Description
Die Erfindung betrifft ein Kraftfahrzeug mit einem Sensor zum Erkennen der Einfahrt in einem Tunnel und mit einer Belüftungsanlage mit einer Umluftklappe, wobei bei einer Einfahrt in einen Tunnel die Belüftungsklappe geschlossen wird.The invention relates to a motor vehicle with a sensor for detecting the entrance into a tunnel and with a ventilation system with a recirculating air flap, wherein when entering a tunnel, the ventilation flap is closed.
Ein derartiges Kraftfahrzeug ist beispielsweise aus der
Der Erfindung liegt die Aufgabe zugrunde, ein Kraftfahrzeug der eingangs genannten Art zu schaffen, mit dem eine Tunnelerkennung tageszeitunabhängig möglich ist. Die Lösung dieser Aufgabe erfolgt mit einem Kraftfahrzeug mit den Merkmalen des Patentanspruchs 1. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.The invention has for its object to provide a motor vehicle of the type mentioned, with a tunnel detection is independent of time of day possible. The solution of this object is achieved with a motor vehicle having the features of
Bei einem Kraftfahrzeug mit einem Sensor zum Erkennen der Einfahrt in einen Tunnel und mit einer Belüftungsanlage mit einer Umluftklappe, wobei bei einer Einfahrt in den Tunnel die Belüftungsklappe geschlossen wird, ist erfindungswesentlich vorgesehen, dass der Sensor einen nach oben gerichteten Sender aufweist, der elektromagnetische Wellen aussendet und dass der Sensor einen nach oben gerichteten Empfänger zum Empfang der nach oben ausgesendeten und an der Decke des Tunnels reflektierten elektromagnetischen Wellen aufweist. Mit einem solchen Sensor ist eine tageszeitunabhängige Tunnelerkennung möglich. Durch das Aussenden eine elektromagnetischen Welle, die an der Tunneldecke reflektiert und dann wieder empfangen wird, kann die Einfahrt und die Weiterfahrt in einem Tunnel zuverlässig detektiert werden.In a motor vehicle with a sensor for detecting the entry into a tunnel and with a ventilation system with a recirculation flap, which is closed when entering the tunnel, the ventilation flap, it is essential to the invention that the sensor has an upwardly directed transmitter, the electromagnetic waves emits and that the sensor has an upwardly directed receiver for receiving the upwardly emitted and reflected at the ceiling of the tunnel electromagnetic waves. With such a sensor a daytime independent tunnel detection is possible. By emitting an electromagnetic wave, which is reflected on the tunnel ceiling and then received again, the entrance and the onward journey in a tunnel can be reliably detected.
Typische Tunnelhöhen sind zwischen 4 und 8 Metern, so dass auch ein bestimmter zeitlicher Zusammenhang zwischen ausgesendeter und empfangener Welle gegebenenfalls berücksichtigt werden kann. Bevorzugt ist dem Sensor daher eine Auswerteeinheit zugeordnet, die den zeitlichen Zusammenhang zwischen ausgesendeter und empfangener elektromagnetischer Welle prüft. Dies kann einerseits eine Laufzeitmessung sein oder es kann auch derart gestaltet sein, dass der Empfänger nur in einem bestimmten Zeitintervall ab Aussendung eines Signals in Form einer elektromagnetischen Welle aktiviert ist. In einer bevorzugten Ausgestaltung der Erfindung ist die ausgesendete elektromagnetische Welle kodiert. Der Empfänger könnte durch den Empfang der bestimmten kodierten elektromagnetischen Welle zuverlässig feststellen, dass die empfangene Welle tatsächlich auf eine Reflektion zurückgeführt werden kann und es sich nicht um eine zufällig empfange elektromagnetische Welle handelt. Bevorzugt ist die Kombination der Überprüfung über den zeitlichen Zusammenhang und einer kodierten elektromagnetischen Welle.Typical tunnel heights are between 4 and 8 meters, so that a certain temporal relationship between transmitted and received waves can be taken into account if necessary. Preferably, therefore, an evaluation unit is assigned to the sensor, which checks the temporal relationship between emitted and received electromagnetic wave. On the one hand, this may be a transit time measurement or it may also be designed such that the receiver is activated only in a specific time interval from the emission of a signal in the form of an electromagnetic wave. In a preferred embodiment of the invention, the emitted electromagnetic wave is coded. The receiver could reliably determine, by receiving the particular coded electromagnetic wave, that the received wave can indeed be attributed to reflection and is not a randomly received electromagnetic wave. Preferably, the combination of the check on the temporal relationship and a coded electromagnetic wave.
In einer bevorzugten Ausgestaltung der Erfindung wird eine elektromagnetische Welle im sichtbaren Bereich des Lichts und in einer anderen bevorzugten Ausgestaltung der Erfindung im Infrarotbereich ausgesendet und dann auch entsprechend empfangen. Als Sender wird bevorzugt eine Diode verwendet.In a preferred embodiment of the invention, an electromagnetic wave is emitted in the visible range of light and in another preferred embodiment of the invention in the infrared range and then also received accordingly. As a transmitter, a diode is preferably used.
In einer besonders bevorzugten Ausgestaltung der Erfindung weist das Kraftfahrzeug einen Umgebungslichtsensor auf, der zur Steuerung einer Beleuchtungsanlage dient. Bevorzugt dient dieser Umgebungslichtsensor als Empfänger zum Empfang der nach oben ausgerichteten elektromagnetischen Welle. Insofern hätte dieser Sensor eine Zweifachfunktion, so dass damit zur Umsetzung der erfindungsgemäßen Vorrichtung bzw. des erfindungsgemäßen Kraftfahrzeugs nur eine zusätzliche Diode zum Aussenden der elektromagnetischen Welle und eine entsprechenden Auswerteintelligenz für den Empfänger realisiert werden muss.In a particularly preferred embodiment of the invention, the motor vehicle on an ambient light sensor, which serves to control a lighting system. Preferably, this ambient light sensor serves as a receiver for receiving the upwardly directed electromagnetic wave. In this respect, this sensor would have a dual function, so that therefore only one additional diode for emitting the electromagnetic wave and a corresponding Auswerteintelligenz for the receiver must be implemented to implement the device according to the invention or the motor vehicle according to the invention.
In einer anderen bevorzugten Ausgestaltung der Erfindung ist eine Zeitschaltung vorgesehen, die die Umluftklappe erst zeitverzögert nach Einfahrt in den Tunnel schließt. Auf diese Weise wird sichergestellt, dass bei kurzen Tunneln oder Brückendurchfahrten es nicht zu einem unnötigen Schließen der Umluftklappe kommt.In another preferred embodiment of the invention, a timing circuit is provided which closes the recirculation damper only after a time delay after entering the tunnel. In this way, it is ensured that in short tunnels or bridge passages it does not come to an unnecessary closing the recirculation damper.
Bevorzugt sind zur Überprüfung und Absicherung der Tunneldetektion noch weitere Sensoren vorgesehen, mit denen die Tunnelerkennung abgesichert wird. Bevorzugt wird dazu als weiterer Sensor ein nach vorne gerichteter Helligkeitssensor verwendet, mit dem bei hellerer Umgebung die dunklere Tunneleinfahrt erkannt wird. Dieser Sensor dient bevorzugt zur Steuerung der Beleuchtungsanlage und wird daher im Rahmen der vorliegenden Erfindung einer kostengünstigen Doppelnutzung zugeführt. In einer anderen bevorzugten Ausgestaltung der Erfindung wird als weiterer Sensor der nach oben gerichtete Umgebungslichtsensor als zusätzlicher Sensor verwendet, der bei dunklerer Umgebung eine Tunnelbeleuchtung detektiert. Ergänzend können zusätzliche RGB-Dioden vorhanden sein, mit denen eventuell über eine spektrale Analyse spezielle Tunnelbeleuchtungen erkannt werden. In einer anderen bevorzugten Ausgestaltung der Erfindung ist als weiterer Sensor ein Temperatursensor vorhanden, mit dem die Einfahrt in den Tunnel erkannt wird. Dafür kann entweder die konstante Temperatur der Tunneldecke erkannt werden oder es kann zusätzlich der Sprung der Temperatur bei der Einfahrt in den Tunnel detektiert werden. Typischerweise ist es im Tunnel warmer als außerhalb des Tunnels. Ein weiterer Aspekt der Erfindung besteht in der Bereitstellung eines derartigen Sensors für ein Kraftfahrzeug.Preferably, further sensors are provided to check and secure the tunnel detection, with which the tunnel detection is secured. For this purpose, a forward-looking brightness sensor is preferably used as a further sensor, with which the darker tunnel entrance is detected in a brighter environment. This sensor is preferably used to control the lighting system and is therefore supplied in the context of the present invention, a cost double use. In another preferred embodiment of the invention is as a further sensor of the upward directed ambient light sensor used as an additional sensor that detects tunnel illumination in darker surroundings. In addition, additional RGB diodes may be present with which, possibly via a spectral analysis special tunnel lighting can be detected. In another preferred embodiment of the invention as a further sensor, a temperature sensor is provided, with which the entrance is detected in the tunnel. For this purpose, either the constant temperature of the tunnel ceiling can be detected or it can also be detected the jump in temperature at the entrance to the tunnel. Typically, it is warmer in the tunnel than outside the tunnel. Another aspect of the invention is the provision of such a sensor for a motor vehicle.
Nachfolgend wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels weiter erläutert, aus dem sich weitere bevorzugte Ausgestaltungen ergeben.The invention will be further explained with reference to an embodiment shown in the drawing, from which further preferred embodiments result.
