membrane under tension and so the haptic signal even better coupled into the driver's foot. Preferably, the actuator further comprises a flexible or wireless electrical power supply.
Die Erfindung wird nachfolgend anhand von Ausführungsbeispielen unter Bezugnahme auf die Figuren näher erläutert.  The invention will be explained in more detail by means of embodiments with reference to the figures.
Figur 1 zeigt dabei eine hängende Ausführung des Pedals mit einem Pedalgrundkörper 1 und einer als Membran 2 ausgestalteten Bedienplatte, welche hier vorzugsweise an beiden gegenüberliegenden Enden, zumindest aber an einem Ende, schwingungsfähig bzw. auslenkbar gelagert ist.  FIG. 1 shows a suspended embodiment of the pedal with a basic pedal body 1 and a control panel configured as a membrane 2, which is preferably mounted so that it can vibrate or deflect at two opposite ends, but at least at one end.
Der Aktor 4 ist in einem Hohlraum 3 des Pedalgrundkörpers ausschließlich an der Membran 2 befestigt. In dem sich der Aktor 4 nicht auf dem Pedalgrundkörper 1 abstützt und die Membran 2 an ihren Enden 5 schwingungsfähig gelagert ist, wird die Energie des Aktors 4 über die Membran 2 weitestgehend unmittelbar an den Fahrerfuß 6 weitergegeben.  The actuator 4 is fixed in a cavity 3 of the Pedalgrundkörpers exclusively on the membrane 2. In which the actuator 4 is not supported on the pedal body 1 and the membrane 2 is mounted to vibrate at their ends 5, the energy of the actuator 4 via the membrane 2 largely passed directly to the driver's foot 6.
Wie in Figur 1 gut zu erkennen, hat der Hohlraum 3 ein Übermaß gegenüber dem Aktor 2, so dass die Membran 2 mit dem Aktor 4 im Hohlraum 3 frei schwingungsfähig ist. Der Aktor 4 wird dabei mit Schwingungen einer vorgegebenen Anregungsfrequenz angeregt und sind die Eigenfrequenz der Membran 2 und die Anregungsfrequenz des Aktors 4 so zueinander ausgelegt, dass sich die Anregungsschwingungen überlagern, es also zur Resonanz kommt.  As can be clearly seen in FIG. 1, the cavity 3 has an oversize relative to the actuator 2, so that the membrane 2 with the actuator 4 is freely oscillatable in the cavity 3. The actuator 4 is excited with vibrations of a predetermined excitation frequency and the natural frequency of the diaphragm 2 and the excitation frequency of the actuator 4 are designed to each other so that superimpose the excitation vibrations, so it comes to resonance.
Die Membran 2 gemäß Figur 1 ist dabei auch zum Fahrerfuß hin konvex gewölbt. Der Aktor weist in diesem Ausführungsbeispiel eine drahtlose elektrische Energiezufuhr auf. The membrane 2 according to FIG. 1 is also convexly curved towards the driver's foot. The actuator has a wireless electrical power supply in this embodiment.
Figur 2 skizziert eine alternative Ausgestaltung und skizziert darüber hinaus mit 6 den aufliegenden Fahrerfuß bzw. dessen Schuhsohle. FIG. 2 outlines an alternative embodiment and also outlines with 6 the overlying driver's foot or its shoe sole.
Figur 3 und 4 skizzieren eine weitere alternative Ausgestaltung und Formgebung von Pedalgrundkörper 1 und Membran 2, wobei wiederum der Aktor 4 im Hohlraum 3 entkoppelt vom Pedalgrundkörper 1 freischwingungsfähig angeordnet ist. Durch diese Entkopplung ist es möglich den haptischen Effekt an der Pedalplatte deutlich zu verbessern, die Wahrnehmung durch den Fahrerfuß kann so optimiert werden. Durch einen deutlich höheren haptischen Wirkungsgrad, ist es möglich die verwendeten Aktoren energieeffizienter zu betreiben, oder deren Baugröße zu reduzieren. Dadurch lassen sich auch mögliche Störeinflüsse der Pedalsensorik durch die eingeleitete Vibration minimieren. Figur 3 skizziert dabei eine mögliche flexible elektrische Verbindung vom Aktor 4 über schwingungsfähige Geräte an die Membran 2 und von dort über die Enden 5 in den Pedalgrundkörper 1 . Die hier voranstehend beschriebenen Pedale werden vorzugsweise als Gaspedal für Kraftfahrzeuge für die eingangs bereits beschriebenen Funktionen verwendet. Figures 3 and 4 outline a further alternative embodiment and design of Pedalgrundkörper 1 and 2 membrane, again the actuator 4 in the cavity 3 is decoupled from the pedal body 1 is arranged free-floating. Through this decoupling, it is possible to significantly improve the haptic effect on the pedal plate, the perception by the driver's foot can be optimized. Due to a significantly higher haptic efficiency, it is possible to operate the actuators used more energy efficient, or to reduce their size. As a result, possible interference effects of the pedal sensor can be minimized by the introduced vibration. FIG. 3 outlines a possible flexible electrical connection from the actuator 4 via oscillatory devices to the membrane 2 and from there via the ends 5 into the basic pedal body 1. The pedals described above are preferably used as accelerator pedal for motor vehicles for the functions already described above.
