Description
Die Erfindung betrifft eine Vorrichtung und ein Verfahren zum Darstellen der Umgebung eines Fahrzeugs.The invention relates to an apparatus and a method for representing the environment of a vehicle.
Bekannte Vorrichtungen zum Darstellen der Umgebung von Fahrzeugen werden meistens verwendet, um einen Fahrzeugführer bei schlechten Sichtverhältnissen, insbesondere bei Nacht, zu unterstützen. Dabei erfassen Restlichtverstärkerkameras oder Wärmebildkameras oder Nahbereichsinfrarotkameras in Fahrtrichtung die Umgebung eines Fahrzeugs, welche auf einem Monitor oder auf einem Head-Up-Dispay abgebildet wird. Anstelle von Restlichtverstärkerkameras oder Wärmebildkameras können auch Nahbereichsinfrarotkameras verwendet werden.Known devices for representing the environment of vehicles are mostly used to assist a driver in poor visibility, especially at night. In the process, residual-light intensifier cameras or thermal imaging cameras or close-range infrared cameras capture the surroundings of a vehicle, which is displayed on a monitor or on a head-up dispay. In addition to low-light amplification cameras or thermal imaging cameras, close-range infrared cameras can also be used.
Monitore als Anzeigeeinrichtung besitzen dabei den Nachteil, dass der Fahrzeugführer seinen Blick von der Fahrbahn abwenden muss, um die Darstellung der Umgebung auf dem Monitor zu erfassen.Monitors as a display device have the disadvantage that the driver has to look away from the road to capture the representation of the environment on the monitor.
Head-Up-Displays überwinden diesen Nachteil indem ein Projektor ein virtuelles Buid auf die Frontscheibe eines Fahrzeugs spiegelt, an welcher das virtuelle Bild an einen Rand des Sichtfelds des Fahrzeugführers reflektiert wird. Dabei kann das virtuelle Bild in Abhängigkeit von dessen Position ohne oder nur mit geringen Anpassungsleistungen des Auges an Entfernung und Helligkeit des Bildes wahrgenommen werden.Head-up displays overcome this disadvantage by having a projector mirror a virtual buid onto the windshield of a vehicle, at which the virtual image is reflected to an edge of the driver's field of vision. Depending on its position, the virtual image can be perceived in terms of the distance and brightness of the image with little or no adaptation of the eye.

Der Erfindung liegt daher das technische Problem zugrunde, eine Vorrichtung und ein Verfahren zum Darstellen der Umgebung eines Fahrzeugs zuschaffen, bei dem die Wahrnehmbarkeit durch den Fahrer verbessert wird.The invention is therefore based on the technical problem of providing an apparatus and a method for representing the environment of a vehicle, in which the visibility is improved by the driver.
Die Lösung des technischen Problems ergibt sich durch die Gegenstände mit den Merkmalen der Ansprüche 1 und 17. Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.The solution of the technical problem results from the objects with the features of
Hierbei umfasst eine Vorrichtung zum Darstellen der Umgebung eines Fahrzeugs, eine Kameraeinrichtung zum Erfassen von Objekten der Umgebung des Fahrzeugs und Bereitstellen visueller Informationen, mindestens eine Auswerteeinrichtung zum Verarbeiten bereitgestellter Informationen und eine Anzeigeeinrichtung, welche mit der Auswerteeinrichtung gekoppelt ist, um ein virtuelles Umgebungsbild zu erzeugen, welches die von der Kameraeinrichtung erfassten Objekte perspektivisch korrekt darstellt, wobei die Vorrichtung mindestens ein Mittel umfasst, welches zusätzliche Informationen bezüglich der Objekte bereitstellt, die von der Auswerteeinrichtung derart verarbeitbar sind, dass diese zusätzlichen Informationen im virtuellen Umgebungsbild, den entsprechenden Objekten zugeordnet, graphisch einblendbar sind, wobei das Mittel zum Bereitstellen zusätzlicher Informationen bezüglich der Objekte ein Navigationssystem ist, mittels dessen eine mögliche Bewegungsbahn eines Objektes ermittelt und im virtuellen Umgebungsbild dargestellt wird.In this case, a device for displaying the surroundings of a vehicle, a camera device for detecting objects of the surroundings of the vehicle and providing visual information, at least one evaluation device for processing provided information and a display device, which is coupled to the evaluation device to generate a virtual environment image which perspectively displays correctly the objects detected by the camera device, wherein the device comprises at least one means which provides additional information regarding the objects that are processable by the evaluation device, such that these additional information in the virtual environment image, associated with the corresponding objects, graphically can be faded in, wherein the means for providing additional information regarding the objects is a navigation system, by means of which a possible trajectory of an object is determined and i m virtual environment image is displayed.
Dadurch ergibt sich der Vorteil, dass ein Fahrer durch zusätzliche Informationen in einem virtuellen Umgebungsbild eine Fahrsituation schneller erfassen und genauer beurteilen kann. This results in the advantage that a driver can detect a driving situation faster and more accurately by additional information in a virtual environment image.
In einer bevorzugten Ausführungsform umfasst die Vorrichtung zum Darstellen der Umgebung eines Fahrzeugs eine Sensoreinrichtung, welche Zustandsgrößen von Objekten erfasst. Dabei kann die Sensoreinrichtung beispielsweise eine Radarsensoreinrichtung sein, mittels der beispielsweise unter Ausnutzung des Dopplereffekts Entfernungen, Relativgeschwindigkeiten und/oder Relativbeschleunigungen von Umgebungsobjekten ermittelt werden können.In a preferred embodiment, the device for representing the environment of a vehicle comprises a sensor device which detects state variables of objects. In this case, the sensor device can be, for example, a radar sensor device by means of which distances, relative speeds and / or relative accelerations of surrounding objects can be determined, for example by utilizing the Doppler effect.
In einer weiteren Ausführungsform der Vorrichtung wird als Mittel zum Bereitstellen zusätzlicher Informationen über Objekte einer Umgebung eines Fahrzeugs ein Datenspeicher verwendet. Dieser Datenspeicher kann beispielsweise fahrzeugspezifische Daten verschiedener Fahrzeugtypen enthalten, wobei ein zu einem Fahrzeugtyp zugehöriger Datensatz in eine Auswerteeinrichtung geladen wird, wenn beispielsweise ein vorausfahrendes Fahrzeug als entsprechender Fahrzeugtyp identifiziert wird. Ein solcher Datensatz kann beispielsweise Information über Masse und Art des Bremssystems des vorausfahrenden Fahrzeugs enthalten. Soll der Abstand des vorausfahrende Fahrzeugs beispielsweise im virtuellen Umgebungsbild eingeblendet werden, wenn ein Mindestabstand zu dem vorausfahrenden Fahrzeug unterschritten wird, können die Informationen über Masse und Art des Bremssystems des vorausfahrenden Fahrzeugs mit verwendet werden, um einen Mindestabstandswert zu bestimmen.In a further embodiment of the device, a data memory is used as means for providing additional information about objects of an environment of a vehicle. This data memory may contain, for example, vehicle-specific data of different types of vehicles, with a data record associated with a vehicle type being loaded into an evaluation device if, for example, a preceding vehicle is identified as the corresponding vehicle type. Such a data record may, for example, contain information about the mass and type of the braking system of the preceding vehicle. If the distance of the vehicle in front, for example, be displayed in the virtual environment image when a minimum distance to the vehicle ahead, below the information about the mass and type of braking system of the vehicle in front can be used to determine a minimum distance value.
Neben dem Einblenden zusätzlich bereitgestellter Informationen in ein virtuelles Umgebungsbild können diese Informationen von anderen Fahrzeugsystemen verwendet werden. So können zusätzlich bereitgestellt Informationen wie beispielsweise der Abstand zu einem vorausfahrenden Fahrzeug und/oder dessen Geschwindigkeit und/oder dessen Masse von einem Gurtstraffersystem oder einem Airbagsystem verarbeitet werden.In addition to displaying additional information provided in a virtual environment image, this information can be used by other vehicle systems. Thus, additionally provided information such as the distance to a preceding vehicle and / or its speed and / or its mass can be processed by a belt tensioner system or an airbag system.
In einer weiteren Ausführungsform der Vorrichtung werden zusätzliche Informationen über Objekte der Umgebung eines Fahrzeugs, die beispielsweise durch ein Sensorsystem oder ein Navigationssystem bereitgestellt werden, durch eine Auswerteeinrichtung derart verarbeitet, dass einzelne Objekte im virtuellen Umgebungsbild mit graphischen Mitteln hervorgehoben werden. So kann beispielsweise ein vorausfahrendes Fahrzeug im virtuellen Umgebungsbild hervorgehoben werden, wenn der Abstand zum vorausfahrenden Fahrzeug einen Mindestwert unterschritten hat. Dadurch wird ein Fahrer des Fahrzeugs rechtzeitig auf eine kritische Fahrsituation hingewiesen. Als graphische Mittel können zum Beispiel eine Farbänderung, Kontrasterhöhung, Einrahmung, Blinken und/oder Hinweispfeile verwendet werden, wobei das graphische Hervorheben durch akustische oder haptische Signale unterstützt werden kann.In a further embodiment of the device, additional information about objects of the surroundings of a vehicle, which are provided, for example, by a sensor system or a navigation system, is processed by an evaluation device such that individual objects in the virtual environment image are highlighted by graphical means. Thus, for example, a vehicle ahead in the virtual environment image can be highlighted if the distance to the vehicle in front has fallen below a minimum value. As a result, a driver of the vehicle is informed in good time of a critical driving situation. As a graphical means, for example, a color change, contrast enhancement, framing, flashing and / or arrows are used, wherein the graphical highlighting can be supported by acoustic or haptic signals.
In einer bevorzugten Ausführungsform ist die Kameraeinrichtung als Restlichtverstärkerkamera und/oder Wärmebildkamera ausgebildet. Diese Kamerasysteme sind geeignet, eine Umgebung bei Dunkelheit oder schlechten Sichtverhältnissen zu erfassen. Dabei hat eine Restlichtverstärkerkamera gegenüber einer Wärmebildkamera den Vorteil, dass diese sowohl warme als auch kalte Objekte erfasst, wie beispielsweise länger abgestellte Kraftfahrzeuge.In a preferred embodiment, the camera device is designed as a residual light amplifier camera and / or thermal imaging camera. These camera systems are capable of detecting an environment in darkness or poor visibility. In this case, a residual light amplifier camera compared to a thermal imager has the advantage that it detects both warm and cold objects, such as longer parked vehicles.
In einer weiteren Ausführungsform ist die Anzeigeeinrichtung als ein Head-Up-Display ausgebildet. Ein Vorteil eines Head-Up-Displays ist es, das ein virtuelles Umgebungsbild im Sichtbereich oder am Rand des Sichtbereichs eines Fahrers dargestellt werden kann. Die Augen des Fahrers müssen somit nur noch geringe oder gar keine Anpassungsleistungen zwischen dem Erfassen des realen Umgebungsbildes und des virtuellen Umgebungsbildes durchführen. Ein Nachteil dieser Head-Up-Displays ist es, dass sich keine Gegenstände innerhalb des Einspiegelwinkels des virtuellen Bildes befinden dürfen, weil diese das virtuelle Bild teilweise oder vollständig verdecken können.In a further embodiment, the display device is designed as a head-up display. One advantage of a head-up display is that a virtual environment image can be displayed in the field of vision or at the edge of the field of vision of a driver. The driver's eyes thus only have to perform little or no adaptation services between the detection of the real environment image and the virtual environment image. A disadvantage of these head-up displays is that no objects may be within the viewing angle of the virtual image because they may partially or completely obscure the virtual image.
In einer weiteren bevorzugten Ausführungsform ist die Anzeigeeinrichtung eine aktiv ansteuerbare durchsichtige Folie, welche beispielsweise aus organischen LED's besteht und auf oder in mindestens einer Scheibe eines Fahrzeugs angeordnet ist. Dabei bedeckt die Folie vorzugsweise die gesamte Fläche der Frontscheibe des Fahrzeugs. Es besteht auch die Möglichkeit, dass die Folie nur einen oder mehrere Teilbereiche der Frontscheibe bedeckt. Beispielsweise könnte die Folie nur die Hälfte der Frontscheibe auf der Fahrerseite bedecken.In a further preferred embodiment, the display device is an actively controllable transparent film which, for example, consists of organic LEDs and is arranged on or in at least one pane of a vehicle. In this case, the film preferably covers the entire surface of the windshield of the vehicle. There is also the possibility that the film covers only one or more subregions of the windshield. For example, the film could cover only half of the front window on the driver's side.
Eine aktiv ansteuerbare Folie als Anzeigeeinrichtung besitzt mehrere Vorteile. Eine Folie, die auf oder in einer Scheibe angeordnet ist, beansprucht keinen zusätzlichen Platz. Bei einer aktiv ansteuerbaren Folie ist ein veränderliches Darstellungsformat oder ein veränderlicher Darstellungsort mit geringem Aufwand realisierbar. Dabei könnte beispielsweise ein erzeugtes virtuelles Umgebungsbild auf der Frontscheibe ein reales Umgebungsbild Eins zu Eins überlagern oder von diesem versetzt angeordnet sein. Ein weiterer Vorteil einer ansteuerbaren Folie gegenüber einem Head-Up-Display besteht darin, dass es nicht notwendig ist einen Einspiegelbereich innerhalb eines Armaturenbretts freizuhalten. Ein veränderbares Anordnen des virtuellen Umgebungsbildes erfordert bei einem Head-Up-Display ein aufwendiges Spiegelsystem.An actively controllable film as a display device has several advantages. A film placed on or in a disk does not take up any extra space. With an actively controllable film, a variable presentation format or a variable presentation site can be realized with little effort. In this case, for example, a generated virtual environment image on the windshield could superimpose a real environment image one to one or be offset from it. Another advantage of a controllable film over a head-up display is that it is not necessary to keep a viewing area within a dashboard clear. A variable arranging the virtual environment image requires a complex mirror system in a head-up display.
Weitere alternative Anzeigeeinrichtungen sind eine LCD-Anzeige, welche ebenfalls in einer Frontscheibe eines Fahrzeugs eingearbeitet sein kann, die unter Einfluss einer angelegten Spannung ihr Reflexionsvermögen ändert, oder ein Hologramm in einem Frontscheibenbereich. Further alternative display devices are an LCD display, which may also be incorporated in a windscreen of a vehicle that changes its reflectivity under the influence of an applied voltage, or a hologram in a windscreen area.
In einer weiteren Ausführungsform umfasst die Vorrichtung zum Darstellen einer Fahrzeugumgebung Mittel, mit denen die Blickrichtung eines Fahrers erfassbar ist. Dadurch ist es beispielsweise möglich, ein virtuelles Umgebungsbild in Abhängigkeit der ermittelten Blickrichtung zu positionieren. So wird beispielsweise in einer Rechtskurve. in welcher sich das Sichtfeld eines Fahrers üblicherweise nach rechts verschiebt, das virtuelle Umgebungsbild dem Sichtfeld des Fahrers entsprechend nach rechts verschoben dargestellt. Das virtuelle Umgebungsbild wandert mit der Blickrichtung des Fahrers mit, wodurch der Fahrer seinen Blick nicht von der Fahrtrichtung abwenden muss, um beispielsweise ein virtuell erzeugtes Umgebungsbild auf einem Monitor oder einem fest positionierten Head-Up-Display zu erfassen. Des Weiteren kann eine erfasste Blickrichtung dazu verwendet werden, zusätzliche Informationen nur in einem Bereich des virtuellen Umgebungsbildes einzublenden, der von der erfassten Blickrichtung abhängt.In a further embodiment, the device for representing a vehicle environment comprises means with which the viewing direction of a driver can be detected. This makes it possible, for example, to position a virtual environment image as a function of the determined viewing direction. For example, in a right turn. in which the field of vision of a driver usually shifts to the right, the virtual environment image is shown displaced to the right according to the field of vision of the driver. The virtual environment image moves with the driver's line of sight, as a result of which the driver does not have to avert his gaze from the direction of travel in order, for example, to capture a virtually generated environmental image on a monitor or a fixedly positioned head-up display. Furthermore, a detected viewing direction can be used to display additional information only in a region of the virtual environment image that depends on the detected viewing direction.
In einer Ausführungsform bestehen die Mittel zum Erfassen der Blickrichtung eines Fahrers aus einer Kamera, welche mit einer Auswerteeinrichtung verbunden ist. Dabei umfasst die Kamera sowohl Infrarotdioden als auch einen Detektor. Mit den Infrarotdioden werden die Augen des Fahrers beleuchtet und die reflektierte Infrarotlichtleistung mit dem Detektor erfasst. Dieser übermittelt das Messergebnis an die Auswerteeinrichtung, in welcher die Blickrichtung des Fahrers ermittelt wird.In one embodiment, the means for detecting the viewing direction of a driver consist of a camera, which is connected to an evaluation device. The camera includes both infrared diodes and a detector. The infrared diodes illuminate the driver's eyes and detect the reflected infrared light output with the detector. This transmits the measurement result to the evaluation device, in which the driver's line of sight is determined.
