Abstract
Die Erfindung stellt ein Verfahren zum Ansteuern eines hochauflösenden Scheinwerfers mit den folgenden Merkmalen bereit: Auf mindestens ein bestimmtes Eingangssignal hin wird selbsttätig eine vorgegebene Lichtverteilung des Scheinwerfers (20) aktiviert, und sobald ein Steuergerät (14) mit Videoverarbeitungsfunktion einsatzbereit ist, wird der Scheinwerfer (20) mittels des Steuergerätes (14) angesteuert.Die Erfindung stellt ferner einen entsprechenden Scheinwerfer, ein entsprechendes Computerprogramm sowie ein entsprechendes maschinenlesbares Speichermedium bereit.The invention provides a method for controlling a high-resolution headlight with the following features: a specified light distribution of the headlight (20) is automatically activated in response to at least one specific input signal, and as soon as a control unit (14) with a video processing function is ready for use, the headlight ( 20) by means of the control unit (14). The invention also provides a corresponding headlight, a corresponding computer program and a corresponding machine-readable storage medium.
Description
Die vorliegende Erfindung betrifft ein Verfahren zum Ansteuern eines hochauflösenden Scheinwerfers. Die vorliegende Erfindung betrifft darüber hinaus einen entsprechenden Scheinwerfer, ein entsprechendes Computerprogramm sowie ein entsprechendes maschinenlesbares Speichermedium.The present invention relates to a method for controlling a high-resolution headlight. The present invention also relates to a corresponding headlight, a corresponding computer program and a corresponding machine-readable storage medium.
Stand der TechnikState of the art
Matrix-Scheinwerfer handelsüblicher Premium-Fahrzeuge erlauben zur blendfreien Segmentierung des Fernlichtkegels die getrennte Ansteuerung von bis zu 84 in einem Raster angeordneter Segmente. Die Steuerbefehle zum Ein- und Ausschalten verschiedener Lichtfunktionen werden hierbei üblicherweise im zentralen Karosseriesteuergerät (body control module, BCM) erzeugt und über einen Feldbus an das Scheinwerfer-Steuergerät (frontlight control module, FCM) übertragen.Matrix headlights of commercially available premium vehicles allow the separate control of up to 84 segments arranged in a grid for glare-free segmentation of the high beam. The control commands for switching various light functions on and off are usually generated in the central body control module (BCM) and transmitted to the headlight control unit (frontlight control module, FCM) via a fieldbus.
Eine Steuerungsvorrichtung gemäß
Bekannt sind ferner Lichtquellen mit weitaus mehr Segmenten. Derart hochauflösende Scheinwerfersysteme stellen besondere Anforderungen an ihre Ansteuerung, die in der Regel die Integration eines Steuergerätes mit Videoverarbeitungsfunktionen (pixel control module, PCM) bedingen. Abhängig von den internen Datenschnittstellen des Fahrzeuges kann ein solches PCM beispielsweise Videodatenströme von einem Kamerasystem oder einem Fahrerassistenzsystem mit Sensordatenfusion verarbeiten. Derlei Steuergeräte benötigen mitunter mehr als 1500 Millisekunden bis zur vollständigen Betriebsbereitschaft.Light sources with far more segments are also known. Such high-resolution headlight systems place special demands on their control, which usually require the integration of a control device with video processing functions (pixel control module, PCM). Depending on the internal data interfaces of the vehicle, such a PCM can, for example, process video data streams from a camera system or a driver assistance system with sensor data fusion. Such control units sometimes need more than 1500 milliseconds to be fully operational.
Offenbarung der ErfindungDisclosure of the invention
Die Erfindung stellt ein Verfahren zum Ansteuern eines hochauflösenden Scheinwerfers, einen entsprechenden Scheinwerfer, ein entsprechendes Computerprogramm sowie ein entsprechendes Speichermedium gemäß den unabhängigen Ansprüchen bereit.The invention provides a method for controlling a high-resolution headlight, a corresponding headlight, a corresponding computer program and a corresponding storage medium according to the independent claims.
Das erfindungsgemäße Verfahren versetzt ein Fahrzeug mit hochauflösenden Scheinwerfern in die Lage, bestimmte Beleuchtungsfunktionen ohne Wartezeit erfüllen zu können. Dies ermöglicht insbesondere die sofortige Inbetriebnahme der Beleuchtung bei einer Entriegelung des Fahrzeuges per Funkfernbedienung, um dem Fahrer bei Dunkelheit den Weg zum Fahrzeug zu erleichtern („Leaving-Home-Funktion“), sowie die Aktivierung des Abblendlichtes bei eingeschalteter Zündung.The method according to the invention enables a vehicle with high-resolution headlights to perform certain lighting functions without waiting. In particular, this enables the lighting to be switched on immediately when the vehicle is unlocked by radio remote control, in order to make it easier for the driver to get to the vehicle in the dark (“leaving home function”), and to activate the low beam when the ignition is switched on.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Patentansprüchen angegeben.Further advantageous refinements of the invention are specified in the dependent claims.
