Description

Die Erfindung betrifft eine Vorrichtung für Fahrzeuge zur Überwachung des hinter dem Fahrzeug liegenden Raumes.The invention relates to a device for vehicles Monitoring of the area behind the vehicle.

Bislang sind zur Überwachung des hinter einem Fahrzeug liegen­ den Fahrbahnabschnitts Rückspiegel im Fahrgastraum und/oder am Äußern des Fahrzeugs vorgesehen. Eine vollständige und ver­ zerrungsfreie Beobachtung des rückwärtigen Verkehrs ist mit Spiegeln jedoch nicht möglich. Bei Verwendung von asphärischen Spiegeln kann stets ein kleiner Winkelbereich, ein sogenannter toter Winkel nicht eingesehen werden. Ein überholendes Fahrzeug, das sich in diesem Winkelbereich befindet, kann nicht wahrgenommen werden. Außenspiegel mit sphärischem Spiegelglas vermeiden diesen Nachteil, doch ergibt sich mit solchen Spie­ geln nur ein verzerrtes Abbild der hinter dem Fahrzeug liegen­ den Fahrbahn, wodurch die Einschätzung der Geschwindigkeit eines von hinten herannahenden Fahrzeugs erschwert wird. Außerdem haben Spiegel den Nachteil, daß bei Nacht eine Blendgefahr für den Fahrer durch die Scheinwerfer nachfolgen­ der Fahrzeuge gegeben ist. Eine Abblendmöglichkeit besteht in der Regel nur für den Innenspiegel. Bei häufig wechselnden Fahrern unterschiedlicher Körpergröße müssen zudem die Spiegel am Fahrzeug jedesmal neu justiert werden.So far are used to monitor the behind a vehicle the road section rear view mirror in the passenger compartment and / or on Exterior of the vehicle provided. A complete and ver distortion-free observation of the rear traffic is included However, mirroring is not possible. When using aspherical A small angular range, so-called, can always mirror blind spot cannot be seen. An overtaking vehicle that is in this angular range cannot be perceived. Outside mirror with spherical mirror glass  avoid this disadvantage, but with such game results only a distorted image behind the vehicle the roadway, making the assessment of the speed a vehicle approaching from behind is difficult. In addition, mirrors have the disadvantage that one at night Follow the risk of glare for the driver from the headlights of vehicles is given. A dimming option is in usually only for the inside mirror. With frequently changing Drivers of different heights also need the mirrors readjusted each time on the vehicle.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Überwa­ chung des rückwärtigen Verkehrs unter Vermeidung der oben genannten Nachteile zu ermöglichen.The invention is therefore based on the object back traffic avoiding the above to enable disadvantages mentioned.

Die gestellte Aufgabe wird mit einer Vorrichtung der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß sie min­ destens eine optische Aufnahmeeinrichtung und eine mit dieser verbundene optische Anzeigeeinrichtung im Fahrgastraum auf­ weist. Anzeigeeinrichtungen, wie beispielsweise Flüssig­ kristall-Displays, sollen bald zur Standardausrüstung jedes Kraftfahrzeugs gehören. Sie sollen als Anzeigemedium unter anderem für sogenannte Verkehrsleitsysteme eingesetzt werden, die eine Orientierungshilfe für den jeweils günstigsten Weg zu einem gewünschten Zielort sowie Stauinformationen und Umlei­ tungsempfehlungen bieten. Diese Displays können vorteilhaf­ terweise in der übrigen Zeit zur Überwachung des rückwärtigen Verkehrs genutzt werden, indem die von einer optischen Aufnah­ meeinrichtung aufgenommenen Bilder wiedergegeben werden. Ein solcher Einsatz der Monitore ist alternativ oder auch zusätz­ lich zu Rückspiegeln möglich. Dabei kann zweckmäßigerweise die optische Aufnahmeeinrichtung über eine Einrichtung zur Bild­ verarbeitung mit der Anzeigeeinrichtung verbunden sein. Mit der Einrichtung zur Bildverarbeitung ist beispielsweise eine Analog/Digital-Wandlung des Bildsignals sowie eine Vorverar­ beitung, beispielsweise eine Verstärkung oder Kontrastver­ schärfung durchführbar. Weitere Vorteile ergeben sich, wenn mindestens zwei Aufnahmevorrichtungen vorgesehen sind, deren Einzelbilder von der Einrichtung zur Bildverarbeitung zu einem Gesamtbild zusammengesetzt werden, das den gesamten rückwärti­ gen Raum abdeckt. Auf diese Weise ist eine verzerrungsfreie und vollständige Erfassung des hinter dem Fahrzeug liegenden Raumes möglich. Um einen Einsatz der Vorrichtung bei unter­ schiedlichen Lichtverhältnissen zu ermöglichen, kann die Lichtempfindlichkeit der mindestens einen Aufnahmeeinrichtung zweckmäßigerweise automatisch regulierbar sein. Zusammen mit einer entsprechenden Auswertung des aufgenommenen Bildsignals durch die Einrichtung zur Bildverarbeitung kann damit gewähr­ leistet werden, daß eine Überwachung des rückwärtigen Verkehrs auch bei Nacht und bei von hinten auf das Fahrzeug einfallen­ dem Sonnenlicht möglich ist. Eine Blendgefahr, wie sie bei Rückspiegeln auftritt, ist hierbei ausgeschlossen. Durch eine verstellbare Anordnung der mindestens einen Aufnahmevorrich­ tung am Fahrzeug, die beispielsweise eine Video-Kamera oder eine CCD-Kamera sein kann, ist eine schnelle Veränderung des beobachteten Fahrbahnausschnitts möglich. Eine Anpassung der Einstellung der mindestens einen Aufnahmevorrichtung an Fahrer unterschiedlicher Größe ist im Gegensatz zu Spiegeln jedoch nicht notwendig. Auch die Anzeigeeinrichtung kann im Fahrgast­ raum so angeordnet werden, daß sie vom Fahrersitz aus für sämtliche Personen ohne vorheriges Verstellen gut einsehbar ist. Die gesamte Vorrichtung kann zudem zweckmäßigerweise an die Stromversorgung des Kraftfahrzeugs angeschlossen sein.The task is accomplished with a device of the beginning mentioned type according to the invention in that they min at least one optical recording device and one with it connected optical display device in the passenger compartment points. Display devices such as liquid crystal displays will soon become standard equipment for everyone Motor vehicle belong. They are intended as a display medium under others are used for so-called traffic control systems, which provide guidance for the cheapest route a desired destination as well as traffic jam information and diversion offer recommendations. These displays can be advantageous usually in the remaining time to monitor the rear  Traffic can be used by optically recording recorded images can be played back. A such use of the monitors is alternative or additional possible with rear-view mirrors. In this case, the optical recording device via a device for image processing connected to the display device. With the device for image processing is, for example Analog / digital conversion of the image signal and a preprocess processing, such as amplification or contrast processing sharpening feasible. Other benefits arise when at least two receiving devices are provided, the Single images from the image processing device to one Overall picture can be composed, which the entire backward covering the room. This way is a distortion-free and complete detection of what is behind the vehicle Possible. To use the device at under to enable different lighting conditions Photosensitivity of the at least one recording device expediently be automatically adjustable. Along with a corresponding evaluation of the recorded image signal through the facility for image processing can thus guarantee be done to monitor the rear traffic also hit the vehicle at night and from behind sunlight is possible. A risk of glare, as in Rear-view mirroring is excluded. By a adjustable arrangement of the at least one receiving device device on the vehicle, for example a video camera or  a CCD camera can be a quick change of the observed road section possible. An adaptation of the Adjustment of the at least one pick-up device to the driver is different in size, however, in contrast to mirrors unnecessary. The display device can also be in the passenger be arranged so that they from the driver's seat for all people are clearly visible without prior adjustment is. The entire device can also expediently the power supply of the motor vehicle must be connected.

Nachfolgend wird ein bevorzugtes Ausführungsbeispiel einer erfindungsgemäßen Vorrichtung anhand der Zeichnung näher er­ läutert.Below is a preferred embodiment of one he device according to the invention with reference to the drawing purifies.

Die einzige Figur zeigt ein Blockschaltbild einer erfindungs­ gemäßen Vorrichtung. Im dargestellten Beispiel sind zwei Kame­ ras 10 und 11 als optische Aufnahmeeinrichtungen vorgesehen, die zweckmäßigerweise so am Fahrzeug angeordnet sind, daß mit ihnen die Beobachtung eines Winkelbereichs von 180° oder mehr und damit des gesamten hinter dem Fahrzeug liegenden Raumes möglich ist. Die Kameras 10 und 11 geben ihre Signale auf eine Einrichtung 12 zur Bildverarbeitung, die beispielsweise einen Analog/Digital-Wandler enthalten kann und die die Einzelbilder der Kameras 10 und 11 auswertet und zu einem Gesamtbild zu­ sammensetzt, das auf einem nachfolgenden Monitor 13 angezeigt wird. Das Gesamtbild kann dabei in Form von Helligkeits- und Farbwerten von einzelnen Bildpunkten vorliegen, mit denen die Flüssigkristallzellen des zweckmäßigerweise als flaches Flüs­ sigkristall-Display ausgebildeten Monitors angesteuert werden. Die Einrichtung 12 zur Bildverarbeitung kann auch ein Mikro­ prozessor aufweisen und frei programmierbar sein. Oder sie ist integrierter Bestandteil eines Bordcomputers, mit dem weitere Überwachungsfunktionen am Fahrzeug vorgenommen werden und in dem auch Programme von Verkehrsleitsystemen gespeichert sein können. Der Monitor 13 kann dann für sämtliche Überwachungsaufgaben sowie für das Verkehrsleitsystem als gemeinsames Anzeigemedium dienen. Den Hauptteil der Zeit wird der Monitor 13 zur Überwachung des rückwärtigen Verkehrs eingesetzt und bei Bedarf auf die Anzeige eines Programms des Verkehrsleit­ systems umgeschaltet bzw. zur gleichzeitigen Anzeige beider Funktionen in verschiedene Fenster aufgeteilt. Alarmsignale oder dergleichen können einfach in das Bild der hinter dem Fahrzeug liegenden Fahrbahn mit eingeblendet werden.The single figure shows a block diagram of an inventive device. In the example shown, two cameras 10 and 11 are provided as optical recording devices, which are expediently arranged on the vehicle in such a way that the observation of an angular range of 180 ° or more and thus the entire space behind the vehicle is possible. The cameras 10 and 11 transmit their signals to a device 12 for image processing, which can contain, for example, an analog / digital converter and which evaluates the individual images of the cameras 10 and 11 and composes them into an overall image which is displayed on a subsequent monitor 13 . The overall image can be in the form of brightness and color values of individual pixels with which the liquid crystal cells of the monitor, which is expediently designed as a flat liquid crystal display, can be controlled. The device 12 for image processing can also have a microprocessor and be freely programmable. Or it is an integral part of an on-board computer with which further monitoring functions can be carried out on the vehicle and in which programs from traffic management systems can also be stored. The monitor 13 can then serve as a common display medium for all monitoring tasks and for the traffic control system. The main part of the time, the monitor 13 is used to monitor the rear traffic and, if necessary, to switch to the display of a program of the traffic control system or to simultaneously display both functions in different windows. Alarm signals or the like can simply be superimposed on the image of the road behind the vehicle.

Die Kameras 10 und 11 sind außerdem mit Lichtsensoren 14 und 15 versehen, die eine automatische Regulierung der Lichtemp­ findlichkeit der Kameras 10 und 11 ermöglichen. Die Sensoren können außerdem mit der Einrichtung 12 zur Bildverarbeitung gekoppelt sein, so daß starke Über- oder Unterbelichtungen bei der späteren Verarbeitung der Bildsignale beispielsweise durch Kontrastverstärkung ausgeglichen werden können.The cameras 10 and 11 are also provided with light sensors 14 and 15 , which enable automatic regulation of the light sensitivity of the cameras 10 and 11 . The sensors can also be coupled to the device 12 for image processing, so that strong overexposure or underexposure can be compensated for during later processing of the image signals, for example by contrast enhancement.
