- a device for improving the visibility in a motor vehicle is already known.
- a signaling device for example a monitor or a head-up display
- the driver of the motor vehicle is informed of driver information about the course of the road and / or about objects in the surroundings of the motor vehicle.
- an infrared-sensitive image sensor system is provided whose signals are processed in such a way that corresponding markings for limiting the course of the lane are superimposed into the display.
- the night vision device with the features of the main claim has the advantage that a struck or a beaten track of the vehicle by means of a positioning and / or a direction of travel sensor is determined. This makes it possible, even without an optical evaluation of the driving situation in front of the vehicle to give the driver an optical support in a representation of a night vision scenery in front of the vehicle. Thus, it is also possible to provide such information to the driver when an image evaluation, e.g. due to precipitation, poor visibility or missing road markings is not possible. In particular, it is advantageous to assist the driver in a night drive by evaluating data that is itself determined by a vehicle sensor system without having to carry out an optical image evaluation with a mostly high computational expenditure.
- the direction of travel sensor is a steering angle sensor. This makes it possible for the driver's current steering angle to be used for prediction of a travel path. Because the currently chosen steering angle can be displayed directly in the road ahead of the vehicle to project a lane course. The driver can thus recognize with which distance he will drive past a roadside or obstacles. Thus, he can also recognize whether a steering correction is required. This is particularly advantageous if the driver can only estimate distances to side obstacles poorly due to poor visibility.

Description
Nachtsichteinrichtung Night vision device
Stand der TechnikState of the art
Die Erfindung geht aus von einer Nachtsichteinrichtung nach der Gattung des Hauptanspruchs. Aus der DE 102 53 510 ist bereits eine Vorrichtung zur Verbesserung der Sicht in einem Kraftfahrzeug bekannt. Über ein Signalisierungsmittel, beispielsweise einen Monitor oder ein Head-Up-Display, werden dem Fahrer des Kraftfahrzeugs Fahrerinformationen über den Fahrbahnverlauf und/oder über Objekte in der Umgebung des Kraftfahrzeugs angezeigt. Um den Fahrbahnverlauf erfassen zu können, ist ein infrarotempfindliches Bildsensorsystem vorgesehen, dessen Signale derart verarbeitet werden, dass entsprechende Markierungen zur Begrenzung des Fahrbahnverlaufs in die Anzeige eingeblendet werden.
The invention relates to a night vision device according to the preamble of the main claim. From DE 102 53 510 a device for improving the visibility in a motor vehicle is already known. By means of a signaling device, for example a monitor or a head-up display, the driver of the motor vehicle is informed of driver information about the course of the road and / or about objects in the surroundings of the motor vehicle. In order to be able to detect the course of the lane, an infrared-sensitive image sensor system is provided whose signals are processed in such a way that corresponding markings for limiting the course of the lane are superimposed into the display.
Vorteile der ErfindungAdvantages of the invention
Die erfindungsgemäße Nachtsichteinrichtung mit den Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, dass ein eingeschlagener bzw. ein einzuschlagender Fahrweg des Fahrzeugs mittels eines Ortungs- und/oder eines Fahrtrichtungssensors bestimmt wird. Hierdurch ist es möglich, auch ohne eine optische Auswertung der Fahrsituation vor dem Fahrzeug dem Fahrer eine optische Unterstützung bei einer Darstellung einer Nachtsichtszenerie vor dem Fahrzeug zu geben. Damit ist es auch möglich, dem Fahrer derartige Informationen dann bereitzustellen, wenn eine Bildauswertung z.B. aufgrund von Niederschlägen, schlechter Sicht oder fehlenden Straßenmarkierungen nicht möglich ist. Insbesondere ist es vorteilhaft, den Fahrer bei einer Nachtfahrt zu unterstützen, indem alleine von einer Fahrzeugsensorik selbst ermittelte Daten ausgewertet werden, ohne eine optische Bildauswertung mit einem zumeist hohem Rechenaufwand vornehmen zu müssen.The night vision device according to the invention with the features of the main claim has the advantage that a struck or a beaten track of the vehicle by means of a positioning and / or a direction of travel sensor is determined. This makes it possible, even without an optical evaluation of the driving situation in front of the vehicle to give the driver an optical support in a representation of a night vision scenery in front of the vehicle. Thus, it is also possible to provide such information to the driver when an image evaluation, e.g. due to precipitation, poor visibility or missing road markings is not possible. In particular, it is advantageous to assist the driver in a night drive by evaluating data that is itself determined by a vehicle sensor system without having to carry out an optical image evaluation with a mostly high computational expenditure.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Hauptanspruch angegebenen Nachtsichteinrichtung möglich. Besonders vorteilhaft ist, dass der Fahrtrichtungssensor ein Lenkwinkelsensor ist. Damit wird es ermöglicht, dass der vom Fahrer aktuell eingeschlagene Lenkwinkel zur Prädiktion eines Fahrwegs verwendet wird. Denn der aktuell eingeschlagene Lenkwinkel kann zur Projektion eines Fahrbahnverlaufs unmittelbar in den Straßenverlauf vor dem Fahrzeug eingeblendet werden. Der Fahrer kann somit erkennen, mit welchem Abstand er an einem Straßenrand bzw. an Hindernissen vorbeifahren wird. Somit kann er ebenfalls erkennen, ob eine Lenkkorrektur erforderlich ist. Dies ist insbesondere dann vorteilhaft, wenn der Fahrer aufgrund schlechter Sichtverhältnisse Entfernungen auch zu seitlichen Hindernissen nur schlecht abschätzen kann.The measures listed in the dependent claims advantageous refinements and improvements of the main claim night vision device are possible. It is particularly advantageous that the direction of travel sensor is a steering angle sensor. This makes it possible for the driver's current steering angle to be used for prediction of a travel path. Because the currently chosen steering angle can be displayed directly in the road ahead of the vehicle to project a lane course. The driver can thus recognize with which distance he will drive past a roadside or obstacles. Thus, he can also recognize whether a steering correction is required. This is particularly advantageous if the driver can only estimate distances to side obstacles poorly due to poor visibility.
Weiterhin ist es vorteilhaft, mit einem Ortungssensor eine aktuelle Position des Fahrzeugs zu bestimmen und z.B. aus einem Vergleich mit einer digitalen Karte oder einerFurthermore, it is advantageous to use a position sensor to determine a current position of the vehicle and, e.g. from a comparison with a digital map or a
Auswertung einer Ortsänderung den vor dem Fahrzeug liegenden Straßenverlauf bzw. die verfolgte Fahrtrichtung zu ermitteln. Dieser Straßenverlauf, dem das Fahrzeug in seiner weiteren Fahrt folgen muss, kann entsprechend in der Anzeige eingeblendet werden. Hierdurch ist es insbesondere möglich, den Fahrer rechtzeitig vor scharfen Kurven oder ähnlichen Gefahrenstellen zu warnen, da ein entsprechender Straßenverlauf
vorausschauend in die Anzeige eingetragen werden kann. Hierbei ist es insbesondere vorteilhaft, den Straßenverlauf insbesondere zusätzlich in eine Kartendarstellung einzublenden. Der Fahrer kann hierdurch vor allem unter Berücksichtigung der aktuellen Position des Fahrzeugs den Straßenverlauf in seiner Gesamtheit erkennen und sein Fahrverhalten entsprechend anpassen.Evaluation of a change in location to determine the road ahead or the pursued direction of travel. This road course, which the vehicle must follow in its further journey, can be displayed accordingly in the display. This makes it possible, in particular, to warn the driver in good time of sharp bends or similar danger spots, since a corresponding course of the road can be entered in the display in a forward-looking manner. In this case, it is particularly advantageous to additionally show the course of the road in particular in a map display. The driver can thereby recognize the road course in its entirety and adjust his driving behavior, especially taking into account the current position of the vehicle.
Es ist ferner vorteilhaft, zusätzlich die Möglichkeit zu geben, dass die Nachtsichteinrichtung den Verlauf von Fahrbahnbegrenzungen und/oder Markierungen aus einem aufgenommenen Kamerabild ermittelt und diese in der Anzeige bevorzugt auch hervorhebt. Im Vergleich zu den übrigen, durch die Sensorik ermitteltenIt is also advantageous to additionally allow the possibility that the night-vision device determines the course of road boundaries and / or markings from a recorded camera image and also emphasizes these in the display. Compared to the rest, determined by the sensors
Markierungen kann damit ein Vergleich zwischen den optisch erfassten und den anderweitig erfassten Markierungen durch den Fahrer durchgeführt werden. Er kann somit auch abschätzen, ob tatsächlich eine gute Erfassung des Fahrwegs vor dem Fahrzeug durchgeführt wurde, oder ob die Unterstützung möglicherweise gestört ist. Wird der eingeschlagene Fahrweg mit einem einzuschlagenden Fahrweg verglichen, kann der Fahrer erkennen, ob das Lenkrad richtig eingestellt ist, um dem einzuschlagenden Fahrweg zu folgen.Markings can thus be carried out a comparison between the optically detected and the otherwise detected markings by the driver. He can thus also estimate whether in fact a good detection of the route in front of the vehicle was carried out, or whether the support may be disturbed. If the taken track is compared with a track to be taken, the driver can recognize whether the steering wheel is set correctly to follow the track to be taken.
Es ist ferner vorteilhaft, wenigstens ein weiteres Warn- oder Hinweissymbol in die Anzeige einzublenden. Hierdurch kann der Fahrer auf Kurven, mögliche gefährlicheIt is also advantageous to display at least one further warning or warning symbol in the display. This allows the driver to turn, possibly dangerous

Es ist weiterhin vorteilhaft eine Bedieneinheit vorzusehen, mit der der Fahrer die von ihm gewünschte Darstellung eines eingeschlagenen bzw. einzuschlagenden Fahrwegs auswählen kann. Je nach seinen Wünschen kann er dabei entsprechend mehr oder weniger Hilfsdarstellungen in die Anzeige mit einbeziehen.It is furthermore advantageous to provide an operating unit with which the driver can select the desired representation of a path taken or to be driven in. Depending on his wishes, he may include more or less auxiliary representations in the advertisement.

In der Figur 1 ist ein Kraftfahrzeug 1 schematisch in einer Aufsicht dargestellt. An einer Vorderseite 2 des Fahrzeugs 1 ist eine Kamera 3 derart angeordnet, dass die Kamera 3 den Fahrraum vor dem Fahrzeug 1 beobachtet. Die Kamera 3 ist insbesondere als eine elektronische Kameraeinrichtung ausgeführt, die neben dem für das menschliche Auge sichtbaren Wellenlängenbereich auch den nahen Infrarotbereich abdeckt. Die Kamera 3 ist vorzugsweise in einem Wellenlängenbereich zwischen 400 und 980 nm empfindlich. Die Kamera 3 ist hierzu beispielsweise als eine CCD-Kamera ausgeführt. Über eine Videoleitung bzw. eine Videodatenbusleitung 4 werden die Bilddaten an eineIn the figure 1, a motor vehicle 1 is shown schematically in a plan view. On a front side 2 of the vehicle 1, a camera 3 is arranged such that the camera 3 observes the driving space in front of the vehicle 1. The camera 3 is embodied in particular as an electronic camera device which, in addition to the wavelength range visible to the human eye, also covers the near infrared range. The camera 3 is preferably sensitive in a wavelength range between 400 and 980 nm. For this purpose, the camera 3 is designed, for example, as a CCD camera. Via a video line or a video data bus 4, the image data to a
Auswerteeinheit 5 im Fahrzeug 1 übertragen. Um die Szenerie vor dem Fahrzeug 1 besser auszuleuchten, ist in einer Ausführungsform eine Beleuchtungseinrichtung 6 vorgesehen, bei der Infrarotlichtquellen 7, z.B. Infrarotleuchtdioden, Licht in den Fahrraum vor dem Fahrzeug 1 abstrahlen. Die Beleuchtungseinrichtung 6 wird beispielsweise von der Auswerteeinheit 5 angesteuert. Die Auswerteeinheit 5 weist eine Recheneinheit 9 auf, die in einer bevorzugten Ausgestaltung eine Bildverarbeitung der aufgenommenen Bilddaten ermöglicht. Die Bilddaten werden von der Auswerteeinheit 5 an eine Anzeigeeinheit 8 im Fahrzeug weitergeleitet. Die Anzeigeeinheit 8 ist beispielsweise als eine so genannte Head-Up- Anzeige im Fahrzeug ausgeführt. Hierbei wird in eine Windschutzscheibe oder auf eine Projektionseinheit vor dem Fahrer ein virtuelles Bild der Fahrsituation vor demTransfer evaluation unit 5 in the vehicle 1. In order to better illuminate the scenery in front of the vehicle 1, in one embodiment a lighting device 6 is provided, in which infrared light sources 7, e.g. Emit infrared light emitting diodes, light in the traffic ahead of the vehicle 1. The illumination device 6 is driven, for example, by the evaluation unit 5. The evaluation unit 5 has a computing unit 9 which, in a preferred embodiment, enables image processing of the recorded image data. The image data are forwarded by the evaluation unit 5 to a display unit 8 in the vehicle. The display unit 8 is designed, for example, as a so-called head-up display in the vehicle. Here, a virtual image of the driving situation in front of the driver in a windshield or on a projection unit
Fahrzeug projiziert. In einer besonderen Ausführungsform erfolgt dabei eine so genannte kontaktanaloge Anzeige, bei der sich die projizierten Bildelemente derart mit der für den Fahrer durch die Scheibe sichtbaren Szenerie vor dem Fahrzeug überdecken, dass die eingeblendeten Markierungen für den Fahrer in Bezug zu den realen Objekten vor ihm liegend erscheinen. In einer weiteren Ausführungsform kann die Anzeigeinheit 8 auch als eine Anzeige in einem Kombinationsinstrument oder in einer Mittelkonsole des Fahrzeugs ausgeführt sein. Hierbei wird in einem Bildschirm die entsprechende Szenerie vor dem Fahrzeug dargestellt.Vehicle projects. In a particular embodiment, a so-called contact-analogue display takes place, in which the projected image elements overlap with the scene visible to the driver through the windshield in front of the vehicle such that the overlaid markings for the driver lie in front of him with respect to the real objects appear. In another embodiment, the display unit 8 may also be implemented as an indicator in a combination instrument or in a center console of the vehicle. Here, the corresponding scene in front of the vehicle is displayed in a screen.
In einer ersten Ausführungsform ist die Auswerteeinheit 5 mit einem LenkwinkelsensorIn a first embodiment, the evaluation unit 5 is provided with a steering angle sensor
10 verbunden, der einen Lenkeinschlag der Vorderachse 19 ermittelt. Der Lenkeinschlag wird durch den Fahrer über ein Lenkrad 18 eingestellt. In Abhängigkeit von dem aktuell eingeschlagenen, über den Lenkwinkelsensor 10 erfassten Lenkwinkel berechnet die Auswerteeinheit 5 einen Fahrweg, den das Fahrzeug bei einem ungeänderten, eingestellten Lenkwinkel wahrnehmen wird. Dieser Fahrweg wird mittels Markierungen
in das von der Kamera 3 aufgenommene Bild eingeblendet. Somit kann der Fahrer den vor dem Fahrzeug liegenden Fahrweg erkennen.10, which determines a steering angle of the front axle 19. The steering angle is adjusted by the driver via a steering wheel 18. Depending on the currently chosen, detected via the steering angle sensor 10 steering angle calculates the evaluation unit 5 a track that the vehicle will perceive at an unchanged, set steering angle. This track is marked by markings into the picture taken by the camera 3. Thus, the driver can recognize the road ahead of the vehicle.
In einer weiteren Ausführungsform ist die Auswerteeinheit 5 mit einer Ortungseinrichtung 11 verbunden. Die Ortungseinrichtung 11 verfügt insbesondere über eine Antenne 12, mittels der eine Satellitenortung durchgeführt wird. Aus der Änderung der Ortsposition kann somit zunächst ein Bewegungsvektor ermittelt werden. Aus diesem Bewegungsvektor ist ebenfalls ein aktueller, von dem Fahrzeug eingeschlagener Fahrweg bestimmbar und in der Anzeige darstellbar. In einer alternativen Ausführungsform kann auch eine Ortung im Sinne einer Feststellung einer Ortsänderung mittel eines RadsensorsIn a further embodiment, the evaluation unit 5 is connected to a locating device 11. The locating device 11 has in particular an antenna 12, by means of which a satellite positioning is carried out. From the change of the spatial position, a motion vector can thus be determined first. For this movement vector is also a current, taken by the vehicle track determined and displayed in the display. In an alternative embodiment, a location in the sense of a determination of a change in location means of a wheel sensor
16 und eines Drehratensensors 15 ermittelt werden. Diese Sensoren können alternativ auch zu einer Unterstützung der Satellitenordnung für den Fall herangezogen werden, dass kein Satellitenempfang möglich ist.16 and a rotation rate sensor 15 are determined. Alternatively, these sensors can also be used to support the satellite order in the event that no satellite reception is possible.
In einer weiteren Ausführungsform kann die Ortungseinheit auch auf eineIn a further embodiment, the locating unit can also be applied to a
Straßenkartenbasis 13 zugreifen. Diese Straßenkartenbasis 13 ist z.B. eine in einem Speicher abgelegte digitale Karte eines Straßennetzes ausgeführt. Indem die aktuelle Position des Fahrzeugs von der Ortungseinrichtung 11 bestimmt und mit der gespeicherten Straßenkartenbasis 13 verglichen wird, kann die Ortungseinheit eine Position des Fahrzeugs auf einer Straße bestimmen. Damit ist es aber auch möglich, aus der Straßenkartenbasis den weiteren Straßenverlauf abzurufen. Dieser Straßenverlauf wird an die Auswerteeinheit 5 übertragen. Die Auswerteeinheit 5 stellt nun den weiteren Straßenverlauf ausgehend von der aktuellen Position des Fahrzeug ebenfalls überlagernd der aktuellen Fahrsituation in der Anzeigeeinheit 8 dar.Road map base 13 access. This road map base 13 is e.g. executed in a memory stored digital map of a road network. By determining the current position of the vehicle from the locating device 11 and comparing it with the stored roadmap base 13, the locating unit may determine a position of the vehicle on a road. But this also makes it possible to retrieve the further course of the road from the road map base. This road course is transmitted to the evaluation unit 5. The evaluation unit 5 now represents the further course of the road, starting from the current position of the vehicle, also overlapping the current driving situation in the display unit 8.
Die Auswerteeinheit 5 ist ferner mit einer Bedieneinheit 14 verbunden. Mit der Bedieneinheit 14 kann die Kamera 3 aktiviert werden, aber auch der Auswerteeinheit 5 mitgeteilt werden, welche ergänzenden Markierungen in der Anzeige 8 dargestellt werden sollen. So kann der eingeschlagene, mit dem Lenkwinkelsensor erfasste Fahrweg, der von der Ortungseinheit vorgegebene Fahrweg oder der von der Ortungseinheit in derThe evaluation unit 5 is further connected to an operating unit 14. The camera 3 can be activated with the operating unit 14, but also the evaluation unit 5 can be informed which supplementary markings are to be displayed in the display 8. Thus, the embarked, with the steering angle sensor detected travel, the predetermined by the locating unit track or the locating unit in the
Verbindung mit der Straßenkarte vorgegebene, einzuschlagende Fahrweg jeweils getrennt, aber auch in Kombination gewählt werden. Zusätzlich ist es auch möglich, ergänzend hierzu die von der Auswerteeinheit 5 mittels der Recheneinheit 9 aus dem erfassten Bildsignal ermittelten Fahrbahnbegrenzungen bzw. Fahrbahnmarkierungen durch die Einblendung von Zusatzsymbolen in der Anzeige 8 besonders hervorzuheben.
Die Kamera 3 kann die Szenerie vor dem Fahrzeug sowohl bei Tag, als auch bei Nacht erfassen. Insbesondere ist ihre Verwendung als eine Nachtsichtvorrichtung jedoch vorteilhaft, da es bei Nacht für einen Fahrer besonders schwer ist, insbesondere bei schlechten Sichtverhältnissen, den Fahrbahnverlauf vor ihm zu erkennen.Connection to the road map given, to be driven roadway each separately, but also be selected in combination. In addition, it is also possible to additionally emphasize the lane boundaries or lane markings determined by the evaluation unit 5 by means of the arithmetic unit 9 from the detected image signal by the insertion of additional symbols in the display 8. The camera 3 can detect the scenery in front of the vehicle both day and night. In particular, however, their use as a night-vision device is advantageous because at night it is particularly difficult for a driver, especially in poor visibility, to recognize the road ahead of him.
In der Figur 2 ist ein erstes Ausführungsbeispiel für eine Darstellung in der Anzeige 8 gezeigt. Ein linker Fahrbahnrand 21, ein rechter Fahrbahnrand 22 sowie die dazwischen liegende Fahrbahn 20 einschließlich von Mittelstreifenmarkierungen 23 sind für den Fahrer in dem von der Kamera 3 erfassten und in der Anzeigeeinheit 8 dargestellten Bild sichtbar. Erfolgt die Anzeige in einem Head-Up-Display mit einer kontaktanalogen Anzeige, so ist die Position des Kamerabildes an die tatsächliche Ausgestaltung der Umgebung vor dem Fahrzeug anzupassen, wie sie für den Fahrer durch die Windschutzscheibe sichtbar ist.FIG. 2 shows a first exemplary embodiment for a representation in the display 8. A left-hand lane edge 21, a right-hand lane edge 22 and the intervening lane 20, including median markings 23, are visible to the driver in the image captured by the camera 3 and displayed in the display unit 8. If the display is in a head-up display with a contact-analogue display, the position of the camera image must be adapted to the actual configuration of the surroundings in front of the vehicle, as it is visible to the driver through the windshield.
Zwischen dem rechten Fahrbahnrand 22 und dem Mittelstreifen 23 verläuft die Fahrspur, die das Fahrzeug nehmen soll. In dem hier dargestellten Ausführungsbeispiel ist durch eine linke gestrichelte Linie 24 und durch eine rechte gestrichelte Linie 25 eine Fahrspur eingezeichnet, deren Ermittlung auf dem aktuell eingestellten Lenkwinkel des Fahrzeugs beruht. Der Fahrer kann somit erkennen, dass er das Fahrzeug derzeit ohne eineBetween the right lane edge 22 and the median strip 23 runs the lane that is to take the vehicle. In the embodiment shown here, a lane is drawn by a left dashed line 24 and by a right dashed line 25, the determination of which is based on the currently set steering angle of the vehicle. The driver can thus recognize that he is currently without a vehicle
Änderung des Lenkwinkels in der vorgegebenen Fahrbahn bzw. Fahrspur bewegt. Würde nun im Bereich der Fahrbahn 20 ein Hindernis auftauchen, so könnte der Fahrer erkennen, ob die von ihm eingestellte Fahrspur um das Hindernis herum führt, oder ob er eine Korrektur des eingeschlagenen Lenkwinkels vornehmen muss. Er könnte so z.B. auch erkennen, ob ein Schlagloch auf seinem Weg liegt und er ausweichen sollte. Macht die Straße eine Kure nach rechts oder links, so müsste der Fahrer mit dem Lenkrad 18 den eingeschlagenen Lenkwinkel korrigieren. Entsprechend würden sich dann auch die angezeigten Markierungen 24, 25 entsprechend der Lenkraddrehung nach rechts bzw. nach links neigen. Anstelle einer reinen Seitenbegrenzungsdarstellung, wie es hier mit den Markierungen 24, 25 erfolgt ist, wäre es auch möglich, eine von den MarkierungenChanging the steering angle in the given lane or lane moves. If an obstacle now emerges in the area of the roadway 20, the driver could recognize whether the lane set by him leads around the obstacle or whether he must make a correction of the steering angle taken. He could, for example, also recognize if a pothole is on his way and he should dodge. If the road turns to the right or left, the driver would have to correct the steering angle with the steering wheel 18. Accordingly, then the displayed markings 24, 25 would tilt according to the steering wheel rotation to the right or to the left. Instead of a pure page boundary representation, as has been done here with the markers 24, 25, it would also be possible to use one of the markers
24, 25 begrenzte Fahrspur vollständig durch eine großräumige Markierung in das Anzeigebild einzutragen. Ferner wäre es auch möglich, eine Fahrspur als eine Doppelspur entsprechend dem Verlauf der Räder in die Anzeige einzutragen. Eine solche Darstellung könnte z.B. durch eine entsprechende, jeweilige Verbreiterung der Markierungen 24, 25 zum Inneren der Fahrspur erfolgen.
In der Figur 3 ist ein weiteres Ausfuhrungsbeispiel einer Darstellung in der Anzeigeeinheit 8 gezeigt. In dem vorliegenden Fall ist eine Linie 26 zentral in eine Fahrspur zwischen einer Mittelspurmarkierung 31 und einem rechten Fahrbahnrand 32 eingetragen. Ferner ist in der Anzeige auch eine linke Fahrspurbegrenzung 33 und die24, 25 limited lane completely by a large-scale mark in the display image to enter. Furthermore, it would also be possible to enter a lane as a double track corresponding to the course of the wheels in the display. Such a representation could be made, for example, by a corresponding widening of the markings 24, 25 to the interior of the traffic lane. FIG. 3 shows a further exemplary embodiment of a representation in the display unit 8. In the present case, a line 26 is registered centrally in a traffic lane between a center lane marker 31 and a right lane edge 32. Further, in the display, a left lane boundary 33 and the
Fahrbahn 30 selbst dargestellt. Ergänzend hierzu sind durch Analyse des Kamerabildes der Verlauf der Mittelspurmarkierung 31 und des rechten Fahrbahnrandes 32 rechnerisch ermittelt worden. Daher wurden entsprechend einer Ausfuhrungsform Markierungen 34 zur Hervorhebung des Mittelsstreifens und Markierungen 35 zur Hervorhebung der rechten Fahrbahnbegrenzung zusätzlich in das Anzeigenbild eingetragen. Durch denLane 30 itself shown. In addition to this, the course of the center track mark 31 and of the right-hand roadside edge 32 have been determined by analysis of the camera image. Therefore, according to an embodiment, markings 34 for highlighting the center strip and markings 35 for emphasizing the right-hand road boundary were additionally entered into the display image. By the
Vergleich des eingeschlagenen Fahrwegs gemäß der Linie 26 mit den aus der Bildanalyse bestimmten Fahrbahnbegrenzungen 32, 34 kann der Fahrer erkennen, inwieweit er in der Fahrspur liegt.Comparison of the chosen travel path according to the line 26 with the roadway boundaries 32, 34 determined from the image analysis, the driver can see how far he is in the lane.
In einer weiteren Ausführungsform kann die Mittelmarkierung in Form der Linie 26 auch aus einem Straßenverlauf ausgehend von der aktuellen Position des Fahrzeugs bestimmt werden. Über die Ortungseinrichtung 11 wird zunächst die Position des Fahrzeugs in einem Straßennetz festgestellt und im Anschluss dazu, insbesondere unter Berücksichtigung der Fahrtrichtung des Fahrzeugs, der zu erwartende Straßenverlauf bestimmt und in die Anzeigeeinrichtung entsprechend der Darstellung in der Figur 3 eingetragen. Im vorliegenden Fall folgt im Straßenverlauf ausgehend von der aktuellen Position des Fahrzeugs eine Rechtskurve. Dies ist aus einem Biegen der Mittellinie 26 nach rechts erkennbar. In einer weiteren Ausführungsform kann zur Unterstützung auch ein Hinweissymbol 36 in die Anzeige eingetragen werden, das den Fahrer auf eine Rechtskurve hinweist. In besonderen Gefahrensituationen kann zusätzlich einIn a further embodiment, the middle marking in the form of the line 26 can also be determined from a road course starting from the current position of the vehicle. About the locating device 11, the position of the vehicle is first determined in a road network and then determined, in particular taking into account the direction of travel of the vehicle, the expected road course and entered into the display device according to the illustration in Figure 3. In the present case, a right-hand turn follows in the course of the road starting from the current position of the vehicle. This can be seen from a bending of the center line 26 to the right. In a further embodiment, a hint symbol 36 can also be entered in the display for assistance, which points the driver to a right turn. In special danger situations can additionally one
Warnsymbol 37 in die Anzeige eingeblendet werden, das ebenfalls den Fahrer auf eine möglicherweise gefährliche Fahrstreckenpassage hinweist. Diese Informationen können mit in der Straßenkartenbasis 13 zu dem jeweiligen Straßenstück abgelegt sein.Warning symbol 37 are displayed in the display, which also indicates the driver on a potentially dangerous route passage. This information can be stored in the road map base 13 to the respective street piece.
In einer weiteren Ausführungsform ist es statt der Darstellung einer Mittelmarkierung auch möglich, für einen aus der Straßenkartenbasis ermittelten Fahrweg eine linke Markierung 38 und eine rechte Markierung 39 in die Fahrbahn 30 einzutragen. Eine entsprechende Darstellung ist in der Figur 4 gezeigt. Entsprechend ist es auch möglich, sowohl die Mittelmarkierung 26, z.B. für einen aus der Ortung bestimmten Straßenverlauf zusammen mit Seitenmarkierungen 38, 39 für einen aus dem
eingeschlagenen Lenkwinkel heraus bestimmten Straßenverlauf gleichzeitig in die Anzeige einzutragen.In a further embodiment, instead of displaying a center marker, it is also possible to enter a left marker 38 and a right marker 39 in the lane 30 for a route determined from the street map base. A corresponding representation is shown in FIG. Accordingly, it is also possible, both the center marker 26, for example, for a determined from the location of the road along with side markers 38, 39 for one of the Turned steering angle out certain road at the same time enter into the display.
In der Figur 4 ist ferner eine auch mit anderen Ausführungsbeispielen zusammen verwendbare Darstellung 40 eines Straßenverlaufs 41 gezeigt. Der Straßenverlauf 41 ist in Form einer Kartendarstellung bzw. eines kleinen Kartenausschnitts in der Anzeige dargestellt. Der Straßenverlauf 41 ist hierbei in Fahrtrichtung für einen bestimmten, über den aktuellen Sichtbereich des Fahrers hinausgehenden Abschnitt dargestellt. In einer bevorzugten Ausführungsform ist auch eine aktuelle Position 42 des Fahrzeugs in Bezug auf den Straßenverlauf 41 eingetragen. Neben einer Einblendung in die Anzeige 8 selbst ist es auch möglich, den Straßenverlauf in einer zusätzlichen Anzeige vorzusehen. Während z.B. die Nachtsichtdarstellung in einem Kombinationsinstrument vor dem Fahrer erfolgt, kann der Kartenausschnitt 40 in einer Mittelkonsolenanzeige dargestellt werden. In einer weiteren Ausführungsform ist es auch möglich, in der Kartendarstellung 40 jeweils die eingestellte Route von der aktuellen Position aus bis etwa lkm im Voraus anzuzeigen.
FIG. 4 also shows a depiction 40 of a road course 41 which can also be used together with other exemplary embodiments. The course of the road 41 is shown in the form of a map representation or a small map detail in the display. The course of the road 41 is represented here in the direction of travel for a specific section which extends beyond the driver's current field of vision. In a preferred embodiment, a current position 42 of the vehicle is registered in relation to the road course 41. In addition to a display in the display 8 itself, it is also possible to provide the road in an additional display. While e.g. the night view is done in a combination instrument in front of the driver, the map section 40 can be displayed in a center console display. In another embodiment, it is also possible to display in the map display 40 in each case the set route from the current position to about 1 km in advance.
