Abstract

The method of control of the illumination of a lateral lamp for the vehicle via a distance actuated sensor. This produces an output algorithm for the trajectory of an object lateral of the vehicle, to produce a collision likelihood value for control of the lamp.

Description

Die Erfindung betrifft ein Verfahren zur Steuerung der Ausleuchtung eines seitlichen Fahrbahnbereichs mittels eines Hilfsscheinwerfers für ein Fahrzeug. Fahrzeuge besitzen üblicherweise eine Scheinwerferanordnung mit einem Hauptscheinwerfer für Abblend- und Fernlicht. Zusätzlich ist es bekannt, einen Hilfsscheinwerfer zur Ausleuchtung eines seitlich bezüglich des Fahrzeugs gelegenen Bereichs vorzusehen. Mit Hilfe des Hilfsscheinwerfers soll ein am Fahrbahnrand der anderen Straßenseite gehender Fußgänger beleuchtet und damit besser erkennbar werden.The The invention relates to a method for controlling the illumination a side lane area by means of an auxiliary headlamp for a vehicle. Vehicles usually own a headlamp assembly with a main headlamp for dimming and high beam. additionally It is known, an auxiliary headlight for illuminating a side in terms of provided area of the vehicle. With the help of the auxiliary headlight should a pedestrian walking at the edge of the road on the other side of the street lights up and thus become more recognizable.

Aus der DE 196 31 151 A1 ist eine derartige Scheinwerferanordnung bekannt, bei der ein derartiger Hilfsscheinwerfer vorgesehen ist. Der Hilfsscheinwerfer dient insbesondere dazu, einen am Fahrbahnrand der anderen Straßenseite gehenden Fußgänger zu beleuchten und damit besser erkennbar zu machen. Er muss von Hand eingeschaltet werden. Zur Vermeidung einer Blendung des entgegenkommenden Fahrzeugs wird das Licht des Hilfsscheinwerfers gedämpft oder abgeschaltet, wenn ein Fahrzeug mit Beleuchtung entgegenkommt. Hierfür ist eine Sensorik vorgesehen, die das Licht des entgegenkommenden Fahrzeugs aufnimmt und über eine zusätzliche Steuereinrichtung den Hilfsscheinwerfer entsprechend verändert.From the DE 196 31 151 A1 Such a headlight assembly is known in which such auxiliary headlight is provided. The auxiliary headlight serves, in particular, to illuminate a pedestrian walking on the roadside edge of the other side of the road and thus make it easier to see. He must be turned on by hand. To avoid dazzling the oncoming vehicle, the light of the auxiliary headlight is attenuated or turned off when a vehicle comes to light. For this purpose, a sensor is provided which receives the light of the oncoming vehicle and changes the auxiliary headlight accordingly via an additional control device.

Damit aber ergibt sich ein besonderes Problem. Gerade in dem Augenblick, in dem durch eine mögliche, durch das entgegenkommende Fahrzeug hervorgerufene Blendung des Fahrers die Wahrnehmbarkeit des Fußgängers ohnehin reduziert ist, wird auch der Hilfsscheinwerfer praktisch unwirksam gemacht. Gegenüber konventionellen Fahrzeugen ohne einen derartigen Hilfsscheinwerfer ergibt sich damit keine funktionelle Verbesserung. Im Gegenteil könnte man sogar von einer Verschlechterung sprechen. Der Fahrer des Fahrzeugs mit Hilfsscheinwerfer verlässt sich auf dessen Wirkung. Nimmt er einen eigentlich vorhanden Fußgänger nicht wahr, sieht er die Ursache nicht in der gezielten Ausschaltung des Hilfsscheinwerfers, sondern nimmt irrtümlich an, es sei tatsächlich kein Fußgänger vorhanden.In order to but there is a special problem. Just at the moment, in that by a possible, caused by the oncoming vehicle dazzling the Driver's perceptibility of the pedestrian is reduced anyway, will also the auxiliary headlights made practically ineffective. Compared to conventional Vehicles without such auxiliary headlights results from it no functional improvement. On the contrary, one could even of a deterioration speak. The driver of the vehicle with auxiliary headlight relies on its effect. Does he not take a pedestrian present? True, he does not see the cause in the targeted elimination of the auxiliary headlight, but mistakenly takes it was actually no pedestrian available.

Ziel der Erfindung ist es daher, eine Scheinwerferanordnung für ein Fahrzeug anzugeben, mit der ein Fußgänger auch an der gegenüberliegenden Fahrbahnseite auch dann erkannt werden kann, wenn ein möglicherweise blendendes Fahrzeug entgegenkommt.aim The invention is therefore a headlight assembly for a vehicle indicate with which a pedestrian too on the opposite side of the road can be detected even if a possibly dazzling vehicle accommodates.

Die Lösung des Problems wird mit den im Patentanspruch 1 angegebenen Mitteln erreicht.The solution The problem is solved with the means specified in claim 1 reached.

Die Erfindung stellt ein System der aktiven Sicherheit dar, das auf eine verbesserte Sichtbarkeit des Fußgängers für den Fahrer abzielt unabhängig von einer evtl. Blendung durch ein entgegenkommendes Fahrzeug.The Invention represents an active safety system based on Improved visibility of the pedestrian for the driver is aimed independently a possible dazzling by an oncoming vehicle.

Mit Hilfe von Umfeldsensoren lassen sich Fußgänger im Umfeld des Fahrzeuges als Objekte erkennen und als Fußgänger klassifizieren. Es können hierbei verschiedene Umfeldsensortechnologien verwendet werden: Videobasierte Systeme mit nachgeschalteter Bildverarbeitung, Nachtsichtsysteme im nahen und fernen Infrarot mit nachgeschalteter Bildverarbeitung, oder abstandsgebende Systeme wie Radar, Laserscanner oder Lidar. Zudem sind Kombinationen zweier oder mehrerer dieser Sensoren (sog. sensorfusionierte Systeme) möglich.With Help from environmental sensors can be pedestrian in the environment of the vehicle recognize as objects and classify them as pedestrians. It can different environment sensing technologies are used: Video-based systems with downstream image processing, night vision systems in the near and far infrared with downstream image processing, or distance-giving systems such as radar, laser scanner or lidar. In addition, combinations of two or more of these sensors (so-called. sensor-fused systems) possible.

Algorithmen zur Erkennung und Prädiktion von Unfällen, die unter der Bezeichnung Situationsinterpreter bekannt sind, ermöglichen die Wahrscheinlichkeit für den Unfall mit einem Fußgänger sowie die Dauer bis zum Unfall (TTC = Time to Collision) zu ermitteln. Dazu wird das Verhalten des Fußgängers auf Basis seiner bisherigen Trajektorie für die Zukunft prädiziert und mit der Bewegung des eigenen Fahrzeuges korreliert.algorithms for the detection and prediction of accidents which are known as situation interpreter allow the probability for the accident with a pedestrian as well determine the time to collision (TTC = time to collision). This is based on the behavior of the pedestrian his previous trajectory for the future predicts and correlated with the movement of one's own vehicle.

Als Hilfsscheinwerfer können u. a. ein schwenk- und fokussierbarer Scheinwerfer oder ein Pixelscheinwerfer verwendet werden. Beim Pixellichtscheinwerfer handelt es sich um eine an sich bekannte Scheinwerfertechnologie, die auf dem sogenannten DMD-Prinzip (Digital Micromirror Device) basiert. Über steuerbare Mikrospiegel, die vorzugsweise im Hauptscheinwerfer oder, wenn dieser vollständig in DMD-Technik aufgebaut ist, innerhalb des Scheinwerfers angeordnet sind, kann eine beliebige Steuerung/Aufspaltung/Fokussierung/Ausrichtung des von einer Lampe stammenden Lichtes und damit eine punktgenaue Lichtverteilung auf einen gefährdeten Fußgänger erreicht werden. Die DMD-Technik ermöglicht auch, mit dem Hauptscheinwerfer ein blendfreies Dauerfernlicht zu erzeugen, bei dem der Bereich des Gesichts eines entgegenkommenden Verkehrsteilnehmers ausgeblendet wird.When Auxiliary headlights can u. a. a swivel and focus headlight or a pixel headlight be used. The pixel light is about a known headlight technology, which is based on the so-called DMD principle (Digital Micromirror Device) based. About controllable Micromirror, preferably in the headlight or, if this Completely built in DMD technology is located within the headlamp, any control / splitting / focusing / alignment of the from a lamp-originating light and thus a pinpoint light distribution on a vulnerable Pedestrians reached become. The DMD technology allows also, with the main headlamp to a glare-free Dauerfernlicht generate, where the area of the face of an oncoming traffic participant is hidden.

Vorteilhafte Ausgestaltungen der Erfindung sind in den weiteren Patentansprüchen angegeben und werden an Hand des folgenden Ausführungsbeispiels näher erläutert.advantageous Embodiments of the invention are specified in the further claims and will be explained in more detail with reference to the following embodiment.

Die Erfindung wird nun anhand von Ausführungsbeispielen unter Hinweis auf die beigefügten Zeichnungen beschrieben. InThe Invention will now be described with reference to exemplary embodiments to the attached drawings described. In

2 ein Lichtverteilungsmuster durch die Frontlampen vor dem Fahrzeug aus Sicht des Fahrers gezeigt. 2 a light distribution pattern through the front lamps in front of the vehicle as seen by the driver.

Das erfindungsgemäße Scheinwerfersystem besteht aus folgenden Komponenten (siehe 1): einem Pixellichtscheinwerfer 1, einem abstandsgebenden Sensor 2 wie Radar, Laserscanner, Lidar, einem fußgängerklassifizierenden Sensor 3 (Video mit Bildverarbeitung, IR-Sensor mit Bildverarbeitung) sowie einem Steuergerät 4 mit Crash-Prediciton-Algorithmus.The headlamp system according to the invention consists of the following components (see 1 ): a pixel light 1, a distance sensor 2 such as radar, laser scanner, lidar, a pedestrian classifying sensor 3 (video with image processing, IR sensor with image processing) and a controller 4 with crash prediction algorithm.

Über den abstandsgebenden Sensor 2 und den fußgängerklassifizierenden Sensor 3 werden Fußgänger erkannt und klassifiziert. Der abstandsgebende Sensor detektiert Objekte im Fahrzeugumfeld und ermöglicht es, über die Abstands- und Bewegungsmessung des Objekts die Trajektorie (Bewegungsrichtung und -ort) des Objektes zu bestimmen. Mit dem klassifizierenden Sensor 3 erfolgt eine Klassifikation, ob es sich bei dem Objekt um einen Fußgänger handelt. Verwendbar sind hier Videosensoren im sichtbaren und/oder infraroten Bereich, wobei im letzteren Falle zum einen das Bild im nahen IR (NIR = Near Infra Red) oder auch im fernen IR (FIR = Far Infra Red = Wärmeabstrahlung) aufgenommen werden kann. Die Klassifikation erfolgt durch Mustererkennungsalgorithmen.On the distance sensor 2 and the pedestrian classifying sensor 3, pedestrians are recognized and classified. The distance sensor detects objects in the vehicle environment and allows it, about the distance and movement measurement of the object, the trajectory (direction of movement and -ort) of the object. With the classifying sensor 3, a classification is made as to whether the object is a Pedestrian acts. Useful here are video sensors in the visible and / or infrared Range, in the latter case, on the one hand, the image in the near IR (NIR = Near Infra Red) or in the far IR (FIR = Far Infra Red = Heat radiation) can be included. The classification is done by pattern recognition algorithms.

Über einen Situationsinterpreter wird die Wahrscheinlichkeit für einen Unfall mit dem Fußgänger sowie die Dauer bis zum Unfall (TTC = Time to Collision) ermittelt. Dazu wird das Verhalten des Fußgängers auf Basis seiner bisherigen Trajektorie für die Zukunft prädiziert und mit der prädizierten Bewegung des eigenen Fahrzeuges korreliert.About one Situation interpreter will increase the likelihood of one Accident with the pedestrian as well the duration until the accident (TTC = Time to Collision) determined. To is the behavior of the pedestrian Based on his previous trajectory predicted for the future and with the predicated Movement of the own vehicle correlates.

Ist eine definierte Unfallwahrscheinlichkeit und/oder TTC gegeben, so erfolgt eine gezielte Ansteuerung des Pixellichtes in dem Sinne, dass der Fußgänger durch einen Teil der lenkbaren Strahlen des Pixellichtscheinwerfers ausgeleuchtet wird (siehe 2). Dabei kann zum einen der bisher unbeleuchtete Fußgänger nun beleuchtet, zum anderen die Ausleuchtung des Fußgängers durch eine Steigerung der Intensität weiter erhöht werden.If a defined accident probability and / or TTC is given, a targeted control of the pixel light takes place in the sense that the pedestrian is illuminated by a part of the steerable beams of the pixel light headlight (see 2 ). In this case, on the one hand the previously unlit pedestrian can now be illuminated, on the other hand the illumination of the pedestrian can be further increased by increasing the intensity.

Ergänzend ist es möglich, die Bewegung des Fußgängers mittels der Sensoren 2 und 3 zu verfolgen und ihn begleitend mit seiner Bewegung auszuleuchten.Complementary it is possible the movement of the pedestrian by means of to track the sensors 2 and 3 and accompanying it with his To illuminate movement.

An Hand von 2 ist die prinzipielle Funktionsweise des erfindungsgemäßen Verfahrens an Hand einer Scheinwerferanordnung dargestellt.Based on 2 is the basic operation of the method according to the invention shown with reference to a headlamp assembly.

Im Falle, dass vom Crash-Prediction-Algorithmus keine hinreichende Unfallwahrscheinlichkeit zwischen dem Fahrzeug 5 und dem Fußgänger 6 erkannt wird, erfolgt keine zusätzliche Ausleuchtung des detektierten und klassifizierten Fußgängers (linkes Bild).in the Case that from the crash prediction algorithm is not sufficient Accident probability between the vehicle 5 and the pedestrian 6 detected will be, there is no additional Illumination of the detected and classified pedestrian (left Image).

Falls eine hinreichende Unfallwahrscheinlichkeit vom Crash-Prediction-Algorithmus errechnet wird, erfolgt eine zusätzliche Ausleuchtung des Fußgängers mit Hilfe des Pixellichtscheinwerfers (rechtes Bild).If a reasonable accident probability from the crash prediction algorithm is calculated, there is an additional Illumination of the pedestrian with Help of pixel light spotlight (right image).

Durch eine verbesserte Ausleuchtung von schlecht sichtbaren und unbeleuchteten Fußgängern v.a. bei Dunkelheit ergibt sich ein verbesserter Schutz von Fußgängern im Straßenverkehr. Der Fahrer wird durch das System auf den Fußgänger, der Fußgänger wiederum durch die durchgeführte Blendung auf das Fahrzeug und damit auf die Unfallgefahr aufmerksam gemacht.By an improved illumination of poorly visible and unlit Pedestrians v.a. in the dark there is an improved protection of pedestrians in the Road traffic. The driver is turned by the system on the pedestrian, the pedestrian through the performed Glare on the vehicle and thus aware of the risk of accidents made.
