Abstract

The invention relates to a traffic light display, comprising a red, a yellow, and a green signal light ("traffic signal"), which are oriented opposite the driving direction of the traffic to be controlled, characterized by a sensor oriented opposite the driving direction, wherein said sensor detects a person located to the right of a vehicle as viewed in the driving direction and, in response thereto, modifies the lighting of the green signal light or causes a fourth signal light arranged adjacent to the green signal light to light up or flash.

Description

LICHTSIGNALANZEIGE MIT FUSSGÄNGERERKENNUNGSEINRICHTUNG  LIGHT SIGNAL INDICATOR WITH PEDESTRIAN DETECTION DEVICE
Die Erfindung betrifft eine Lichtsignalanzeige mit einem roten, einem gelben und einem grünen Signallicht („Ampel"), die gegen die Fahrtrichtung des zu regelnden Verkehrs weisend ausgerichtet sind. The invention relates to a light signal display with a red, a yellow and a green signal light ("traffic light"), which are oriented facing the direction of travel of the traffic to be regulated.
Im Straßenverkehr ist eine häufige Ursache von schwersten Verkehrsunfällen, denen Opfer Fußgänger, insbesondere aber Fahrradfahrer sind, das Übersehen dieser Personen bei dem Rechtsabbiegen eines Fahrzeugs: die zu Schaden kommende Person befindet sich im sog. „toten Winkel" des Fahrzeugs, wenn dieses an einer Ampel nach rechts abbiegt, und kollidiert mit dem Fahrzeug. In road traffic is a common cause of the most serious traffic accidents to which victims are pedestrians, but especially cyclists, the overlooking of these persons in the right turn of a vehicle: the person to be injured is in the so-called "blind spot" of the vehicle, if this at a Traffic light turns right, and collides with the vehicle.
Der Erfindung liegt die Aufgäbe zugrunde, eine Lichtsignalanzeige zu schaffen, die das Auftreten derartiger Unfälle vermeidet. The invention is based on the object to provide a light signal display that avoids the occurrence of such accidents.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass die Lichtsignalanzeige mit einem gegen die Fahrtrichtung ausgerichteten Sensor versehen ist, der eine in Fahrtrichtung gesehen rechts neben einem Kraftfahrzeug befindliche Person erkennt und darauf ansprechend das Leuchten des grünen Signallichts modifiziert oder das Aufleuchten oder Blinken eines zu dem kommenden Signallicht benachbart angeordneten vierten Signallichts bewirkt, wobei in Ländern mit Linksverkehr eine links neben dem Kraftfahrzeug befindliche Person erkennt. Bei dem Sensor kann es sich um einen Infrarot-Sensor handeln, alternativ kommt eine Kamera oder ein Radardetektor in Betracht. According to the invention, this object is achieved in that the light signal display is provided with an aligned against the direction of travel sensor recognizes a seen in the direction of travel right next to a motor vehicle person and responsively modified the lights of the green signal light or flashing or flashing one to the coming Signal light adjacent arranged fourth signal light causes, recognizes in countries with left-hand traffic, a person located on the left next to the motor vehicle. The sensor may be an infrared sensor, alternatively a camera or a radar detector may be considered.
Der geeignet auszurichtende Sensor erfasst den Raum (in Fahrtrichtung gesehen) rechts von den Fahrzeugen (häufig also den Radweg) und - bei Verwendung eines Infrarot-Sensors die von einer Person ausgehende, bei Annäherung an die Ampel zunehmende Wärmestrahlung. Bei Erkennen dieser von einer sich annähernden Person ausgehenden Wärmestrahlung, steuert der Sensor eine Einrichtung an, die eine Modifikation des Aufleuchtens des grünen Signallichts bewirkt oder aber ein viertes Signallicht zum Aufleuchten bringt, durch das der Fahrer des Fahrzeugs, neben dem sich der Fahrradfahrer befindet, auf das Erkennen einer Person rechts neben seinem Fahrzeug aufmerksam macht. The suitably aligned sensor detects the space (seen in the direction of travel) to the right of the vehicles (often so the bike path) and - when using an infrared sensor emanating from a person, increasing when approaching the traffic light heat radiation. Upon detection of this radiant heat emanating from an approaching person, the sensor actuates a device which effects a modification of the flare of the green signal light or illuminates a fourth signal light through which the driver of the vehicle beside which the cyclist is draws attention to the recognition of a person to the right of his vehicle.
Alternativ kann auch eine Kamera vorgesehen sein, die das von ihr aufgenommene Bild analysiert und feststellt, dass sich ein Objekt neben dem Fahrzeug (in Fahrtrichtung rechts gesehen) auf die Lichtsignalanzeige hin bewegt. Auch in diesem Fall wird das grüne Signallicht oder ein viertes, gesondertes Signallicht geeignet angesteuert und den Fahrer entsprechend warnen. Alternatively, a camera may also be provided which analyzes the image taken by it and determines that an object next to the vehicle (seen to the right in the direction of travel) is moving toward the light signal display. Also in this case, the green signal light or a fourth, separate signal light is suitably controlled and warn the driver accordingly.
Bevorzugt aber ist der Sensor als Radargerät ausgebildet. Dabei kann das Radargerät so ausgebildet sein, dass seine Auswerteelektronik die von dem Gerät ausgestrahlten und von dem Fahrradfahrer reflektierten Radarstrahlen erkennt. Preferably, however, the sensor is designed as a radar device. In this case, the radar device can be designed such that its transmitter detects the radiated from the device and reflected by the cyclist radar beams.
Da derartige Sensoren en kegelförmiges Feld erfassen, ist dafür Sorge zu tragen, dass die Lichtsignalanlage den Fahrer auch dann noch warnt, wenn die Person (etwa der Radfahrer) sich so nahe an dem Mast der Lichtsiganlanlage befindet, dass sie von dem an diesem hoch aufgehängten Sensor nicht mehr erfasst wird. Zu diesem Zweck kann eine Schaltung vorgesehen sein, die das Blinken oder Aufleuchten des Warnsignals über die Zeitdauer der Erfassung einer Person hinaus für einige Sekunden fortsetzt, bis gewährleistet ist, dass die erkannte Person den Gefahrenbereich auch tatsächlich verlassen hat. Bei der Bestimmung dieser Zeitdauer kann die festgestellte Annäherungsgeschwindigkeit der Person, insbesondere also des Radfahrers, berücksichtigt werden. Besonders bevorzugt ist eine Ausfuhrungsform, bei der der Sensor in die Ablaufsteuerung der Lichtsignalanlage integriert ist, etwa derart, dass ein die Kreuzung freigebendes Signal nur dann angezeigt wird, wenn sich keine Person (mehr) im Gefahrenbereich befindet. Since such sensors detect a conical field, care must be taken to ensure that the traffic light system warns the driver even if the person (such as the cyclist) is so close to the mast of the light plant that it is suspended from the one suspended therefrom Sensor is no longer detected. For this purpose, a circuit may be provided which continues the flashing or flashing of the warning signal beyond the period of detection of a person for a few seconds until it is ensured that the recognized person has actually left the danger zone. In determining this period of time, the ascertained approach speed of the person, in particular of the cyclist, can be taken into account. Particularly preferred is an embodiment in which the sensor is integrated into the flow control of the traffic signal system, such that a signal releasing the intersection is displayed only when no person (more) is in the danger zone.
Weiter wird vorgeschlagen, dass der Sensor in die Ablaufsteuerung der Lichtsignalanlage einbezogen ist, etwa derart, dass ein die Kreuzung freigebendes Signal nur dann angezeigt wird, wenn sich keine Person (mehr) im Gefahrenbereich befindet. It is further proposed that the sensor is included in the sequence control of the traffic signal system, such that a signal releasing the intersection is displayed only when no person is (anymore) in the danger zone.
