Abstract

In a rear-view mirror for a motor vehicle there is provided a display surface (4) on which a barchart is able to indicate when a critical distance from an obstruction is not being observed. This causes the warning display to be directly visible during positioning. <IMAGE>

Description

Die Erfindung bezieht sich auf einen Rückspiegel für ein Kraftfahrzeug.The invention relates to a rear view mirror for a Motor vehicle.

Kraftfahrzeuge haben immer entweder zwei Außenspiegel oder einen Außenspiegel und einen Innenspiegel. Insbeson­ dere der Innenspiegel liegt im unmittelbaren Blickfeld des Fahrers. Der Außenspiegel wird vor allem von Last­ wagenfahrern beim Rückwärtsfahren benutzt, so daß er dann auch im Blickfeld liegt.Motor vehicles always have either two exterior mirrors or an outside mirror and an inside mirror. In particular the inside mirror is in the immediate field of vision of the driver. The wing mirror is mostly under load used when driving backwards, so that he then also in view.

Zur Erleichterung des Rangierens von Kraftfahrzeugen sind in jüngster Zeit Abstandswarneinrichtungen bekannt­ geworden, die durch ein akustisches oder optisches Sig­ nal den Fahrer warnen, wenn er sich einem Hindernis un­ erwünscht stark annähert. Die Warngeber solcher Abstands­ warneinrichtungen sind üblicherweise in der Armaturen­ tafel angeordnet. Da der Fahrer beim Rückwärtsfahren jedoch meist sorgfältig in den Spiegel sieht, kann eine optische Anzeige in der Armaturentafel leicht übersehen werden. Die akustische Warneinrichtung hat den Nachteil, daß sie nur einen Grenzwert zu signalisieren vermag.To facilitate maneuvering of motor vehicles Distance warning devices have been known in recent times become, which by an acoustic or optical Sig warn the driver if he encounters an obstacle desirable approximates strongly. The warning givers of such distance warning devices are usually in the fittings blackboard arranged. Because the driver when reversing however, one can usually look carefully in the mirror optical display in the dashboard easily overlooked will. The acoustic warning device has the disadvantage that it can only signal a limit value.

Der Erfindung liegt die Aufgabe zugrunde, einen Spiegel für ein Kraftfahrzeug zu entwickeln, mit dem eine unzu­ lässige Annäherung an ein Hindernis feststellbar ist.The invention has for its object a mirror to develop for a motor vehicle with which an unzu casual approach to an obstacle can be determined.

Diese Aufgabe wird erfindungsgemäß gelöst durch eine Anzeigefläche zur Visualisierung des Fahrzeugabstandes von einem Hindernis.This object is achieved by a Display area for visualizing the vehicle distance from an obstacle.

Durch diese Anzeigefläche im Rückspiegel vermag ein Fahrer das Annähern an ein Hindernis auf der Anzeige­ fläche zu erkennen, ohne seinen Blick vom Rückspiegel wenden zu müssen. Dadurch ist ein Übersehen der Abstands­ warnanzeige so gut wie ausgeschlossen. Da die Anzeige­ fläche im Rückspiegel angeordnet ist, kann ein Fahrzeug sehr kostengünstig bei nachträglicher Ausrüstung mit einer Abstandswarneinrichtung mit einer solchen Anzeige­ fläche versehen werden, indem lediglich der übliche Rück­ spiegel durch den erfindungsgemäßen Rückspiegel ersetzt wird.Through this display area in the rearview mirror is able to Driver approaching an obstacle on the display recognizable surface without looking from the rearview mirror to have to turn. This is an overlook of the distance warning display almost impossible. Because the ad is arranged in the rearview mirror, a vehicle very inexpensive with retrofitting a distance warning device with such a display be provided by just the usual back mirror replaced by the rear-view mirror according to the invention becomes.

Besonders kostengünstig ist der Rückspiegel gestaltet, wenn die Anzeigefläche ein Flüssigkristallfeld mit einem Bargraph ist. Ein solcher Bargraph verdeutlicht zudem sehr anschaulich den abnehmenden Abstand, wenn man auf ein Hindernis zu fährt.The rear-view mirror is particularly cost-effective, if the display surface is a liquid crystal panel with a Is bar graph. Such a bar graph also illustrates very descriptive of the decreasing distance when looking at to drive an obstacle.

Besonders gut zu erkennen ist die Anzeigefläche beim Rangieren durch Blick in den Rückspiegel, wenn die An­ zeigefläche im Spiegelgehäuse unmittelbar unterhalb der Spiegelfläche vorgesehen ist.The display area of the Maneuver by looking in the rear view mirror when the on display area in the mirror housing immediately below the Mirror surface is provided.

Das Unterschreiten eines zu geringen Abstandes, bei dem zum Beispiel ein anderes Fahrzeug nicht mehr aus seiner Parklücke heraus zu rangieren wäre, kann sehr anschau­ lich signalisiert werden, wenn die Anzeigefläche eine einen ungefährlichen Abstand anzeigenden Anzeigebereich und fluchtend dazu einen einen kritischen Abstand an­ zeigenden Anzeigebereich aufweist.If the distance is too short, the for example another vehicle no longer out of its It would be very good to rank parking spaces out Lich signaled when the display area a a non-dangerous distance display area and aligned to a critical distance  showing display area.

Die Erfindung läßt zahlreiche Ausführungsformen zu. Zur weiteren Verdeutlichung ihres Grundgedankens ist eine davon in der Zeichnung dargestellt und wird nachfolgend beschrieben.The invention allows numerous embodiments. To further clarification of their basic idea is one of which is shown in the drawing and is shown below described.

Die Zeichnung zeigt einen Rückspiegel 1, der in einem Spiegelgehäuse 2 eine Spiegelfläche 3 haltert. Unterhalb der Spiegelfläche 3 ist im Spiegelgehäuse 2 eine Anzeige­ fläche 4 vorgesehen, die von einem Bargraph gebildet ist. Die Anzeigefläche 4 ist unterteilt in einen ersten Bereich 5, in dem ungefährliche Abstände signalisiert werden, und einen zweiten Bereich 6 zur Signalisierung kritischer Abstände von einem Hindernis. Dieser zweite Bereich 6 ist fluchtend zum ersten Bereich 5 angeordnet, so daß der Bargraph beim Unterschreiten eines kritischen Abstandes in diesen zweiten Bereich hineinwandert.The drawing shows a rear-view mirror 1, which supports a mirror surface 3 in a mirror housing. 2 Below the mirror surface 3 is a display area 4 is provided in the mirror housing 2, which is formed by a bar graph. The display area 4 is divided into a first area 5 , in which safe distances are signaled, and a second area 6 for signaling critical distances from an obstacle. This second area 6 is arranged in alignment with the first area 5 , so that the bar graph moves into this second area when a critical distance is undershot.
