Description
Verfahren und Einrichtung zur automatischen Betätigung der Scheibenwischer (-Motore) bei Fahrzeugen, vornehmlich Kraftfahrzeugen.Method and device for the automatic actuation of the windshield wipers (-Motors) in vehicles, primarily motor vehicles.
Beschreibung Bei wechselhafter Witterung, wie Schauern, Nieselregen, Schneeregen, Spritzwasser oder nach Betätigung der Scheibenwaschanlage ist der Fahrer eines Fahrzeuges, vornehmlich Kraftfahrzeuge 5, recht häufig, und das auch bei schwierigen Verkehrssituationen, gezwungen, eine Hand vom Lenkrad zu nehmen, um die Scheibenwischer (-Motore) eifrund auszuschalten, letzteres, damit die Wischerblätter nicht trockenlaufen. Eine gewisse Verringerung dieser unter Umstanden recht häufigen Beanspruchung des Fahrers wird durch sogenannte Intervallschalter erreicht. Dieses sind Zeitschalter mit einstellbaren Schaltzeiten und dem Scheibenwischermotor vorgeschaltet, so daß er Jetzt nur in wahlweisen Intervallen arbeitet (einmal vor und zurllck wischt). Description In changeable weather such as showers, drizzle, Sleet, spray or after using the windscreen washer is the driver of a vehicle, primarily motor vehicles 5, quite often, even with difficult ones Traffic situations, forced to take one hand off the steering wheel to the wipers (-Motors) to be switched off, the latter so that the wiper blades do not run dry. A certain reduction in this, under certain circumstances, quite frequent use of the Driver is reached by so-called interval switches. These are time switches with adjustable switching times and the windscreen wiper motor connected upstream, so that he now only works at optional intervals (wipes back and forth once).
Gemäß der Erfindung ist der Scheibenwischerschalter Jetzt für den Fahrer sogar völlig tberfldssig, wenn es gewünscht wird. Seine Funktion bleibt parallel erhalten. Sowie die Frontscheibe des Fahrzeuges, vornehmlich Kraftfahrzeuge 5, durch Feuchtigkeit (Regen, Spritzwasser, Nebel oder die betätigte Scheibenwaschanlage) an Klarheit verliert und benetzt ist, schalten sich die Scheibenwischer Uber ihrem Motor und der wiederum über ein Relais oder eine direkte Schaltstufe der Einrichtung automatisch ein, um sich alsdann bei trockengewischter Scheibe auch wieder automatisch abzuschalten.According to the invention, the wiper switch is now for the Drivers even completely superfluous if so desired. Its function remains parallel obtain. As well as the front window of the vehicle, primarily motor vehicles 5, through Moisture (rain, splash water, fog or the activated windscreen washer system) loses clarity and is wetted, the windshield wipers turn on over theirs Motor and that in turn via a relay or a direct switching stage of the device automatically turns on again when the windshield has been wiped dry switch off.
Das Verfahren ist dadurch gekennzeichnet, daß die Brontscheibenfeuchtigkeit elektrisch, vorzugsweise hochfrequent, gemessen wird.The method is characterized in that the Bront disc moisture electrically, preferably at high frequency, is measured.
Der Meßwertaufnehmer der Einrichtung ist vornehmlich auf der Frontscheibeninnenseite befestigt, und zwar an einem von den Scheibenwischerblättern bestrichenen Punkt.The device's transducer is primarily on the inside of the windshield attached, namely at a point streaked by the windshield wiper blades.
Er ist als Kondensator oder Spule ausgebildet. Durch die Feuchtigkeit auf der Außenseite der Frontscheibe entstehen Eapazitäts-, Induktivitäts- oder lämpfungsänderungen oder eine Kombination aus den dreien, die gemessen werden bzw. einen Oszillator (1) verstimmen.oder ein- oder ausschalten, Je nach Schaltungswahl. Für die Messung eignen sich bevorzugt kapazitive oder induktive Schranken mit Relais oder direkt schaltendem Ausgang (3), die den Scheibenwischermotor ein- und ausschalten können.It is designed as a capacitor or coil. Because of the moisture Changes in capacitance, inductance or attenuation occur on the outside of the windshield or a combination of the three that are being measured or an oscillator (1) detune. Or switch on or off, depending on the circuit selected. For the measurement Capacitive or inductive barriers with relays or directly are suitable switching output (3), which can switch the windscreen wiper motor on and off.
Der Oszillator (1) wird in der Rückkopplung oder am frequenzbestimmenden Schwingkreis durch die durch Feuchtigkeit auf der äußeren Frontscheibenseite am Meßwertaufnehmer auf der Innenseite der Frontscheibe erfolgte Kapazitäts-, Induktivitäts- oder Dämpfungszunahme oder eine Kombination aus den dreien beeinflußt. Seine Schwingungen setzen ein oder aus, je nach Schaltungswahl. Durch die anschließenden Demodulator-,(2), Verstärker- und Schaltstufen(3) wird der Scheibenwischermotor geschaltet.The oscillator (1) is in the feedback or on the frequency-determining Oscillating circuit due to moisture on the outer side of the windshield Measured value sensor on the inside of the front window, capacitance, inductance or attenuation increase or a combination of the three. Its vibrations set on or off, depending on the circuit selection. Through the subsequent demodulator -, (2), Amplifier and switching stages (3) switch the windscreen wiper motor.
