Abstract
Description
Die vorliegende Erfindung betrifft eine Vorrichtung zur Innenraumbelüftung eines Fahrzeugs mit mindestens einer Sensoreinrichtung zum Detektieren einer Fahrsituation und zur Ausgabe von Sensorsignalen sowie einer Steuereinrichtung zum Schalten in einen Umluftbetrieb auf der Basis der Sensorsignale. Darüber hinaus betrifft die vorliegende Erfindung ein entsprechendes Verfahren zur Innenraumbelüftung eines Fahrzeugs.The The present invention relates to an apparatus for ventilating an interior of a vehicle Vehicle with at least one sensor device for detecting a driving situation and for the output of sensor signals and a Control device for switching to a recirculation mode on the basis the sensor signals. About that In addition, the present invention relates to a corresponding method for interior ventilation of a vehicle.
Der Umluftbetrieb der Innenraumlüftung eines Kraftfahrzeugs dient unter anderem dazu, das Eintreten von Verbrennungsabgasen in die Fahrgastzelle zu verhindern. Es gibt bestimmte Fahrsituationen, in denen es sinnvoll, den Umluftbetrieb zu aktivieren.Of the Recirculation mode of the interior ventilation a motor vehicle is used, inter alia, the occurrence of Prevent combustion exhaust gases in the passenger compartment. There is certain driving situations in which it makes sense to recirculation mode to activate.
Sofern solche Fahrsituationen von einem Algorithmus erkannt werden können, kann der Umluftbetrieb temporär automatisch aktiviert werden. Eine automatische Umluftschaltung in diesen Situationen entlastet den Fahrer und führt zu einer Komfortverbesserung. Beispielsweise wird beim Volkswagen Polo (PQ 24) der Umluftbetrieb der Lüftung beim Einlegen des Rückwärtsgangs automatisch aktiviert, um zu verhindern, dass die vom eigenen Fahrzeug emittierten Abgase in den Fahrgastraum gelangen.Provided Such driving situations can be detected by an algorithm the recirculation mode is temporary be activated automatically. An automatic recirculation circuit in these situations relieves the driver and leads to a comfort improvement. For example, the recirculation mode is used on the Volkswagen Polo (PQ 24) the ventilation when engaging reverse gear automatically activated to prevent being from your own vehicle emitted exhaust gases enter the passenger compartment.

Die Aufgabe der vorliegenden Erfindung besteht darin, das automatische Erkennen von Umluftbetriebsbedingungen zu verbessern bzw. zu vereinfachen.The Object of the present invention is the automatic Recognizing or simplifying recirculation operating conditions.
Erfindungsgemäß wird diese Aufgabe durch eine Vorrichtung nach Anspruch 1 und ein Verfahren nach Anspruch 7 gelöst. Vorteilhafte Weiterbildungen der erfindungsgemäßen Vorrichtung und des erfindungsgemäßen Verfahrens sind in den Unteransprüchen definiert.According to the invention this Task by a device according to claim 1 and a method according to Claim 7 solved. Advantageous developments of the device according to the invention and of the method according to the invention are in the subclaims Are defined.
Die vorliegende Erfindung wird nun anhand der beigefügten Zeichnung näher erläutert, die ein Blockschaltdiagramm eines erfindungsgemäßen Innenraumbelüftungssystems darstellt.The The present invention will now be explained in more detail with reference to the accompanying drawing which a block diagram of an interior ventilation system according to the invention represents.
Das nachfolgend näher geschilderte Ausführungsbeispiel stellt lediglich eine bevorzugte Ausführungsform der vorliegenden Erfindung dar.The below described embodiment merely represents a preferred embodiment of the present invention Invention.
Gemäß
Mit
dieser Innenraumluftsteuerung ist es möglich, in Situationen mit stockendem
Verkehr, z.B. bei einer Schlange vor einer Ampel oder bei Stau, den
Umluftbetrieb automatisch zu aktivieren, um das Ansaugen von Abgasen
von Fremdfahrzeugen zu unterbinden. Optional kann diese Automatik
vom Fahrer überstimmt
und/oder deaktiviert werden. Hierzu ist ein Taster
Zur Erkennung einer entsprechenden Fahrsituation können beliebige nahbereichstaugliche, nach vorne gerichtete Abstands-Sensoren verwendet werden, die im Vorfeld des Fahrzeugs befindliche Hindernisse detektieren. Derartige Abstands-Sensoren können beispielsweise auf der Grundlage von Ultraschall oder Nahbereichsradar realisiert sein.to Recognition of a corresponding driving situation can be made for any near-field suitable Front-facing distance sensors are used in advance detect obstacles located in the vehicle. Such distance sensors can for example, based on ultrasound or near-field radar be realized.
Optional
kann zusätzlich
die Fahrzeuggeschwindigkeit ausgewertet werden, wie dies in
Vorzugsweise
wird die erfindungsgemäße Umluftautomatik
in Fahrzeuge implementiert, die die notwendige Abstandssensorik
bereits für
andere (Assistenz-) Systeme besitzen. Neben dem in Zusammenhang
mit
Die Umluftautomatik kann weiterhin durch die eingangs erwähnten chemischen und physikalischen Sensoren ergänzt werden.The Automatic recirculation can further by the above-mentioned chemical and physical sensors added become.
