Description

Schaltvorrichtung für Scheibenwischer von KraftfahrzeugenSwitching device for windscreen wipers of motor vehicles

Die Neuerung betrifft eine Vorrichtung nach dem Oberbegriff des Anspruches 1.The innovation relates to a device according to the preamble of claim 1.

Bei nassem Wetter und Gegenverkehr ist das Autofahren mit Licht in der Regel sehr anstrengend und gefährlich. Insbesondere bei leichtem Nieselregen wird der Scheibenwischer auf Intervallbetrieb geschaltet. Kommt ein Fahrzeug entgegen, verschmutzt die auf der Fahrbahn gebildete Gischt die Windschutzscheibe so stark, daß die Scheibenwischer auf Dauerbetrieb geschaltet werden müssen, um dem Fahrer wieder einigermaßen freie Sicht zu verschaffen. Das Umschalten des Scheibenwischers zwischen diesen beiden Betriebszuständen nimmt zumindest einige Aufmerksamkeit des Fahrzeuglenkers in Anspruch, und zwar gerade zu dem Zeitpunkt, zu dem er sich auf die Verkehrsverhältnisse und insbesondere auf das entgegenkommende Fahrzeug konzentrieren muß.In wet weather and with oncoming traffic, driving with lights on is usually very strenuous and dangerous. In light drizzle in particular, the windshield wipers are switched to intermittent operation. If a vehicle is coming towards you, the spray that forms on the road will dirty the windshield so much that the windshield wipers have to be switched to continuous operation in order to give the driver a somewhat clear view again. Switching the windshield wipers between these two operating modes requires at least some attention from the driver, at the very moment when he needs to concentrate on the traffic conditions and in particular on the oncoming vehicle.

Aufgabe der Neuerung ist es, daß Umschalten der Scheibenwischer von Intervall- auf Dauerbetrieb selbsttätig in Abhängigkeit vom Verkehrsfluß vorzunehmen.The purpose of the innovation is to switch the windscreen wipers automatically from intermittent to continuous operation depending on the traffic flow.

Gemäß der Neuerung wird diese Aufgabe dadurch gelöst, daß in bzw. an der Winschutzscheibe oder an einer anderen, entsprechenden Stelle der Frontfläche des Kraftfahrzeuges ein Sensor vorgesehen ist, der ein entgegenkommendes Fahrzeug feststellt, insbesondere das Licht der Scheinwerfer des entgegenkommenden Fahrzeuges aufnimmt, und den Scheibenwischerantrieb von Intervall- auf Dauer betriebschaltet.According to the innovation, this task is solved by providing a sensor in or on the windshield or at another corresponding location on the front surface of the motor vehicle, which detects an oncoming vehicle, in particular detects the light from the headlights of the oncoming vehicle, and switches the windshield wiper drive from intermittent to continuous operation.

Wenn das Licht des Scheinwerfers eines entgegenkommenden Fahrzeuges auf den Sensor auftrifft, spricht der Sensor an, er erzeugt einen Impuls, der einem Schaltrelais aufgegeben wird, das den Motor des Scheibenwischerantriebs, der im Intervallbetrieb arbeitet, auf Dauerbetrieb umschaltet. Diese Umschaltung erfolgt selbsttätig, d.h., ohne daß der Fahrzeuglenker aktiv werden oder eingreifen muß, so daß der Fahrzeuglenker seine gesamte Aufmerksamkeit auf den Verkehr richten kann.When the headlight light of an oncoming vehicle hits the sensor, the sensor responds and generates a pulse that is sent to a switching relay that switches the windshield wiper motor from intermittent operation to continuous operation. This switchover occurs automatically, i.e. without the driver having to take action or intervene, so that the driver can focus all of his attention on the traffic.

Der Sensor kann wahlweise in die Windschutzscheibe des Fahrzeuges integriert, oder aber auf der dem Fahrzeuginnenraum zugewandten Seite der Windschutzscheibe befestigt, insbesondere festgeklebt sein, so daß der Sensor nicht verschmutzt wird. Der Sensor kann jedoch auch an einer anderen Stelle des Frontteiles des Fahrzeuges, z.B. im Bereich der Scheinwerfer, am Außenspiegel oder dergl. vorgesehen sein, also an einer Stelle, die das Scheinwerferlicht entgegenkommender Fahrzeuge gut aufnehmen kann.The sensor can be integrated into the windshield of the vehicle or attached, in particular glued, to the side of the windshield facing the interior of the vehicle so that the sensor does not become dirty. However, the sensor can also be located at another location on the front of the vehicle, e.g. in the area of the headlights, on the outside mirror or similar, i.e. at a location that can easily absorb the headlights of oncoming vehicles.

Der Sensor ist ein lichtempfindliches Element, z.B. ein Fotoelement bzw. Fotometer, wie z.B. eine Selenzelle, kann jedoch grundsätzlich auch jede andere Art von auf Licht ansprechender Vorrichtung sein, die das aufgenommene Licht in einen elektrischen Impuls umwandelt, der, z.B. nach Verstärkung, ein Schaltrelais beaufschlagt, das einen entsprechenden Impuls zur Umschaltung des Scheibenwischermotors von Intervallbetrieb auf Dauerbetrieb ergibt. Mit einer gewünschten Zeitverzögerung kann der Scheibenwischermotorantrieb wieder auf Dauerbetrieb zurückgeschaltet werden, wobei die Verzögerungsdauer einstellbar ist und der Zeitdauer angepaßt werden kann, die für das Vorbeifahren des entgegenkommenden Fahrzeugs anzusetzen ist.The sensor is a light-sensitive element, e.g. a photoelement or photometer, such as a selenium cell, but can in principle also be any other type of light-responsive device that converts the light received into an electrical pulse that, after amplification, e.g., activates a switching relay that produces a corresponding pulse to switch the windshield wiper motor from intermittent operation to continuous operation. With a desired time delay, the windshield wiper motor drive can be switched back to continuous operation, whereby the delay period is adjustable and can be adapted to the time period that is to be set for the oncoming vehicle to drive past.

Nachstehend wird die Neuerung in Verbindung mit der Zeichnung anhand eines Ausführungsbeispieles erläutert. Es zeigt:The innovation is explained below in conjunction with the drawing using an example of implementation. It shows:

The sensor 4 is connected to a switching relay 8, which converts the electrical pulse generated by the sensor 4 into which the light of the oncoming vehicle 5 detected in the sensor is
