Abstract
Description
Die Erfindung betrifft eine Anordnung zum automatischen Abblenden eines Fahrzeugspiegels, insbesondere eines Rückspiegels in einem Fahrzeug, wobei wenigstens eine optische Erfassungseinheit in einem vorgegebenen Umgebungsbereich Lichtsignale erfasst und auswertet.The The invention relates to an arrangement for automatic dimming of a Vehicle mirror, in particular a rearview mirror in one Vehicle, wherein at least one optical detection unit in a Prescribed ambient light signals detected and evaluated.
Aus dem Stand der Technik sind verschiedene Arten von Anordnungen für abblendbare Rückspiegel zur Vermeidung von Blendung eines Fahrzeugführers durch Scheinwerfer eines nachfolgenden Fahrzeuges bekannt. Eine Art der Abblendung erfolgt insbesondere durch eine mechanische Betätigungseinrichtung. Hierbei wird der Rückspiegel vom Fahrzeugführer von Hand entweder in eine Position für Tageslicht oder in eine Position für Nachtfahrten eingestellt.Out In the prior art, various types of arrangements for dimmable rearview mirror to prevent dazzling Driver by headlights of a subsequent Vehicle known. A type of dimming takes place in particular by a mechanical actuator. in this connection The rearview mirror is manually selected by the driver either in a position for daylight or in a position set for night driving.
Darüber hinaus erfolgt ein automatisches Abblenden des Rückspiegels bei einfallendem Licht von hinten über eine Elektronik, welche im Rückspiegel angeordnet ist. Ein Teil dieser Elektronik bilden Sensoren, welche vordere und hintere Lichtverhältnisse erfassen.About that In addition, an automatic dimming of the rearview mirror with incident light from behind via electronics, which is arranged in the rearview mirror. Part of this electronics form sensors, which front and rear lighting conditions to capture.

Der Erfindung liegt die Aufgabe zugrunde, eine Anordnung zum automatischen Abblenden eines Fahrzeugspiegels, insbesondere eines Rückspiegels eines Fahrzeuges, anzugeben, welche ein verbessertes Abblenden des Fahrzeugspiegels ermöglicht.Of the Invention is based on the object, an arrangement for automatic Dimming a vehicle mirror, in particular a rearview mirror a vehicle to indicate which an improved dimming of the Vehicle mirror allows.
Die Aufgabe wird erfindungsgemäß durch die in Anspruch 1 angegebenen Merkmale gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.The The object is achieved by the claim 1 specified characteristics solved. Advantageous developments The invention are the subject of the dependent claims.
Die Erfindung betrifft eine Anordnung zum automatischen Abblenden eines Fahrzeugspiegels, insbesondere eines Rückspiegels in einem Fahrzeug, wobei wenigstens eine optische Erfassungseinheit in einem vorgegebenen Umgebungsbereich Lichtsignale erfasst und auswertet. Erfindungsgemäß ist die optische Erfassungseinheit an der Fahrzeugaußenseite angeordnet, beispielsweise als Rückfahrkamera, ausgeführt. Besonders bevorzugt ist die optische Erfassungseinheit nicht im Fahrzeugspiegel selbst angeordnet, wodurch in vorteilhafter Weise zusätzlicher Bauraum zur Verfügung gestellt ist. Durch die Verwendung der vorhandenen Rückfahrkamera und somit dem Wegfall von im Fahrzeugspiegel integrierten Photodioden ist darüber hinaus eine besonders kostengünstige Vorrichtung gegeben.The The invention relates to an arrangement for automatic dimming of a Vehicle mirror, in particular a rearview mirror in one Vehicle, wherein at least one optical detection unit in a Prescribed ambient light signals detected and evaluated. According to the invention, the optical detection unit arranged on the vehicle outside, for example as a rear view camera, executed. Particularly preferred is the optical detection unit not arranged in the vehicle mirror itself, thereby advantageously additional space is provided. By using the existing rear view camera and thus the elimination of integrated in the vehicle mirror photodiodes is also a particularly cost effective Given device.
Die optische Erfassungseinheit ist dabei derart angeordnet, dass diese insbesondere die zurückliegende Fahrzeugumgebung und somit den rückwärtigen Bereich des eigenen Fahrzeugs aufnimmt. Durch die Verwendung einer Kamera, beispielsweise einer Rückfahrkamera als optische Aufnahmeeinheit, ist insbesondere die vom jeweiligen Erfassungsbereich einfallende Lichtstrahlung, z. B. Blendungen verursachendes Umgebungslicht, wie eine tief stehende Sonne oder Fahrlicht eines das eigene Fahrzeug überholenden Fahrzeugs, direkt und somit ohne störende Einflüsse sicher erfassbar, so dass deren Einfluss auf den Rückspiegel- oder Außenspiegel des eigenen Fahrzeugs bestimmbar ist. Durch ein daraus abgeleitetes Abblendsignal, welches insbesondere mittels der optischen Erfassungseinheit erzeugbar ist, ist sichergestellt, dass von hinten verursachte Blendeinwirkungen durch entsprechendes individuelles Abblenden des Fahrzeugspiegels reduziert und weitgehend vermeidbar sind.The Optical detection unit is arranged such that these in particular the past vehicle environment and thus the rear area of the own vehicle receives. By using a camera, such as a Rear view camera as an optical recording unit, in particular the incident light radiation from the respective detection area, z. B. dazzling ambient light, such as a low-lying Sun or driving light of one's own vehicle overtaking Vehicle, directly and thus without disturbing influences safely detectable, so that their influence on the rearview mirror or exterior mirrors of the own vehicle can be determined. By a derived therefrom dimming signal, which in particular by means of the optical detection unit can be generated is ensured that from behind caused glare by appropriate Individual dimming of the vehicle mirror reduced and largely are avoidable.
Im Zusammenhang mit dieser Erfindung kann es sich bei der optischen Erfassungseinheit um eine oder mehrere Photodioden oder beliebige andere optischen Sensoren handeln. Besonders hat sich ein Einsatz von Bildsensoren bewährt, wobei aus dem Stand der Technik verschiedenartige Bildsensoren, welche sich für einen Einsatz bei Fahrzeugen eignen, bereits bekannt sind. Beispielsweise werden im Zusammenhang mit dieser Erfindung Kameras, welche mit einem CCD-Kamerachip arbeiten eingesetzt.in the In connection with this invention, it may be in the optical Detection unit to one or more photodiodes or any other optical sensors act. In particular, there is a commitment proven by image sensors, being known from the prior art various image sensors, which are suitable for use suitable for vehicles already known. For example, in In connection with this invention, cameras equipped with a CCD camera chip work used.
