Description
Die Erfindung betrifft eine Scheibenwischanlage mit Front- und Heckscheibenwischanlagen bei Kraftfahrzeugen.The invention relates to a windshield wiper system with front and rear window wipers in motor vehicles.
Es ist bekannt, daß heutige Kraftfahrzeuge mit einer selbstschaltenden und sensorgesteuerten Frontscheibenwischanlage ausgestattet sein können, deren Wischvorgänge über sog. optische Regensensoren automatisch gesteuert werden. Diese Steuerungsart besitzt einen durchaus hohen Komfort und eine hohe Bedienerfreundlichkeit für den Benutzer. Allerdings muß dieser Komfort durch einen nicht unerheblichen Kostenblock erkauft werden.It is known that today Motor vehicles with a self-switching and sensor-controlled windscreen wiper system can be equipped whose wiping processes via so-called optical rain sensors can be controlled automatically. This type of control has a very high level of comfort and ease of use for the User. However, this must Comfort can be bought through a not inconsiderable cost block.

Diese sensorlose Steuerung ist zwar im Vergleich zur erstgenannten sensorgesteuerten Steuerung mittels Regensensor eine deutlich preiswertere Lösung mit gleichhohem Komfort, hat jedoch den Nachteil, daß durch das Fehlen eines Regensensors der Beginn des Regenfalles nicht erkannt wird. Die Scheibenwischeranlage muß daher manuell eingeschaltet werden. Danach verhält sich die sensorlose genauso wie die sensorgesteuerte Scheibenwischeranlage: beide Scheibenwischanlagen wischen regenabhängig langsamer oder schneller.This sensorless control is true compared to the first-mentioned sensor-controlled control by means of Rain sensor a significantly cheaper solution with the same level of comfort, has the disadvantage, however, that the lack of a rain sensor did not detect the onset of rain becomes. The windscreen wiper system must therefore be switched on manually become. After that behaves the sensorless as well as the sensor-controlled wiper system: Both windshield wipers wipe more slowly or faster depending on the rain.
Im Prinzip können also beide Arten von Scheibenwischanlagen zur Steuerung der Front- oder Heckscheibenwischer eingesetzt werden. In der Regel setzt man jedoch für den Heckscheibenwischer heute aus Kostengründen fast ausschließlich sehr einfache, lediglich zeitabhängige Steuerungen ein.In principle, both types of windshield wiper systems can can be used to control the front or rear wipers. As a rule, however, you bet for the rear window wiper today almost exclusively for cost reasons simple, only time-dependent Controls.
Es ist daher die Aufgabe der Erfindung, eine Scheibenwischanlage bereitzustellen, bei der ein hoher Steuerungskomfort von Front- und Heckscheibenwischern mit möglichst geringen Kosten erreicht werden kann.It is therefore the object of the invention to provide a windshield wiper system with a high level of control convenience of front and rear wipers can be achieved at the lowest possible cost can.
Diese Aufgabe wird erfindungsgemäß gelöst durch eine Scheibenwischanlage mit voneinander unabhängig gesteuerten Frontund Heckscheibenwischanlagen bei Kraftfahrzeugen mit einer ersten Intervallsteuereinheit für den Frontscheibenwischer, die die Wischvorgänge jeweils in Abhängigkeit des von einem Regensensor fortlaufend erfassten Wasserbedeckungsgrades der Frontscheibe auslöst, mit einer von der ersten unabhängigen, zweiten Intervallsteuereinheit für den Heckscheibenwischer, die aus dem während einer Wischperiode zeitlich mehrmals abgetasteten, messtechnisch erfassten Stromverlaufes des Heckscheibenwischermotors durch Zuordnung zum zeitlichen Verlauf der Wischperiode des Heckscheibenwischers das nachfolgende Wischintervall des Heckscheibenwischers entsprechend zeitlich einstellt, und mit einer Informationsverbindung zwischen der zweiten Intervallsteuereinheit und der ersten Intervallsteuereinheit oder zwischen der zweiten Intervallsteuereinheit und dem Regensensor, wobei der Regensensor den ersten Wischvorgang des Heckscheibenwischers auslöst und die zweite Intervallsteuereinheit die weiteren Wischvorgänge des Heckscheibenwischers unabhängig vom Regensensor auslöst.According to the invention, this object is achieved by a windscreen wiper system with independently controlled front and rear window wiper systems in motor vehicles with a first interval control unit for the windshield wiper, the the wiping processes depending on each the water coverage measured continuously by a rain sensor the windshield triggers with one of the first independent, second interval control unit for the rear wiper that timed out during a wiping period current curve of the Rear window wiper motor by assignment to the time course the wiping period of the rear window wiper, the subsequent wiping interval of the rear window wiper accordingly and with an information link between the second interval control unit and the first interval control unit or between the second Interval control unit and the rain sensor, the rain sensor triggers the first wiping of the rear window wiper and the second interval control unit the further wiping processes of the rear window wiper independently triggered by the rain sensor.
Bei bevorzugten Ausführungsformen dieser erfindungsgemäßen Scheibenwischanlage ist die Informationsverbindung eine elektrische BUS-Leitung des Kraftfahrzeugs. Diese Ausführungsform hat insbesondere bei fuzzygesteuerter Heckscheibenwischanlage den Vorteil, daß auch andere auf der BUS-Leitung ohnehin bereitstehende Informationen (z.B. Fahrgeschwindigkeitssignal, Außentemperatur, usw.) im Steuerungsalgorithmus ausgewertet werden könnten.In preferred embodiments of this windshield wiper system according to the invention, the In Formation connection an electrical bus line of the motor vehicle. This embodiment has the advantage in particular in the case of a fuzzy-controlled rear window wiper system that other information already available on the bus line (eg driving speed signal, outside temperature, etc.) could also be evaluated in the control algorithm.
Weitere Vorteile der Erfindung ergeben sich aus der Beschreibung und der Zeichnung. Further advantages of the invention result itself from the description and the drawing.
