Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren zum Regeln einer Fahrzeugleuchte. Ferner betrifft die Erfindung ein Steuergerät für eine Fahrzeugleuchte mit Mitteln zum Regeln der Intensität der Lichtemission der Fahrzeugleuchte.The The present invention relates to a method of controlling a vehicle lamp. Furthermore, the invention relates to a control device for a vehicle lamp with Means for controlling the intensity the light emission of the vehicle lamp.
Die Anzahl der Kraftfahrzeuge im Straßenverkehr nimmt von Jahr zu Jahr zu. Damit steigt das Risiko in einen Verkehrsunfall verwickelt zu werden. Dieses Risiko ist bei Nacht und schlechten Witterungsverhältnissen besonders groß.The Number of motor vehicles in road traffic increases from year to year Year too. This increases the risk involved in a traffic accident to become. This risk is at night and bad weather conditions extraordinary big.
Die Erkennbarkeit der Lichtsignale der Heckleuchten durch nachfahrende Verkehrsteilnehmer, insbesondere unter schwierigen Umweltbedingungen, ist daher für die Sicherheit eines Fahrzeugs besonders wichtig. Die Intensität der Lichtemission der Leuchten, z.B. der Heckleuchten, kann jedoch nicht beliebig erhöht werden, da dies zu einer Blendung anderer Verkehrsteilnehmer führen würde.The Recognizability of the light signals of the rear lights by trailing Road users, especially in difficult environmental conditions, is therefore for the safety of a vehicle is particularly important. The intensity of the light emission the lights, e.g. the tail lights, but can not be arbitrary elevated be, as this would lead to dazzling other road users.
Es ist daher die Aufgabe der vorliegenden Erfindung, ein Verfahren zum Regeln einer Fahrzeugleuchte bereitzustellen, durch welches die Erkennbarkeit der Lichtsignale der Fahrzeugleuchte verbessert wird, jedoch eine Blendung anderer Verkehrsteilnehmer so gering wie möglich gehalten wird. Ferner soll ein Steuergerät der Eingangs genannten Art bereitgestellt werden, mit dem die Fahrzeugleuchte so geregelt werden kann, dass die Erkennbarkeit ihrer Lichtsignale verbessert wird und gleichermaßen eine Blendung anderer Verkehrsteilnehmer vermieden wird.It is therefore the object of the present invention, a method for controlling a vehicle lamp, by which the visibility of the light signals of the vehicle lamp improved but dazzling other road users so low as possible is held. Furthermore, a control device of the type mentioned be provided, with which the vehicle lamp are regulated can improve the visibility of their light signals and alike dazzling other road users is avoided.
Diese Aufgabe wird durch ein Verfahren mit den Merkmalen des Anspruchs 1 und ein Steuergerät mit den Merkmalen des Anspruchs 7 gelöst. Vorteilhafte Aus- und Weiterbildungen ergeben sich aus den Unteransprüchen.These The object is achieved by a method having the features of the claim 1 and a control unit with the features of claim 7 solved. Advantageous training and further education emerge from the dependent claims.
Das erfindungsgemäße Verfahren ist dadurch gekennzeichnet, dass der Abstand nachfolgender Fahrzeuge detektiert wird und dass die Intensität der Lichtemission der Fahrzeugleuchte in Abhängigkeit von dem detektierten Abstand geregelt wird. Die Regelung erfolgt insbesondere so, dass, je näher sich das detektierte nachfolgende Fahrzeug be findet, desto geringer ist die Intensität der Lichtemission der Fahrzeugleuchte. Dabei wird die Intensität der Lichtemission allenfalls bis zu einer vordefinierten Mindestgrenze abgesenkt. Hierdurch kann sichergestellt werden, dass gesetzliche Vorgaben jederzeit eingehalten werden. Falls sich nachfolgende Fahrzeuge weit entfernt von dem Fahrzeug mit der Fahrzeugleuchte befinden, ist somit die Intensität der Lichtemission der Fahrzeugleuchte sehr hoch. Hierdurch wird die Erkennbarkeit der Lichtsignale dieser Fahrzeugleuchte verbessert. Nähert sich das nachfolgende Fahrzeug, würde die hohe Intensität der Lichtemission jedoch zu einer Blendung führen. Ferner ist es für die Erkennbarkeit der Lichtsignale der Fahrzeugleuchte bei einem geringeren Abstand nicht erforderlich, dass die Intensität der Lichtemission den Maximalwert hat. Die Fahrzeugleuchte wird daher so geregelt, dass die Intensität der Lichtemission geringer ist, wodurch eine Blendung des Fahrers des nachfolgenden Fahrzeugs verhindert wird, das Fahrzeug jedoch weiterhin gut erkannt werden kann.The inventive method is characterized in that the distance of subsequent vehicles is detected and that the intensity of the light emission of the vehicle lamp dependent on is controlled by the detected distance. The regulation takes place especially so that, the closer the detected subsequent vehicle be, the lower is the intensity the light emission of the vehicle lamp. Thereby the intensity of the light emission becomes if necessary lowered to a predefined minimum limit. This can ensure that legal requirements be respected at all times. If there are subsequent vehicles far away from the vehicle with the vehicle light, is thus the intensity the light emission of the vehicle lamp very high. This will Improves the visibility of the light signals of this vehicle lamp. approaches The following vehicle, would the high intensity of the light emission however, lead to glare. Furthermore, it is for the recognizability of the light signals of the vehicle lamp at a smaller distance does not require that the intensity of the light emission has the maximum value. The vehicle lamp is therefore regulated so that the intensity the light emission is lower, creating a glare of the driver of the following vehicle is prevented, however, the vehicle continues to be well recognized.
Gemäß einer vorteilhaften Ausbildung des erfindungsgemäßen Verfahrens sind die Lichtquellen der Fahrzeugleuchte Leuchtdioden.According to one advantageous embodiment of the method according to the invention are the light sources of Vehicle light LEDs.
Ferner werden bevorzugt nachfolgende Fahrzeuge mittels einer Parkdistanz-Kontrolleinrichtung detektiert. Mit dieser Parkdistanz-Kontrolleinrichtung können auch Gegenstände oder Verkehrsteilnehmer detektiert werden, die einen bestimmten Abstand zum Fahrzeug unterschreiten. Auf diese Weise kann eine vorhandene Sensorik für die Regelung der Fahrzeugleuchte ausgenutzt werden. Dies führt zu einer Kostenreduzierung und einem geringeren Bauraumbedarf.Further are preferred subsequent vehicles by means of a parking distance control device detected. With this parking distance control device can also objects or road users are detected who have a certain distance fall below the vehicle. In this way, an existing Sensor technology for the regulation of the vehicle lamp be exploited. This leads to a Cost reduction and a smaller space requirement.
Ferner kann bei dem erfindungsgemäßen Verfahren die Intensität der Lichtemission in Abhängigkeit von der Helligkeit erfolgen. Bei Tag oder bei Nacht können somit unterschiedliche Regelungen der Lichtemission der Fahrzeugleuchte vorgenommen werden. Schließlich kann die Regelung von der Fahrzeuggeschwindigkeit abhängen.Further can in the inventive method the intensity the light emission in dependence from the brightness. By day or by night can thus different regulations of the light emission of the vehicle lamp be made. After all the regulation may depend on the vehicle speed.
Gemäß einer bevorzugten Weiterbildung des erfindungsgemäßen Verfahrens überträgt die Parkdistanz-Kontrolleinrichtung einem Fahrzeugbus ein Signal, das dem Abstand des nachfolgenden Fahrzeugs und/oder dem Abstand eines Gegenstands oder Verkehrsteilnehmers entspricht. Ein Steuergerät für die Fahrzeugleuchte liest dieses Signal vom Fahrzeugbus aus und regelt die Intensität der Lichtemission der Fahrzeugleuchte in Abhängigkeit von diesem Signal.According to one preferred development of the method according to the invention transmits the parking distance control device a vehicle bus, a signal which is the distance of the following Vehicle and / or the distance of an object or road user equivalent. A control unit for the vehicle light reads this signal from the vehicle bus and regulates the intensity of the light emission the vehicle lamp depending from this signal.
Das erfindungsgemäße Steuergerät ist gekennzeichnet durch eine Einrichtung zum Detektieren des Abstands nachfolgender Fahrzeuge und durch eine Regeleinrichtung, mit welcher die Intensität der Lichtemission der Fahrzeugleuchte in Abhängigkeit von dem detektierten Abstand regelbar ist. Die Lichtquellen der Fahrzeugleuchte sind insbesondere Leuchtdioden. Die Einrichtung zum Detektieren des Abstands der nachfolgenden Fahrzeuge ist insbesondere eine Parkdistanz-Kontrolleinrichtung oder eine Heckkamera.The Control unit according to the invention is marked by means for detecting the distance following Vehicles and by a control device with which the intensity of the light emission the vehicle lamp depending is controllable by the detected distance. The light sources of Vehicle lights are especially light emitting diodes.
