Bedienelement mit verbesserter KipphaptikControl element with improved tilt feel

Die vorliegende Erfindung betrifft ein Bedienelement für ein Kraftfahrzeug insbesondere einen in mehreren Richtungen kippbaren Joystick, mit einem Bedienknopf, einer in einem Gehäuse des Bedienelementes befindlichen Lagerstelle für den Bedienknopf, einer fest mit dem Bedienknopf verbundenen Verlängerung, einem an der Verlängerung befestigten ersten Permanentmagneten und einem im Gehäuse befestigten zweiten Permanentmagneten, wobei die Permanentmagnete ein Permanentmagnetpaar bilden und sich in einer Mittelstellung des Bedienknopfes ungleiche Pole der Magnete beabstandet gegenüber stehen.The present invention relates to a control for a motor vehicle, in particular a multi-directional tilting joystick, with a control knob, located in a housing of the control element bearing for the control knob, a permanently connected to the control knob extension, attached to the extension first permanent magnet and a fixed in the housing second permanent magnet, wherein the permanent magnets form a pair of permanent magnets and in a central position of the control knob unequal poles of the magnets are spaced from each other.

Kippbare Bedieneiemente werden in Kraftfahrzeugen dort eingesetzt, wo mittels eines Bedienelementes mehrere Funktionen ausführbar sind. Beispiele dafür sind Kippschalter für elektrische Fensterheber oder elektrisch verstellbare Außenspiegel sowie joystickartige Bedienelemente zur Steuerung eines Bordcomputers. Hierbei werden unter joystickartigen Bedienelementen derartige Bedienelemente verstanden, die zumindest in vier Richtungen kippbar sind, so dass mittels des joystickartigen Bedienelementes ein Menü in einem dem Bedienelement zugeordneten Anzeigesystem ansteuerbar ist. Für eine angenehmere Bedienung und zur haptischen Rückmeldung der Betätigung ist zur Bedienung des Bedienelementes eine über die Auslenkung veränderliche Kraft notwendig, über die dem Benutzer vermittelt wird, dass der Schaltvorgang erfolgt ist. Bei den bekannten Bedienelementen wird dieser Kraft-Weg-Verlauf üblicherweise durch eine oder mehrere Federn oder kooperierende Permanentmagnete erzeugt, die zusätzlich das Bedienelement in eine Mittelstellung zurückbringen, wenn es der Benutzer loslässt.Tilting Bedieneiemente be used in motor vehicles where several functions can be performed by means of a control element. Examples include toggle switches for power windows or electrically adjustable exterior mirrors and joystick-like controls for controlling an on-board computer. In this case, joystick-type operating elements are understood as meaning such operating elements which can be tilted at least in four directions, so that a menu in a display system assigned to the operating element can be activated by means of the joystick-type operating element. For a more pleasant operation and the haptic feedback of the operation, a force variable over the deflection is necessary for the operation of the operating element, via which the user is informed that the switching operation has taken place. In the known control elements of this force-displacement curve is usually generated by one or more springs or cooperating permanent magnets, which also bring the control back to a middle position when the user lets go.

Aus der DE 10 2006 002 634 A1 ist ein Bedienelement, insbesondere ein Joystick mit einer Kipphaptik für ein Kraftfahrzeug bekannt. Das Bedienelement weist einen kippbar gelagerten Hebel mit einem primären und mindestens einem sekundären Hebelarm sowie mindestens ein Permanentmagnetenpaar auf, wobei ein Magnet eines Permanentmagnetenpaares an einem sekundären Hebelarm und ein Magnet ortsfest im Bedienelement angeordnet ist. Hierbei stehen sich ungleiche Pole der Magnete derart gegenüber, dass das Bedienelement in einer Mittelstellung gehalten ist. Der Kraftverlauf über die Auslenkung des Bedienelementes hängt dabei ab von den Parametern: Länge des sekundären Hebelarms, Stärke der Permanentmagnete, physikalische Größe der Permanentmagnete und die Größe des Luftspalts zwischen den Magneten eines Permanentmagnetenpaares. Durch die Kraft zwischen den Magneten wird der sekundäre Hebelarm und damit der gesamte Hebel in der Mittelstellung gehalten. Zum Kippen des primären Hebelarms muss der Benutzer eine Kraft überwinden. Die Gegenkraft, die der Benutzer zum Kippen des primären Hebelarms überwinden muss, ist graphisch darstellbar, wobei nach einer Überwindung eines Kraftmaximums die Kraft zur Auslenkung des Hebels wieder abnimmt und schließlich nach einem Erreichen eines Endanschlags erneut ansteigt. Der Verlauf des für den Bediener des Bedienelementes fühlbaren Kraftanstiegs, Kraftabfalls und erneuten Kraftanstiegs wird hierbei als Haptik des Bedienelementes bezeichnet.From DE 10 2006 002 634 A1 a control element, in particular a joystick with a tilt-feel for a motor vehicle is known. The control element has a tiltably mounted lever with a primary and at least one secondary lever arm and at least one pair of permanent magnets, wherein a magnet of a pair of permanent magnets on a secondary lever arm and a magnet is arranged stationary in the operating element. Here, unequal poles of the magnets face each other in such a way that the operating element is held in a middle position. The force curve over the deflection of the control element depends on the parameters: length of the secondary lever arm, strength of the permanent magnets, physical size of the permanent magnets and the size of the air gap between the magnets of a permanent magnet pair. By the force between the magnets of the secondary lever arm and thus the entire lever is held in the center position. To tilt the primary lever arm, the user must overcome a force. The counterforce that the user must overcome to tilt the primary lever arm is graphically represented, wherein after overcoming a maximum force, the force for the deflection of the lever decreases again and finally increases again after reaching an end stop. The course of the force increase, force drop and force increase that can be felt by the operator of the operating element is referred to here as the feel of the operating element.

Die Aufgabe der Erfindung ist es, die Haptik eines Bedienelementes derart zu verändern, dass der Kraft-Weg-Verlauf, das heißt die Haptik des Bedienelementes gezielt einstellbar ist, wobei dies mit minimalem konstruktivem Aufwand und kostengünstig zu realisieren ist.The object of the invention is to change the feel of a control element such that the force-displacement curve, that is, the feel of the control element is specifically adjustable, this being realized with minimal design effort and cost.

Die erfindungsgemäße Aufgabe wird dadurch gelöst, dass an einem in dem Bedienelement angeordneten Permanentmagnetenpaar zumindest bereichsweise und/oder umfänglich ein magnetisch leitfähiger Werkstoff befestigt ist. Durch die erfindungsgemäße Ausbildung eines Bedienelementes ist nun die Möglichkeit geschaffen, vorhandene Bedienelemente mit minimalem konstruktivem Aufwand und somit kostengünstig in ihrem Haptikverlauf entscheidend zu beeinflussen. So ist es insbesondere ohne eine Veränderung der vorhandenen Magnete möglich, den Haptikverlauf in Bezug auf die Maximalkraft und den Weg zur Erreichung dieses Maximalkraftwertes gezielt zu beeinflussen. Es ist insbesondere möglich, die Höhe der Maximalkraft und somit das Moment am Bedienelement zu variieren, ohne die Stärke der Permanentmagnete oder deren physikalische Größe zu verändern. Es ist weiterhin die Möglichkeit geschaffen, mit minimal konstruktivem Aufwand und unter Beibehaltung der geometrischen Abmessungen vorhandener Permanentmagnetenpaare den Kraft-Weg-Verlauf der Haptik wesentlich zu beeinflussen.The object of the invention is achieved in that at least partially and / or circumferentially a magnetically conductive material is attached to a arranged in the control element permanent magnet pair. The inventive design of a control element, the possibility is now created to influence existing controls with minimal design effort and thus cost in their haptics crucial. Thus, it is possible, in particular without changing the existing magnets, to specifically influence the haptic profile with respect to the maximum force and the way to achieve this maximum force value. In particular, it is possible to vary the magnitude of the maximum force and thus the moment on the operating element without changing the strength of the permanent magnets or their physical size. It is further created the possibility to significantly influence the force-displacement curve of the haptic with minimal design effort and while maintaining the geometric dimensions of existing permanent magnet pairs.

Die Permanentmagnetenpaare sind entweder in runder Ausführung umfänglich oder im Falle einer flachen, rechteckigen oder quadratischen Ausführungsform der Permanentmagnete mit einem leitfähigen Werkstoff umgeben. In der Ummantelung beziehungsweise seitlichen Ergänzung der Permanentmagnete werden die äußeren magnetischen Feldlinien je nach Stärke und magnetischer Leitfähigkeit der Ummantelung mehr oder weniger stark gebündelt. Die Ummantelung besteht in der erfindungsgemäßen Form aus elektrisch-leitfähigen Werkstoffen oder seltene Erden, wie beispielsweise Sm2COi7, SmCo2 oder NdFeW.The permanent magnet pairs are either circumferentially circumferential or in the case of a flat, rectangular or square embodiment of the permanent magnets surrounded by a conductive material. In the sheathing or lateral addition of the permanent magnets, the outer magnetic field lines are more or less concentrated depending on the strength and magnetic conductivity of the sheath. The casing consists in the inventive form of electrically conductive materials or rare earths, such as Sm 2 COi 7 , SmCo 2 or NdFeW.

Nachfolgend wird die Erfindung anhand von Diagrammen und Skizzen an Ausführungsbeispielen erläutert. Es zeigen:The invention will be explained with reference to diagrams and sketches of exemplary embodiments. Show it:

Die Figuren 1a, 1 b und 1c zeigen eine Seitenansicht im Schnitt eines Bedienelementes 1 in drei verschiedenen Bedienpositionen, nach dem Stand der Technik. Das Gehäuse 9 des Bedienelementes 1 weist eine Ausnehmung auf, in der eine Kugel als Lagerstelle für einen Hebel angeordnet ist. Der Hebel besteht aus einem primären Hebelarm 2 und einem sekundären Hebelarm 9. Ein Ende des Hebelarms 2 ist fest mit der Kugel 4 verbunden, das andere Ende trägt eine Handhabe 3, in Form eines Bedienknaufs. Der sekundäre Hebelarm 5 ist mit einem Ende fest mit der Kugel 4 verbunden, das andere Ende trägt einen Permanentmagneten 6. Ein zweiter Permanentmagnet 7 ist derart im Gehäuse 9 angeordnet, dass in der Mittelstellung des primären Hebelarms 2 ein Luftspalt zwischen dem Magneten 6 und dem Magneten 7 besteht und sich ungleiche Pole der Magnete gegenüber stehen. Die Endanschläge 8 begrenzen den Bewegungsspielraum des sekundären Hebelarms 5 und damit ebenfalls des primären Hebelarms 2. Durch die Kraft zwischen den Magneten 6 und 7 wird der sekundäre Hebelarm 5 und damit der gesamte Hebel in der Mittelstellung gehalten. Zum Kippen des primären Hebelarms muss der Benutzer diese Kraft überwinden. Die Kraft F oder Gegenkraft, die der Benutzer zum weiteren Kippen des primären Hebelarms überwinden muss, ist in der Figur 2 über die Auslenkung s des primären Hebelarms 2 aufgetragen. Die Schnittdarstellung in Figur 1b zeigt das Bedienelement 1 mit leicht ausgelenktem primärem Hebelarm 2, wobei die in der Figur 1b dargestellte Position der gestrichelten Linie b aus dem Kraft-Weg-Diagramm der Figur 2 entspricht. Über die Kugel 4 wird die Kippbewegung des primären Hebelarms 2 auf den sekundären Hebelarm 5 übertragen. Diese Bewegung des Hebelarms 5 hat eine Relativbewegung der Magnete 6 und 7 zur Folge. In der in Figur 1 b dargestellten Position des Hebels ist die Kraft, die zum weiteren Kippen des Hebels notwendig ist, größer als die Kraft, die zum Kippen des Hebels aus der in Figur 1a dargestellten Position heraus notwendig ist. Aber der in Figur 1b dargestellten Auslenkung des Hebels ist die abstoßende Kraft zwischen den Nordpolen der Magnete 6 und 7 der anziehenden Kraft der ungleichen Pole der Magnete 6 und 7 entgegen gerichtet. Dies bedeutet, dass die von dem Benutzer aufzubringende Kraft, um den Hebel weiter zu kippen, abnimmt. Diese Abnahme der Rückstellkraft gibt dem Benutzer eine haptische Rückmeldung darüber, dass der Schaltvorgang erfolgt ist, wobei die Abnahme der Kraft von der Position B zur Position C in der Figur 2 als Snap bezeichnet wird. Im Idealfall entspricht der Abfall der Kraft oder der Snap etwa einem Drittel der Maximalkraft, die vom Benutzer aufzubringen ist.Figures 1a, 1 b and 1c show a side view in section of a control element 1 in three different operating positions, according to the prior art. The housing 9 of the control element 1 has a recess in which a ball is arranged as a bearing for a lever. The lever consists of a primary lever arm 2 and a secondary lever arm 9. One end of the lever arm 2 is fixedly connected to the ball 4, the other end carries a handle 3, in the form of a control knob. The secondary lever arm 5 is fixedly connected at one end to the ball 4, the other end carries a permanent magnet 6. A second permanent magnet 7 is arranged in the housing 9 such that in the middle position of the primary lever arm 2, an air gap between the magnet 6 and the Magnets 7 is made and opposite poles of the magnets are opposite. The end stops 8 limit the range of motion of the secondary lever arm 5 and thus also of the primary lever arm second By the force between the magnets 6 and 7 of the secondary lever arm 5 and thus the entire lever is held in the center position. To tilt the primary lever arm, the user must overcome this force. The force F or counterforce which the user has to overcome in order to further tilt the primary lever arm is plotted in FIG. 2 via the deflection s of the primary lever arm 2. The sectional view in FIG. 1b shows the operating element 1 with a slightly deflected primary lever arm 2, wherein the position shown in FIG. 1b corresponds to the dashed line b from the force-displacement diagram of FIG. About the ball 4, the tilting movement of the primary lever arm 2 is transmitted to the secondary lever arm 5. This movement of the lever arm 5 has a relative movement of the magnets 6 and 7 result. In the position of the lever shown in FIG. 1b, the force necessary for further tilting of the lever is greater than the force necessary for tilting the lever out of the position shown in FIG. 1a. But the deflection of the lever shown in Fig. 1b is directed against the repulsive force between the north poles of the magnets 6 and 7 of the attracting force of the unequal poles of the magnets 6 and 7. This means that the force to be applied by the user to further tilt the lever decreases. This decrease in the restoring force gives the user a haptic feedback that the switching operation has taken place, the decrease in the force from the position B to the position C in FIG. 2 being referred to as snap. Ideally, the drop in force or snap equals about one third of the maximum force that the user has to apply.

In der in Figur 1c dargestellten Position des Hebels liegt der sekundäre Hebelarm 5 an dem Endanschlag an. Der Endanschlag 8 bewirkt über den sekundären Hebelarm 5 und die Kugel 4 eine Begrenzung des Kippweges des primären Hebelarms 2. Bevorzugt ist der Endanschlag 8 elastisch ausgeführt, um eine sprunghaft ansteigende Gegenkraft zu verhindern. Durch die geringe Nachgiebigkeit des Materials des Endanschlages erfolgt eine schnelle, aber stetige Zunahme der Gegenkraft, wie sie im Auslauf der Kurve in Figur 2 dargestellt ist.In the position of the lever shown in Figure 1c, the secondary lever arm 5 abuts against the end stop. The end stop 8 causes via the secondary lever arm 5 and the ball 4 is a limitation of Kippweges the primary lever arm 2. Preferably, the end stop 8 is designed to be elastic, to prevent a sudden increase in drag force. Due to the low compliance of the material of the end stop is a fast but steady increase in the counterforce, as shown in the outlet of the curve in Figure 2.

In der Figur 3a sind die Permanentmagnetenpaare 6 und 7 losgelöst vom Bedienelement 1 dargestellt. Die Permanentmagnetenpaare bestehen aus einem Nordpol (dunkelgrau) und einem Südpol (hellgrau). Gegenüberliegende Pole der Magnete weisen somit eine unterschiedliche Polung auf, so dass die Handhabe 3 oder der Bedienknopf 3 in seiner Mittenstellung gehalten ist. In diesem Ausführungsbeispiel sind die Magnete flach und an ihren gegenüberliegenden Enden 10 ,11 zum Beispiel quadratisch oder rechteckig ausgebildet. Die Figur 3b zeigt ein Permanentmagnetenpaar 12, 13 mit auf beiden Seiten der Magnete 12,13 angeordneten Blechen 14, 15, 16, 17 aus einem die magnetischen Feldlinien leitenden Werkstoff. Die Bleche 14, 15, 16, 17 oder leitenden Auflagen 14, 15, 16, 17 bewirken eine Ausrichtung und Bündelung der die Magnete 12, 13 umgebenden magnetischen Feldlinien 18. Die Ausrichtung und Bündelung der magnetischen Feldlinien 18 ermöglicht erfindungsgemäß eine Erhöhung der maximalen Kraft F, ohne den Einsatz teurer und großvolumiger Permanentmagnete. Je nach Ausbildung, Werkstoff, Dicke und Anzahl der Bleche 14, 15, 16, 17 am Umfang der Permanentmagnete 12, 13 ist somit eine gezielte Steuerung des Kraft-Weg-Verlaufes und folglich der Haptik am Bedienelement möglich. So ist darüber hinaus ein Vorteil der Erfindung, dass bei einer Beibehaltung der Maximalkraft eine Erhöhung des Luftspaltes 19 zwischen den Permanentmagneten 12, 13 ermöglicht wird, was wiederum die Montage erleichtert. Darüber hinaus ist es ebenfalls vorstellbar, Permanentmagnete mit geringeren geometrischen Abmessungen einzusetzen, was sich wiederum positiv auf die Kosten der Bedienelemente auswirkt.In the figure 3a, the permanent magnet pairs 6 and 7 detached from the control element 1 are shown. The permanent magnet pairs consist of a north pole (dark gray) and a south pole (light gray). Opposite poles of the magnets thus have a different polarity, so that the handle 3 or the control knob 3 is held in its center position. In this embodiment, the magnets are flat and formed at their opposite ends 10, 11, for example, square or rectangular. FIG. 3b shows a pair of permanent magnets 12, 13 with metal sheets 14, 15, 16, 17 arranged on both sides of the magnets 12, 13, of a material which conducts the magnetic field lines. The sheets 14, 15, 16, 17 or conductive pads 14, 15, 16, 17 cause an alignment and bundling of the magnets 12, 13 surrounding magnetic field lines 18. The alignment and bundling of the magnetic field lines 18 according to the invention allows an increase in the maximum force F, without the use of expensive and bulky permanent magnets. Depending on the design, material, thickness and number of sheets 14, 15, 16, 17 on the circumference of the permanent magnets 12, 13 is thus a targeted control of the force-displacement curve and consequently the haptic on the control possible. Thus, in addition, an advantage of the invention is that, while maintaining the maximum force, an increase in the air gap 19 between the permanent magnets 12, 13 is made possible, which in turn facilitates the assembly. In addition, it is also conceivable to use permanent magnets with smaller geometric dimensions, which in turn has a positive effect on the cost of the controls.

In dem in der Figur 3b dargestellten Ausführungsform sind die Permanentmagnete 12, 13 flach ausgeführt, so dass die magnetisch leitenden Bleche flach an den seitlichen Enden der Permanentmagnete 12, 13 befestigbar sind. Im Falle der Ausbildung der Permanentmagnete 12, 13 als kreisrunde Permanentmagnete 12, 13 ist es dann erfindungsgemäß vorstellbar, die Permanentmagnete 12, 13 vollständig und umfänglich mit einem magnetisch leitenden Material zu umgeben. Die vollständige Ummantelung der Permanentmagnete 12, 13 ist natürlich ebenfalls bei flach ausgebildeten Permanentmagneten 12, 13 ausführbar.In the embodiment illustrated in FIG. 3b, the permanent magnets 12, 13 are made flat, so that the magnetically conductive metal sheets can be fastened flat at the lateral ends of the permanent magnets 12, 13. In the case of the formation of the permanent magnets 12, 13 as a circular permanent magnets 12, 13, it is then conceivable according to the invention to surround the permanent magnets 12, 13 completely and circumferentially with a magnetically conductive material. Of course, the complete sheathing of the permanent magnets 12, 13 is also executable with flat permanent magnets 12, 13.

In der Figur 4 ist ein Kraft-Weg-Diagramm dargestellt. Ausgehend von einer Mittelstellung wird auf das Bedienelement eine Kraft ausgeübt, die bis zu einem gewissen Punkt F1 , S1 ansteigt, wobei dieser Punkt F1 , S1 der Kraft F1 und dem Weg S1 entspricht, der die maximal zu überwindende Anziehungskraft zwischen den sich gegenüber liegenden Permanentmagneten 12, 13 entspricht. Beispielhaft kann hier eine Relativbewegung zwischen den Permanentmagneten von S1 = 0,8 mm genannt sein. Nach der Überwindung der Maximalkraft F1 sinkt die Kraft ab, bis zu einer Kraft F2 im Punkt S2, wobei sich nun gleichartige Pole der Permanentmagnete 12, 13 gegenüberstehen, so dass der Bedienknopf aus dieser Lage, ohne die Einwirkung des Bedieners wieder in seine Mittenstellung zurückbewegen würde. Die Kraft im Diagramm der Figur 4 steigt nach dem Erreichen des Punktes F2, S2 erneut an, bis zum Erreichen einer Kraft F3 nach dem Weg S3, wobei dieser Punkt F3, S3 dem Erreichen des Endanschlages im Bedienelement entspricht. Der Abfall der Kraft von F1 zu F2 ist im Idealfall etwa ein Drittel von F1 und mit einem Wert von 35 % plus 10 % minus 5 % bezifferbar. F1 sowie der Weg S3 variiert hierbei je nach Anwendung und einzustellender bzw. vorgegebener Haptik. Beispielhaft sei für den Weg S3 ein Weg von S3 = 1 ,5 mm angebbar. Der Punkt des Abstoßens zwischen den Permanentmagneten 12, 13 wird nicht erreicht, so dass sich der Bedienknopf nach der Betätigung stets wieder in seine Mittenstellung selbsttätig zurückbewegt. Der Weg S1 ist mit 45 Prozent von S3 und einer Toleranz von plus 5 % und minus 10 % angebbar. Der Weg S2 ist mit S2 = 1 ,7 x S1 angebbar, wobei eine Toleranz von plus/minus 10 % möglich ist.FIG. 4 shows a force-displacement diagram. Starting from a middle position, a force is exerted on the operating element which rises to a certain point F1, S1, this point F1, S1 corresponding to the force F1 and the path S1, the maximum force of attraction to be overcome between the opposing permanent magnets 12, 13 corresponds. By way of example, a relative movement between the permanent magnets of S1 = 0.8 mm may be mentioned here. After overcoming the maximum force F1, the force decreases, up to a force F2 at the point S2, with now similar poles of the permanent magnets 12, 13 face, so that the control knob from this position, without the action of the operator back to its center position would. The force in the diagram of Figure 4 rises after reaching the point F2, S2 again, until reaching a force F3 on the way S3, this point F3, S3 corresponds to the reaching of the end stop in the control. The drop in force from F1 to F2 is ideally about one-third of F1 and at a value of 35% plus 10% minus 5% quantifiable. F1 as well as the path S3 varies depending on the application and the haptics to be set or predetermined. By way of example, a path of S3 = 1.5 mm can be specified for the path S3. The point of repulsion between the permanent magnets 12, 13 is not reached, so that the control knob automatically moves back to its center position automatically after actuation. The S1 path can be specified with 45 percent of S3 and a tolerance of plus 5% and minus 10%. The path S2 can be specified with S2 = 1.7x S1, whereby a tolerance of plus / minus 10% is possible.

In der Figur 5 ist ein erfindungsgemäß ausgebildetes Bedienelement in seinen wesentlichen Bestandteilen im Schnitt und in der Seitenansicht wiedergegeben. Das Bedienelement 20 besitzt einen primären Hebelarm 21 , zur Aufnahme eines nicht gezeigten Bedienknopfes, eine Lagerstelle 22, in Form einer kugelförmigen Lagerung 22, einen sekundären Hebelarm 23, wobei primärer und sekundärer Hebelarm 21 , 23 in einer Mittellinie oder Mittelachse 24 fluchtend übereinander angeordnet sind. Am sekundären Hebelarm 23 sind Ausleger 25, 26 befestigt. Am Ausleger 26 ist ein Permanentmagnet 27 befestigt, der mit einem Permanentmagneten 28 zusammenwirkt, wobei der Permanentmagnet 28 in einem fest mit dem Gehäuse des Bedieneiementes 20 verbundenen oder einen Teil des Gehäuses bildenden Bodenteil 29 des Bedienelementes 20 befestigt ist. Die Permanentmagnete 27, 28 bilden ein Permanentmagnetenpaar 27, 28, wobei sich die gegenüber liegenden Pole der Permanentmagnete 27, 28 unterscheiden, so dass die Hebelarme 21 , 23 in einer Mittenstellung gehalten sind. Bevorzugt sind zwei Ausleger 26 mit je einem Permanentmagnetenpaar 27, 28 im Bedienelement 20 um 90 Grad versetzt im Bedienelement 20 eingebaut. Der Ausleger 25 ist um 180 Grad versetzt am sekundären Hebelarm 23 befestigt. Der Ausleger 25 wirkt mit Mitteln zur Positionserkennung und zur Erfassung des Weges F der Auslenkung des Hebels 23 zusammen. Vorstellbar ist hierbei zum Beispiel der Einsatz von fotosensitiven oder induktiven Sensoren. In diesem Ausführungsbeispiel sind ebenfalls zwei Ausleger 25 um je 90 Grad versetzt am sekundären Hebelarm 23 angeordnet.In the figure 5 an inventively designed control element is shown in its essential components in section and in side view. The control element 20 has a primary lever arm 21, for receiving a control knob, not shown, a bearing 22, in the form of a spherical bearing 22, a secondary lever arm 23, wherein primary and secondary lever arm 21, 23 in a center line or central axis 24 are arranged one above the other in alignment , At the secondary lever arm 23 boom 25, 26 are attached. On the boom 26, a permanent magnet 27 is fixed, which cooperates with a permanent magnet 28, wherein the permanent magnet 28 is fixed in a fixed to the housing 20 of the Bedieneiementes or part of the housing forming the bottom part 29 of the control element 20. The permanent magnets 27, 28 form a permanent magnet pair 27, 28, wherein the opposite poles of the permanent magnets 27, 28 differ, so that the lever arms 21, 23 are held in a central position. Preferably, two jibs 26, each with a permanent magnet pair 27, 28 in the operating element 20 offset by 90 degrees in the control element 20 are installed. The boom 25 is offset by 180 degrees attached to the secondary lever arm 23. The boom 25 cooperates with means for detecting the position and for detecting the path F of the deflection of the lever 23. It is conceivable, for example, the use of photosensitive or inductive sensors. In this embodiment, two extension arms 25 are also arranged offset by 90 degrees on the secondary lever arm 23.

Aus dem sekundären Hebelarm 23 steht ein Stift 30 heraus, der mit elastischen Endanschlägen 31 zusammenwirkt und somit die Kippbewegung des Hebels 21 , 23 begrenzt. Die Bewegung des Stifts 30 in Richtung des Endanschlags 31 entspricht dem Weg S3 von ca. 1 ,5 mm. Wie der Figur 5 und dem darin dargestellten Ausführungsbeispiel deutlich zu entnehmen ist, werden die Permanentmagnete 27, 28 nicht so weit ausgelenkt, dass es zu einem Abstoßen der sich gegenüberliegenden Pole der Permanentmagnete 27, 28 kommt. Durch die Einbindung der erfindungsgemäßen magnetisch leitenden Werkstoffe, wie beispielsweise Blechen, ist es möglich, zum einen das Kraftmaximum F1 zu erhöhen und gleichzeitig den Weg S1 zu verringern. Dicke Bleche verringern die Maximalkraft F1 , so dass der Weg S1 verschiebbar wird. Es ist somit möglich, den Haptikverlauf, das heißt den Verlauf der haptischen Kurve aus dem Kraft-Weg-Diagramm zu variieren und exakt einzustellen. Durch den Einsatz der erfindungsgemäß magnetisch leitenden Werkstoffe, wie weichmagnetische Werkstoffe, Elektrobleche oder seltene Erden auf den Permanentmagneten 27, 28 werden die Feldlinien gebündelt, so dass die Maximalkraft um 50 % bis 100 % steigerbar ist.From the secondary lever arm 23 is a pin 30 out, which cooperates with elastic end stops 31 and thus limits the tilting movement of the lever 21, 23. The movement of the pin 30 in the direction of the end stop 31 corresponds to the distance S3 of approximately 1.5 mm. As can be seen clearly from FIG. 5 and the exemplary embodiment illustrated therein, the permanent magnets 27, 28 are not deflected so far that repulsion of the opposite poles of the permanent magnets 27, 28 occurs. By incorporating the magnetically conductive materials according to the invention, such as sheets, it is possible, on the one hand to increase the maximum force F1 and at the same time to reduce the path S1. Thick plates reduce the maximum force F1, so that the path S1 is displaced. It is thus possible to vary the Haptikverlauf, ie the course of the haptic curve from the force-displacement diagram and adjust exactly. By using the magnetically conductive materials according to the invention, such as soft magnetic materials, electrical sheets or rare earths on the permanent magnets 27, 28, the field lines are bundled, so that the maximum force can be increased by 50% to 100%.

Die Ausbildung des elastischen Endanschlags 31 im Bodenteil 29 des Bedienelementes 20 ist ebenfalls als Kulissenführung 31 nutzbar. Hierbei würde das elastische Element 31 zum Beispiel eine Kreuznut 32 aufweisen, in der der Stift 30 geführt ist. Eine Kulissenführung ist aber nur bedingt notwendig, da durch den Einsatz der magnetisch leitenden Materialien um die Permanentmagnete 27, 28 eine ausreichende Führung gewährleisten.The formation of the elastic end stop 31 in the bottom part 29 of the operating element 20 can also be used as a slide guide 31. In this case, the elastic element 31 would, for example, have a cross-groove 32 in which the pin 30 is guided. However, a slotted guide is only conditionally necessary, since by the use of magnetically conductive materials around the permanent magnets 27, 28 ensure adequate guidance.

Wie in der gattungsbildenden DE 10 2006 002 634 A1 beschrieben, eignet sich der Einsatz von Perrnanentmagnetenpaaren auch für den Einsatz von Drucktasten. Hierbei ist an den Bedienknopf eine Verlängerung einstückig oder zumindest kraftschlüssig angebaut, wobei an der Verlängerung ein erster Permanentmagnet befestigt ist. Im Gehäuse ist ein zweiter Permanentmagnet befestigt, wobei die Permanentmagnete ein Permanentmagnetenpaar bilden und sich in einer Ausgangsstellung des Bedienknopfes des Drucktasters ungleiche Pole der Magnete beabstandet gegenüberstehen und an den Permanentmagnetenpaaren zusätzlich ein die magnetischen Feldlinien leitender Werkstoff befestigt ist. Der Kraft-Weg-Verlauf einer Drucktaste entspricht im Wesentlichen der eines joystickartigen Bedienelementes (20), wobei lediglich der Bedienknopf und die Verlängerung eine lineare Bewegung in Richtung des Bedienelementes ausführen. As described in the generic DE 10 2006 002 634 A1, the use of permanent magnet pairs is also suitable for the use of pushbuttons. In this case, an extension is attached to the control knob in one piece or at least non-positively, wherein a first permanent magnet is attached to the extension. In the housing, a second permanent magnet is fixed, wherein the permanent magnets form a pair of permanent magnets and spaced apart in an initial position of the control knob of the pushbutton unequal poles of the magnets and on the permanent magnet pairs in addition a magnetic field lines conductive material is attached. The force-displacement curve of a pushbutton essentially corresponds to that of a joystick-type operating element (20), wherein only the control button and the extension execute a linear movement in the direction of the operating element.
