Die vorliegende Erfindung betrifft ein Verfahren zum Unterstützen eines Fahrers eines Fahrzeugs. Ferner betrifft die Erfindung ein Fahrerassistenzsystem für ein Fahrzeug mit einer Umfelderfassungsvorrichtung zum Detektieren von Objekten im Umfeld des Fahrzeugs, einer mit der Umfelderfassungsvorrichtung gekoppelten Analysevorrichtung, mittels welcher bestimmbar ist, ob ein detektiertes Objekt eine Kollisionsgefahr für das Fahrzeug darstellt, und einer mit der Analysevorrichtung gekoppelten Steuervorrichtung, mittels welcher eine veränderbare Lichtemission eines Scheinwerfersystems des Fahrzeugs erzeugbar ist.The The present invention relates to a method for assisting a driver of a vehicle. Furthermore, the invention relates to a Driver assistance system for a vehicle with an environment detection device for detecting objects around the vehicle, one with the environment detecting device coupled analysis device, by means of which can be determined whether a detected object is a danger of collision represents for the vehicle, and one with the analysis device coupled control device, by means of which a variable Light emission of a headlamp system of the vehicle generated is.
Es ist bekannt Fahrzeuge mit verschiedenen Fahrerassistenzsystemen auszustatten, welche den Fahrer beim Fahren des Fahrzeugs unterstützen. Solche Fahrerassistenzsysteme sollen insbesondere das Umfeld des Fahrzeugs erfassen und interpretieren, um gefährliche Situationen, insbesondere solche, die mit einer Kollisionsgefahr verbunden sind, frühzeitig zu erkennen und den Fahrer bei seinen Fahrmanövern zu unterstützen. Durch Fahrerassistenzsysteme soll der Fahrer dabei unterstützt werden, Kollisionen nach Möglichkeit ganz zu vermeiden oder zumindest die Folgen einer Kollision so gering wie möglich zu halten.It is known vehicles with different driver assistance systems equip the driver while driving the vehicle. Such Driver assistance systems are intended in particular the environment of the vehicle capture and interpret dangerous situations, especially those that are associated with a risk of collision, early to recognize and assist the driver in his driving maneuvers. Driver assistance systems are intended to assist the driver be avoided, if possible, or completely avoid collisions at least the consequences of a collision as low as possible to keep.
Es sind beispielsweise Kollisionswarnsysteme bekannt, die Objekte im Umfeld des Fahrzeugs detektieren und den Fahrer auf solche Objekte hinweisen, die eine Kollisionsgefahr darstellen. Derartige Systeme können insbesondere den Fahrer bei Nachtfahrten unterstützen, da in diesem Fall die Ausleuchtung der Umgebung des Fahrzeugs durch das Fahrzeugscheinwerfersystem geringer ist als bei Tagfahrten. Für Nachtfahrten ist beispielsweise ein System bekannt, bei dem auf einem Display im Innenraum des Fahrzeugs oder über ein Head-up Display Objekte visualisiert werden, die sich in einer Entfernung vor dem Fahrzeug befinden, welche die Reichweite des Scheinwerfersystems des Fahrzeugs übersteigt.It For example, collision warning systems are known, the objects in the Detect environment of the vehicle and the driver on such objects indicate a risk of collision. Such systems in particular, can assist the driver in driving at night, in this case, the illumination of the environment of the vehicle through The vehicle headlamp system is lower than during day trips. For night driving, for example, a system is known when on a display in the interior of the vehicle or over A head-up display visualizes objects that are in one Distance in front of the vehicle, which is the range of the Headlamp system of the vehicle exceeds.

Es ist die Aufgabe der vorliegenden Erfindung, das Verfahren und das Fahrerassistenzsystem der eingangs genannten Art so zu verbessern, dass die Wahrscheinlichkeit einer Kollision verringert wird.It is the object of the present invention, the method and the Driver assistance system of the type mentioned so to improve that the probability of a collision is reduced.
Erfindungsgemäß wird diese Aufgabe durch ein Verfahren mit den Merkmalen des Anspruchs 1 bzw. ein Verfahren mit den Merkmalen des Anspruchs 16 sowie ein Fahrerassistenzsystem mit den Merkmalen des Anspruchs 11 gelöst. Vorteilhafte Aus- und Weiterbildungen ergeben sich aus den abhängigen Ansprüchen.According to the invention this object by a method having the features of the claim 1 or a method with the features of claim 16 and a Driver assistance system solved with the features of claim 11. Advantageous training and further education emerge from the dependent Claims.
Das erfindungsgemäße Verfahren ist dadurch gekennzeichnet, dass Objekte im Umfeld des Fahrzeugs detektiert werden, analysiert wird, ob ein detektiertes Objekt eine Kollisionsgefahr für das Fahrzeug darstellt, und, wenn ein Objekt eine Kollisionsgefahr für das Fahrzeug darstellt, eine Lichtemission erzeugt wird, die dem Fahrer eine Fahrtrichtung zur Verringerung der Kollisionsgefahr weist.The method according to the invention is characterized that objects are detected in the environment of the vehicle analyzed Whether a detected object is a danger of collision for represents the vehicle, and if an object is a danger of collision represents for the vehicle, generates a light emission will give the driver a direction of travel to reduce the risk of collision has.
Unter einem Objekt wird im Sinne der Erfindung eine beliebige Gefahrenstelle verstanden, die dazu führen kann, dass das Fahrzeug mit dem Objekt oder einem anderen Objekt kollidieren kann. Das Objekt kann beispielsweise ein anderer Verkehrsteilnehmer, wie ein anderes Fahrzeug, insbesondere ein stehendes Fahrzeug oder ein Fahrzeug mit einer sehr viel geringeren Geschwindigkeit als das eigene Fahrzeug, ein Radfahrer oder ein Fußgänger sein. Ferner kann das Objekt auch eine mit zu hoher Geschwindigkeit angefahrene Kurve sein. Ob das Objekt zu einer Kollisionsgefahr für das Fahrzeug führt, wird dabei in Abhängigkeit von der Situation bewertet, in der sich das Fahrzeug befindet. Dabei wird insbesondere die Bewegungsrichtung und -geschwindigkeit des Fahrzeugs sowie die Bewegungsrichtung und -geschwindigkeit des detektierten Objekts berücksichtigt.Under An object becomes within the meaning of the invention any hazard understood, which can lead to the vehicle with can collide with the object or another object. The object For example, another road user may be like another Vehicle, in particular a stationary vehicle or a vehicle at a much slower speed than your own vehicle, be a cyclist or a pedestrian. Further The object may also be driven too fast Be a curve. Whether the object is a danger of collision for the vehicle leads is dependent on it assessed by the situation in which the vehicle is located. there In particular, the direction of movement and speed of the Vehicle as well as the direction of movement and speed of the detected Object considered.
Gemäß einer bevorzugten Weiterbildung des erfindungsgemäßen Verfahrens wird die Lichtemission in einem Bereich einer Fahrtrichtung erhöht, die zu einer Verringerung der Kollisionsgefahr führt. Falls beispielsweise vor der Detektion der Kollisionsgefahr Licht für ein herkömmliches Abblendendlicht von dem Scheinwerfersystem des Fahrzeugsystems emittiert wird, wird eine zusätzliche Lichtemission dem Abblendlicht überlagert und die Lichtemission in einer Richtung erhöht, in den der Fahrer das Fahrzeug lenken sollte, um die Kollisionsgefahr zu verringern. Falls vor der Detektion der Kollisionsgefahr kein Licht vom Scheinwerfersystem des Fahrzeugs emittiert wurde, kann bei dem erfindungsgemäßen Verfahren die Lichtemission nur entlang einer Linie oder entlang eines sehr schmalen Lichtkegels auf der Fahrbahn erzeugt werden, die einen Fahrweg weist, welcher die mögliche Kollision vermeidet oder die Folgen einer etwaigen Kollision so gering wie möglich hält. Bei dem erfindungsgemäßen Verfahren wird somit ein so genanntes Fluchtlicht bereitgestellt. Bei dem erfindungsgemäßen Verfahren wird nicht wie bei bekannten Verfahren die Gefahrenstelle ausgeleuchtet. Eine solche Ausleuchtung weist dem Fahrer nämlich gerade nicht eine Fahrtrichtung zur Verringerung der Kollisionsgefahr, sondern eine Fahrtrichtung, bei der die Kollisionsgefahr erhöht ist.According to one preferred development of the invention Method, the light emission in a range of a direction of travel increases, which reduces the risk of collision leads. For example, if before the detection of collision danger light for a conventional low beam of the Headlight system of the vehicle system is emitted, is a additional light emission superimposed on the low beam and the light emission increases in one direction, in the the driver should steer the vehicle to avoid the risk of collision reduce. If there is no light before detecting the risk of collision emitted by the headlamp system of the vehicle can be found in the inventive method, the light emission only along a line or along a very narrow cone of light be generated on the road, which has a guideway, which avoids the possible collision or the consequences of a collision any collision as low as possible. In the method according to the invention thus becomes provided a so-called flight light. In the inventive The method is not as in known methods the danger point illuminated. Such illumination indicates the driver namely just not a direction of travel to reduce the risk of collision, but a direction of travel, which increases the risk of collision is.
Vorteilhaft an der von dem erfindungsgemäßen Verfahren bereitgestellten Lichtemission ist, dass der Fahrer nur der erhöhten Lichtemission bei dem Fahrmanöver zur Vermeidung der Kollision folgen muss. Insbesondere in einer solchen kritischen Fahrsituation ist es nämlich nachteilig, wenn der Fahrer Zusatzinformationen, die nur über Displays im Fahrzeug oder ein Head-up Display dargestellt werden, erfassen und kognitiv auswerten muss. Die von dem erfindungsgemäßen Verfahren bereitgestellte Unterstützung des Fahrers kann dieser somit sehr einfach, intuitiv und schnell umsetzen.Advantageous at the provided by the method according to the invention Light emission is that the driver only the increased light emission Follow the maneuver to avoid the collision got to. Especially in such a critical driving situation it is disadvantageous if the driver has additional information, the only on displays in the vehicle or a head-up display be displayed, recorded and evaluated cognitively. The one of the Support provided according to the invention The driver can thus very easily, intuitively and quickly implement.
Gemäß einer weiteren Ausgestaltung des erfindungsgemäßen Verfahrens wird bei einem Überholvorgang ein zu überholendes Fahrzeug neben dem eigenen Fahrzeug und ein entgegenkommendes Fahrzeug vor dem eigenen Fahrzeug detektiert. Erfindungsgemäß wird in diesem Fall vor dem eigenen Fahrzeug ein Lichtzeichen auf die Fahrbahn projiziert, welches dem Fahrer einer Unterstützung zum Abschließen des Überholvorgangs bietet. Falls beispielsweise die Analyse des Umfelds des Fahrzeugs beim Überholvorgang, d. h. insbesondere die zeitliche Entwicklung der relativen Abstände des eigenen Fahrzeugs zu dem zu überholenden Fahrzeug und zu dem entgegenkommenden Fahrzeug ergibt, dass der Überholvorgang abgebrochen werden sollte, wird bei dem erfindungsgemäßen Verfahren vor dem eigenen Fahrzeug ein Lichtzeichen auf die Fahrbahn projiziert, welches einen Abbruch des Überholvorgangs anzeigt. Beispielsweise kann in diesem Fall als Lichtzeichen ein Pfeil auf die Fahrbahn projiziert werden, der auf das zu überholende Fahrzeug zeigt.According to one further embodiment of the method according to the invention becomes an overtaking in an overtaking Vehicle next to the own vehicle and an oncoming vehicle detected in front of your own vehicle. According to the invention in this case in front of your own vehicle a light on the Lane projects, giving the driver a support to complete the overtaking process. If for example, the analysis of the environment of the vehicle during the overtaking process, d. H. in particular the temporal evolution of the relative distances of the own vehicle to the vehicle to be overtaken and to the oncoming vehicle shows that the overtaking process should be canceled is in the inventive Procedure in front of one's own vehicle projecting a light signal onto the roadway, which indicates a cancellation of the overtaking process. For example can in this case as a light sign an arrow on the road be projected onto the vehicle to be overtaken shows.
Falls sich aus der Analyse des Überholvorgangs ergibt, dass der Fahrer das Fahrzeug beschleunigen sollte, wird vor dem eigenen Fahrzeug ein Lichtzeichen auf die Fahrbahn projiziert, das anzeigt, dass zum Abschluss des Überholvorgangs eine weitere Beschleunigung erforderlich ist.If the analysis of the overtaking process shows that the Driver should accelerate the vehicle, in front of the own vehicle Light signals projected onto the roadway, indicating that the Completion of the overtaking process further acceleration is required.
Des Weiteren können während des Überholvorgangs Lichtzeichen auf die Fahrbahn projiziert werden, die anzeigen, wann der Überholvorgang durch eine Veränderung der Fahrtrichtung dadurch abgeschlossen werden kann, dass das eigene Fahrzeug in eine Position vor das überholte Fahrzeug fährt. In diesem Fall kann beispielsweise als Lichtzeichen ein Pfeil auf die Fahrbahn projiziert werden, der in Richtung einer Position des eigenen Fahrzeugs vor das überholte Fahrzeug zeigt.Of Further can during the overtaking process Light signals are projected onto the roadway, indicating when the overtaking process by changing the Driving direction can be completed by that own Vehicle moves to a position in front of the outdated vehicle. In this case, for example, as a light sign on an arrow the roadway projected towards a position of the road own vehicle in front of the reconditioned vehicle shows.
Des Weiteren können bei dem Überholvorgang die empfohlenen Fahrmanöver, d. h. ein Abbruch des Überholvorgangs, eine Beschleunigung des Fahrzeugs oder ein Lenken des Fahrzeugs vor das überholte Fahrzeug farblich codiert werden, damit der Fahrer das empfohlene Fahrmanöver noch leichter erfassen kann.Of Further, in the overtaking the recommended Driving maneuvers, d. H. a termination of the overtaking process, an acceleration of the vehicle or a steering of the vehicle be color coded in front of the outdated vehicle so that the driver can more easily grasp the recommended driving maneuver can.
Gemäß einer Weiterbildung des erfindungsgemäßen Verfahrens werden auf die Fahrbahn Lichtzeichen projiziert, die den Abstand zu dem Objekt anzeigen, zu dem die Kollisionsgefahr besteht. Beispielsweise können senkrecht zur Fahrtrichtung Balken auf die Fahrbahn projiziert werden, deren Abstand ein Maß für den Abstand zu dem Objekt ist.According to one Further development of the method according to the invention are projected onto the roadway light signs that indicate the distance to the object to which the risk of collision exists. For example can be perpendicular to the direction of travel beams on the carriageway be projected whose distance is a measure of the Distance to the object is.
Gemäß einer weiteren Ausgestaltung des erfindungsgemäßen Verfahrens wird eine weitere Lichtemission im Inneren des Fahrzeugs erzeugt, die von der Position des Fahrers aus die Richtung des Objekts und/oder die Fahrtrichtung zur Verringerung der Kollisionsgefahr anzeigt.According to one further embodiment of the method according to the invention another light emission is generated inside the vehicle, from the position of the driver from the direction of the object and / or indicates the direction of travel to reduce the risk of collision.
Das erfindungsgemäße Fahrerassistenzsystem ist dadurch gekennzeichnet, dass mittels der Steuervorrichtung die Lichtemission des Scheinwerfersystems so erzeugbar ist, dass dem Fahrer durch die Lichtemission eine Fahrtrichtung zur Verringerung der Kollisionsgefahr gewiesen wird, wenn mittels der Analysevorrichtung bestimmt wurde, dass ein Objekt eine Kollisionsgefahr für das Fahrzeug darstellt.The inventive driver assistance system is characterized characterized in that by means of the control device, the light emission the headlight system is generated so that the driver through the Light emission one direction of travel to reduce the risk of collision when determined by the analyzer, that an object represents a risk of collision for the vehicle.
Das erfindungsgemäße Fahrerassistenzsystem weist dieselben Vorteile auf, wie das vorstehend beschriebene erfindungsgemäße Verfahren. Mittels des Fahrerassistenzsystems ist es insbesondere möglich, durch die Lichtemission des Scheinwerfersystems des Fahrzeugs dem Fahrer eine Fahrtrichtung zu weisen, der eine Kollision vermeidet oder die Folgen einer Kollision verringert.The driver assistance system according to the invention has the same advantages as the method according to the invention described above. By means of the driver assistance system, it is in particular possible by the light emission of the headlight system of the vehicle, the driver a driving line tion, which avoids a collision or reduces the consequences of a collision.
Die Umfelderfassungsvorrichtung des erfindungsgemäßen Fahrerassistenzsystems kann beispielsweise einen Radarsensor, einen Ultraschallsensor, einen optischen Sensor und/oder eine Kamera umfassen. Bei dem optischen Sensor kann es sich insbesondere um einen optischen Abstandsmesser handeln, der unter der Bezeichnung LIDAR(Light Detection and Ranging)-Sensor bekannt ist.The Environment detecting device of the invention Driver assistance system, for example, a radar sensor, a Ultrasonic sensor, an optical sensor and / or a camera include. The optical sensor may in particular be an optical Distance meter act under the name LIDAR (Light Detection and Ranging) sensor is known.
Gemäß einer Weiterbildung des erfindungsgemäßen Fahrerassistenzsystems ist eine weitere Lichtquelle im Inneren des Fahrzeugs angeordnet, deren Lichtemission so erzeugbar ist, dass sie von der Position des Fahrers aus die Richtung des Objekts und/oder die Richtung der Fahrtrichtung zur Verringerung der Kollisionsgefahr weist. Die weitere Lichtquelle kann insbesondere mehrere in Fahrtrichtung vor der Position des Fahrers positionierte lichtemittierende Dioden umfassen. Des Weiteren kann die weitere Lichtquelle einen Projektor umfassen, mit dem Licht auf eine in oder auf der Windschutzscheibe des Fahrzeugs angeordneten Reflexionsfolie projizierbar ist, um die Richtung des Objekts und/oder die Fahrtrichtung zur Verringerung der Kollisionsgefahr hervorzuheben.According to one Further development of the driver assistance system according to the invention is another light source arranged inside the vehicle, whose Light emission can be generated so that it depends on the position of the driver from the direction of the object and / or the direction of the direction of travel to reduce the risk of collision points. The other light source can in particular several in the direction of travel before the position of Driver positioned light emitting diodes include. Furthermore For example, the other light source may include a projector with the light arranged on a in or on the windshield of the vehicle Reflection film is projected to the direction of the object and / or highlight the direction of travel to reduce the risk of collision.
Gemäß einem weiteren Aspekt der Erfindung wird ein Verfahren zum Unterstützen eines Fahrers eines Fahrzeugs bereitgestellt, bei dem die Sollfahrspur einer Fahrbahn vor dem Fahrzeug erfasst wird und die Lichtemission des Fahrzeugs in Richtung der Fahrbahn so gesteuert wird, dass die Sollfahrspur unabhängig von der Position und/oder Ausrichtung des Fahrzeugs relativ zur Fahrbahn auf die Fahrbahn projiziert wird. Durch die Lichtemission des Fahrzeugs wird dem Fahrer somit eine optimale Fahrspur angezeigt, welcher er beim Befahren der Fahrbahn folgen sollte. Auch durch dieses Verfahren wird die Gefahr einer Kollision des Fahrzeugs mit anderen Objekten verringert, da der Fahrer unterstützt wird, nicht von der optimalen Fahrspur abzukommen. Insbesondere unbeabsichtigte Spurwechsel führen nämlich vielfach zu Kollisionen mit anderen Fahrzeugen oder Objekten neben der Fahrbahn. Das Objekt, welches bei dieser Ausgestaltung des Verfahrens im Umfeld des Fahrzeugs detektiert wird, ist somit die Fahrbahn vor dem Fahrzeug. Die Kollisionsgefahr wird durch ein Verlassen der Fahrspur vor dem Fahrzeug hervorgerufen. Auch die Projektion der Sollfahrspur gibt somit eine Fahrtrichtung vor, die zu einer Verringerung der Kollisionsgefahr führt.According to one Another aspect of the invention is a method of assisting provided by a driver of a vehicle, in which the desired lane a roadway in front of the vehicle is detected and the light emission the vehicle is controlled in the direction of the road so that the Target lane regardless of position and / or orientation of the vehicle is projected onto the roadway relative to the roadway. The light emission of the vehicle thus becomes a driver optimal lane, which he when driving on the road should follow. Also by this method is the danger of Collision of the vehicle with other objects is reduced because of the Driver is supported, not by the optimal lane come off. In particular, unintentional lane changes lead namely often to collisions with other vehicles or objects in addition the roadway. The object, which in this embodiment of the method is detected in the environment of the vehicle, so is the road in front of the vehicle. The danger of collision is caused by leaving caused the lane in front of the vehicle. Also the projection the target lane thus indicates a direction of travel, which leads to a reduction the danger of collision leads.

Bezug zu
Eine
häufige Ursache für Unfälle bei Nacht
ist das seitliche Abkommen von der Fahrbahn durch schlechte Sicht
oder Müdigkeit. Um solche Unfälle zu vermeiden,
sind Spurhalte- und Kurvenassistenten bekannt, die den Fahrer bei
Dunkelheit und Dämmerung unterstützen, die richtige
Fahrspur zu halten und die Kurve ideal zu durchfahren.In reference to
A frequent cause of accidents at night is the lateral agreement of the roadway due to poor visibility or fatigue. In order to avoid such accidents, lane keeping and cornering assistants are known, which assist the driver in darkness and twilight to keep the correct lane and to drive through the curve ideally.
