Abstract

With the installation of a light sensor on the car windshield, the light beam from a car travelling in the opposite direction impinging on the sensor causes the main beam to be switched off or dipped, and to revert when the light beam passes. The exact time instant can be determined by the lux light density adjustment on the sensor. The sensor can be used to activate the headlamps in low light conditions e.g. at dusk or in fog. ADVANTAGE- Automatic head-light dipping.

Description

Wie aus Unfallstatistiken bekannt ist, werden häufig Verkehrsunfälle durch Blendung des Fernlichtes hervorgerufen. As is known from accident statistics, traffic accidents are often caused by glare of the high beams. Ursache dieser Blendungen ist, daß der Fahrer vergißt, das Fernlicht wegzuschalten oder reaktional nicht in der Lage ist, den Fernlichthebel rechtzeitig zu betätigen. The cause of this glare that the driver forgets wegzuschalten the high beam or not reaktional able to operate the main beam lever time.

Durch einen handelsüblichen Lichtwertfühler, angebracht z. By a commercially available light value sensor, z attached. B. an der Windschutzscheibe oder am Rückspiegel, also immer einem entgegenkommenden Fahrzeug zugewandt, könnte das automatische Abblenden im eigenen Fahrzeug erreicht werden. B. on the windshield or the rear view mirror, so always facing an oncoming vehicle, the automatic dimming in his own vehicle could be reached.

Bei Annäherung eines entgegenkommenden Fahrzeuges oder auch bei Einfall von Straßenbeleuchtungen wird im eigenen, mit dem Lichtwertfühler ausgestatteten Fahrzeug, durch das Auftreffen des Lichtstrahls auf den Sensor, das Fernlichtrelais abgeschaltet und bei Abschwächung des Lichtstrahles wieder angeschaltet. When approaching an oncoming vehicle or upon incidence of street lighting is in its own, equipped with the light level sensor vehicle turned off by the impingement of the light beam on the sensor, the high beam relay and switched on again in attenuation of the light beam.

Der genaue Zeitpunkt der An- und Abschaltung des Fernlichtrelais kann durch die entsprechende Lux-Einstellung am Lichtwertfühler bestimmt werden. The exact time of activation and deactivation of the high beam relay can be determined by the appropriate Lux setting on the light level sensor. Ebenso kann durch eine entsprechende Einstellung, eine automatische Anschaltung des Abblendlichtes bei abnehmender Tageslichtstärke (z. B. auch bei Nebel) erreicht werden. Likewise, can be accomplished (also in case of fog z. B.) by a corresponding adjustment, an automatic connection of the dipped beam with decreasing daylight level.

Der Lichtwertfühler bezweckt aber auch, daß bei einer gewissen Lichtstärke, z. but the light level sensor also aims that in a certain light intensity, for. B. bei absolutem Tageslicht mit ca. 400 Lux das Fernlicht nicht eingeschaltet werden kann. As in absolute daylight, the beam can not be switched on with 400 lux. Hierbei liegt der Vorteil darin, daß die sogenannte Lichthupe, die bei Überholvorgängen laut Straßenverkehrsordnung einer Nötigung entspricht, automatisch vermieden wird und somit einem Verstoß entgegen wirkt. Here, the advantage is that the so-called flasher corresponding when overtaking, according to road traffic regulations coercion, is automatically avoided and thus counteracts a violation.

  1. Mit dem Einbau eines handelsüblichen Lichtwertfühlers, z. With the installation of a commercial light sensor value, eg. B. an der Windschutzscheibe, wird durch das Auftreffen des Lichtstrahles des entgegenkommenden Fahrzeuges auf den Sensor des Lichtwertfühlers am eigenen Fahrzeug, das Fernlicht automatisch abgeschaltet und bei Rückgang des Lichtstrahles wieder eingeschaltet. B. at the windshield will be automatically switched off by the impingement of the light beam of the oncoming vehicle on the sensor value of the light sensor on the own vehicle, the high beam and switched on again with reduction of the light beam. Der genaue Zeitpunkt kann durch die entsprechende Lux-Einstellung am Lichtwertfühler bestimmt werden. The exact time can be determined by the appropriate Lux setting on the light level sensor. Ebenso kann durch eine entsprechende Einstellung des Lichtwertfühlers eine automatische Anschaltung des Abblendlichtes bei abnehmender Tageslichtstärke (z. B. auch bei Nebel) erreicht werden. Also, an automatic connection of the dipped beam with decreasing daylight level (z. B. even in fog) can be achieved by appropriate adjustment of the light level sensor.
