DE 10 2007 005 882 A1 offenbart eine Anzeige mit mehreren schichtweise hintereinander angeordneten ansteuerbaren Anzeigeelementen, wobei die Anzeigeelemente im nicht angesteuerten Zustand transparent oder semitransparent und im angesteuerten Zustand leuchtend sind. DE 10 2007 005 882 A1 discloses a display with a plurality of controllable display elements arranged one behind the other in layers, wherein the display elements in the non-activated state are transparent or semitransparent and luminous in the activated state.
DE 10 2006 014 839 A1 beschreibt eine Einstellvorrichtung umfassend einen Drehgriffkörper mit einem Prisma, die teils einen axial, mittig im Drehgriffkörper liegenden Teil mit einer an einer äußeren Endseite des Drehgriffkörpers liegenden Symbolanzeigefläche aufweist, teils einen gewinkelt zum mittigen Teil liegenden Teil zur Aufnahme von einfallendem Licht von einem mit einer Lichtquelle beleuchteten Symbol auf einem stationären Scheibenelement, das sich auf einer von der äußeren Endseite weg gerichteten Seite des Drehgriffkörpers und konzentrisch zu diesem befindet, um abhängig von der Drehstellung des Drehgriffkörpers verschiedene Symbole durch optische Projektion auf die Symbolanzeigefläche anzuzeigen.

In GB 2376284 B wird eine Bedienvorrichtung mit einer Lichtquelle und mehreren Symbolen auf einer transparenten Folie, die sich dreht, offenbart. GB 2376284 B discloses an operating device having a light source and a plurality of symbols on a transparent film which rotates.
Es ist bekannt, Solltemperaturen für Klimaanlagen von Fahrzeugen auf Displays darzustellen. Soll eine solche Temperatur innerhalb eines Drehstellers angezeigt werden, so muss ein kleines Display in den Drehsteller eingebaut werden. Damit sich das Display nicht mitdreht, wenn der Drehsteller bedient wird, ist der Innenbereich des Drehstellers zu fixieren. Dies bedingt eine sehr teure und aufwendige Technik. Darüber hinaus kann nur ein begrenzter Bereich der Drehstelleroberfläche als Anzeige verwendet werden. It is known to display target temperatures for air conditioning systems of vehicles on displays. If such a temperature is to be displayed within a turntable, then a small display must be installed in the turntable. So that the display does not rotate when the turntable is operated, the interior of the turntable is to be fixed. This requires a very expensive and expensive technology. In addition, only a limited area of the turntable surface can be used as a display.
Davon ausgehend ergibt sich die Aufgabe, eine preisgünstige und trotzdem hochwertige Anzeige insb. einer Temperatur an einem Bedienelement einer Bedienvorrichtung zu realisieren. Based on this, the task results to realize a low-priced yet high-quality display esp. A temperature on a control element of an operating device.
Diese Aufgabe wird durch die im unabhängigen Patentanspruch angegebene Erfindung gelöst. Vorteilhafte Ausgestaltungen ergeben sich aus den abhängigen Ansprüchen. This object is achieved by the invention specified in the independent claim. Advantageous embodiments emerge from the dependent claims.
Dementsprechend weist eine Bedienvorrichtung für ein Kraftfahrzeug eine grafische Anzeigevorrichtung und ein Bedienelement auf. Das Bedienelement weist einen Lichtleiter zum Weiterleiten einer von der grafischen Anzeigevorrichtung angezeigten grafischen Anzeige auf. Unter dem Weiterleiten der von der grafischen Anzeigevorrichtung angezeigten grafischen Anzeige ist dabei ein Weiterleiten und Aufrechterhaltung der Grafik, also des Anzeigeinhalts zu verstehen. Accordingly, an operating device for a motor vehicle has a graphic display device and a control element. The operating element has an optical waveguide for forwarding a graphic display displayed by the graphic display device. The forwarding of the graphic display displayed by the graphic display device is to be understood as a forwarding and maintaining of the graphic, that is to say of the display content.
Vorzugsweise ist die von der grafischen Anzeigevorrichtung angezeigte grafische Anzeige am Lichtleiter sichtbar. Dazu endet bspw. der Lichtleiter an einer Oberfläche des Bedienelementes oder ist von einer Oberfläche des Bedienelements nur noch durch transparentes Material getrennt. Preferably, the graphical display displayed by the graphical display device is visible on the light pipe. For this ends, for example, the light guide to a surface of the control element or is separated from a surface of the control element only by transparent material.
Besonders einfach lässt sich die grafische Anzeige in Lichtleiter einkoppeln, wenn der Lichtleiter direkt an der grafischen Anzeigevorrichtung angeordnet ist. Dazu ist er bspw. auf der grafischen Anzeigevorrichtung befestigt, fixiert und/oder verklebt. Die grafische Anzeigevorrichtung weist vorzugsweise eine Segmentanzeige und/oder eine Pixelanzeige auf, durch die die grafische Anzeige angezeigt wird. Die grafische Anzeigevorrichtung ist dazu bspw. als Display, TFT, LED, LCD oder Plasmaanzeige realisiert. Weiter bevorzugt ist die grafische Anzeigevorrichtung berührungssensitiv, also bspw. ein Touchscreen. The graphic display can be coupled into light guides particularly simply if the light guide is arranged directly on the graphic display device. For this purpose it is, for example, attached, fixed and / or glued on the graphic display device. The graphical display device preferably has a segment display and / or a pixel display through which the graphical display is displayed. The graphic display device is realized, for example, as a display, TFT, LED, LCD or plasma display. More preferably, the graphical display device is touch-sensitive, so for example. A touch screen.
Insbesondere erstreckt sich der Lichtleiter zumindest teilweise durch das Bedienelement zur grafischen Anzeigevorrichtung. In particular, the light guide extends at least partially through the control element to the graphic display device.
Bevorzugt ist das Bedienelement ein Drehsteller mit einem Drehelement. Weiter bevorzugt ist das Drehelement um den Lichtleiter herum drehbar, wobei sich insb. der Lichtleiter beim Drehen des Drehelementes nicht mitdreht. Preferably, the control element is a turntable with a rotary member. More preferably, the rotary member is rotatable about the light guide around, wherein esp. The light guide does not rotate when turning the rotary member.
Durch eine Bedienen des Bedienelementes sind Signale zum Bedienen des Kraftfahrzeugs auslösbar. Durch diese Signale ist insb. eine Veränderung der von der grafischen Anzeigevorrichtung angezeigten grafischen Anzeige hervorrufbar. By operating the operating element signals for operating the motor vehicle can be triggered. In particular, a change in the graphic display displayed by the graphic display device can be caused by these signals.
Vorzugsweise ist das Bedienelement und/oder der Lichtleiter zylindrisch ausgeführt. Preferably, the control element and / or the light guide is cylindrical.
Die Bedienvorrichtung weist vorzugsweise eine Steuerungseinrichtung auf, die die grafische Anzeigevorrichtung zur grafischen Anzeige eines Temperaturwertes ansteuert, der am Lichtleiter sichtbar ist. The operating device preferably has a control device, which controls the graphic display device for the graphic display of a temperature value that is visible on the light guide.
Weitere Vorteile und Merkmale der Erfindung ergeben sich aus der Beschreibung eines Ausführungsbeispiels anhand der Zeichnung. Dabei zeigt: Further advantages and features of the invention will become apparent from the description of an embodiment with reference to the drawing. Showing:
Figur 1 eine Bedienvorrichtung mit einer grafischen Anzeigevorrichtung und einem Bedienelement in einer Seitenansicht und Figur 2 das Bedienelement aus Figur 1 in einer Draufsicht. 1 shows an operating device with a graphic display device and a control element in a side view and 2 shows the operating element of Figure 1 in a plan view.
In Figur 1 erkennt man eine Bedienvorrichtung 1 mit einer Anzeigevorrichtung 2, auf der ein Bedienelement angeordnet ist. Das Bedienelement weist einen zylindrischen Lichtleiter 4 auf, dessen Zylinderachse in Richtung einer Flächennormalen der flächig gestalteten grafischen Anzeigevorrichtung 2 verläuft. Der Lichtleiter 4 ist auf der grafischen Anzeigevorrichtung 2 fixiert, insb. verklebt. Der Lichtleiter 4 ist an seinem der grafischen Anzeigevorrichtung 2 abgewandten Ende mit einem Drehelement 3 umgeben. Das Drehelement 3 ist um den Lichtleiter 4 herum drehbar, so dass das Bedienelement als Drehsteller ausgebildet ist. Zwischen dem Drehelement 3 und der grafischen Anzeigevorrichtung 2 weist das Bedienelement eine Hülle 5 auf, die optional aber auch entfallen kann. FIG. 1 shows an operating device 1 with a display device 2 on which an operating element is arranged. The operating element has a cylindrical optical waveguide 4, the cylinder axis of which runs in the direction of a surface normal of the two-dimensional graphic display device 2. The light guide 4 is fixed on the graphic display device 2, esp. Glued. The light guide 4 is surrounded at its end remote from the graphic display device 2 with a rotary element 3. The rotary member 3 is rotatable about the light guide 4 around, so that the operating element is designed as a turntable. Between the rotary member 3 and the graphic display device 2, the control element has a shell 5, which may optionally be omitted.
Der zylindrische Lichtleiter 4 wird so innerhalb des Drehstellers integriert. Der Drehsteller mit integriertem Lichtleiter 4 ist optisch leitend auf der als Display ausgebildeten grafischen Anzeigevorrichtung 2 fixiert. Die grafische Anzeige in Form eines Bildes der grafischen Anzeigevorrichtung 2 wird durch den Lichtleiter 4 übertragen und auf der Oberfläche des Lichtleiters 4 und damit des als Drehsteller ausgebildeten Bedienelementes angezeigt. Da die grafische Anzeige in der grafischen Anzeigevorrichtung 2 entsteht, kann das Bedienelement gedreht werden, ohne dass sich die grafische Anzeige mitdreht. Dabei lässt sich wahlweise der Lichtleiter 4 in der Hülle 5 mitdrehen oder das Bedienelement ist so ausgeführt, dass nur das Drehelement 3 drehbar ist. In Figur 2 erkennt man wie eine Temperatur von 20°C an der Stirnseite des zylindrischen Lichtleiters 4 sichtbar ist, der vom Drehelement 3 umgeben ist. Die Temperatur wird dabei als grafische Anzeige von der grafischen Anzeigevorrichtung 2 angezeigt und durch den Lichtleiter 4 geleitet. Eine Bedienung des Bedienelementes wird insb. durch eine in der grafischen Anzeigevorrichtung 2 angeordnete Sensorik sensiert, die die Fingerposition und insb. Veränderungen der Fingerposition von das Drehelement 3 berührenden Fingern erfasst. The cylindrical optical fiber 4 is integrated within the turntable. The turntable with integrated light guide 4 is optically fixed on the display device 2 designed as a display. The graphic display in the form of an image of the graphic display device 2 is transmitted through the light guide 4 and displayed on the surface of the light guide 4 and thus of the designed as a turntable control. Since the graphic display is formed in the graphic display device 2, the operating element can be rotated without the graphic display rotating. In this case, optionally, the light guide 4 can rotate in the shell 5 or the operating element is designed so that only the rotary member 3 is rotatable. In Figure 2 it can be seen how a temperature of 20 ° C at the end face of the cylindrical light guide 4 is visible, which is surrounded by the rotary member 3. The temperature is displayed as a graphical display of the graphic display device 2 and passed through the light guide 4. Die Temperatur wird von der Temperatur von ca. An operation of the operating element is sensed in particular by a sensor device arranged in the graphic display device 2, which detects the finger position and in particular changes in the finger position of the fingers touching the rotary element 3.
Statt einer Temperatur können in der grafischen Anzeigevorrichtung 2 und damit im Lichtleiter 4 auch andere Soll- und Ist-Werte angezeigt werden. Das Bedienelement ist dann bevorzugt zum Bedienen von Einrichtungen des Kraftfahrzeugs ausgebildet, die mit diesen Soll- oder Ist-Werten in Zusammenhang stehen. Dazu ist dem Bedienelement jeweils eine entsprechende Sensorik zugeordnet. Instead of a temperature, other desired and actual values can also be displayed in the graphic display device 2 and therefore in the light guide 4. The operating element is then preferably designed for operating devices of the motor vehicle, which are associated with these desired or actual values. For this purpose, the control element is associated with a respective sensor.
