Description

Die Erfindung betrifft eine Bedieneinrichtung insbesondere für ein Fahrzeug, insbesondere Kraftfahrzeug, mit einem von einem Benutzer betätigbaren Bedienelement, das an einem Trägerelement beweglich gelagert ist, mit zumindest einem ansteuerbaren Aktuator, der dazu ausgebildet ist, das Bedienelement relativ zu dem Trägerelement zu bewegen, und mit einer Federeinrichtung, die zwischen dem Bedienelement und dem Trägerelement angeordnet ist und das Bedienelement an dem Trägerelement beweglich lagert.The invention relates to an operating device, in particular for a vehicle, in particular a motor vehicle, with an operating element which can be actuated by a user and which is movably mounted on a carrier element, with at least one controllable actuator which is designed to move the operating element relative to the carrier element, and with a spring device which is arranged between the operating element and the carrier element and movably supports the operating element on the carrier element.

Stand der TechnikState of the art

Bedieneinrichtungen der eingangs genannten Art sind aus dem Stand der Technik bereits bekannt. Im Fahrzeugbau gibt es bereits zahlreiche Bedieneinrichtungen für jede Art von elektrischen oder mechanischen Geräten, die zunehmend durch Bildschirme mit virtuellen Bedienelementen ersetzt werden. Beispiele dafür sind außerhalb des Fahrzeugbereichs Herdplatten, Kopiergeräte, Mobiltelefone, und im Fahrzeugbereich insbesondere Navigations- und Multimediasysteme. Auch wenn der Benutzer sich mittlerweile an die Bedienung virtueller Bedienelemente gewöhnt hat, fehlt es dem Benutzer häufig an einer haptischen Rückmeldung, wie sie bei realen/mechanischen Schalteinrichtungen für den Benutzer spürbar ist.Control devices of the type mentioned are already known from the prior art. In vehicle construction, there are already numerous operating devices for every type of electrical or mechanical device, which are increasingly being replaced by screens with virtual operating elements. Examples of this are outside of the vehicle area, hotplates, copiers, mobile phones, and in the vehicle area, in particular, navigation and multimedia systems. Even if the user has meanwhile become accustomed to the operation of virtual control elements, the user often lacks haptic feedback, as is felt by the user with real/mechanical switching devices.

Es sind jedoch auch bereits sogenannte haptische Displays bekannt, die beim Berühren einer Bedienoberfläche mithilfe zumindest eines Aktuators eine spezifische Bewegung oder Schwingung ausführen, die beispielsweise von der Stelle der Berührung, einer Bewegungsrichtung und/oder der Berührungskraft abhängig sind. Dadurch wird dem Benutzer eine haptische Rückmeldung bei der Bedienung der Bedieneinrichtung gegeben.However, so-called haptic displays are also already known which, when touching a user interface, use at least one actuator to perform a specific movement or vibration, which depends, for example, on the location of the touch, a direction of movement and/or the force of the touch are dependent. As a result, the user is given haptic feedback when operating the operating device.

Eine derartige Bedieneinrichtung ist beispielsweise auch aus der Druckschrift US 9,436,341 B1 bekannt. Dort ist vorgesehen, dass die Bedienoberfläche von einem Bedienelement gebildet wird, das auf einem Trägerelement durch eine Federeinrichtung beweglich gelagert ist. Ein elektromagnetischer Aktuator ist zwischen Trägerelement und Bedienelement angeordnet, um bei Bedarf das Bedienelement relativ zu dem Trägerelement zu bewegen, um somit die haptische Rückmeldung zu erzeugen.Such an operating device is also known, for example, from the publication US 9,436,341 B1 known. There it is provided that the user interface is formed by an operating element that is movably mounted on a carrier element by a spring device. An electromagnetic actuator is arranged between the carrier element and the operating element in order to move the operating element relative to the carrier element if necessary, in order to thus generate the haptic feedback.

Insbesondere bei großen haptischen Oberflächen kann es durch die Bewegungsrichtung und die erfolgenden Vibrationen zu Luftschall und/oder Körperschall kommen, der sich komfortmindernd auswirken kann.Especially with large haptic surfaces, the direction of movement and the vibrations that occur can lead to airborne noise and/or structure-borne noise, which can reduce comfort.

Aus der Offenlegungsschrift US 2013/285801 A1 ist eine Bedieneinrichtung bekannt, die ein Bedienelement und ein Kompensationselement aufweist, wobei das Bedienelement und das Kompensationselement durch einen Aktuator miteinander verbunden sind. Die Bedieneinrichtung weist außerdem eine einzige Federeinrichtung auf, durch die sowohl das Bedienelement als auch das Kompensationselement beweglich an einem Trägerelement gelagert sind.From the disclosure document U.S. 2013/285801 A1 an operating device is known which has an operating element and a compensation element, the operating element and the compensation element being connected to one another by an actuator. The operating device also has a single spring device, by means of which both the operating element and the compensation element are movably mounted on a carrier element.

Offenbarung der ErfindungDisclosure of Invention

Die erfindungsgemäße Bedieneinrichtung mit den Merkmalen des Anspruchs 1 hat den Vorteil, dass das Entstehen von Körperschall oder Luftschall auf einfache Art und Weise kostengünstig reduziert wird. Erfindungsgemäß ist hierzu vorgesehen, dass ein Kompensationselement an dem Trägerelement beweglich angeordnet ist, und dass der Aktuator mit dem Bedienelement und mit dem Kompensationselement verbunden ist. Das hat zur Folge, dass der Aktuator sowohl mit dem Bedienelement als auch mit dem Kompensationselement zusammenwirkt. Dadurch wirkt sich eine Betätigung des Bedienelements durch den Aktuator auch auf eine Bewegung des Kompensationselements aus. Auch können dadurch Bewegungen von dem Bedienelement auf das Kompensationselement übertragen werden. Hierdurch wird dann erreicht, dass das Kompensationselement in transversaler inverser Bewegungsrichtung zu dem Bedienelement schwingen kann, wodurch Köperschall und/oder Luftschall kompensierbar sind. Vorzugsweise ist das Übertragungsverhalten zwischen der schwingenden Masse des Bedienelements und der des Kompensationselements aufeinander abgestimmt, damit sich die dynamischen Kräfte aufheben (Superpositionsprinzip). Bevorzugt ist das Kompensationselement auf der dem Bedienelement zugewandten Seite des Trägerelements angeordnet. Alternativ ist das Bedienelement auf der von dem Trägerelement abgewandten Seite des Trägerelements angeordnet beziehungsweise gelagert.The operating device according to the invention with the features of claim 1 has the advantage that the occurrence of structure-borne noise or airborne noise is reduced in a simple and cost-effective manner. According to the invention, a compensation element is movably arranged on the carrier element and the actuator is connected to the operating element and to the compensation element. As a result, the actuator interacts both with the control element and with the compensation element. As a result, actuation of the operating element by the actuator also affects movement of the compensation element. This also allows movements to be transferred from the operating element to the compensation element. This then achieves that the compensation element can oscillate in the transverse, inverse direction of movement to the operating element, as a result of which structure-borne noise and/or airborne noise can be compensated for. The transmission behavior between the oscillating mass of the control element and that of the compensation element is preferably matched to one another so that the dynamic forces cancel each other out (superposition principle). The compensation element is preferably arranged on that side of the carrier element which faces the operating element. Alternatively, the operating element is arranged or mounted on the side of the carrier element facing away from the carrier element.

Erfindungsgemäß ist zwischen dem Kompensationselement und dem Trägerelement eine zweite Federeinrichtung angeordnet, die das Kompensationselement an dem Trägerelement lagert. Somit ist eine erste Federeinrichtung zwischen dem Bedienelement und dem Trägerelement und eine zweite Federeinrichtung zwischen dem Trägerelement und dem Kompensationselement vorhanden. Durch die Federeinrichtung entsteht mit dem Bedienelement ein schwingfähiges Bedienmassensystem und mit dem Kompensationselement ein schwingfähiges Kompensationsmassensystem, die insbesondere derart aufeinander abgestimmt sind, durch Anpassen von Masse und Federsteifigkeit, dass die Entstehung von Luftschall und Körperschall minimiert oder vollständig verhindert werden. Optional wird außerdem auch durch die Ausbildung der Federeinrichtungen sowie des Kompensationselements und des Bedienelements ein Dämpfungsmaß und/oder Beschleunigungsmaß eingestellt.According to the invention, a second spring device is arranged between the compensation element and the carrier element, which supports the compensation element on the carrier element. There is thus a first spring device between the operating element and the carrier element and a second spring device between the carrier element and the compensation element. The spring device creates an oscillatable operating mass system with the operating element and an oscillatable compensation mass system with the compensation element, which are in particular matched to one another by adapting the mass and spring stiffness in such a way that the generation of airborne noise and structure-borne noise is minimized or completely prevented. Optionally, a degree of damping and/or degree of acceleration is also set by the design of the spring devices and the compensation element and the operating element.

Bevorzugt sind das Kompensationselement und das Bedienelement nur senkrecht oder nur nahezu senkrecht zu einer Längsmittelebene des Trägerelements verlagerbar. Damit sind Kompensationselement und Bedienelement zumindest im Wesentlichen nur senkrecht aufeinander zu oder voneinander weg bewegbar. Seitwärtsbewegungen werden zumindest weitestgehend ausgeschlossen. Dadurch wird gewährleistet, dass zum einen eine sichere Führung des Bedienelements erfolgt, die dem Benutzer ein wertiges Gefühl vermittelt, und dass zum anderen die Wirkungen der Federeinrichtungen optimal ausgenutzt werden können, um den gewünschten Effekt zu erzielen.The compensation element and the operating element can preferably be displaced only perpendicularly or only almost perpendicularly to a longitudinal center plane of the carrier element. In this way, the compensation element and the operating element can be moved at least essentially only perpendicularly towards one another or away from one another. Sideways movements are at least largely ruled out. This ensures that, on the one hand, the operating element is guided securely, which gives the user a valuable feeling, and, on the other hand, that the effects of the spring devices can be optimally utilized in order to achieve the desired effect.

Gemäß einer bevorzugten Weiterbildung weist das Bedienelement einen berührungsempfindlichen Bildschirm auf. Dazu trägt das Bedienelement ein Display, das von einer durchsichtigen Schutzscheibe überdeckt ist, und das Mittel zur Erkennung/Erfassung der Position zumindest eines Fingers auf der Schutzscheibe umfasst. So kann es sich beispielsweise um ein kapazitives Display handeln. Jedoch sind auch andere Ausführungsformen des berührungsempfindlichen Bildschirms denkbar. Durch die Bewegbarkeit des Bildschirms und den ansteuerbaren Aktuator ist es nunmehr möglich, dem Benutzer ein Schalten eines durch das Display angezeigten virtuellen Schalters haptisch zu vermitteln. Wird beispielweise der Aktuator betätigt, so werden das Bedienelement und das Aktuatorelement aufeinander zu bewegt, um dadurch dem Benutzer einen Schaltvorgang zu simulieren und eine haptische Rückmeldung zu bieten.According to a preferred development, the operating element has a touch-sensitive screen. For this purpose, the operating element carries a display which is covered by a transparent protective pane and which includes means for recognizing/detecting the position of at least one finger on the protective pane. For example, it can be a capacitive display. However, other embodiments of the touch-sensitive screen are also conceivable. Due to the mobility of the screen and the controllable actuator, it is now possible to haptically convey to the user switching a virtual switch shown on the display. If, for example, the actuator is actuated, the control element and the actuator element are moved towards one another in order to thereby simulate a switching process for the user and to offer haptic feedback.

Vorzugsweise ist das Kompensationselement eine Kompensationsmasse. Damit zeichnet sich das Kompensationselement allein durch seine Masse aus, und ist dazu bevorzugt aus einem stabilen, einstückigen, Masseelement gefertigt. Durch eine geschickte Bestimmung der Masse der Kompensationsmasse als Ausgleich zu dem Bedienelement, sind die Vibrationen besonders vorteilhaft kompensierbar.The compensation element is preferably a compensation mass. The compensation element is thus distinguished solely by its mass, and for this purpose it is preferably manufactured from a stable, one-piece mass element. By skilfully determining the mass of the compensation mass as compensation for the operating element, the vibrations can be compensated for in a particularly advantageous manner.

Alternativ ist das Kompensationselement bevorzugt als Beleuchtungseinrichtung für das Bedienelement ausgebildet. Dazu weist das Kompensationselement vorzugsweise ein oder mehrere Leuchtmittel auf, die an einem Substrat oder Träger des Kompensationselements verteilt angeordnet sind, und auf die Rückseite des Bedienelements zu ausgerichtet sind, um das Bedienelement von hinten beziehungsweise aus Richtung des Trägerelements, zu beleuchten. Das Trägerelement ist dazu vorzugsweise abschnittsweise durchsichtig oder mit Durchbrüchen versehen, um zu gewährleisten, dass das von der Beleuchtungseinrichtung erzeugte Licht bis zu dem Bedienelement gelangt. Die Beleuchtungseinrichtung dient insoweit als Kompensationsmasse für das Bedienelement und ist bevorzugt auf die Masse des Bedienelements abgestimmt.Alternatively, the compensation element is preferably designed as a lighting device for the operating element. For this purpose, the compensation element preferably has one or more lamps, which are distributed on a substrate or carrier of the compensation element and are aligned towards the back of the operating element in order to illuminate the operating element from behind or from the direction of the carrier element. For this purpose, the support element is preferably transparent in sections or provided with openings in order to ensure that the light generated by the lighting device reaches the operating element. In this respect, the lighting device serves as a compensation mass for the operating element and is preferably matched to the mass of the operating element.

Insbesondere weisen das Bedienelement und das Kompensationselement, insbesondere die Beleuchtungseinrichtung, zumindest im Wesentlichen das gleiche Gewicht auf. Hierdurch ist eine vorteilhafte Vermeidung der Vibrationen beziehungsweise des Luftschalls und/oder Körperschalls erreicht. Bevorzugt ist der Quotient aus Federsteifigkeit und Masse der schwingfähigen Systeme gleich. Dabei bilden das Kompensationselement und die zweite Federeinrichtung ein schwingfähiges System und das Bedienelement und die erste Federeinrichtung ein weiteres schwingfähiges System.In particular, the operating element and the compensation element, in particular the lighting device, have at least essentially the same weight. In this way, an advantageous avoidance of vibrations or airborne noise and/or structure-borne noise is achieved. The quotient of spring stiffness and mass of the oscillatable systems is preferably the same. The compensation element and the second spring device form an oscillatable system and the operating element and the first spring device form another oscillatable system.

Gemäß einer bevorzugten Weiterbildung der Erfindung sind der Aktuator und die Federeinrichtungen derart ausgebildet, dass das Kompensationselement und das Bedienelement mit demselben Kraftwert gegensinnig beziehungsweise gegenphasig durch den Aktuator ansteuerbar sind. Hierdurch ergibt sich eine besonders vorteilhafte Reduzierung von Körperschall und/oder Luftschall. Darüber hinaus wird durch das Betreiben insbesondere des Bedienelements mit seiner Resonanzfrequenz erreicht, dass die Ansteuerung des Bedienelements durch den Aktuator von dem Benutzer haptisch gut wahrnehmbar ist.According to a preferred development of the invention, the actuator and the spring devices are designed in such a way that the compensation element and the operating element can be controlled by the actuator with the same force value in opposite directions or in phase opposition. This results in a particularly advantageous reduction in structure-borne noise and/or airborne noise. In addition, by operating the operating element in particular at its resonant frequency, the user can easily perceive the activation of the operating element by the actuator.

Weiterhin ist bevorzugt vorgesehen, dass die erste Federeinrichtung und/oder die zweite Federeinrichtung wenigstens ein Federelement, insbesondere mehrere insbesondere gleichmäßig verteilt angeordnete Federelemente aufweisen. Die Federelemente definieren die jeweilige Federsteifigkeit beziehungsweise Elastizität der jeweiligen Federeinrichtung und gewährleisten insbesondere bei einer gleichmäßigen Verteilung, dass Bedienelement und Kompensationselement gleichmäßig mit Federkraft beaufschlagt werden und dadurch eine gleichmäßige Bewegung von Bedienelement und Kompensationselement über deren Flächenerstreckung verteilt gesehen, gewährleistet ist.Furthermore, it is preferably provided that the first spring device and/or the second spring device have at least one spring element, in particular a plurality of spring elements arranged in particular in a uniformly distributed manner. The spring elements define the respective spring stiffness or elasticity of the respective spring device and ensure, in particular with a uniform distribution, that the control element and compensation element are uniformly subjected to spring force and thus a uniform movement of the control element and compensation element distributed over their surface area is ensured.

Bevorzugt ist zumindest ein Federelement ein Elastomer- oder Schaumstofffederelement. Diese Art von Federelement ist kostengünstig und konstruktionstechnisch einfach in die Bedieneinrichtung integrierbar.At least one spring element is preferably an elastomer or foam spring element. This type of spring element is inexpensive and can be easily integrated into the operating device in terms of construction.

Alternativ ist zumindest ein Federelement ein Metallfederelement oder Kunststofffederelement, insbesondere in der Art einer Federzunge. So ist beispielsweise zumindest eines der Federelemente in das Bedienelement oder in das Kompensationselement integriert ausgebildet. So kann beispielsweise das Substrat der Beleuchtungseinrichtung ein oder mehrere Federzungen aufweisen, die als freigeschnittene und herausgebogene Federzungen ausgebildet sind und durch ihre Eigenelastizität die Federwirkung der Federeinrichtung realisieren.Alternatively, at least one spring element is a metal spring element or plastic spring element, in particular in the form of a spring tongue. So is For example, at least one of the spring elements is integrated into the operating element or into the compensation element. For example, the substrate of the lighting device can have one or more spring tongues, which are designed as spring tongues that are cut free and bent out and that implement the spring effect of the spring device through their inherent elasticity.

Der Aktuator ist bevorzugt als elektromagnetischer Aktuator oder als Piezo-Aktuator ausgebildet. Dadurch ist eine kostengünstige und bauraumsparende Realisierung des Aktuators in der Bedieneinrichtung gewährleistet, die außerdem eine schnelle Aktuierung des Bedienelements erlauben. Insbesondere ist der Aktuator mittig zwischen Bedieneinrichtung und Kompensationselement angeordnet, in einer Draufsicht auf das Bedienelement gesehen, sodass die von dem Aktuator hergestellt Aktuatorkraft gleichmäßig auf das Bedienelement und das Kompensationselement wirkt. Optional sind mehrere Aktuatoren zwischen Bedienelement und Kompensationselement angeordnet, wobei die Aktuatoren in diesem Fall bevorzugt gleichmäßig verteilt angeordnet sind, um auch hier eine gleichmäßige Kraftbeaufschlagung von Bedienelement und Kompensationselement zu gewährleisten.The actuator is preferably designed as an electromagnetic actuator or as a piezo actuator. This ensures a cost-effective and space-saving implementation of the actuator in the operating device, which also allows rapid actuation of the operating element. In particular, the actuator is arranged centrally between the operating device and the compensation element, seen in a plan view of the operating element, so that the actuator force produced by the actuator acts evenly on the operating element and the compensation element. Optionally, several actuators are arranged between the operating element and the compensation element, with the actuators preferably being arranged in a uniformly distributed manner in this case in order to ensure a uniform application of force to the operating element and the compensation element here as well.

Weiterhin ist bevorzugt vorgesehen, dass der elektromagnetischer Aktuator ein erstes an dem Bedienelement angeordnetes Aktuatorelement und ein zweites an dem Trägerelement angeordnetes Aktuatorelement aufweist. Damit ist der Aktuator zumindest zweigeteilt ausgebildet, wobei die Aktuatorelemente derart ausgebildet sind, dass sie bei Ansteuerung des Aktuators miteinander wirken, insbesondere anziehend oder abstoßend, um das Bedienelement an das Kompensationselement heranzuziehen oder von diesem abzustoßen.Furthermore, it is preferably provided that the electromagnetic actuator has a first actuator element arranged on the operating element and a second actuator element arranged on the carrier element. The actuator is thus designed in at least two parts, with the actuator elements being designed in such a way that they interact with one another when the actuator is activated, in particular attracting or repelling, in order to pull the operating element towards the compensation element or to repel it.

Insbesondere ist vorgesehen, dass zumindest eines der Aktuatorelemente wenigstens eine bestrombare Spule zum Erzeugen eines magnetischen Feldes aufweist. Durch Bestromen der Spule wird ein magnetisches Feld erzeugt, durch welches ein Aktuatorelement dem anderen Aktuatorelement desselben Aktuators abgestoßen oder an diesen angezogen wird. Insbesondere liegt zwischen den Aktuatorelementen im unbetätigten Zustand der Bedieneinrichtung ein Luftspalt vor, der es erlaubt, dass das Bedienelement aus der unbetätigten Stellung in eine an das Kompensationselement oder das Trägerelement herangezogene Betätigungsstellung durch den Aktuator gezogen werden kann.In particular, it is provided that at least one of the actuator elements has at least one energizable coil for generating a magnetic field. By energizing the coil, a magnetic field is generated, by which an actuator element is repelled or attracted to the other actuator element of the same actuator. In particular, there is an air gap between the actuator elements when the control device is in the non-actuated state, which allows the control element to be moved from the non-actuated position to an actuation position applied to the compensation element or the carrier element can be pulled by the actuator.

Das erfindungsgemäße Fahrzeug mit den Merkmalen des Anspruchs 14 zeichnet sich durch die erfindungsgemäße Bedieneinrichtung aus. Es ergeben sich hierdurch die bereits genannten Vorteile.The vehicle according to the invention with the features of claim 14 is characterized by the operating device according to the invention.

Figur 1 zeigt in einer vereinfachten Schnittdarstellung eine vorteilhafte Bedieneinrichtung 1, die vorteilhafterweise in einem Kraftfahrzeug eingesetzt wird. Jedoch ist auch eine Verwendung der Bedieneinrichtung 1 in anderen Applikationen, wie beispielsweise in einer Küche, an einem Fernseher, an einem Automaten oder dergleichen denkbar. figure 1 shows an advantageous control device 1, which is advantageously used in a motor vehicle, in a simplified sectional view. However, it is also conceivable to use the operating device 1 in other applications, such as in a kitchen, on a television, on a vending machine or the like.

Die Bedieneinrichtung 1 weist ein von einem Benutzer betätigbares Bedienelement 2 auf, das an einem Trägerelement 3 beweglich angeordnet gelagert ist. Dazu ist das Bedienelement 2 durch eine erste Federeinrichtung 4 mit dem Trägerelement 3 verbunden. Die Federeinrichtung 4 weist mehrere Federelemente 5 auf, die gleichmäßig über den Umfang des Bedienelements 2 verteilt angeordnet sind, um eine gleichmäßige Beaufschlagung beziehungsweise Bewegung des Federelements 5 zu gewährleisten. Das Bedienelement 2 weist einen berührungsempfindlichen Bildschirm 6 mit einer Schutzscheibe 7 auf.The operating device 1 has an operating element 2 which can be actuated by a user and which is movably mounted on a carrier element 3 . For this purpose, the operating element 2 is connected to the carrier element 3 by a first spring device 4 . The spring device 4 has a plurality of spring elements 5 which are distributed evenly over the circumference of the operating element 2 in order to ensure that the spring element 5 is acted upon or moved evenly. The operating element 2 has a touch-sensitive screen 6 with a protective screen 7 .

An dem Trägerelement 3 ist weiterhin ein Kompensationselement 8 beweglich gelagert angeordnet, das durch eine zweite Federeinrichtung 9 mit dem Trägerelement 3 verbunden ist. Die zweite Federeinrichtung 9 weist mehrere Federelemente 10 auf, die gleichmäßig über den Umfang des Kompensationselements 8 verteilt angeordnet sind, um eine gleichförmige Bewegung beziehungsweise Beaufschlagung des Kompensationselements 8 zu gewährleisten. Das Kompensationselement 8 ist dabei auf der von dem Bedienelement 2 abgewandten Seite des Trägerelements 3 angeordnet, sodass das Trägerelement 3 zwischen dem Kompensationselement 8 und dem Bedienelement 2 liegt und sich dort insbesondere flächig erstreckt. Gemäß einem alternativen Ausführungsbeispiel, hier nicht dargestellt, ist das Kompensationselement 8 auf der dem Bedienelement 2 zugewandten Seite des Trägerelements 3 angeordnet.Furthermore, a compensation element 8 is movably mounted on the carrier element 3 and is connected to the carrier element 3 by a second spring device 9 . The second spring device 9 has a plurality of spring elements 10 which are distributed evenly over the circumference of the compensation element 8 in order to ensure a uniform movement or loading of the compensation element 8 . The compensation element 8 is arranged on the side facing away from the operating element 2 of the carrier element 3, so that the carrier element 3 between the compensation element 8 and the Operating element 2 is located and extends there in particular flat. According to an alternative exemplary embodiment, not shown here, the compensation element 8 is arranged on the side of the carrier element 3 facing the operating element 2 .

Das Trägerelement 3 ist selbst bevorzugt durch viskoelastische Dämpfungselemente 11 beispielsweise mit einem Armaturenbrett des Kraftfahrzeugs gekoppelt. Die Dämpfungselemente 11 reduzieren zum einen Vibrationen, welche von außen eingeleitet werden, beispielsweise Vibrationen, die durch eine Fahrbahnoberfläche, entlang welcher sich das Kraftfahrzeug bewegt, hervorgerufen werden. Zum anderen werden nicht kompensierte Vibrationen der Bedieneinrichtung selbst reduziert, beispielsweise um die Y-Achse erfolgende Kippbewegungen.The carrier element 3 is itself preferably coupled by viscoelastic damping elements 11 to a dashboard of the motor vehicle, for example. On the one hand, the damping elements 11 reduce vibrations that are introduced from the outside, for example vibrations that are caused by a road surface along which the motor vehicle is moving. On the other hand, uncompensated vibrations of the operating device itself are reduced, for example tilting movements occurring around the Y-axis.

Die Bedieneinrichtung 1 weist weiterhin mehrere Aktuatoren 12 auf, die zwischen dem Bedienelement 2 und dem Kompensationselement 8 angeordnet sind und auch zwischen diesen wirken. Dazu weist jeder der Aktuatoren 12 ein erstes Aktuatorelement 13 auf, das mit dem Bedienelement 2 an dessen dem Trägerelement 3 zugewandten Rückseite verbunden ist, sowie ein zweites Aktuatorelement 14, das mit dem Kompensationselement 8 verbunden ist.The operating device 1 also has a number of actuators 12 which are arranged between the operating element 2 and the compensation element 8 and also act between them. For this purpose, each of the actuators 12 has a first actuator element 13 which is connected to the operating element 2 on its rear side facing the carrier element 3 , and a second actuator element 14 which is connected to the compensation element 8 .

Die Aktuatorelemente 13 und 14 liegen jeweils beabstandet zueinander, sodass zwischen diesen ein Luftspalt 15 verbleibt. Zumindest eines der Aktuatorelemente 13 oder 14 ist mit einer bestrombaren Spule versehen, die, wenn sie bestromt wird, ein magnetisches Feld erzeugt, durch welches das gegenüberliegende Aktuatorelement 14 oder 13 angezogen oder abgestoßen wird. Durch das Ansteuern des jeweiligen Aktuators 12 ist somit das Bedienelement 2 relativ zu dem Trägerelement 3 bewegbar, insbesondere in Richtung des Trägerelements oder von diesem weg. Durch das Ansteuern der Aktuatoren 12 ist somit eine haptische Rückmeldung erzeugbar, die der Benutzer der Bedieneinrichtung 1 insbesondere bei der Bedienung des berührungsempfindlichen Bildschirms 6 verspüren kann.The actuator elements 13 and 14 are each spaced apart from one another, so that an air gap 15 remains between them. At least one of the actuator elements 13 or 14 is provided with an energizable coil which, when energized, generates a magnetic field by which the opposite actuator element 14 or 13 is attracted or repelled. By activating the respective actuator 12, the operating element 2 can be moved relative to the carrier element 3, in particular in the direction of the carrier element or away from it. By controlling the actuators 12, a haptic feedback can thus be generated, which the user of the operating device 1 can feel in particular when operating the touch-sensitive screen 6.

Das Bedienelement 2 und das Kompensationselement 8 sind insbesondere an dem Trägerelement 3 derart geführt, dass sie nur aufeinander zu oder voneinander weg und damit zumindest im Wesentlichen nur senkrecht zur Längsmittelebene des Trägerelements 3 bewegbar sind. Die Federelemente 5, 9 bieten hierzu beispielsweise eine parallele Führungsmechanik.The operating element 2 and the compensation element 8 are guided in particular on the carrier element 3 in such a way that they only face one another or away from each other and thus at least essentially only perpendicular to the longitudinal center plane of the carrier element 3 are movable. For this purpose, the spring elements 5, 9 offer, for example, a parallel guiding mechanism.

Wird der jeweilige Aktuator 12 angesteuert, werden Bedienelement 2 und Kompensationselement 8 transversal beziehungsweise translatorisch aufeinander zu bewegt. Dabei sind bevorzugt die Massen von Bedienelement 2 und Kompensationselement 8 zueinander angepasst, insbesondere derart, dass das Bedienelement 2 und das Kompensationselement 8 zumindest im Wesentlichen die gleiche Masse von beispielsweise 970 g aufweisen. Dadurch erfahren beide Elemente, also das Kompensationselement 8 und das Bedienelement 2, die gleiche Auslenkungsbeschleunigung.If the respective actuator 12 is activated, the operating element 2 and the compensation element 8 are moved towards one another in a transverse or translatory manner. The masses of the operating element 2 and the compensation element 8 are preferably adapted to one another, in particular in such a way that the operating element 2 and the compensation element 8 have at least essentially the same mass of, for example, 970 g. As a result, both elements, ie the compensation element 8 and the operating element 2, experience the same deflection acceleration.

Vorzugsweise sind dazu auch die Federelemente 5, 10 gleich, zumindest mit gleicher Federsteifigkeit k ausgebildet. Eine erste schwingfähige Masse ergibt sich aus dem berührungsempfindlichen Bildschirm 6 mit der Schutzscheibe 7 und der daran angeordneten elektronischen Komponenten, eine zweite schwingfähige Masse ergibt sich aus dem Kompensationselement. Ein günstiger Vibrationsfrequenzbereich der sich transversal aufeinander zu bewegenden Massen liegt bei 10 Hz bis 300 Hz. Dieser Bereich ist von einem Benutzer der Bedieneinrichtung 1 mit dem Finger haptisch gut wahrnehmbar. Durch die Wahl insbesondere der Resonanzfrequenz fR der bewegbaren/schwingbaren Massen im haptisch gut wahrnehmbaren Bereich, lässt sich bei gegebener Masse m der beweglichen Teile durch die mathematische Beziehung f R = 1 2 π k m → k = m ∗ 2 πf R 2

Figure imgb0001
der Wert der benötigten Federsteifigkeit k der Federelemente 5, 10 ermitteln. Es ist wünschenswert, die beweglichen Massen mit der Resonanzfrequenz zu betreiben, da dadurch die Massen die maximale Beschleunigung bei gleichem Energieaufwand im haptisch gut wahrnehmbaren Bereich erfahren. Hier zeigt sich auch, dass abweichende Massen m von Bedienelement 2 und Kompensationselement 8 kein Problem darstellen, da die voneinander abweichenden Massen durch ausgleichende Federkoeffizienten k ausgeglichen werden können, um dennoch beide schwingfähigen Systeme mit der Resonanzfrequenz zu betreiben. Vorzugsweise werden die schwingfähigen Systeme derart ausgebildet, dass die Dämpfungsmaße beider Systeme gleich sind.The spring elements 5, 10 are preferably also designed to be the same, at least with the same spring stiffness k. A first oscillatable mass results from the touch-sensitive screen 6 with the protective pane 7 and the electronic components arranged thereon, and a second oscillatable mass results from the compensation element. A favorable vibration frequency range of the masses moving transversely toward one another is 10 Hz to 300 Hz. By choosing in particular the resonant frequency f R of the moveable/oscillating masses in the range that is easily perceptible to the touch, the mathematical relationship can be used for a given mass m of the moveable parts f R = 1 2 π k m → k = m ∗ 2 πf R 2
Figure imgb0001
 determine the value of the required spring stiffness k of the spring elements 5, 10. It is desirable to operate the moving masses at the resonant frequency, as this means that the masses experience the maximum acceleration with the same expenditure of energy in a range that is easily perceptible to the touch. This also shows that deviating masses m of operating element 2 and compensation element 8 do not pose a problem, since the deviating masses are compensated for by compensating spring coefficients k can be, in order to still operate both oscillatable systems with the resonant frequency. The oscillatable systems are preferably designed in such a way that the damping dimensions of both systems are the same.

Im vorliegenden Ausführungsbeispiel wird eine Resonanzfrequenz der jeweiligen beweglichen Masse von 115 Hz gewählt. Diese Resonanzfrequenz hat sich in vorhergehenden Versuchen als günstig herausgestellt, weil der Resonanzpunkt dadurch mittig im haptisch gut wahrnehmbaren Bereich liegt. Aus Masse und Resonanzfrequenz wird bevorzugt der benötigte Wert der Federsteifigkeit k der Federelemente 5, 10 beziehungsweise der Federeinrichtungen 4, 9 in X-Richtung von vorliegend 506 N/mm bestimmen.In the present exemplary embodiment, a resonant frequency of 115 Hz for the respective movable mass is selected. This resonance frequency has proven to be favorable in previous tests because the resonance point is in the middle of the haptically perceptible range. The required value of the spring stiffness k of the spring elements 5, 10 or of the spring devices 4, 9 in the X-direction of 506 N/mm in the present case is preferably determined from the mass and resonance frequency.

Figur 2 zeigt hierzu den Amplitudengang, sodass Verhältnis aus Beschleunigung zum Wicklungsstrom der Aktuatoren unter Berücksichtigung des Übertragungsverhaltens von dem Bedienelement 2 zu dem Kompensationselement 8. Durch die Abstimmung der Systemparameter der beiden schwingfähigen Systemen beziehungsweise Massen zeigt sich über den gesamten Frequenzbereich ein nahezu kongruenter Amplitudengang. Abweichungen davon sind beispielsweise durch Fertigungstoleranzen zu erklären. Dadurch kompensieren sich zum einen die dynamischen Kräfte der schwingfähigen Systeme beziehungsweise Massen, und zum anderen wird in einem weiteren Frequenzbereich ein günstiges Übertragungsverhalten erzielt. figure 2 shows the amplitude response, so that the ratio of acceleration to the winding current of the actuators, taking into account the transmission behavior from the operating element 2 to the compensation element 8. By matching the system parameters of the two oscillatable systems or masses, an almost congruent amplitude response is shown over the entire frequency range. Deviations from this can be explained, for example, by manufacturing tolerances. On the one hand, this compensates for the dynamic forces of the oscillatable systems or masses, and on the other hand, a favorable transmission behavior is achieved in a wider frequency range.

Die in dem vorliegenden Ausführungsbeispiel verwendete Federsteifigkeit ergibt sich durch die Ausbildung der Federelemente 5, 10 als Polyurethan-Schaumfederelemente, wobei auch Silikone oder andere Ausführungen denkbar sind. Insbesondere sind die Federelemente alternativ als Metallfedern oder Kunststofffedern ausgebildet, die elastisch verformbar sind. Dabei können die Federelemente 5, 10 auch einstückig mit dem Bedienelement 2 oder Kompensationselement 3 ausgebildet sein, um eine hohe Integration der jeweiligen Federeinrichtung 4, 9 in die Bedieneinrichtung 1 zu gewährleisten.The spring stiffness used in the present exemplary embodiment results from the design of the spring elements 5, 10 as polyurethane foam spring elements, with silicone or other designs also being conceivable. In particular, the spring elements are designed alternatively as metal springs or plastic springs that are elastically deformable. The spring elements 5 , 10 can also be designed in one piece with the operating element 2 or the compensation element 3 in order to ensure a high level of integration of the respective spring device 4 , 9 in the operating device 1 .

Bevorzugt sind die Federelemente derart gewählt, dass sie ein nahezu lineares Verhalten von Oberflächengröße zu Federsteifigkeit gewährleisten. Dieses wurde anhand verschiedener Messungen und unterschiedlichen Probemassen sowie unterschiedlichen Schaumfederoberflächen empirisch belegt. Um die Federsteifigkeit mit einem Wert von 506 N/mm zu erreichen, ist damit vorliegend eine Oberfläche von 9000 mm2 nötig. Bei der angegebenen Resonanzfrequenz erfährt das jeweilige System eine Auslenkung von maximal 0,2 mm in x-Richtung.The spring elements are preferably chosen in such a way that they ensure an almost linear behavior of surface area to spring stiffness. This was based on various measurements and different test masses as well as different foam spring surfaces. In order to achieve the spring stiffness with a value of 506 N/mm, a surface of 9000 mm 2 is necessary in the present case. At the specified resonant frequency, the respective system experiences a maximum deflection of 0.2 mm in the x-direction.

Um das Gewichtsverhältnis der schwingenden Masse m2 des Bedienelements 2 zu der schwingenden Masse m8 des Kompensationselements 8 zu beeinflussen, wird in Abhängigkeit von den Beschleunigungen a 2 des Bedienelements 2 und a 8 des Kompensationselements 8 folgende mathematische Beziehung bevorzugt berücksichtigt: m 8 ∗ a → 8 = m 2 ∗ a → 2

Figure imgb0002
Dadurch ist es möglich, durch Erhöhung der Beschleunigung a 2 oder a 8 des Massesystems des Bedienelements 2 die Masse m8 des Kompensationselements 8 zu reduzieren. Dadurch würde sich ein geringeres Gewicht des Gesamtsystems ergeben. Alternativ sind Kompensationsmasse m8 und die Masse m2 des Bedienelements 2 gleich groß gewählt.In order to influence the weight ratio of the oscillating mass m 2 of the control element 2 to the oscillating mass m 8 of the compensation element 8, depending on the accelerations a 2 of the control element 2 and a 8 of the compensation element 8 preferably takes into account the following mathematical relationship: m 8th ∗ a → 8th = m 2 ∗ a → 2
Figure imgb0002
 This makes it possible by increasing the acceleration a 2 or a 8 of the mass system of the control element 2 to reduce the mass m 8 of the compensation element 8 . This would result in a lower weight of the overall system. Alternatively, the compensation mass m 8 and the mass m 2 of the operating element 2 are selected to be the same.

Besonders bevorzugt ist das Kompensationselement 8 als Beleuchtungseinrichtung 16 ausgebildet, die eine Vielzahl von Leuchtmitteln 17 aufweist, wie in Figur 1 beispielhaft gezeigt. Die Leuchtmittel 17 sind dabei auf der dem Trägerelement 3 beziehungsweise dem Bedienelement 2 zugewandten Oberseite eines Substrats 18 des Kompensationselements 8 insbesondere gleichmäßig verteilt angeordnet, sodass sie das Bedienelement 2 von seiner Rückseite her beleuchten.Compensation element 8 is particularly preferably designed as an illumination device 16, which has a large number of illuminants 17, as shown in FIG figure 1 shown as an example. The light sources 17 are arranged on the top side of a substrate 18 of the compensation element 8 facing the carrier element 3 or the operating element 2, in particular evenly distributed, so that they illuminate the operating element 2 from its rear side.

Figur 3 zeigt dazu in einer vereinfachten Explosionsdarstellung die Bedieneinrichtung 1, bei welcher das Trägerelement 3 zwischen dem Bedienelement 2 und dem Kompensationselement 8 angeordnet ist. Das Trägerelement 3 ist rahmenförmig ausgebildet, sodass es eine Aussparung 19 aufweist, durch welche das von den Leuchtmitteln 17 erzeugte Licht durch das Trägerelement 3 hindurchdringen kann, um das Bedienelement 2, insbesondere den Bildschirm 6 von hinten zu beleuchten beziehungsweise anzuleuchten, sodass dieser für den Benutzer besser ablesbar ist. Mehrere Aktuatoren 12 sind dabei ebenfalls um die Aussparung herum gleichmäßig verteilt angeordnet. Die Federelemente 5, 10 sind aus Übersichtlichkeitsgründen in Figur 3 nicht gezeigt. figure 3 shows the operating device 1 in a simplified exploded view, in which the carrier element 3 is arranged between the operating element 2 and the compensation element 8 . The carrier element 3 is designed in the shape of a frame, so that it has a recess 19 through which the light generated by the lamps 17 can penetrate through the carrier element 3 to the operating element 2, in particular to illuminate or illuminate the screen 6 from behind, so that it is easier to read for the user. A plurality of actuators 12 are also arranged in a uniformly distributed manner around the cutout. For reasons of clarity, the spring elements 5, 10 are figure 3 Not shown.
