Description

Die Erfindung bezieht sich auf eine Vorrichtung mit den im Oberbegriff des Patentanspruchs 1 angegebenen Merkma len. The invention relates to drop on a device having the features specified in the preamble of claim 1 Merkma.

Derartige Vorrichtungen werden eingesetzt, um es insbe sondere dem Fahrer eines Kraftfahrzeugs zu ermöglichen, schwer einsehbare Bereiche der Fahrzeugumgebung wahrzu nehmen und so kritische Fahrsituationen zu vermeiden. Such devices are used to it sondere in particular to allow the driver of a motor vehicle, wahrzu take blind areas of the vehicle environment and to avoid critical driving situations.

Diese Bereiche, zu denen die Sicht verbessert werden soll, liegen vornehmlich im Heck- und im Frontbereich des Fahrzeugs. These areas, which include the vision is to be improved are, principally in the rear and in the front area of ​​the vehicle. Sehr nahe am Kraftfahrzeug sind sogenannte tote Bereiche, die von Hauben oder Säulen des Kraftfahr zeugs abgedeckt und damit nicht einsehbar sind. Very close to the vehicle are so-called dead zones that are zeugs covered by hoods or pillars of the motor vehicle and thus not visible. Beim Ein- und Ausparken kann dies problematisch sein. During parking maneuvers, this can be problematic. Gleichermaßen ist auch der mittels eines Rückspiegels einsehbare Be reich je nach Lage des Spiegels und Karosseriegestaltung eingeschränkt. Likewise, the viewable by means of a rearview mirror Be is rich regions depending on the location of the mirror and body design. Zusätzlich besteht die Möglichkeit, daß die Sicht aufgrund von schlechten Wetter- oder Klimaver hältnissen durch die Scheibe des Fahrzeugs eingeschränkt ist. In addition, there is the possibility that the viewing ratios due to bad weather or Klimaver is restricted by the window of the vehicle.

Zur Milderung der genannten Probleme sind verschiedene Lösungen entwickelt worden. To alleviate the above problems, various solutions have been developed. Es wurden Abstandssensoren insbesondere im Heckbereich von Fahrzeugen angeordnet, und auf Anzeigeelementen im Fahrzeug wird der Abstand zu im Nahbereich des Fahrzeugs befindlichen Gegenständen an gezeigt (Beispiel DE 37 35 847 A1), womit insbesondere Parkvorgänge erleichtert, jedoch nicht die Sicht verbes sert wird. There are arranged in particular at the rear of vehicles, distance sensors, and display elements in the vehicle, the distance to located in the vicinity of the vehicle objects to be shown (for example DE 37 35 847. A1), which in particular parking processes easier, but the view is not sert verbes. Nachteilig ist, daß keine detaillierte Infor mation darüber ausgegeben wird, welcher Abstand (also von welchem Ort des Fahrzeugs zu welchem Gegenstand in der Umgebung) angezeigt wird. The disadvantage is that no detailed infor mation is output as to which distance (that is, from which location of the vehicle to which the subject in the area) is displayed.

Andererseits existieren diverse Vorschläge zur Anordnung von Kameras am Fahrzeug (Bsp.: JP 3-99952 (A)-Abstract), die sensorisch Bildinformationen erfassen, welche nach einer elektronischen Verarbeitung auf einem Bildschirm im Fahrzeug angezeigt werden. On the other hand, various proposals exist for the arrangement of cameras on the vehicle (Ex .: JP 3-99952 (A) -abstract), detect the sensory image information, which are displayed according to an electronic processing on a screen in the vehicle. Die Kameras können an Orten des Fahrzeugs angebracht werden, von wo aus eine freie Sicht möglich ist, so daß also weder Karosserieelemente noch die Sicht störende Scheiben einen negativen Einfluß haben. The cameras can be mounted in places of the vehicle, from which is possible from a clear view, so that neither body elements nor the vision disturbing discs have a negative influence. Mit Hilfe der Kameras ist es auch möglich, die Fahrzeugumgebung bei schlechten Witterungsverhältnissen (Regen, Schnee, Neben, Dunkelheit...) unter Umständen besser wahrzunehmen, als dies das menschliche Auge vermag. With the help of cameras, it is also possible for the vehicle environment in poor weather conditions (rain, snow, side, darkness ...) better perceive circumstances than does the human eye.

Vorrichtungen der genannten Art dienen nicht nur der Ver besserung der Sicht, sondern können auch in automatische Fahrzeug-Steuervorgänge einbezogen werden. Devices of the type mentioned are not only used Ver improvement of vision but can control operations vehicle be involved in automatic. So können bei sich nähernden Hindernissen automatische Brems- oder Lenkmanöver eingeleitet werden. So automatic braking or steering maneuvers can be initiated at the approaching obstacles.

Aus der DE 27 27 303 A1 ist eine Vorrichtung mit Kamera und Bildschirm bekannt, womit die Sicht eines Fahrzeug führers nach hinten verbessert werden soll. From DE 27 27 303 A1 an apparatus with camera and the screen is known, with which the view of a vehicle to be improved leader backward. Auf eine elektronische Bildverarbeitung wurde verzichtet, jedoch sind spezielle optische Linsensysteme vorgesehen. An electronic image processing has been omitted, however, special optical lens systems are provided. Ver gleichbar, jedoch unter Nutzung mehrerer Bildaufnehmer und mehrerer Displays ist die Anordnung nach DE 32 48 511 A1. Ver parable, but using multiple imager and multiple displays, the arrangement according to DE 32 48 511 A1.

Eine gattungsgemäße Vorrichtung ist in dem Gebrauchsmu ster DE 29 61 2536 U1 beschrieben, wo zumindest eine Vi deokamera und ein Monitor im Fahrzeug vorgesehen sind. A generic device described in the Gebrauchsmu art DE 29 61 2536 U1, where Vi deokamera and a monitor are provided at least in the vehicle. Der Monitor ist vorzugsweise als Ersatz eines Innenrück spiegels angeordnet und es ist vorgesehen, variable Bild informationen darzustellen, was durch elektronische Bear beitung der aufgenommenen Bilder möglich ist. The monitor is preferably arranged as a spare interior rearview mirror and it is intended, variable image information display, which is by electronic Bear of the captured images processing possible. So können verschiedene Bildausschnitte einzeln oder gleichzeitig über den Monitor ausgegeben werden. So different compositions, individually or simultaneously output on the monitor.

Alle bislang vorgestellten Kamera-Monitor-Systeme in Kraftfahrzeugen haben den Mangel, daß nur begrenzt über sichtliche zweidimensionale Bilder dargestellt werden können. All previously featured camera-monitor systems in motor vehicles have a defect that can be displayed only limited clear two-dimensional images. Es besteht zwar der Vorteil, daß Bereiche einge sehen werden können, die dem Auge des Fahrzeugführers verborgen sind, aber die Übersichtlichkeit der Bildinfor mationen ist begrenzt. While there is the advantage that areas be can be seen, which are hidden from the eye of the driver, but mation the clarity of Bildinfor is limited. Dieses Problem wird bedeutender, wenn die Anzahl der Kameras am Fahrzeug gering sein soll, da dann jede Kamera einen relativ großen Raum einsehen muß. This problem becomes more significant when the number of cameras to be low on the vehicle, since then, each camera must see a relatively large space. Damit müssen optische Hilfsmittel (beispielsweise Weitwinkelobjektive) verwendet werden, die zu einer Ver zerrung des Bildes führen. Thus optical aids need (for example, wide-angle lenses) are used, the distortion to a United lead the image. Die Aufhebung der Verzerrung vor der Darstellung ist zwar durch aufwendige elektroni sche Bildverarbeitung möglich, jedoch fehlt auch dann die Übersichtlichkeit wegen der zweidimensionalen Darstel lung, welche keine Abstandsinformationen beinhaltet. The abolition of distortion before display is possible through sophisticated electronic specific image processing, but also the clarity is lacking development due to the two-dimensional depicting, which does not include distance information.

Ein weiterer Nachteil der bekannten Vorrichtungen ist, daß dem Fahrer ein relativ hoher Einstellaufwand überlas sen wird. A further disadvantage of the known devices is that the driver is read over a relatively high sen adjustment effort. Zur Anpassung des Bildes an die aktuelle Fahr situation hat der Fahrer beispielsweise die Kameraoptik oder den Anzeigemodus einzustellen, was ihn von der aktu ellen Verkehrslage ablenkt. situation to adapt the image to the current driving the driver, for example, adjust the camera lens or the display mode that distracts him from aktu economic traffic.

Es ist Aufgabe der Erfindung, eine Vorrichtung zur beson ders übersichtlichen bildlichen Darstellung von Bereichen der Fahrzeugumgebung zu schaffen, wobei der Aufwand für den Fahrer zur Bedienung der Vorrichtung minimiert werden soll. It is an object of the invention, an apparatus for particular DERS clear visual representation to create portions of the vehicle environment, wherein the cost is to be minimized for the driver to operate the device.

Zur Lösung dieser Aufgabe wurde eine gattungsgemäße Vor richtung nach den Merkmalen des kennzeichnenden Teils des An spruches 1 ausgebildet. To achieve this object a generic Before was direction according to the features of the characterizing portion of the award on formed. 1 Sie ist mit einer Steuereinheit ausgestattet, der neben den Bildinformationen auch Betriebskennwerte des Fahr zeugs zugeleitet werden. It is equipped with a control unit which, in addition to the image information and operating characteristics of the driving are zeugs fed. Die Steuereinheit ist derart ausgebildet, daß sie in Abhängigkeit der Betriebskennwer te die Art der bildlichen Darstellung im Fahrzeug ein stellt. The control unit is designed such that it in dependence of the type of Betriebskennwer te a pictorial representation in the vehicle provides. Es ist möglich, zwischen einer Darstellungsart "Draufsicht auf die Kraftfahrzeugumgebung", was einer Vo gelperspektive entspricht, und einer Darstellungsart "Realbild" umzuschalten. It is possible between a display type "top view of the automotive environment", which corresponds to a gelperspektive Vo, and to switch a display type "real image". Das "Realbild" ist die bekannte Art der Darstellung der Kameraperspektive, die keine Ab standsinformationen beinhaltet. The "real image" is the familiar way of representing the camera perspective that no Ab was information includes. Abstände können nur auf Basis von Erfahrungswerten geschätzt werden. Distances can be estimated on the basis of experience.

Neu und von besonderem Vorteil ist die Möglichkeit der betriebskennwertabhängigen Darstellung der "Draufsicht". New and of particular advantage is the possibility of operating characteristic value-based representation of the "Top View". Diese Art der Darstellung wird ermöglicht, wenn die Bild informationen, die sensorisch erfaßt werden, auch Infor mationen über die Raumlage von Elementen des aufgenom menen Bildes enthalten. This type of display is made possible if the image information, which are detected by sensors, also infor mation about the spatial position of elements of the image contained aufgenom menen. Es wird also zu jedem Punkt der Bildfläche ein Entfernungswert ermittelt, was mit Hilfe von intelligenter Sensorfusion möglich ist, wobei derartige Sensoren beispielsweise in DE 44 39 298 A1 und verfeinert in DE 197 04 496 A1 beschrieben sind. It is thus determined for each point of the image surface a distance value, which is possible with the help of intelligent sensor fusion, and such sensors are described for example in DE 44 39 298 A1 and refined in DE 197 04 496 A1.

Neben den beiden genannten Darstellungsarten kann die bildliche Darstellung der Fahrzeugumgebung bei Bestehen' bestimmter Betriebsparameter auch ganz abgebrochen werden (bei "Zündung Aus" oder wenn keine sinnvolle Darstellung möglich ist). Apart from these two types of representation, the visual representation of the vehicle environment in existence 'of certain operating parameters can also be completely canceled (with "ignition off" or if no meaningful representation is possible).

Als der Steuereinheit zu übermittelnde Betriebskennwerte sind vorzugsweise die Werte "Fahrzeuggeschwindigkeit" und/oder "eingelegter Gang" (am Schaltgetriebe einge stellte Schaltstufe) anzugeben. When the control unit to be transmitted operating characteristic values, the values ​​"vehicle speed" and / or "gear engaged" are preferably (turned on manual shift stage set) indicated.

Kameras zur sensorischen Erfassung der Bildinformationen können insbesondere am Heck und oder im Frontbereich des Kraftfahrzeugs angeordnet werden. Cameras for sensory detection of the image information can particularly at the stern and or in the front region of the motor vehicle are arranged. Im Fahrzeug wird ein oder auch mehrere Bildschirme angeordnet, wobei auch be reits für andere Zwecke (wie Navigationssystem) genutzte Bildschirme zur Bilddarstellung verwendet werden können. In the vehicle, one or more screens also is arranged, also be already for other purposes (such as a navigation system) can be used with screens used for image display. Von Vorteil ist die Anwendung eines Bildschirms als Er satz eines Innenrückspiegels, wie dies in DE 29 61 2536 U1 gezeigt ist. the application of advantage of a screen as he set an interior rear view mirror, as shown in DE 29 61 2536 U1. Auf diesem Bildschirm wird das Realbild dargestellt, welches von einer Kamera im Heckbereich auf genommen wird. On this screen, the real image is shown which is taken by a camera in the rear portion. Wird der Rückwärtsgang am Schaltgetriebe eingestellt, wird die Art der Bilddarstellung dort umge schaltet auf "Draufsicht" oder die "Draufsicht" wird auf einem weiteren Bildschirm zusätzlich dargestellt. When reverse gear set on the manual transmission, the type of image representation is converted there switches to "top view" or the "plan view" is also shown on another screen. Da bei Rückwärtsfahrt die Information eines Navigationssystems nicht notwendig ist, bietet sich dieser Bildschirm beson ders an. Since when reversing the information of a navigation system is not necessary, this screen provides special at id.

Die der Steuereinheit zugeleiteten Geschwindigkeitsdaten sind vorteilhaft nutzbar zur Festlegung des Darstellungs maßstabs auf dem Bildschirm. The supplied to the control unit speed data is advantageously used to determine the scale representation on the screen. Es sollte ein Darstellungs maßstab gewählt werden, der dem Fahrer auch die Möglich keit zur Reaktion beläßt. There should be a representation be selected to scale, of the possible leaves the driver ness to react. Von Vorteil ist die Darstellung eines Bereiches, der innerhalb von einer bis etwa zehn Sekunden erreichbar ist. Of advantage is the representation of a region which is accessible to about ten seconds within a.

Auf dem Bildschirm / den Bildschirmen können neben den genannten Bilddarstellungen zusätzlich auch weitere In formationen dargestellt werden. On the screen / screens can be displayed formations in addition to said image representations addition, other In. Diese sind neben den Bil dern oder in diese "eingemischt" darstellbar. These are countries in addition to the Bil or "mixed" in this presentable. So können Abstands-, Richtungs-, Geschwindigkeitsinformationen aus gegeben oder auch Vorschläge für Fahrmanöver angezeigt werden. Sun distance, direction, speed information can, if made or proposals are displayed for maneuver.

Kommt auch eine Kamera im Frontbereich des Fahrzeugs zum Einsatz, ist es ebenfalls sinnvoll, den Darstellungsmaß stab auf einem Bildschirm geschwindigkeitsabhängig einzu stellen. Is also a camera in front of the vehicle for use, it is also useful to Darstellungsmaß rod on a screen depending on the speed einzu filters. Um dem Fahrer eine schnelle Gewöhnung an das Sy stem zu ermöglichen, sollte der Maßstab gleichzeitig mit Gangwechselvorgängen gewechselt werden, so daß jedem Gang ein fester Maßstab zugeordnet ist. In order to allow the driver to quickly getting used to the Sy stem, the scale should be changed simultaneously with gear changes, so that each gear is associated with a fixed scale.

Bei guter Sicht ist die Darstellung des Frontkamera-Bil des weniger wichtig, was sich bei schlechten Sichtver hältnissen aber ändert. On a clear day the view of the front camera-Bil is of less importance, but what changes ratios in low clear line of sight. Wird bei Auswertung der dreidi mensionalen Bildinformationen eine Person oder ein Gegen stand im Fahrbereich des Fahrzeugs festgestellt, kann die Art der Bilddarstellung auch hier umgeschaltet werden von "Realbild" auf "Draufsicht", wobei dann exakte Abstands informationen ersichtlich sind. If, in evaluation of the dreidi dimensional image information a person or detected an object within the operating range of the vehicle, the type of image display are switched here of "real image" in "plan view", in which case precise distance information are shown. Je nach Kameraart und -optik ist es möglich, die erfaßten Objekte auf dem Bild schirm darzustellen, bevor sie für das menschliche Auge sichtbar sind. Depending on the type of camera and optics it is possible to represent the detected objects in the picture screen before they are visible to the human eye. Die Bildausgabe kann dann gekoppelt werden mit der Ausgabe von Warntönen oder mit einer Sprachausga be von Hinweisen. The image output may then be coupled to the output warning sounds or a Sprachausga be of clues.

Die "Draufsicht auf die Fahrzeugumgebung" sollte die für das Fahrzeug momentan wichtigen Abstandsinformationen übersichtlich darbieten. The "top view of the vehicle environment" should present the currently important for the vehicle distance information clearly. Hierzu sind berechnete Schemata der Umgebung besser geeignet als komplizierte Bilder, wo bei aber auch die schnelle Umrechnung der Bilder der Ka meraperspektive in eine Bild-Draufsicht möglich ist. For this purpose, calculated schemes around as complex images where at meraperspektive but also the fast conversion of images of the Ka in an image-top view is better suited possible. Es genügt die Darstellung der Konturen der in Kürze erreich baren Objekte entweder für sich allein und mit einer Füllfarbe ausgefüllt oder als Umrandung der umgerechneten Bild-Draufsicht. It is sufficient representation of the contours of the Reach cash shortly objects filled either alone and with a fill color or border of the converted image plan view. Details der Objekte und entfernte Objek te sollten nicht dargestellt werden, da diese nur die Aufmerksamkeit stören. Details of objects and removed valuables made should not be displayed, because they are inconvenient attention. Die schematisch gezeigten Objekte sollten sich innerhalb eines Bildschirmrasters befinden, das direkte Rückschlüsse auf Entfernungen zuläßt. The objects shown schematically should be located within a screen grid that allows for direct conclusions about distances. Es er scheint vorteilhaft, wenn die Kontur (oder ein Teil da von) des eigenen Fahrzeugs in der Draufsicht immer an derselben Stelle des Bildschirms angeordnet ist. There it appears advantageous if the contour of the own vehicle is always arranged in plan view at the same position of the screen (or a portion there of).

Details der Erfindung werden anhand eines Ausführungsbei spiels beschrieben. Details of the invention will be described by way of an exemplary embodiment game. Von den zugehörigen Zeichnungen zeigt: From the associated drawings:

Since the camera 8 is arranged in the rear of the traveling truck 2, the observed de surrounding region 7 extends from the vehicle 2 in a wedge shape towards the rear. Eine weitere Kamera könnte wie weiter oben be schrieben im Frontbereich des Fahrzeugs 2 angeordnet sein, wobei mittels dieser Kamera dann der Fahrbereich und/oder die Fahrbahn vor dem Fahrzeug 2 beobachtet wird. Another camera may be written as above in the front region of the vehicle 2 may be arranged, by means of this camera then the driving area and / or the road surface is observed ahead of the vehicle. 2

Der in Fig. 2 dargestellte Innenraumbereich des Fahr zeugs 2 umfaßt vornehmlich eine Instrumententafel 9 sowie eine Windschutzscheibe 10 in bekannter Ausführung. The interior region of the traveling truck 2 illustrated in Fig. 2 comprises mainly an instrument panel 9 and a windshield 10 in the prior art.

In der Instrumententafel 9 ist ein Bildschirm 11 eines Navigationssystems angeordnet, und ein weiterer Bild schirm 12 ist als Ersatz eines Innenrückspiegels an der Windschutzscheibe 10 befestigt. In the instrument panel 9, a screen 11 is arranged a navigation system, and a further image screen 12 is fixed as a replacement of an interior rearview mirror on the windshield 10th Beide Bildschirme 11 , 12 sind rechts neben der Darstellung des Fahrzeuginnenraum bereiches vergrößert gezeigt. Both screens 11, 12 area to the right of representation of the vehicle interior shown enlarged.

Die Bildschirme 11 , 12 und die Kamera 8 sind mit einer nicht dargestellten Steuereinheit verbunden, wobei die Steuereinheit die Kamerasignale verarbeitet und die Bild schirme 11 , 12 ansteuert. The screens 11, 12 and the camera 8 are connected to an unillustrated control unit, wherein the control unit processes the signals and the camera image screens 11, controls 12th Die Steuereinheit kann integra ler Bestandteil eines Bildschirms 11 , 12 oder der Kamera 8 sein oder sie ist separat im Kraftfahrzeug anzuordnen. The control unit may integra ler part of a screen 11, 12 or the camera 8 be or is to be arranged separately in the motor vehicle. Ihr werden zusätzlich zu den Kamerasignalen weitere Be triebskennwerte des Kraftfahrzeugs 2 zugeleitet, dies sind insbesondere ein Signal von der Fahrzeugzündung (Mo tor Ein/Aus), ein Geschwindigkeitssignal und ein Signal vom Schaltgetriebe, welches im Beispiel manuell über ei nen Schalthebel 13 bedienbar ist. Their addition to the camera signals further Be operating characteristics of the motor vehicle 2 supplied, these are in particular a signal from the vehicle ignition (Mo gate on / off), a speed signal and a signal from the transmission, which is manually operable in the example above ei NEN shift lever. 13 Die Art der bildlichen Darstellung der Kamerasignale auf den Bildschirmen 11 , 12 wird von der Steuereinheit in Abhängigkeit von den Be triebskennwerten eingestellt: The kind of the pictorial representation of the camera signals on the screens 11, 12 is by the control unit in dependence on the loading operating parameters set:

Bei nicht in Betrieb befindlichem Fahrzeug 2 (Zündung aus) wird auf die gesamte Vorrichtung zur Darstellung des Umgebungsbereiches abgestellt. When not in service, vehicle 2 (ignition) is turned on, the entire device for displaying of the surrounding area.

Wird die Zündung auf "Ein" gestellt, beginnt der Betrieb der Vorrichtung, wobei der Bildschirm 11 nicht mit Ka merasignalen beaufschlagt wird, sondern von der Navigati onsvorrichtung angesteuert wird. If the ignition is set to "On", the operation of the apparatus begins, the screen 11 is not applied with merasignalen Ka, but is driven by the Navigati onsvorrichtung. Der Bildschirm 12 wird jedoch derart angesteuert, daß das von der Kamera 8 auf genommene Realbild dargestellt wird. The screen 12 is however controlled such that represented by the camera 8 in real image taken. Es ist darauf hinzu weisen, daß dieses Realbild etwa dem entspricht, was ein Fahrer sieht, wenn er aus dem Heckfenster des Fahrzeugs 2 schaut (ohne Einschränkungen durch Haube und Säulen), al so keine spiegelbildliche Darstellung ist. It is pointed out that this real image corresponds approximately to that which provides a driver when he is looking out the rear window of the vehicle 2 is al so no mirror image representation (without being restricted by the hood and columns). Dies erfordert sicherlich eine kurze Gewöhnungszeit. This certainly requires a short familiarization period. Besteht der Wunsch nach einer spiegelbildlichen Darstellung, kann dies ein fach über die Steuereinheit realisiert werden. Is desirable to have a mirror image representation, this may be realized a multiple of the control unit. Der Fahrer sollte hier eine Vorwahlmöglichkeit erhalten. The driver should obtain a Pre-selection here.

Im Ausführungsbeispiel wird auf dem Bildschirm 12 grund sätzlich das Realbild dargestellt, wobei dieses Realbild jedoch über die Steuereir heit betriebskennwertabhängig eingestellt wird. In the embodiment wherein said real image is, however, set uniform operating characteristic depending on the Steuereir is shown in principle the real image on the screen 12. Bei Vorwärtsfahrt (erster bis fünfter Gang eingelegt) wird ein konstanter Bereich hinter dem Fahrzeug 2 dargestellt, der kleiner sein kann als der Be reich 7 , der bei Rückwärtsfahrt angezeigt wird. A constant area is displayed behind the vehicle 2 during forward travel (first inserted to fifth gear), which may be smaller than the rich Be 7 that is displayed when driving backwards. Dies wird elektronisch durch Bildauswahl oder über gesteuerte Optik der Kamera durch die Steuereinheit realisiert. This is realized by electronic image selection or via controlled optics of the camera by the control unit. Bild-Dar stellungswinkel und -helligkeit sind über Knöpfe 14 , 15 am Bildschirm 12 einstellbar, so daß die Darstellung in dividuellen Wünschen anzupassen ist. Image-Dar attitude angle and brightness are buttons 14, 15, so that the display is adjustable to adapt in dividual requirements on the screen 12th Auch an sich bekann te Memory-Funktionen sind integrierbar. te most well itself memory functions can be integrated.

Der Bildschirm 11 wird von der Vorrichtung, insbesondere der genannten Steuereinheit angesteuert, wenn der Rück wärtsgang eingelegt wird. The screen 11 is driven by the device, in particular said control unit when the back is inserted forward gear. Dann wird dort das Navigations system abgeschaltet und die "Draufsicht" auf den von der Kamera 8 aufgenommenen Bereich 7 dargestellt. Then there is the navigation system switched off and the "plan view" displayed on the area taken by the camera 8. 7 Dies ist möglich, da die Kamera 8 nicht nur die herkömmlich be kannten Daten des Realbildes liefert, sondern auch noch Entfernungsdaten zu den aufgenommenen Bildpunkten an die Steuereinheit übermittelt. This is possible because the camera 8 not only delivers the conventionally be known data of the real image, but also received more distance data to the captured image points to the control unit. Dies ist ein besonderer Vor teil der erfindungsgemäßen Vorrichtung, da jetzt eine Darstellungsart (Draufsicht) möglich wird, die direkten Rückschluß auf Entfernungen des Fahrzeugs 2 von Objekten der Umgebung zuläßt. This is a special part Before the inventive device, since now one representation (top view) is possible the direct conclusion distances of the vehicle 2 permits objects around. Es können vom Bildschirm 11 Entfer nungen zu diesen Objekten (Fahrzeug 3 ; Bürgersteig 4 ; La ternenmast 5 ; Ball 6 ) direkt abgelesen werden, was eine wesentliche Komfortverbesserung gegenüber herkömmlich be kannten Entfernungsanzeigen darstellt. It may from the screen 11 Entfer voltages to these objects (vehicle 3; sidewalk 4; La tern mast 5, ball 6) can be read directly, which is a significant improvement in comfort over conventionally be known distance displays. Von weiterem be sonderen Vorteil ist, daß die Darstellungen in Abhängig keit von der Fahrsituation eingestellt werden, was ablen kenden Bedienaufwand verhindert. Is that the representations in Depending strength are adjusted to the driving situation from further down specific advantage, which ablen kenden operating expenses prevented.

Die Darstellung der Draufsicht auf dem Bildschirm 11 er folgt unter Berücksichtigung der Fahrgeschwindigkeit, welche bei eingelegtem Rückwärtsgang normalerweise klei ner/gleich Null ist. The representation of the top view on the screen 11 it follows, taking into account the traveling speed, which normally klei ner when reverse gear / is equal to zero. Der Darstellungsmaßstab wird ge schwindigkeitsabhängig zwischen zwei oder drei Stufen verstellt, so daß ein Entfernungsbereich sichtbar ist, der auch Reaktionen des Fahrers zuläßt. The display scale is adjusted ge schwindigkeitsabhängig between two or three steps, so that a removal region is visible, which allows also reactions of the driver. Die Steuereinheit stellt die Heckkontur des eigenen Fahrzeugs 2 als festen Balken 16 am unteren Bildrand dar und zeigt im Beispiel von dort aus einen Bereich von etwas über drei Meter hin ter dem Fahrzeug 2 . The control unit, the rear contour of the own vehicle 2 as the solid bar 16 at the bottom of the screen and shows the example from there a range of about three meters towards the vehicle ter second Bei konstanter Geschwindigkeit von hier -0,8 m/s ist damit ein Fahrbereich darstellbar, der in den folgenden vier Sekunden erreicht würde. At a constant speed of this 0.8 m / s so that a driving range is displayed that would be achieved in the next four seconds.

Zur Verringerung der von der Steuereinheit zu verarbei tenden Daten werden die Kameradaten, die außerhalb des darzustellenden Entfernungsbereiches liegen, verworfen. In order to reduce to the processing by the control unit to data Tenden the camera data, that are outside the displayed distance range are discarded. Anschließend werden durch elektronische Bildverarbeitung die äußeren Konturen von Objekten der aufgenommenen Umge bung ermittelt und andere Objekte werden ebenfalls elimi niert. the outer contours of objects are determined the recorded Conversely bung then by electronic image processing and other objects are also defined elimi. Die Konturen werden ausgefüllt und dieses schema tische Bild der Draufsicht wird in einem Raster 17 darge stellt. The contours are completed and this schematic view of the plan view is in a grid 17 provides Darge.

Auf dem Bildschirm 11 werden neben der Draufsicht weitere Informationen ausgegeben. On the screen 11 in addition to the top view of further information to be output. Im Beispiel ist dies die Ent fernung zu dem Objekt, welches bei Geradeausfahrt als er stes erreicht wird (zwei Meter zum Ball 6 ). In the example, this is the Ent fernung to the object, which is achieved when driving straight ahead when he kits (two meters to the ball 6). Des weiteren wird die exakte Geschwindigkeit angezeigt und es könnten Fahrempfehlungen ausgegeben werden. Furthermore, the exact speed is displayed and it could driving recommendations are output.

Ist im Fahrzeug 2 nur der Bildschirm 12 vorhanden, kann die Darstellung der Draufsicht auch auf diesem Bildschirm 12 erfolgen, der dann betriebskennwertabhängig vom Real bild auf die Draufsicht und zurück umgeschaltet würde. Is in the vehicle 2, only the screen 12 is present, the representation of the top view can also be done on this screen 12, which would then operate characteristic value dependent image switched from Real to the top and back.
