BESCHREIBUNG: Die Erfindung betrifft eine Bedienvorrichtung für ein Fahrzeug, insbesondere einen Kraftwagen, gemäß dem Oberbegriff von Patentanspruch 1. DESCRIPTION The invention relates to an operating device for a vehicle, in particular a motor vehicle, according to the preamble of patent claim 1.
Eine solche Bedienvorrichtung für ein Fahrzeug, insbesondere einen Kraftwagen wie beispielsweise einen Personenkraftwagen, ist beispielsweise be- reits der DE 10 2013 006 414 A1 als bekannt zu entnehmen. Die Bedienvorrichtung umfasst dabei wenigstens ein Trägerelement sowie wenigstens ein Bedienelement, welches bewegbar an dem Trägerelement gehalten ist. Mittels des Bedienelements ist von einer Person, beispielsweise dem Fahrer des Kraftwagens, durch Betätigen des Bedienelements wenigstens eine Funktion des Fahrzeugs bewirkbar. Such an operating device for a vehicle, in particular a motor vehicle such as a passenger car, for example, is already known from DE 10 2013 006 414 A1 as known. The operating device comprises at least one support element and at least one operating element, which is held movably on the support element. By means of the control element, at least one function of the vehicle can be effected by a person, for example the driver of the motor vehicle, by actuating the operating element.
Die Bedienvorrichtung umfasst darüber hinaus wenigstens einen Aktor, mittels welchem zur Erzeugung einer haptischen Rückmeldung an die Person infolge der Betätigung des Bedienelements das Bedienelement in wenigs- tens eine Bewegungsrichtung relativ zu dem Trägerelement bewegbar ist. The operating device further comprises at least one actuator, by means of which the operating element can be moved in at least one direction of movement relative to the carrier element in order to generate a haptic feedback to the person as a result of the actuation of the operating element.
Zum Bewirken der Funktion über das Bedienelement berührt die Person das Bedienelement. Ferner wird das Bedienelement von der Person mit einer Kraft beaufschlagt, um die Funktion schließlich zu bewirken. Infolge dieser Kraftbeaufschlagung, das heißt infolge des Bewirkens der Funktion beziehungsweise des Betätigens des Bedienelements wird das Bedienelement mittels des Aktors in die Bewegungsrichtung relativ zum Trägerelement bewegt. Die das Bedienelement berührende Person kann diese Bewegung des Bedienelements haptisch wahrnehmen, das heißt fühlen. Hierdurch wird der Person haptisch mitgeteilt, dass eine Betätigung des Bedienelements erfolgt ist beziehungsweise dass die Betätigung erfolgreich war und demzufolge die Funktion bewirkt wurde. Die DE 10 2010 007 486 A1 offenbart eine Bedienvorrichtung mit einem Bedienelement mit haptischer Rückmeldung, wobei das Bedienelement von einem Bediener mittels eines Eingabeorgans betätigbar ist. Aus der DE 10 2008 040 755 B4 ist eine berührungsempfindliche Anzeigevorrichtung für Kraftfahrzeuge bekannt, wobei ein vom Bediener bewegbares mechanisches Bedienelement und ein Haltemagnet vorgesehen sind. To effect the function via the operating element, the person touches the operating element. Furthermore, the operating element is acted upon by the person with the force to finally effect the function. As a result of this application of force, that is, as a result of effecting the function or the actuation of the operating element, the operating element is moved by means of the actuator in the direction of movement relative to the carrier element. The person touching the operating element can perceive, that is feel, this movement of the operating element. As a result, the person is haptically informed that an actuation of the operating element has taken place or that the actuation was successful and consequently the function has been effected. DE 10 2010 007 486 A1 discloses an operating device with an operating element with haptic feedback, wherein the operating element can be actuated by an operator by means of an input member. From DE 10 2008 040 755 B4 a touch-sensitive display device for motor vehicles is known, wherein an operator movable mechanical operating element and a holding magnet are provided.
Die DE 10 2005 014 939 A1 offenbart ein Bedienelement zur Steuerung ei- nes Fahrzeugrechners und der Funktionen von daran angeschlossenen Systemen oder Baugruppen eines Fahrzeugs.

Object of the present invention is to develop an operating device of the type mentioned in such a way that an improved operation of the operating device can be realized. This object is achieved by an operating device having the features of patent claim 1. Advantageous embodiments with expedient developments of the invention are specified in the remaining claims.
Die erfindungsgemäße Bedienvorrichtung für ein Fahrzeug, insbesondere einen Kraftwagen wie beispielsweise einen Personenkraftwagen, umfasst wenigstens ein Trägerelement sowie wenigstens ein Bedienelement, welches an dem Trägerelement relativ zu diesem bewegbar gehalten ist. Mittels des Bedienelements ist von einer Person, beispielsweise dem Fahrer des Kraftwagens, durch Betätigen des Bedienelements wenigstens eine Funktion des Fahrzeugs bewirkbar. Die Bedienvorrichtung umfasst darüber hinaus wenigstens einen Aktor, mittels welchem zur Erzeugung einer haptischen Rückmeldung an die Person infolge der Betätigung des Bedienelements das Bedienelement in wenigstens eine Bewegungsrichtung relativ zu dem Trägerelement bewegbar ist. The operating device according to the invention for a vehicle, in particular a motor vehicle such as a passenger car, comprises at least one carrier element and at least one operating element, which is held on the carrier element relative to this movable. By means of the control element, at least one function of the vehicle can be effected by a person, for example the driver of the motor vehicle, by actuating the operating element. The operating device further comprises at least one actuator, by means of which, in order to generate a haptic feedback to the person as a result of the actuation of the operating element, the operating element is movable in at least one direction of movement relative to the carrier element.
Um nun eine verbesserte Bedienung der Bedienvorrichtung auf einfache Weise zu realisieren, ist erfindungsgemäß wenigstens ein Fixierelement vorgesehen, welches zwischen wenigstens einer das Bedienelement formschlüssig gegen eine Bewegung entlang der Bewegungsrichtung relativ zu dem Trägerelement sichernden Fixierstellung und wenigstens einer das Bedienelement freigebenden Freigabestellung bewegbar ist. Mit anderen Worten ist das Bedienelement in der Fixierstellung mittels des Fixierelements formschlüssig gegen eine Bewegung entlang der Bewegungsrichtung relativ zum Trägerelement gesichert. Wird das Bedienelement beispielsweise nicht von der Person mit einer Kraft beaufschlagt, das heißt wird das Bedienelement durch die Person nicht betätigt beziehungsweise bedient, so befindet sich das Bedienelement beispielsweise in einer Ruhestellung. Betätigt die Person das Bedienelement, so wird infolge dieser Betätigung das Bedien- element mittels des Aktors beispielsweise aus der Ruhestellung in wenigstens eine Bewegungsstellung entlang der Bewegungsrichtung bewegt, um hierdurch die haptische Rückmeldung an die Person zu erzeugen. In order to realize an improved operation of the operating device in a simple manner, according to the invention at least one fixing element is provided, which between at least one of the control element positively against movement along the direction of movement relative to the fixing element securing the carrier element and at least one release position releasing the operating element is movable. In other words, the operating element in the fixing position by means of the fixing element is positively secured against movement along the direction of movement relative to the carrier element. If, for example, the operating element is not acted upon by the person with a force, that is to say the operating element is not actuated or operated by the person, then the operating element is in a rest position, for example. If the person actuates the operating element, as a result of this actuation the operating element is moved by means of the actuator, for example, from the rest position into at least one movement position along the direction of movement, in order thereby to generate the haptic feedback to the person.
Befindet sich das Bedienelement beispielsweise in seiner Ruhestellung und ist das Fahrzeug beispielsweise deaktiviert, sodass die Funktion durch Betätigen des Bedienelements nicht bewirkt werden kann, so könnte das Bedienelement durch die Person jedoch entlang der Bewegungsrichtung bewegt werden, da eine solche Bewegung nicht verhindert wäre. Da sich in diesem Fall jedoch erfindungsgemäß das Fixierelement in seiner Fixierstellung be- findet, kann die Person das Bedienelement nicht unerwünschterweise aus der Ruhestellung entlang der Bewegungsrichtung bewegen, da das Bedienelement mittels des Fixierelements gegen eine solche Bewegung gesichert ist. Dies bedeutet, dass es sich bei dem Fixierelement um ein mechanisches Fixierelement handelt, welches in seiner Fixierstellung zumindest mittelbar formschlüssig mit dem Bedienelement zusammenwirkt, wodurch das Bedienelement mechanisch gegen Bewegungen entlang der Bewegungsrichtung gesichert ist und somit nicht von der Person unerwünschterweise entlang der Bewegungsrichtung relativ zum Trägerelement bewegt werden kann. For example, if the operating element is in its rest position and the vehicle is deactivated, for example, so that the function can not be effected by actuating the operating element, then the operating element could be moved by the person along the direction of movement, since such a movement would not be prevented. However, since in this case according to the invention the fixing element is in its fixing position, the person can not move the operating element undesirably out of the rest position along the direction of movement, since the operating element is secured against such movement by means of the fixing element. This means that the fixing element is a mechanical fixing element which, in its fixing position, cooperates with the operating element in a form-fitting manner, whereby the operating element is mechanically secured against movements along the direction of movement and thus not undesired by the person along the direction of movement relative to Carrier element can be moved.
Ist das Fahrzeug jedoch beispielsweise aktiviert und wird das Bedienelement durch die Person betätigt, so wird das mechanische Fixierelement, insbesondere infolge der Betätigung des Bedienelements, in seine Freigabestellung bewegt, in welcher das mechanische Fixierelement nicht mehr form- schlüssig mit dem Bedienelement zusammenwirkt. Somit gibt das Fixierelement das Bedienelement frei, sodass das Bedienelement mittels des Aktors gezielt entlang der Bewegungsrichtung relativ zum Trägerelement bewegt werden kann. Mittels des Fixierelements ist es somit möglich, das Bedienelement gegen unerwünschte Bewegungen entlang der Bewegungsrichtung relativ zum Trägerelement zu sichern, jedoch erwünschte und beispielsweise mittels des Aktors erzeugte Bewegungen des Bedienelements relativ zum Trägerelement gezielt freizugeben, sodass auf besonders einfache Weise eine besonders vorteilhafte Bedienung der Bedienvorrichtung darstellbar ist. Insbesondere ist es möglich, einen besonders hochwertigen Eindruck der Bedienvorrichtung sowie eine präzise Bedienung dieser zu realisieren, da unerwünschte Bewegungen des Bedienelements relativ zum Trägerelement vermieden, jedoch erwünschte Bewegungen des Bedienelements relativ zum Trägerelement gezielt zugelassen werden können. However, if the vehicle is activated, for example, and the operating element is actuated by the person, the mechanical fixing element, in particular as a result of the actuation of the operating element, is moved into its release position, in which the mechanical fixing element no longer cooperates in a form-fitting manner with the operating element. Thus, the fixing element releases the operating element so that the operating element can be moved in a targeted manner along the direction of movement relative to the carrier element by means of the actuator. By means of the fixing element, it is thus possible, the control element against unwanted movements along the direction of movement To secure relative to the carrier element, however, release targeted and generated for example by means of the actuator movements of the operating element relative to the support element targeted, so that in a particularly simple manner, a particularly advantageous operation of the operating device can be displayed. In particular, it is possible to realize a particularly high-quality impression of the operating device as well as a precise operation thereof, since undesired movements of the operating element relative to the carrier element are avoided, but desired movements of the operating element relative to the carrier element can be specifically authorized.
Das Fixierelement wird als mechanisches Rastelement verwendet, mittels welchem infolge des formschlüssigen Zusammenwirkens zwischen dem Rastelement und dem Bedienelement unerwünschte Bewegungen des Bedienelements sicher vermieden werden können. The fixing element is used as a mechanical latching element, by means of which undesired movements of the operating element can be reliably avoided as a result of the positive cooperation between the latching element and the operating element.
In vorteilhafter Ausgestaltung der Erfindung ist ein Aktor vorgesehen, mittels welchem das Fixierelement zwischen der Fixierstellung und der Freigabestellung bewegbar ist. Insbesondere ist der Aktor dazu ausgebildet, das Fixierelement aus der Fixierstellung in die Freigabestellung zu bewegen. Hier- durch ist eine besonders bedarfsgerechte, gezielte und einfache Bewegung des Fixierelements darstellbar. In an advantageous embodiment of the invention, an actuator is provided, by means of which the fixing element between the fixing position and the release position is movable. In particular, the actuator is designed to move the fixing element from the fixing position into the release position. As a result, a particularly needs-based, targeted and simple movement of the fixing element can be displayed.
Als besonders vorteilhaft hat es sich gezeigt, wenn der Aktor zum Bewegen des Bedienelements ein erster Aktor und der Aktor zum Bewegen des Fixier- elements ein vom ersten Aktor unterschiedlicher, zusätzlich dazu vorgesehener zweiter Aktor ist. Hierdurch sind Bewegungen des Bedienelements sowie Bewegungen des Fixierelements besonders gezielt und bedarfsgerecht durchführbar, sodass eine besonders vorteilhafte Bedienung der Bedienvorrichtung realisiert werden kann. It has proven to be particularly advantageous if the actuator for moving the operating element is a first actuator and the actuator for moving the fixing element is a second actuator which is different from the first actuator and additionally provided. As a result, movements of the operating element and movements of the fixing are particularly targeted and needs-based feasible, so that a particularly advantageous operation of the operating device can be realized.
Als besonders vorteilhaft hat es sich gezeigt, wenn der Aktor zum Bewegen des Fixierelements ein elektrischer Aktor, insbesondere ein elektromagnetischer Aktor, ist. Dadurch ist es möglich, das Fixierelement besonders schnell, das heißt in besonders kurzer Zeit aus der Fixierstellung in die Frei- gabestellung zu bewegen, um dadurch beispielsweise besonders schnell auf eine gezielte Betätigung des Bedienelements zu reagieren und somit das Bedienelement gezielt mittels des Aktors relativ zum Trägerelement zu bewegen. Bei einer weiteren Ausführungsform der Erfindung ist dem Fixierelement wenigstens ein zumindest in der Freigabestellung gespanntes Federelement zugeordnet, mittels welchem das Fixierelement unter zumindest teilweisem Entspannen des Federelements aus der Freigabestellung in die Fixierstel- lung bewegbar und in der Fixierstellung zu halten ist. Dadurch können Bewegungen des Fixierelements zwischen der Freigabestellung und der Fixierstellung auf besonders einfache, platzsparende und energieeffiziente Weise realisiert werden. Um unerwünschte Bewegungen des Bedienelements relativ zum Trägerelement besonders sicher zu vermeiden, ist es bei einer weiteren Ausführungsform der Erfindung vorgesehen, dass das Fixierelement in der Fixierstellung in eine relativ zum Bedienelement unbewegbare, das heißt fest am Bedienelement vorgesehene Ausnehmung eingreift. Insbesondere ist es so möglich, dass das Fixierelement zumindest nahezu spielfrei mit dem Bedienelement formschlüssig zusammenwirkt, sodass Bewegungen des Bedienelements entlang der Bewegungsrichtung sicher vermieden werden können. Hierdurch lässt sich ein besonders hochwertiger Eindruck der Bedienvorrichtung realisieren. It has proven to be particularly advantageous if the actuator for moving the fixing element is an electrical actuator, in particular an electromagnetic actuator. As a result, it is possible to move the fixing element out of the fixing position into the release position in a particularly short time, in order, for example, to react particularly quickly to a specific actuation of the operating element and thus to control the operating element specifically by means of the actuator relative to the control element Carrier element to move. In a further embodiment of the invention, at least one tensioned at least in the release position spring element is associated with the fixing, by means of which the fixing is at least partially relaxing the spring element from the release position into the fixing position to keep movable and in the fixing position. As a result, movements of the fixing between the release position and the fixing position can be realized in a particularly simple, space-saving and energy-efficient manner. In order to avoid unwanted movements of the operating element relative to the carrier element particularly secure, it is provided in a further embodiment of the invention that the fixing engages in the fixing position in a fixed relative to the control element, that is fixedly provided on the operating element recess. In particular, it is possible that the fixing element at least almost without play cooperates with the operating element form-fitting, so that movements of the operating element along the direction of movement can be safely avoided. This makes it possible to realize a particularly high-quality impression of the operating device.
Zur Erfindung gehört auch ein Fahrzeug, insbesondere ein Kraftwagen wie beispielsweise ein Personenkraftwagen, mit wenigstens einer erfindungsgemäßen Bedienvorrichtung. Vorteilhafte Ausgestaltungen der erfindungsgemäßen Bedienvorrichtung sind als vorteilhafte Ausgestaltungen des erfin- dungsgemäßen Fahrzeugs anzusehen und umgekehrt. The invention also includes a vehicle, in particular a motor vehicle such as a passenger car, with at least one operating device according to the invention. Advantageous embodiments of the operating device according to the invention are to be regarded as advantageous embodiments of the inventive vehicle and vice versa.
Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines bevorzugten Ausführungsbeispiels sowie anhand der Zeichnung. Die vorstehend in der Beschreibung genannten Merkmale und Merkmalskombinationen sowie die nachfolgend in der Figurenbeschreibung genannten und/oder in der einzigen Figur alleine gezeigten Merkmale und Merkmalskombinationen sind nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen oder in Alleinstellung verwendbar, ohne den Rahmen der Erfindung zu verlassen. Further advantages, features and details of the invention will become apparent from the following description of a preferred embodiment and from the drawing. The features and feature combinations mentioned above in the description as well as the features and feature combinations mentioned below in the figure description and / or alone in the single figure can be used not only in the respectively indicated combination but also in other combinations or alone, without the frame to leave the invention.
Die Zeichnung zeigt in der einzigen Figur (Fig.) eine schematische Vorderansicht einer Bedienvorrichtung für ein Fahrzeug, mit wenigstens einem Bedienelement und mit wenigstens einem Aktor, mittels welchem zur Erzeugung einer haptischen Rückmeldung an eine Person das Bedienelement in wenigstens eine Bewegungsrichtung relativ zu einem Trägerelement der Bedienvorrichtung bewegbar ist, wobei wenigstens ein mechanisches Fixierelement vorgesehen ist, mittels welchem das Bedienelement formschlüssig in einer Ruhestellung fixierbar ist. The drawing shows in the single figure (Fig.) A schematic front view of an operating device for a vehicle, with at least one control element and at least one actuator, by means of which to generate a haptic feedback to a person, the control in at least one movement direction relative to a carrier element of the operating device is movable, wherein at least one mechanical fixing element is provided, by means of which the operating element is positively fixed in a rest position.
Die Fig. zeigt in einer schematischen Vorderansicht eine im Ganzen mit 10 bezeichnete Bedienvorrichtung für ein Fahrzeug, insbesondere einen Kraftwagen wie beispielsweise einen Personenkraftwagen. Die Bedienvorrichtung 10 umfasst ein Trägerelement 12, welches beispielsweise ein Gehäuseteil der Bedienvorrichtung 10 ist. Ferner umfasst die Bedienvorrichtung 10 wenigstens ein Bedienelement 14, welches auch als Bedienteil bezeichnet wird. Aus der Fig. ist erkennbar, dass das Bedienelement 14 vorliegend als Bedienleiste ausgebildet ist und demzufolge eine Längserstreckungsrichtung aufweist. Die Bedienleiste weist eine Mehrzahl von Betätigungsbereichen 16 auf, über welche durch eine Person wie beispielsweise der Fahrer des Kraftwagens jeweilige Funktionen des Fahrzeugs (Kraftwagens) bewirkbar sind. Mit anderen Worten sind die jeweiligen Funktionen des Fahrzeugs von der Person durch Betätigen des Bedienelements 14 bewirkbar. Hierzu berührt die Person beispielsweise mit einem Finger 18 ihrer Hand 20 einen der Betä- tigungsbereiche 16 und übt auf das Bedienelement 14 eine Kraft aus. Diese durch die Person bewirkte und auf das Bedienelement 14 wirkende Kraftbeaufschlagung wird beispielsweise mittels wenigstens eines Kraftsensors er- fasst. Übersteigt die Kraftbeaufschlagung einen vorgebbaren Schwellenwert, so wird diejenige der Funktionen ausgeführt, die demjenigen der Betäti- gungsbereiche 16 zugeordnet ist, den die Person mit ihrem Finger 18 berührt. The FIGURE shows a schematic front view of a generally designated 10 operating device for a vehicle, in particular a motor vehicle such as a passenger car. The operating device 10 comprises a carrier element 12 which, for example, is a housing part of the operating device 10. Furthermore, the operating device 10 comprises at least one operating element 14, which is also referred to as a control unit. From the Fig. It can be seen that the operating element 14 in the present case is designed as a control bar and therefore has a longitudinal direction. The control bar has a plurality of operating areas 16, via which by a person such as the driver of the motor vehicle respective functions of the vehicle (motor vehicle) are effected. In other words, the respective functions of the vehicle can be effected by the person by actuating the operating element 14. For this purpose, for example, the person touches one of the actuation areas 16 with a finger 18 of his hand 20 and exerts a force on the operating element 14. This force applied by the person and acting on the operating element 14 is detected, for example, by means of at least one force sensor. If the application of force exceeds a predefinable threshold value, that of the functions assigned to that of the actuating regions 16 which the person touches with his finger 18 is carried out.
Aus der Fig. ist ferner erkennbar, dass die Bedienvorrichtung 10 Federelemente 22 umfasst, welche vorliegend als Blattfedern aus einem metallischen Werkstoff gebildet sind. Mit anderen Worten sind die Federelemente 22 vorliegend als metallische Blattfedern beziehungsweise Metallfedern ausgebildet. Das Bedienelement 14 ist dabei unter Vermittlung der Federelemente 22 an dem Trägerelement 12 relativ zu diesem bewegbar gehalten. Dabei ist das Bedienelement 14 in eine Bewegungsrichtung relativ zu dem Trägerele- ment 12 bewegbar, wobei die Bewegungsrichtung durch einen Doppelpfeil 24 in der Fig. veranschaulicht ist. Wird das Bedienelement 14 in die Bewegungsrichtung (Doppelpfeil 24) relativ zu dem Trägerelement 12 bewegt, so werden dadurch die Federelemente 22 elastisch verformt. Die Fig. zeigt eine Ruhestellung oder Ruhelage des Bedienelements 14. Das Bedienelement 14 ist entlang der Bewegungsrichtung aus dieser Ruhestellung relativ zu dem Trägerelement 12 bewegbar und dabei beispielsweise in eine Vielzahl von sogenannten Bewegungsstellungen bewegbar. Wird das Bedienelement 14 relativ zum Trägerelement 12 aus der Ruhestellung in die jeweilige Bewegungsstellung bewegt, so werden dadurch die Federelemente 22 gespannt. Mit anderen Worten sind die Federelemente 22 in der jeweiligen Bewegungsstellung gegenüber der Ruhestellung gespannt, wodurch das Bedienelement 14 mittels der Federelemente 22 mit einer Federkraft beauf- schlagt wird. Mittels dieser Federkraft wird das Bedienelement 14 unter zumindest teilweisem Entspannen der Federelemente 22 aus der jeweiligen Bewegungsstellung in die Ruhestellung zurückbewegt. From the Fig. It is further seen that the operating device 10 comprises spring elements 22, which are presently formed as leaf springs made of a metallic material. In other words, the spring elements 22 are embodied here as metallic leaf springs or metal springs. The operating element 14 is held by the intermediary of the spring elements 22 on the carrier element 12 relative to this movable. In this case, the operating element 14 is movable in a direction of movement relative to the carrier element 12, the direction of movement being illustrated by a double arrow 24 in the FIGURE. If the operating element 14 is moved in the direction of movement (double arrow 24) relative to the carrier element 12, the spring elements 22 are thereby elastically deformed. The Fig. Shows a rest position or rest position of the operating element 14. The operating element 14 is movable along the direction of movement from this rest position relative to the support member 12 and thereby movable, for example, in a plurality of so-called movement positions. If the operating element 14 is moved relative to the carrier element 12 from the rest position into the respective movement position, the spring elements 22 are thereby tensioned. In other words, the spring elements 22 are stretched in the respective movement position relative to the rest position, whereby the operating element 14 is acted upon by the spring elements 22 with a spring force. By means of this spring force, the operating element 14 is moved back under at least partial relaxation of the spring elements 22 from the respective movement position into the rest position.
Die Bedienvorrichtung 10 umfasst darüber hinaus einen ersten Aktor 26, welcher vorliegend als elektrischer Aktor und insbesondere elektromagnetischer Aktor ausgebildet ist. Der erste Aktor 26 umfasst eine mit elektrischem Strom versorgbare Spule 28, einen Zylinder 30 und eine Kolbenstange 32, welche zumindest teilweise im Zylinder 30 aufgenommen und relativ zum Zylinder 30 translatorisch bewegbar ist. Mit der Kolbenstange 32 ist ein Kol- ben 34 verbunden. Die Kolbenstange 32 und der Kolben 34 bilden einen Anker, welcher mittels der Spule 28 elektromagnetisch bewegbar ist. Zum Bewegen des Ankers wird die Spule 28 bestromt, das heißt mit elektrischem Strom versorgt, sodass der elektrische Strom durch die Spule 28 fließt. An dem Bedienelement 14 ist ein Betätigungselement 36 vorgesehen, mit welchem der erste Aktor 26, insbesondere der Anker, zusammenwirken kann. Wird die Spule 28 bestromt, so wird der Anker in Stützanlage mit dem Betätigungselement 36 bewegt. Durch das Bestromen der Spule 28 wirken der Anker und das Betätigungselement 36 derart zusammen, dass das Be- dienelement 14 mittels des ersten Aktors 26 aus der Ruhestellung relativ zum Trägerelement 12 in eine der Bewegungsstellungen bewegt wird. Wie bereits zuvor geschildert, sind die Federelemente 22 in dieser einen Bewegungsstellung gespannt. Dann wird das Bestromen der Spule 28 beendet, sodass sich die Federelemente 22 zumindest teilweise entspannen können, wodurch das Bedienelement 14 mittels der Federelemente 22 aus der einen Bewegungsstellung zurück in Richtung der Ruhestellung beziehungsweise in die Ruhestellung bewegt wird. Dabei kann das Bedienelement 14 auf die geschilderte Weise mehrmals zwischen zumindest einer der Bewegungsstellungen und der Ruhestellung bewegt werden. Diese mittels des ersten Aktors 26 bewirkte Bewegung des Bedienelements 14 relativ zum Trägerelement 12 wird infolge einer durch die Person bewirkten Betätigung des Bedienelements 14 durchgeführt, da durch die mittels des ersten Aktors 26 bewirkte Bewegung des Bedienelements 14 relativ zum Trägerelement 12 eine haptische Rückmeldung an die Person infolge der Betätigung des Bedienelements 14 erzeugt wird. Die mittels des ersten Aktors 26 entlang der Bewegungsrichtung bewirkte Bewegung des Bedienelements 14 relativ zum Trägerelement 12 kann von der das Bedienelement 14 berührenden Person gefühlt, das heißt haptisch wahrgenommen werden, wobei die Person diese Bewegung insbesondere als Nachgeben des Bedienelements 14 wahrnimmt. Durch diese haptische Rückmeldung kann der Person beispielsweise vermittelt werden, dass die gewünschte Funktion bewirkt wurde und demzufolge die von der Person gewünschte Betätigung der Bedienvorrichtung 10 erfolgreich war. The operating device 10 also includes a first actuator 26, which is presently designed as an electrical actuator and in particular electromagnetic actuator. The first actuator 26 comprises a coil 28, which can be supplied with electric current, a cylinder 30 and a piston rod 32, which is accommodated at least partially in the cylinder 30 and is translationally movable relative to the cylinder 30. A piston 34 is connected to the piston rod 32. The piston rod 32 and the piston 34 form an armature which is electromagnetically movable by means of the coil 28. To move the armature, the coil 28 is energized, that is supplied with electric current, so that the electric current flows through the coil 28. On the operating element 14, an actuating element 36 is provided, with which the first actuator 26, in particular the armature, can cooperate. If the coil 28 is energized, the armature is moved in support system with the actuating element 36. By energizing the coil 28, the armature and the actuating element 36 cooperate in such a way that the operating element 14 is moved by means of the first actuator 26 from the rest position relative to the carrier element 12 in one of the movement positions. As already described above, the spring elements 22 are tensioned in this one movement position. Then the energizing of the coil 28 is stopped, so that the spring elements 22 can relax at least partially, whereby the operating element 14 is moved by means of the spring elements 22 from the one movement position back toward the rest position or in the rest position. In this case, the operating element 14 can be moved in the manner described several times between at least one of the movement positions and the rest position. This caused by the first actuator 26 movement of the control element 14 relative to the carrier element 12 is carried out as a result of a person effected by the operation of the control element 14, as caused by the means of the first actuator 26 caused movement of the control element 14 relative to the support member 12 is a haptic feedback to the Person is generated as a result of the operation of the control element 14. The movement of the operating element 14 relative to the carrier element 12 effected by means of the first actuator 26 along the direction of movement can be felt by the person touching the operating element 14, ie can be perceived haptically, the person perceiving this movement in particular as yielding of the operating element 14. By means of this haptic feedback, the person can be conveyed, for example, that the desired function has been effected and consequently the operation of the operating device 10 desired by the person has been successful.
Insgesamt ist erkennbar, dass das Bedienelement 14 beziehungsweise eine Oberfläche 38 des Bedienelements 14 wenigstens einen Freiheitsgrad für die durch den ersten Aktor 26 bewirkbare Bewegung entlang der Bewegungsrichtung aufweist. Dieser Freiheitsgrad ist vorliegend derart realisiert, dass das Bedienelement 14 über die Federelemente 22 am Trägerelement 12 bewegbar gelagert ist. Sind keine Gegenmaßnahmen getroffen, so kann die Oberfläche 38, welche auch als Bedienteiloberfläche bezeichnet wird, durch den genannten Freiheitsgrad aus der Ruhestellung mit dem Finger 18 verschoben werden. Ist dabei beispielsweise das Fahrzeug deaktiviert oder berührt die Person das Bedienelement 14 an einer von den Betätigungsbereichen 16 unterschiedlichen Stelle, so kann die Person das Bedienelement 14 entlang der Bewegungsrichtung bewegen, ohne jedoch eine Funktion des Fahrzeugs zu bewirken. Diese Bewegbarkeit kann von der Person als negativ empfunden werden. Overall, it can be seen that the operating element 14 or a surface 38 of the operating element 14 has at least one degree of freedom for the movement which can be effected by the first actuator 26 along the direction of movement. In the present case, this degree of freedom is realized such that the operating element 14 is movably mounted on the carrier element 12 via the spring elements 22. If no countermeasures are taken, the surface 38, which is also referred to as the control panel surface, can be displaced from the rest position with the finger 18 by the stated degree of freedom. If, for example, the vehicle is deactivated or the person touches the operating element 14 at a position different from the operating areas 16, the person can move the operating element 14 along the direction of movement, without, however, effecting a function of the vehicle. This mobility can be perceived as negative by the person.
Um nun eine besonders vorteilhafte Bedienung der Bedienvorrichtung 10 sowie insbesondere einen wertigen Eindruck der Bedienvorrichtung 10 auf einfache Weise zu realisieren, umfasst die Bedienvorrichtung 10 eine im Ganzen mit 40 bezeichnete Fixiereinrichtung mit wenigstens einem mechanischen Fixierelement 42, welches zwischen wenigstens einer das Bedienelement 14 formschlüssig gegen eine Bewegung aus der Ruhestellung entlang der Bewegungsrichtung relativ zum Trägerelement 12 sichernden und in der Fig. gezeigten Fixierstellung und wenigstens einer das Bedienelement 14 freigebenden Freigabestellung bewegbar ist. Wie aus der Fig. erkennbar ist, greift das Fixierelement 42 in der Fixierstellung in eine relativ zum Bedienelement 14 unbewegbare und vorliegend am Bedienelement 14 vorgesehen Ausnehmung 44 ein, sodass das Fixierelement 42 in der Fixierstellung über die Ausnehmung 44 formschlüssig mit dem Bedienelement 14 zusammenwirkt. Infolge dieses formschlüssigen Zusammenwirkens kann die Person das Bedienelement 14 nicht aus der Ruhestellung entlang der Bewegungsrichtung relativ zum Trägerelement 12 bewegen, wenn sich das Fixierele- ment 42 in seiner Fixierstellung befindet. In order to realize a particularly advantageous operation of the operating device 10 and in particular a valued impression of the operating device 10 in a simple manner, the operating device 10 comprises a generally designated 40 fixing device with at least one mechanical fixing element 42 which between at least one of the control element 14 against form-fitting a movement from the rest position along the direction of movement relative to the carrier element 12 securing and in The fixing position shown in FIG. And at least one releasing position releasing the operating element 14 is movable. As can be seen from the figure, the fixing element 42 engages in the fixing position in a relative to the control element 14 immovable and presently provided on the operating element 14 recess 44, so that the fixing member 42 cooperates in the fixing position on the recess 44 form-fitting manner with the operating element 14. As a result of this positive cooperation, the person can not move the operating element 14 from the rest position along the direction of movement relative to the carrier element 12 when the fixing element 42 is in its fixing position.
Um beispielsweise Toleranzen auszugleichen und ein zumindest im Wesentlichen spielfreies Zusammenwirken zwischen dem Fixierelement 42 und dem Bedienelement 14 in der Fixierstellung zu realisieren, ist das Fixierelement 42 zumindest in einem Längenbereich keilförmig, insbesondere konisch, ausgebildet, wobei dieser keilförmige Längenbereich zumindest teilweise in die korrespondierende Ausnehmung 44 eingreift. Dadurch können unerwünschte Bewegungen des Bedienelements 14 entlang der Bewegungsrichtung relativ zum Trägerelement 12 sicher vermieden werden. For example, to compensate for tolerances and to realize an at least substantially backlash-free interaction between the fixing element 42 and the operating element 14 in the fixing position, the fixing element 42 is wedge-shaped, in particular conical, at least in one longitudinal region, this wedge-shaped longitudinal region at least partially into the corresponding recess 44 engages. As a result, unwanted movements of the operating element 14 along the direction of movement relative to the carrier element 12 can be reliably avoided.
Um erwünschte Bewegungen des Bedienelements 14 entlang der Bewegungsrichtung relativ zum Trägerelement 12 gezielt zuzulassen, ist ein vom ersten Aktor 26 unterschiedlicher, zweiter Aktor 46 vorgesehen, mittels welchem das Fixierelement 42 aus der Fixierstellung in die Freigabestellung bewegbar ist. Vorliegend ist der Aktor 46 als elektrischer Aktor und insbesondere als elektromagnetischer Aktor ausgebildet. Der zweite Aktor 46 um- fasst einen Zylinder 48 und eine Spule 50, welche mit elektrischem Strom versorgbar, das heißt bestrombar ist. Das Fixierelement 42 fungiert als Kolbenstange, welche zumindest teilweise in dem korrespondierenden Zylinder 48 aufgenommen und vorliegend mit diesem translatorisch mit bewegbar ist. Ferner ist ein dem Fixierelement 42 zugeordnetes Federelement 52 vorgesehen, welches zumindest in der Freigabestellung gespannt ist. Mittels des Federelements 52 ist das Fixierelement 42 unter zumindest teilweisem Entspannen des Federelements 52 aus der Freigabestellung in die Fixierstellung bewegbar und in der Fixierstellung gehalten. In order to specifically permit desired movements of the operating element 14 along the direction of movement relative to the carrier element 12, a second actuator 46 different from the first actuator 26 is provided, by means of which the fixing element 42 can be moved from the fixing position into the release position. In the present case, the actuator 46 is designed as an electrical actuator and in particular as an electromagnetic actuator. The second actuator 46 comprises a cylinder 48 and a coil 50, which can be supplied with electric current, ie can be supplied with current. The fixing element 42 acts as a piston rod, which is at least partially received in the corresponding cylinder 48 and in the present case with this translationally movable. Further, a fixing element 42 associated with the spring element 52 is provided, which is stretched at least in the release position. By means of the spring element 52, the fixing element 42 is movable under at least partial relaxation of the spring element 52 from the release position into the fixing position and held in the fixing position.
Ist beispielsweise das Fahrzeug aktiviert und wird eine von der Person bewirkte Betätigung beziehungsweise Bedienung des Bedienelements 14 er- fasst, so wird die Spule 50 bestromt. Infolge des Bestromens der Spule 50 wird das Fixierelement 42 elektromagnetisch aus der Fixierstellung in die Freigabestellung bewegt, wodurch das Federelement 52 gespannt wird. Dann kann das Bedienelement 14 mittels des ersten Aktors 26 bewegt werden, um dadurch die haptische Rückmeldung an die Person zu erzeugen. Befindet sich dann das Bedienelement 14 wieder in der Ruhestellung, so wird die Bestromung der Spule 50 beendet. In der Folge kann sich das Federelement 52 entspannen, wodurch das Fixierelement 42 wieder in die Fixierstellung bewegt wird. Vorzugsweise ist das Federelement 52 auch in der Fixierstellung noch etwas gespannt, sodass das Fixierelement 42 gegen das Bedienelement 14 beziehungsweise die Ausnehmung 44 noch vorgespannt und sicher in der Fixierstellung gehalten wird. If, for example, the vehicle is activated and an actuation or operation of the operating element 14 effected by the person is detected, the coil 50 is energized. As a result of energizing the coil 50 the fixing element 42 is electromagnetically moved from the fixing position into the release position, whereby the spring element 52 is tensioned. Then, the operating element 14 can be moved by means of the first actuator 26, thereby generating the haptic feedback to the person. If then the operating element 14 is again in the rest position, the energization of the coil 50 is terminated. As a result, the spring element 52 can relax, whereby the fixing element 42 is moved back into the fixing position. Preferably, the spring element 52 is still somewhat tensioned even in the fixing position, so that the fixing element 42 is still biased against the operating element 14 or the recess 44 and securely held in the fixing position.
Insgesamt ist erkennbar, dass das Fixierelement 42 als mechanisches Rastelement verwendet wird, mittels welchem das Bedienelement 14 in der Ru- hestellung relativ zum Trägerelement 12 entlang der Bewegungsrichtung fixiert beziehungsweise blockiert wird. Nur wenn das als elektromagnetisches Rastelement ausgebildete Fixierelement 42 durch Bestromen der Spule 50 in die Freigabestellung bewegt wird, können das Bedienelement 14 und somit seine Oberfläche 38 mittels des ersten Aktors 26 bewegt beziehungsweise beschleunigt werden. Mittels der Fixiereinrichtung 40, welche den zweiten Aktor 46, den Zylinder 48 und das Federelement 52 umfasst, kann somit eine exakte und unbewegliche Ruhestellung der Oberfläche 38 (Bedienteiloberfläche) geschaffen werden. Mit anderen Worten ist das Fixierelement 42 ein Rastbolzen, welcher mittels des Federelements 52 in die als Rastposition ausgebildete Fixierstellung gedrückt wird. Dadurch kann die Oberfläche 38 nicht mehr in die Bewegungsrichtung verschoben werden. Die Oberfläche 38 ist somit verriegelt. Soll nun die haptische Rückmeldung erzeugt werden, so wird die Spule 50 bestromt, wodurch der Rastbolzen in die Freigabestellung bewegt und vorliegend eingefahren wird. Nun hat die Oberfläche 38 ihren zuvor genannten Freiheitsgrad entlang der Bewegungsrichtung und kann somit mittels des ersten Aktors 26 bewegt beziehungsweise beschleunigt werden, wodurch unter Erzeugen der haptischen Rückmeldung ein Haptikimpuls auf den das Bedien- element 14 bedienenden Finger 18 übertragen wird. Overall, it can be seen that the fixing element 42 is used as a mechanical detent element, by means of which the operating element 14 is fixed or blocked in the rest position relative to the carrier element 12 along the direction of movement. Only when the fixing element 42 designed as an electromagnetic detent element is moved by energizing the coil 50 into the release position can the operating element 14 and thus its surface 38 be moved or accelerated by means of the first actuator 26. By means of the fixing device 40, which comprises the second actuator 46, the cylinder 48 and the spring element 52, thus an exact and immovable rest position of the surface 38 (control panel surface) can be created. In other words, the fixing element 42 is a latching pin, which is pressed by means of the spring element 52 in the locking position designed as a fixing position. As a result, the surface 38 can not be moved in the direction of movement. The surface 38 is thus locked. If now the haptic feedback is generated, the coil 50 is energized, whereby the locking pin is moved to the release position and retracted in the present case. The surface 38 now has its aforementioned degree of freedom along the direction of movement and can thus be moved or accelerated by means of the first actuator 26, whereby a haptic pulse is transmitted to the finger 18 operating the operating element 14 while generating the haptic feedback.
