BESCHREIBUNG: DESCRIPTION:
Die Erfindung betrifft ein Head-up-Display für einen Kraftwagen der im Oberbegriff des Patentanspruchs 1 angegebenen Art. Des Weiteren betrifft die Erfindung einen Kraftwagen mit einem Head-up-Display sowie ein Verfahren zum Anordnen eines Head-up-Displays in einem Kraftwagen. The invention relates to a head-up display for a motor vehicle specified in the preamble of claim 1. Art Furthermore, the invention relates to a motor vehicle with a head-up display and a method for arranging a head-up display in a motor vehicle.
Die DE 10 2010 002 956 A1 zeigt ein Head-up-Display für einen Kraftwagen, welches eine bildgebende Einheit und ein Spiegelmodul zum Umlenken eines von der bildgebenden Einheit aussendbaren Strahlengangs aufweist. Das Spiegelmodul umfasst unterschiedliche Spiegelflächen, welche in den Strahlengang bewegbar sind. Dies dient dazu, eine einfache und schnelle Umschaltung der mittels des Head-up-Displays angezeigten Inhalte zwischen verschiedenen Fokussierungsebenen beziehungsweise Darstellungsweisen zu ermöglichen. DE 10 2010 002 956 A1 shows a head-up display for a motor vehicle, which has an imaging unit and a mirror module for deflecting a beam path that can be emitted by the imaging unit. The mirror module comprises different mirror surfaces, which are movable in the beam path.

Die DE 10 2007 047 232 A1 zeigt ebenfalls ein Head-up-Display für einen Kraftwagen, wobei ein Spiegel des Head-up-Displays flexibel positioniert werden kann, um einen Einbau in verschiedenen Fahrzeugtypen zu ermöglichen. DE 10 2007 047 232 A1 also shows a head-up display for a motor vehicle, wherein a mirror of the head-up display can be flexibly positioned to allow installation in different types of vehicles.
Die DE 10 2007 010 381 A1 zeigt auch ein Head-up-Display für einen Kraftwagen, wobei das Head-up-Display eine Basisbaugruppe mit zwei Spiegeln zum Einbau in verschiedenen Fahrzeugtypen aufweist. Es ist die Aufgabe der vorliegenden Erfindung, die Verwendung eines Head- up-Displays in unterschiedlichen Fahrzeugtypen auf vereinfachte Weise zu ermöglichen. Diese Aufgabe wird durch ein Head-up-Display für einen Kraftwagen, einen Kraftwagen mit einem Head-up-Display und durch ein Verfahren zum Anordnen eines Head-up-Displays in einem Kraftwagen mit den Merkmalen der unabhängigen Patentansprüche gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen und nicht-trivialen Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben. DE 10 2007 010 381 A1 also shows a head-up display for a motor vehicle, wherein the head-up display has a base assembly with two mirrors for installation in different vehicle types. It is the object of the present invention to enable the use of a head-up display in different types of vehicles in a simplified manner. This object is achieved by a head-up display for a motor vehicle, a motor vehicle with a head-up display and by a method for arranging a head-up display in a motor vehicle with the features of the independent claims. Advantageous embodiments with expedient and non-trivial developments of the invention are specified in the dependent claims.
Das erfindungsgemäße Head-up-Display für einen Kraftwagen umfasst zumindest eine bildgebende Einheit zum Aussenden einer Abbildung in Form eines Strahlengangs und zumindest ein Spiegelmodul zum Umlenken des von der bildgebenden Einheit aussendbaren Strahlengangs, wobei das Spiegelmodul wenigstens zwei unterschiedliche Spiegel aufweist, welche in den Strahlengang bewegbar sind. Das erfindungsgemäße Head-up-Display zeichnet sich dabei dadurch aus, dass eine jeweilige Krümmung der Spiegel an jeweilige fahrzeugspezifische Windschutzscheibenvarianten angepasst ist. Das erfindungsgemäße Head-up-Display kann auch durchaus mehrere bildgebende Einheiten und Spiegelmodule aufweisen. The inventive head-up display for a motor vehicle comprises at least one imaging unit for emitting an image in the form of a beam path and at least one mirror module for deflecting the emanating from the imaging unit beam path, wherein the mirror module has at least two different mirrors, which in the beam path are movable. The inventive head-up display is characterized in that a respective curvature of the mirror is adapted to respective vehicle-specific windshield variants. The inventive head-up display can also have several imaging units and mirror modules.
Die zumindest eine bildgebende Einheit ist also dazu ausgebildet, eine be- stimmte Abbildung, beispielsweise Geschwindigkeitsangaben, Navigationshinweise oder dergleichen, anzuzeigen. Das Spiegelmodul ist dabei derart angeordnet, dass üblicherweise ein Fahrer über das Spiegelmodul die mittels der bildgebenden Einheit angezeigte Abbildung sehen kann. Die Abbildung nimmt der Fahrer dann zum Beispiel in 2 Meter Entfernung schwebend über einer Motorhaube des betreffenden Kraftwagens wahr. The at least one imaging unit is therefore designed to display a specific image, for example speed information, navigation instructions or the like. The mirror module is arranged in such a way that usually a driver can see the image displayed by means of the imaging unit via the mirror module. The figure is then perceived by the driver, for example, hovering over a bonnet of the motor vehicle in question, 2 meters away.
Es ist somit erfindungsgemäß vorgesehen, dass das Head-up-Display also ein Spiegelmodul mit unterschiedlich ausgebildeten Krümmungswinkeln aufweist. Dadurch ist es möglich, das Head-up-Display für unterschiedliche Fahrzeuge und Scheiben einzusetzen. Die eigentliche Baugruppe, aus welcher das Head-up-Display zusammengesetzt ist, kann somit fahrzeugvarian- ten- und insbesondere auch windschutzscheibenvariantenunabhängig verwendet werden, ohne dass irgendwelche Komponenten des Head-up- Displays ausgetauscht werden müssen. Die Anzahl der unterschiedlichen Spiegel des Spiegelmoduls ist dabei nicht auf die zumindest zwei unterschiedlichen Spiegel begrenzt. Stattdessen kann es auch vorgesehen sein, dass das Spiegelmodul mehr als zwei Spiegel, beispielsweise drei, vier oder auch fünf unterschiedliche Spiegel aufweist, deren jeweilige Krümmungen an jeweilige fahrzeugspezifische Windschutzscheibenvarianten angepasst sind. Je mehr Spiegel das Spiegelmodul mit jeweils unterschiedlichen Krümmungen aufweist, desto universeller ist das gesamte Head-up-Display ohne den Austausch irgendwelcher Komponenten fahrzeug- und windschutzscheiben- variantenübergreifend einsetzbar. It is thus provided according to the invention that the head-up display thus has a mirror module with differently shaped angles of curvature. This makes it possible to use the head-up display for different vehicles and discs. The actual assembly, from which the head-up display is composed, can thus be used independently of the vehicle variant and, in particular, also in windshield variants, without having to exchange any components of the head-up display. The number of different mirrors of the mirror module is not limited to the at least two different mirrors. Instead, it can also be provided that the mirror module has more than two mirrors, for example three, four or even five different mirrors whose respective curvatures are adapted to respective vehicle-specific windshield variants. The more mirrors the mirror module has, each with different curvatures, the more universal the entire head-up display can be used without the replacement of any components of vehicle and windshield variants.
Eine vorteilhafte Ausführungsform der Erfindung sieht vor, dass die jeweilige Krümmung der Spiegel an jeweilige fahrzeugspezifische Krümmungen der Windschutzscheibenvarianten angepasst ist. Dadurch kann der Tatsache Rechnung getragen werden, dass bei unterschiedlichen Fahrzeugen insbe- sondere unterschiedliche Windschutzscheibenvarianten mit unterschiedlich starken Krümmungen eingesetzt werden, sodass durch die jeweils an die fahrzeugspezifischen Krümmungen der Windschutzscheiben angepassten Krümmungen der eingesetzten Spiegel des Spiegelmoduls der Einsatz von ein und demselben Head-up-Display bei unterschiedlichen Fahrzeugen er- folgen kann. An advantageous embodiment of the invention provides that the respective curvature of the mirror is adapted to respective vehicle-specific curvatures of the windshield variants. In this way, it is possible to take account of the fact that different windshield variants with different degrees of curvature are used in different vehicles, so that the use of one and the same head-up is achieved by the respective curvatures of the mirrors used in the vehicle-specific curvatures of the windshields Display on different vehicles.
Gemäß einer weiteren vorteilhaften Ausführungsform der Erfindung ist es vorgesehen, dass die jeweilige Krümmung der Spiegel an jeweilige fahrzeugspezifische Herstelltoleranzen der Windschutzscheibenvarianten ange- passt ist. Zum einen können bei der Herstellung der Scheiben an sich die Abmaße und Krümmungen der Scheiben leicht variieren, je nachdem, welche Herstelltoleranzen vorgegeben sind. Üblicherweise werden moderne Windschutzscheiben als Verbundglasscheiben hergestellt, welche eine erste Scheibe und eine zweite Scheibe aufweisen, die über eine Folie miteinander verbunden sind. Dabei können gewisse Dickentoleranzen beziehungsweise Dickenschwankungen bei derartigen Verbundscheiben auftreten, wobei die jeweiligen Krümmungen der Spiegel beispielsweise an derartige fahrzeugspezifische beziehungsweise windschutzscheibenvariantenspezifische Toleranzen angepasst sein können. Ferner können auch bei der Montage der Scheiben an dem Kraftwagen unterschiedliche Maßtoleranzen erlaubt sein, sodass die Windschutzscheiben nicht immer exakt gleich gegenüber dem Kraftwagen positioniert sind. Auch dies kann beispielsweise durch die jeweiligen Krümmungen der Spiegel berücksichtigt werden. In weiterer vorteilhafter Ausgestaltung der Erfindung ist es vorgesehen, dass das Head-up-Display zumindest einen Faltspiegel und zumindest einen Asphärenspiegel aufweist, welcher ausgehend von der bildgebenden Einheit in Richtung des Strahlengangs hinter dem Faltspiegel angeordnet ist, wobei der Faltspiegel und/oder der Asphärenspiegel als das Spiegelmodul ausge- bildet ist. Durch das aus dem Faltspiegel und dem Asphärenspiegel ausgebildete optische System wird der Strahlengang künstlich verlängert. Der Asphärenspiegel, welcher auch als Konkavspiegel, Hauptspiegel oder Korrekturspiegel bezeichnet wird, parallelisiert dabei die Lichtstrahlen des Strah- lengangs, vergrößert üblicherweise die Abbildung des Head-up-Displays und gleicht üblicherweise Verzerrungen aus, die durch die Krümmung der Windschutzscheibe entstehen. Der Asphärenspiegel kann dabei konkav oder konvex ausgebildet sein. Falls der Asphärenspiegel konkav ausgebildet ist, vergrößert dieser die von der bildgebenden Einheit bereitgestellte Abbildung. Falls der Asphärenspiegel konvex ausgebildet ist, kann dieser er den Strahlengang verlängern. Mit dem Faltspiegel wird der Strahlengang gefaltet. Durch diese Maßnahmen wird erreicht, dass das mittels des Head-up- Displays angezeigte virtuelle Bild in einem vorbestimmten Abstand, beispielsweise in zwei Meter Entfernung von einem Betrachter knapp über der Motorhaube des Kraftwagens, sichtbar wird. Je nach Packaging, also Bauraumsituation innerhalb des Kraftwagens, kann das Spiegelmodul dabei entweder den Faltspiegel und/oder den Asphärenspiegel ausbilden, um so eine Anpassung des Head-up-Displays an jeweilige fahrzeugspezifische Windschutzscheibenvarianten zu ermöglichen. According to a further advantageous embodiment of the invention, it is provided that the respective curvature of the mirror is adapted to respective vehicle-specific manufacturing tolerances of the windshield variants. Firstly, in the manufacture of the discs per se, the dimensions and curvatures of the discs can vary slightly, depending on which manufacturing tolerances are given. Conventionally, modern windshields are produced as laminated glass panes which have a first pane and a second pane which are interconnected by a foil. In this case, certain thickness tolerances or thickness variations may occur in such composite panes, wherein the respective curvatures of the mirror can be adapted, for example, to such vehicle-specific or windshield variant specific tolerances. Furthermore, different dimensional tolerances may also be allowed during the assembly of the panes on the motor vehicle, so that the windshields are not always positioned exactly equal to the motor vehicle. This too can be taken into account, for example, by the respective curvatures of the mirrors. In a further advantageous embodiment of the invention, it is provided that the head-up display has at least one folding mirror and at least one aspheric mirror, which is arranged starting from the imaging unit in the direction of the beam path behind the folding mirror, wherein the folding mirror and / or the aspherical mirror as the mirror module is forming. By formed from the folding mirror and the aspheric mirror optical system of the beam path is artificially extended. The aspheric mirror, which is also referred to as a concave mirror, primary mirror or correction mirror, parallelises the light rays of the beam path, usually enlarges the image of the head-up display and usually compensates for distortions that result from the curvature of the windshield. The aspheric mirror can be concave or convex. If the aspheric mirror is concave, it enlarges the image provided by the imaging unit. If the aspheric mirror is convex, it can extend the beam path. With the folding mirror the beam path is folded. By means of these measures it is achieved that the virtual image displayed by means of the head-up display becomes visible at a predetermined distance, for example two meters away from a viewer just above the engine hood of the motor vehicle. Depending on the packaging, so space situation within the motor vehicle, the mirror module can form either the folding mirror and / or the aspheric mirror, so as to allow an adjustment of the head-up display to respective vehicle-specific windshield variants.
Eine weitere vorteilhafte Ausführungsform der Erfindung sieht vor, dass das Spiegelmodul derart translatorisch bewegbar ausgebildet ist, dass. zum Verändern einer virtuellen Bilddistanz ein Abstand in Richtung des Strahlengangs zwischen dem Faltspiegel und dem Asphärenspiegel veränderbar ist. Je nach Präferenz eines Benutzers kann also das Spiegelmodul derart translatorisch bewegt werden, dass die virtuelle Bilddistanz auf einfache Weise verändert werden kann. A further advantageous embodiment of the invention provides that the mirror module is designed to be translationally movable such that a distance in the direction of the beam path between the folding mirror and the aspheric mirror can be changed to change a virtual image distance. Depending on the preference of a user, the mirror module can thus be moved in a translatory manner such that the virtual image distance can be changed in a simple manner.
Gemäß einer weiteren vorteilhaften Ausführungsform der Erfindung ist es vorgesehen, dass das Spiegelmodul derart drehbar ausgebildet ist, dass die jeweiligen Spiegel des Spiegelmoduls in den Strahlengang verschwenkbar sind. Dadurch können die unterschiedlichen Spiegel mit den jeweils unterschiedlichen Krümmungen auf besonders einfache Weise in den Strahlengang bewegt werden. According to a further advantageous embodiment of the invention, it is provided that the mirror module is designed to be rotatable such that the respective mirrors of the mirror module can be pivoted into the beam path. As a result, the different mirrors with the respective different curvatures can be moved in a particularly simple manner into the beam path.
In weiterer vorteilhafter Ausgestaltung der Erfindung ist es vorgesehen, dass das Head-up-Display einen Aktuator aufweist, mittels welchem das Spiegelmodul verdrehbar und/oder translatorisch bewegbar ist. Zum einen kann das Spiegelmodul dadurch besonders exakt und zum anderen auch besonders einfach wunschgemäß positioniert werden.

Beispielsweise kann eine derartige Bedieneinrichtung in einem Cockpit des Kraftwagens angeordnet sein, sodass zum Beispiel ein Fahrer durch die Betätigung der Bedieneinrichtung den Abstand zwischen dem Faltspiegel und dem Asphärenspiegel derart verändern kann, dass eine für ihn wunschgemäße virtuelle Bilddistanz eingestellt wird. Zudem ist es auch möglich, dass durch Betätigung der Bedieneinrichtung bereits während der Montage des Head- up-Displays mit Hilfe des Aktuators das Spiegelmodul derart verdreht wird, dass der für die jeweilige Windschutzscheibenvariante passende Spiegel mit der entsprechenden Krümmung in den Strahlengang verdreht werden kann. A further advantageous embodiment of the invention provides that the head-up display has an operating device, by the actuation of the actuator for moving the mirror is controlled. For example, such an operating device can be arranged in a cockpit of the motor vehicle, so that, for example, a driver can change the distance between the folding mirror and the aspherical mirror by operating the operating device in such a way that a desired virtual image distance is set for him. In addition, it is also possible that the mirror module is rotated in such a way by actuation of the operating device already during assembly of the head-up display with the aid of the actuator, that the suitable for the respective windshield variant mirror can be rotated with the corresponding curvature in the beam path.

Ein insgesamt mit 10 bezeichnetes Head-up-Display ist in einer schematischen Darstellung in der einzigen Figur gezeigt. Das Head-up-Display 10 umfasst eine bildgebende Einheit 12, einen Faltspiegel 14 sowie ein Spiegelmodul 16. Das Spiegelmodul 16 weist vorliegend drei unterschiedlich gekrümmte Spiegel 18, 20, 22 auf, welche an einem Grundkörper 24 des Spiegelmoduls 16 angeordnet sind. Wie zu erkennen, sind die drei unterschiedlichen Spiegel 18, 20, 22 an jeweils unterschiedlichen Seiten des Grundkör- pers 24 angeordnet. Das Spiegelmodul 16 ist dabei um eine Drehachse 26 in der mit dem Pfeil 28 gekennzeichneten Drehrichtung verdrehbar beziehungsweise verschwenkbar ausgebildet. Die Spiegel 18, 20, 22 können dabei sowohl konkav also auch konvex ausgebildet sein. Die bildgebende Einheit 12 ist dazu ausgebildet, einen Strahlengang 30 auszusenden. Der Faltspiegel 14 und das Spiegelmodul 16 bilden dabei ein optisches System aus, mittels welchem der Strahlengang 30 künstlich verlängert wird. Vorliegend ist der Spiegel 18 derart angeordnet, dass dieser in den Strahlengang 30 bewegt ist. Der Spiegel 18 fungiert als Asphärenspiegel, welcher auch als Konkavspiegel bezeichnet wird, und dient dazu, die Lichtstrahlen des Strahlengangs 30 zu parallelisieren, eine virtuelle Abbildung 32 zu vergrößern und Verzerrungen auszugleichen, die durch die Krümmung einer Windschutzscheibe 34 entstehen. Mit dem Faltspiegel 14 wird der Strahlengang 30 gefaltet. Durch diese Maßnahmen wird erreicht, dass das virtuelle Bild 32 in einem vorgegebenen Abstand, beispielsweise von zwei Metern Entfernung von einem Betrachter 36, üblicherweise dem Fahrer, knapp über einer Motorhaube eines Kraftwagens sichtbar wird. Unterschiedliche Kraftwagen weisen üblicherweise auch fahrzeugspezifische Windschutzscheibenvarianten auf. Die unterschiedlichen Spiegel 18, 20, 22 weisen dabei jeweils unterschiedliche Krümmungen auf, die an jeweilige fahrzeugspezifische Krümmungen jeweiliger Windschutzscheibenvarianten angepasst sind. Darüber hinaus können die Krümmungen der unterschiedli- chen Spiegel 18, 20, 22 auch an jeweilige fahrzeugspezifische Herstelltoleranzen der unterschiedlichen Windschutzscheibenvarianten angepasst sein. A total designated 10 head-up display is shown in a schematic representation in the single figure. The head-up display 10 comprises an imaging unit 12, a folding mirror 14 and a mirror module 16. The mirror module 16 in the present case has three differently curved mirrors 18, 20, 22, which are arranged on a base body 24 of the mirror module 16. As can be seen, the three different mirrors 18, 20, 22 are arranged on respectively different sides of the base body 24. The mirror module 16 is designed to be rotatable or pivotable about a rotation axis 26 in the direction of rotation indicated by the arrow 28. The mirrors 18, 20, 22 can be concave as well as convex. The imaging unit 12 is designed to emit a beam path 30. The folding mirror 14 and the mirror module 16 form an optical system by means of which the beam path 30 is artificially extended. In the present case, the mirror 18 is arranged such that it is moved into the beam path 30. The mirror 18 functions as an aspheric mirror, which is also referred to as a concave mirror, and serves to parallelize the light rays of the beam path 30, to enlarge a virtual image 32 and to compensate for distortions caused by the curvature of a windshield 34. With the folding mirror 14 of the beam path 30 is folded. Through these measures is achieved that the virtual image 32 is visible at a predetermined distance, for example, from two meters away from a viewer 36, usually the driver, just above a hood of a motor vehicle. Different cars usually also have vehicle-specific windshield variants. The different mirrors 18, 20, 22 each have different curvatures, which are adapted to respective vehicle-specific curvatures of respective windshield variants. In addition, the curvatures of the different mirrors 18, 20, 22 can also be adapted to respective vehicle-specific manufacturing tolerances of the different windshield variants.
Bei einem Einbau des Head-up-Displays 10 müssen somit keinerlei Komponenten ausgetauscht werden, um eine Anpassung an unterschiedliche Wind- schutzscheibenvarianten zu erzielen. Stattdessen wird während des Einbaus des Head-up-Displays 10 lediglich der passende Spiegel 18, 20 oder 22 ausgewählt, dessen Krümmung auf die jeweils fahrzeugspezifisch ausgebildete Windschutzscheibenvariante des Kraftwagens angepasst ist, in welchem das Head-up-Display 10 angeordnet werden soll. Das Spiegelmodul 16 muss nach dessen Anordnung innerhalb des Kraftwagens lediglich noch um die Achse 26 derart verdreht werden, dass der für die Windschutzscheibenvariante beziehungsweise die Fahrzeugvariante passende Spiegel 18, 20, 22 in dem Strahlengang 30 angeordnet wird. Das Spiegelmodul 16 kann darüber hinaus derart translatorisch bewegbar ausgebildet sein, dass zum Verändern einer virtuellen Bilddistanz 38 ein Abstand 40 in Richtung des Strahlengangs 30 zwischen dem Faltspiegel 14 und dem gerade als Asphärenspiegel dienenden Spiegel 18, 20, 22 des Spiegelmoduls 16 veränderbar ist. Das Head-up-Display 10 kann darüber hinaus einen Aktuator aufweisen, mittels welchem das Spiegelmodul 16 zum einen um die Drehachse 26 verdrehbar und zusätzlich in der vorstehend erläuterten Weise translatorisch bewegbar ist. Darüber hinaus kann das Head-up- Display 10 auch eine Bedieneinrichtung aufweisen, durch deren Betätigung der Aktuator zum Bewegen des Spiegelmoduls 16, also zum einen zum Verschwenken und zum anderen zum translatorischen Bewegen, ansteuerbar ist. When installing the head-up display 10, therefore, no components have to be exchanged in order to achieve an adaptation to different types of windshields. Instead, during installation of the head-up display 10, only the matching mirror 18, 20 or 22 is selected, whose curvature is adapted to the respectively vehicle-specific designed windshield variant of the motor vehicle, in which the head-up display 10 is to be arranged. The mirror module 16, after its arrangement within the motor vehicle, only needs to be rotated about the axis 26 in such a way that the mirror 18, 20, 22 that fits the windshield variant or the vehicle variant is arranged in the beam path 30. In addition, the mirror module 16 can be designed such that it can be moved in a translational manner such that a distance 40 in the direction of the beam path 30 between the folding mirror 14 and the mirror 18, 20, 22 of the mirror module 16 which is currently serving as the aspherical mirror can be varied to change a virtual image distance 38. The head-up display 10 may moreover comprise an actuator, by means of which the mirror module 16 is rotatable about the rotation axis 26 and additionally translationally movable in the manner explained above. In addition, the head-up display 10 may also have an operating device, by the actuation of which the actuator for moving the mirror module 16, that is, on the one hand for pivoting and the other for the translational movement, can be controlled.
Eine derartige Bedieneinrichtung kann beispielsweise im Fahrzeuginnenraum eines Kraftwagens angeordnet sein, sodass zum Beispiel ein Fahrer durch Betätigung der Bedieneinrichtung den Aktuator ansteuern kann, sodass dieser wiederum das Spiegelmodul 16 translatorisch bewegt, sodass die virtuelle Bilddistanz 38 wunschgemäß angepasst werden kann. Darüber hinaus kann eine derartige Bedieneinrichtung auch dazu dienen, während der Montage des Head-up-Displays 10 in einem Kraftwagen den passenden Spiegel 18, 20 oder 22 in den Bereich des Strahlengangs 30 zu verschwenken. Such an operating device can be arranged for example in the vehicle interior of a motor vehicle, so that, for example, a driver can actuate the actuator by actuation of the operating device, so that the latter in turn moves the mirror module 16 translationally, so that the virtual image distance 38 can be adjusted as desired. In addition, such an operating device can also serve to pivot the matching mirror 18, 20 or 22 into the region of the beam path 30 during assembly of the head-up display 10 in a motor vehicle.
In den bislang erläuterten Ausführungsbeispielen dienten die unterschiedli- chen Spiegel 18, 20, 22 also als Asphärenspiegel. Stattdessen ist es aber auch möglich, dass das Spiegelmodul 16 anstelle des Faltspiegels 14 angeordnet wird und als Asphärenspiegel ein einziger Spiegel verwendet wird. Die Anpassung an unterschiedliche Windschutzscheibenvarianten geschieht dabei in analoger Weise wie zuvor erläutert, wobei lediglich anstelle des starr angeordneten Faltspiegels 14 nun das Spiegelmodul 16 jeweils derart bewegt werden kann, dass der passende Spiegel 18, 20 oder 22 windschutz- scheibenvariantenspezifisch ausgewählt und positioniert wird. In the exemplary embodiments explained so far, the different mirrors 18, 20, 22 thus served as aspheric mirrors. Instead, it is also possible that the mirror module 16 is arranged in place of the folding mirror 14 and a single mirror is used as the aspheric mirror. The adaptation to different windshield variants is done in an analogous manner as explained above, only now instead of the rigidly arranged folding mirror 14, the mirror module 16 can each be moved so that the matching mirror 18, 20 or 22 windshield variant specifically selected and positioned.
Die unterschiedlichen Spiegel 18, 20, 22 können - unabhängig davon, ob das Spiegelmodul 16 an der Position des Faltspiegels oder des Asphärenspiegels angeordnet ist - auch austauschbar ausgebildet sein, sodass weitere Spiegel mit unterschiedlichen Krümmungswinkeln je nach Kundenwunsch an dem Spiegelmodul 16 angebracht und gegen andere Spiegel ausgetauscht werden können. The different mirrors 18, 20, 22 can - regardless of whether the mirror module 16 is arranged at the position of the folding mirror or the aspheric mirror - also be designed interchangeable, so that more mirrors with different angles of curvature depending on the customer attached to the mirror module 16 and against others Mirror can be exchanged.
