Description

'Innenrückspiegel' 'Rear view mirror'
Die Erfindung betrifft einen Innenrückspiegel zur Anordnung im Innenraum eines Kraftfahrzeugs mit einem Spiegelelement zur Beobachtung des nachfolgenden Verkehrs.The invention relates to an interior rearview mirror for arrangement in the interior of a motor vehicle with a mirror element for observation of the subsequent traffic.
Innenrückspiegel entsprechend der Gattung erfüllen bislang lediglich eine Aufgabe, nämlich die Möglichkeit der Beobachtung des rückwärti- gen Verkehrs. Dabei sind die Innenrückspiegel unmittelbar an der Windschutzscheibe oder am Himmel des Kraftfahrzeugs befestigt und über eine Automatik oder manuell abblendbar.Internal rearview mirrors according to the genre fulfill only one task so far, namely the possibility of observing the rearward traffic. The interior rearview mirrors are attached directly to the windscreen or in the sky of the motor vehicle and can be dimmed manually or automatically.
Bedingt durch die günstige Lage im Kraftfahrzeug und dem oftmaligen Kontrollblick von Seiten des Fahrzeugführers während der Fahrt, eignet sich der Innenrückspiegel jedoch nicht nur für die Beobachtung des nachfolgenden Verkehrs, sondern könnte darüber hinaus auch für die Darstellung weiterer wichtiger Informationen hilfreich sein.Due to the convenient location in the vehicle and the frequent inspection of the side of the driver while driving, the interior rear-view mirror is not only suitable for the observation of subsequent traffic, but could also be useful for the presentation of other important information.
Aus diesem Grunde ist es Aufgabe der vorliegenden Erfindung einen Innenrückspiegel zu schaffen, der neben der Beobachtung des nachfol- genden Verkehrs ein weiteres, der Fahrzeugsicherheit dienendes Funktionsmerkmal umfasst.For this reason, it is an object of the present invention to provide an interior rearview mirror, in addition to the observation of the following traffic includes another feature that serves vehicle safety.
Diese Aufgabe wird durch einen Innenrückspiegel nach der Lehre des Anspruchs 1 gelöst.This object is achieved by an interior rearview mirror according to the teaching of claim 1.
Vorteilhafte Ausführungsformen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Erfindungsgemäß ist der Innenrückspiegel dadurch gekennzeichnet, dass am Innenrückspiegel eine Projektionseinrichtung vorgesehen ist, mit der ein Lichtsignal auf eine Projektionsfläche am Fahrzeug projiziert werden kann. Die Anordnung der Projektionseinrichtung im oder am Innenrückspiegel hat den Vorteil, dass die Projektionseinrichtung nahezu resistent gegenüber Verschmutzungen und Vereisungen ausgeführt ist. Darüber hinaus unterliegt die Projektionseinrichtung einer geringeren Sonneneinstrahlungsbeeinflussung, wodurch eine bessere Wahrnehmung des Licht- Signals für den Kraftfahrzeugführer ermöglicht wird.According to the interior rearview mirror is characterized in that a projection device is provided on the interior rearview mirror, with which a light signal can be projected onto a projection surface on the vehicle. The arrangement of the projection device in or on the interior rearview mirror has the advantage that the projection device is made almost resistant to contamination and icing. In addition, the projection device is subject to a lower solar radiation influence, whereby a better perception of the light signal for the motor vehicle driver is made possible.
Eine Aus führungs form sieht vor, die Proj ektionseinrichtung in der Art einer Laserlichtquelle auszubilden. Das im Innenrückspiegel verbaute Lasermodul projiziert dann auf einer dem Fahrzeuglenker zugewandten Projektionsfläche eine optische Meldung, beispielsweise beim Fahrspur- Wechsel. Es ist natürlich auch denkbar Warnhinweise oder andere relevante Fahrzeuginformationen auf die Projektionsfläche zu projizieren.One embodiment provides for the development of the projection device in the manner of a laser light source. The laser module installed in the interior rearview mirror then projects an optical message on a projection surface facing the vehicle driver, for example when changing lanes. Of course, it is also conceivable to project warning notices or other relevant vehicle information onto the projection screen.
Eine weitere Ausführungsform der Erfindung sieht vor, dass als Projektionsfläche beispielsweise das Spiegelelement des Außenspiegels dienen kann. Dies hat den Vorteil, dass der Kraftfahrzeugführer das projizierte Signal während des Fahrspurwechsels leicht wahrnehmen kann, da der Blick des Kraftfahrzeugführers beim Fahrspurwechsel in der Regel verstärkt auf den Außenspiegel des Kraftfahrzeugs gerichtet ist.A further embodiment of the invention provides that, for example, the mirror element of the exterior mirror can serve as the projection surface. This has the advantage that the motor vehicle driver can easily perceive the projected signal during the lane change, since the driver's view of the lane change is usually increasingly directed to the outside mirror of the motor vehicle.
Es ist jedoch auch vorstellbar, dass als Proj ektionsfläche die Innenseite einer Seitenscheibe, insbesondere die Seitenscheibe der Fahrertür, dienen kann. Bevorzugt kann vorgesehen sein, dass die Projektionsfläche im Bereich des Sichtfeldes auf der Seitenscheibe angeordnet ist, durch das der Außenspiegel beobachtbar ist. Auch hierbei liegt der Vorteil darin, dass dieser Bereich der Seitenscheibe vom Kraftfahrzeugführer während des Fahrspurwechsels bzw. des Verkehrsflusses oft beobachtet und verstärkt wahrgenommen wird.However, it is also conceivable that the projection surface on the inside of a side window, in particular the side window of the driver's door, can serve. It can preferably be provided that the projection surface is arranged in the region of the field of view on the side window, through which the exterior mirror can be observed. Here, too, the advantage lies in the fact that this area of the side window is often observed and amplified by the motor vehicle driver during the lane change or the traffic flow.
Das Lichtsignal kann in der Art eines Warnsignals, insbesondere in der Art eines Warnsignals zur Warnung bei einem Spurwechsel, ausgebildet sein. Das Warnsignal kann also in der Art eines Spurverlassenswarners ausgebildet sein, welcher den Fahrer bei Verlassen der Fahrspur oder drohendem Verlassen der Fahrspur warnt. Dabei wird überprüft, ob das Fahrzeug die beispielsweise durch Fahrbahnrandmarkierung begrenzte Fahrspur verlässt bzw. zu verlassen droht. Ist dies der Fall, wird der Fahrer gewarnt. Denkbar ist ferner das Warnsignal zusätzlich beispiels- weise akustisch zu Untermauern, um so die volle Aufmerksamkeit des Fahrzeugführers zu gewährleisten.The light signal may be in the form of a warning signal, in particular in the form of a warning signal for warning in the event of a lane change. The warning signal can therefore be designed in the manner of a lane departure warning system, which warns the driver when leaving the lane or threatening to leave the lane. In this case, it is checked whether the vehicle leaves or threatens to leave the lane, which is limited, for example, by lane markings. If this is the case, the driver is warned. In addition, the warning signal is additionally acoustically underpinned, for example, in order to ensure the full attention of the vehicle driver.
Eine bevorzugte Ausführungsform der Erfindung sieht ferner vor, dass als Projektionsfläche die Oberseite des Armaturenbretts dienen kann. Dies hat den Vorteil, dass die Projektionsfläche verstärkt gegenüber möglichen Sonneneinstrahlungsbeeinflussungen geschützt werden kann und ebenfalls resistent gegenüber Vereisungen oder dergleichen ausgebildet ist. Als Projektionsfläche kann dabei die ursprüngliche Oberseite des Armaturenbretts dienen bzw. eine auf der Oberseite des Armaturenbretts befestigbare externe Projektionsfläche, welche beispielsweise in der Art einer Tafel oder dergleichen, ausgebildet sein kann.A preferred embodiment of the invention also provides that the top of the dashboard can serve as a projection surface. This has the advantage that the projection surface can be protected against possible solar radiation influences and is also resistant to icing or the like. In this case, the original upper side of the dashboard can serve as a projection surface or an external projection surface which can be fastened on the upper side of the dashboard and which can be designed, for example, in the manner of a panel or the like.
Eine weitere bevorzugte Ausführungsform der Erfindung sieht vor, dass das Lichtsignal in der Art einer Tastatur, eines Tastaturelements oder in der Art eines Bedienelements ausgebildet sein kann. Beispielsweise ist denkbar, das Lichtsignal mit Bedien- oder Tastenelementen zu verknüp- fen, so dass Funktionen bzw. Funktionsmerkmale in Abhängigkeit des ausgegebenen Lichtsignals generiert werden können. Denkbar ist ferner, dass die Bedienung bzw. Wahrnehmung der Tastatur- bzw. Bedienelemente durch geeignete Mittel zusätzlich haptisch, optisch oder akustisch verstärkt oder unterstützt werden kann.A further preferred embodiment of the invention provides that the light signal can be designed in the manner of a keyboard, a keyboard element or in the manner of a control element. For example, it is conceivable to link the light signal with operating or key elements, so that functions or functional features can be generated as a function of the output light signal. It is also conceivable that the operation or perception of the keyboard or operating elements can be additionally reinforced or supported haptically, optically or acoustically by suitable means.
Eine besonders bevorzugte Aus führungs form der Erfindung sieht vor, dass die Projektionseinrichtung hinter einer Lichtaustrittsöffnung im Gehäuse des Innenrückspiegels angeordnet sein kann. Dabei ist die Lichtaustrittsöffnung bevorzugt auf der vom Auge des Fahrers abgewandten Seite des Gehäuses angeordnet. Für den Fahrer des Kraftfahrzeugs entsteht somit keine unangenehme Blendwirkung bzw. störendes Lichtaustrittssignal, da die Lichtaustrittsöffnung vom Fahrer des Kraftfahrzeugs nicht wahrgenommen wird.A particularly preferred embodiment of the invention provides that the projection device can be arranged behind a light exit opening in the housing of the interior rearview mirror. In this case, the light exit opening is preferably arranged on the side facing away from the driver's eye side of the housing. For the driver of the motor vehicle thus creates no unpleasant glare or disturbing light exit signal, since the light exit opening is not perceived by the driver of the motor vehicle.
Nachfolgend wird die Erfindung anhand schematischer Zeichnungen beispielhaft erläutert.The invention will be explained by way of example with reference to schematic drawings.

In Fig. 1 ist eine erste Ausführungsform eines Innenrückspiegels 01 mit einer darin angeordneten Projektionseinrichtung 02, mit der eine Information 03 auf eine Projektionsfläche 04 am Fahrzeug projiziert werden kann, dargestellt. Die Projektionsfläche 04 wird hierbei vom Spiegelele- ment 05 des Außenspiegels 06 des Kraftfahrzeugs gebildet. Die Proj ektionseinrichtung 02 ist in der Art einer Laserlichtquelle ausgebildet und projiziert einen Laserlichtstrahl bzw. ein Lichtsignal 07, welches in der Art eines Warnsignals, hierbei insbesondere in der Art eines Warnsignals zur Warnung bei einem Spurwechsel ausgebildet ist, auf die Projektions- fläche 04. Die Projektionseinrichtung 02 ist so in den Innenrückspiegel 01 integriert, dass für den Fahrer des Kraftfahrzeugs lediglich eine Projektionsöffnung bzw. ein Projektionsglas oder dergleichen, wahrnehmbar ist. Es ist auch denkbar die Projektionseinrichtung nachträglich beispielsweise als externes Bauteil am Innenrückspiegel anzubringen. Dies hätte den Vorteil, dass ältere Innenrückspiegel nachträglich mit einer Projektionseinrichtung versehen werden könnten.1 shows a first embodiment of an interior rearview mirror 01 with a projection device 02 arranged therein, with which information 03 can be projected onto a projection surface 04 on the vehicle. In this case, the projection surface 04 is formed by the mirror element 05 of the exterior mirror 06 of the motor vehicle. The proj ektionseinrichtung 02 is formed in the manner of a laser light source and projects a laser light beam or a light signal 07 which is formed in the manner of a warning signal, in this case in particular in the manner of a warning signal for warning in a lane change, on the projection Surface 04. The projection device 02 is integrated into the interior rearview mirror 01 such that only a projection opening or a projection glass or the like is perceptible to the driver of the motor vehicle. It is also conceivable to attach the projection device subsequently, for example as an external component on the interior rearview mirror. This would have the advantage that older interior rearview mirrors could be retrofitted with a projection device.
Das Lichtsignal 07 wird unbemerkt vom Kraftfahrzeugführer auf die Projektionsfläche 04 projiziert und kann dem Kraftfahrzeugführer, j e nach gewünschtem Funktionsumfang, Informationen aus dem Innenraum des Kraftfahrzeugs oder Informationen den umgebenden Verkehr des Kraftfahrzeugs betreffend zur Verfügung stellen.The light signal 07 is unnoticed projected by the motor vehicle driver onto the projection surface 04 and can provide the motor vehicle driver, j e according to the desired range of functions, information from the interior of the vehicle or information about the surrounding traffic of the motor vehicle available.
In Fig. 2 ist eine zweite Ausführungsform eines Innenrückspiegels 08 mit einer im Innenrückspiegel angeordneten Projektionseinrichtung 09 dargestellt. Die Proj ektionseinrichtung 09 projiziert ein Lichtsignal 10 auf eine Projektionsfläche 1 1 , wobei die Projektionsfläche 1 1 eine Oberseite des Armaturenbretts 12 darstellt. Das Lichtsignal 10 projiziert das Lichtsignal auf eine Tastatur 13 bzw. auf Tastaturelemente 14, so dass beispielsweise in Abhängigkeit des ausgegebenen Lichtsignals 10 das betreffende Tastaturelement der Tastatur 13 gewählt bzw. betätigt werden kann. Je nach Bedarf können über das Lichtsignal 10 verschiedene Tastaturelemente der Tastatur 13 mit verschiedenen Symbolen bzw. Warnhinweisen belegt und so mit der Tastatur 13 verknüpft werden. Denkbar ist ferner, die Wahrnehmung bzw. Bedienung der Tastatur- bzw. Bedienelemente mit geeigneten Mitteln, beispielsweise akustisch oder haptisch, zu verstärken bzw. zu untermalen. Beispielsweise wäre im Falle einer bevorstehenden Projizierung denkbar, dem Fahrer ein akustisches Signal zu übermitteln, mit dem die Aufmerksamkeit des Fahrers auf die Proj ektionsfläche 1 1 gelenkt werden kann. Kann der Fahrer den Blick nicht in Richtung der Projektionsfläche wenden, so wäre denkbar die Wahrnehmung der einzelnen Bedienelemente haptisch zu verstärken. FIG. 2 shows a second embodiment of an interior rear-view mirror 08 with a projection device 09 arranged in the interior rear-view mirror. The projection device 09 projects a light signal 10 onto a projection surface 11, the projection surface 11 representing an upper side of the dashboard 12. The light signal 10 projects the light signal onto a keyboard 13 or keyboard elements 14 so that, for example, depending on the output light signal 10, the relevant keyboard element of the keyboard 13 can be selected or actuated. Depending on requirements, various keyboard elements of the keyboard 13 can be assigned different symbols or warnings via the light signal 10 and can thus be linked to the keyboard 13. It is also conceivable to amplify the perception or operation of the keyboard or operating elements by suitable means, for example acoustically or haptically. For example, in the case of imminent projecting, it would be conceivable to transmit to the driver an acoustic signal with which the driver's attention to the projecting surface 11 can be directed. If the driver can not look in the direction of the projection surface, it would be conceivable to haptically increase the perception of the individual control elements.
