Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.advantageous Embodiments of the invention are the subject of the dependent claims.
Erfindungsgemäß wird die Kraftfahrzeugscheibe, insbesondere die Windschutz- und/oder Heckscheibe, dann vor Fahrtbeginn automatisch enteist, wenn die Außentemperatur unter einem vorgebbaren Schwellwert liegt und zusätzlich mindestens ein weiteres Kriterium erfüllt ist. Dazu wird die Kraftfahrzeugscheibe vor Fahrtbeginn automatisch mit einer zur Enteisung geeigneten Flüssigkeit benetzt und zumindest ein Scheibenwischer wird nach Ablauf einer Einwirkzeit automatisch aktiviert. Liegt die Außentemperatur über dem vorgebbaren Schwellwert oder ist kein weiteres Kriterium erfüllt, wird keine automatische Enteisung der Kraftfahrzeugscheibe durchgeführt. Da der Vorgang vollständig automatisch abläuft, wird eine etwaige Vereisung der Kraftfahrzeugscheibe auf eine für den Benutzer besonders komfortable Weise entfernt.According to the invention the vehicle window, in particular the windscreen and / or rear window, then automatically de-iced before starting to drive when the outside temperature is below a predefinable threshold and in addition at least one further criterion is met. This will be the vehicle window before the start of the journey automatically with a De-icing suitable liquid moistened and at least A windshield wiper will automatically after expiry of a contact time activated. If the outside temperature is above the predefinable threshold value or is no further criterion fulfilled, no automatic deicing of the vehicle window is performed. Since the process is completely automatic, is a possible icing of the vehicle window on a for removed the user in a particularly comfortable way.
Ausführungsbeispiele der Erfindung werden im Folgenden anhand einer Zeichnung näher erläutert. Dabei zeigt:embodiments The invention will be described below with reference to a drawing explained. Showing:
In einem ersten Verfahrensschritt S1 wird überprüft, ob die Zündung betätigt wurde. Dazu kann beispielsweise ein entsprechendes Signal eines Fahrassistenzsystems abgerufen werden.In a first method step S1 is checked whether the ignition was actuated. This can for example a corresponding signal of a driver assistance system be retrieved.
Ist dies der Fall, wird in einem zweiten Verfahrensschritt S2 überprüft, ob die Außentemperatur unter einem vorgebbaren Schwellwert liegt und mindestens ein weiteres Kriterium erfüllt ist. Dieses weitere Kriterium ist einer möglichen Ausführungsform zufolge erfüllt, wenn die Außenspiegelbeheizung aktiv ist. In einer alternativen Ausführungsform besteht dieses weitere Kriterium aus einer vorliegenden Vereisung der Kraftfahrzeugscheibe. Hierzu wird die Vereisung von einer fahrzeuginnenseitig angebrachten, auf die Kraftfahrzeugscheibe ausgerichteten Kamera erfasst.is this is the case, is checked in a second method step S2, whether the outside temperature is below a predefinable threshold and at least one other criterion is fulfilled. This further criterion is one possible embodiment fulfilled when the outside mirror heating active is. In an alternative embodiment, this is further criterion from a present icing of the vehicle window. For this purpose, the icing of a vehicle inside attached, captured on the vehicle window camera.
Als Schwellwert für die Außentemperatur wird beispielsweise 0°C vorgegeben. Ergibt die Überprüfung der Außentemperatur eine Unterschreitung des vorgegebenen Schwellwertes, beispielsweise bei einer Außentemperatur von –3°C, und liegt eines der weiteren Kriterien vor, so wird im Verfahrensschritt S2 ein positives Resultat erzielt und mit Verfahrensschritt S3 fortgefahren. Anderenfalls wird die automatische Enteisung der Kraftfahrzeugscheibe im Verfahrensschritt S7 abgebrochen und beendet.When Threshold for the outside temperature, for example 0 ° C specified. Returns the review the outside temperature falls below the specified Threshold, for example at an outside temperature of -3 ° C, and is one of the other criteria before, a positive result is achieved in method step S2 and continued with method step S3. Otherwise, the automatic De-icing of the vehicle window aborted in step S7 and finished.
Die eigentliche physikalische Enteisung der Kraftfahrzeugscheibe erfolgt dann in den folgenden Verfahrensschritten S3 bis S6.The actual physical deicing of the vehicle window takes place then in the following process steps S3 to S6.
Im Verfahrensschritt S3 wird die Kraftfahrzeugscheibe mit einer zur Enteisung geeigneten Flüssigkeit über Scheibenreinigungsdüsen oder separaten Düsen benetzt. Diese Flüssigkeit kann einer Ausführungsform zufolge handelsübliche Enteisungsflüssigkeit umfassen, die sich in einem eigenen Zusatzbehälter befindet. Gemäß einer anderen Ausführungsform wird Wasser aus der Scheibenreinigungsanlage oder aus einem Zusatzbehälter verwendet. Das Wasser kann dabei von einer Komponente des Fahrzeugs, wie z. B. dem Motor oder dem Generator der Standheizung, erwärmt werden. Einer weiteren Ausführungsform zufolge wird von der Antriebseinheit eines Brennstoffzellenfahrzeuges erwärmte Flüssigkeit zur Benetzung der Kraftfahrzeugscheibe verwendet.in the Step S3 is the vehicle window with a for De-icing suitable liquid through window cleaning nozzles or wetted separate nozzles. This liquid According to one embodiment, commercially available De-icing liquid, which is contained in its own additional container located. According to another embodiment is water from the windscreen cleaning system or from an additional container used. The water can be from a component of the vehicle, such as As the engine or the generator of the heater, heated become. According to another embodiment, von heated the drive unit of a fuel cell vehicle Liquid used for wetting the vehicle window.
In einem nächsten Verfahrensschritt S4 wirkt die zur Enteisung geeignete Flüssigkeit eine definierte Zeit, wie z. B. 10 Sekunden, auf die Kraftfahrzeugscheibe ein. Während dieser Einwirkzeit wird im Verfahrensschritt S5 eine Statusmitteilung beispielsweise fahrzeugseitig, z. B. akustisch, ausgegeben und/oder auf einem Display angezeigt.In a next step S4 acts for de-icing suitable liquid for a defined time, such. B. 10 Seconds, on the vehicle window. During this Action time is in step S5 a status message, for example vehicle side, z. B. acoustically, output and / or on a display displayed.
Nach Ablauf der Einwirkzeit wird zumindest ein Scheibenwischer der betreffenden Kraftfahrzeugscheibe im Verfahrensschritt S6 automatisch aktiviert und so das aufgetaute Eis von der Kraftfahrzeugscheibe entfernt.To Expiry of the exposure time is at least one windshield wiper of the relevant Vehicle window automatically activated in step S6 and so the thawed ice away from the vehicle window.
Diese letzten Verfahrensschritte S3 bis S6 können dann, solange die in Verfahrensschritt S2 beschriebenen Kriterien erfüllt sind, automatisch wiederholt werden. Alternativ können diese Verfahrensschritte S3 bis S6 entsprechend einer vorgegebenen Anzahl wiederholt werden. Sind die beschriebenen Kriterien nicht mehr erfüllt, beispielsweise ist die Kraftfahrzeugscheibe enteist, wird deren automatische Enteisung im Verfahrensschritt S7 abgebrochen und beendet.These last method steps S3 to S6 can then, as long as meets the criteria described in step S2 are repeated automatically. Alternatively you can these method steps S3 to S6 corresponding to a predetermined number be repeated. If the criteria described are no longer met, For example, the vehicle window is de-iced, is the automatic de-icing in step S7 aborted and terminated.
Es ist vorgesehen, dass die oben beschriebenen Verfahrensschritte S3 bis S6 zur physikalischen Enteisung der Kraftfahrzeugscheibe auch manuell fahrzeugseitig aktivierbar sind.It it is provided that the above-described method steps S3 to S6 for physical deicing of the vehicle window also manually activated on the vehicle side.
