Beim erfindungsgemäßen Rundfunkempfänger für ein Fahrzeug, insbesondere Rundfunkempfänger für den Empfang von mit Zusatzsignalen versehenen Rundfunksignalen, mit einer Empfangseinrichtung und einer Steuereinrichtung zur Auswertung der in den Rundfunksignalen enthaltenen Zusatzsignalen sowie zur Ermittlung eines Empfangspegels der von der Empfangseinrichtung empfangenen Rundfunksignale, wird diese Aufgabe dadurch gelöst,

  • daß die Steuereinrichtung während des Empfangs eines Senders durch die Empfangseinrichtung dessen Empfangspegel überwacht und bei einer Verschlechterung des Empfangspegels den Sender kennzeichnende Zusatzsignale und/oder die Empfangsfrequenz des Senders speichert, und
  • daß die Steuereinrichtung die Empfangseinrichtung bei einer Verbesserung des Empfangspegels erneut auf den durch die gespeicherten Zusatzsignale und/oder die gespeicherte Empfangsfrequenz gekennzeichneten Sender abstimmt
    • In the radio receiver according to the invention for a vehicle, in particular a radio receiver for the reception of radio signals provided with additional signals, with a receiving device and a control device for evaluating the additional signals contained in the radio signals and for determining a reception level of the radio signals received by the receiving device, this object is achieved,
  • that the control device monitors the reception level during reception of a transmitter by the reception device and, in the event of a deterioration in the reception level, stores additional signals which characterize the transmitter and / or the reception frequency of the transmitter, and
  • that the control device tunes the receiving device again when the receiving level improves to the transmitter identified by the stored additional signals and / or the stored receiving frequency

    • Die Erfindung geht dabei von der Überlegung aus, daß durch die Abspeicherung der den Sender kennzeichnenden Zusatzinformationen, bzw. der Empfangsfrequenz des Senders, dieser auch nach einer Unterbrechung, wie z. B. durch eine Abschattung der Rundfunksignale verursacht, wieder eingestellt und empfangen werden kann.The invention is based on the consideration that by saving the additional information characterizing the transmitter, or the Reception frequency of the transmitter, this also after an interruption, such as. B. caused by shadowing of the radio signals, reset and can be received.

    Der Vorteil des erfindungsgemäßen Rundfunkempfängers liegt insbesondere darin, daß störende Senderwechsel vermieden werden.The advantage of the radio receiver according to the invention is in particular in that disruptive channel changes are avoided.

    Weitere Vorteile der vorliegenden Erfindung ergeben sich aus den abhängigen Ansprüchen sowie der nachfolgenden Beschreibung eines erfindungsgemäßen Rundfunkempfängers anhand einer Figur, die ein Prinzipschaltbild eines Ausführungsbeispiels des erfindungsgemäßen Rundfunkempfängers zeigt.Further advantages of the present invention result from the dependent ones Claims and the following description of an inventive Broadcast receiver based on a figure, which is a block diagram of a Embodiment of the radio receiver according to the invention shows.

    Zur Erleichterung des Verständnisses der vorliegenden Erfindung sind in der Figur nur die Bestandteile des Rundfunkempfängers dargestellt, die im Zusammenhang mit der Erfindung von Bedeutung sind. To facilitate understanding of the present invention, in the Figure shows only the components of the radio receiver, which in Connection with the invention are important.

    Die Figur zeigt ein Prinzipschaltbild eines Ausführungsbeispiels eines erfindungsgemäßen Rundfunkempfängers mit einer Antenne 1, einer Empfangseinrichtung 2, einem Audioverstärker 3, einem oder mehreren Lautsprechern oder Gruppen von Lautsprechern 4, einer Anzeige 5 sowie einer Steuereinrichtung 6, die beispielsweise von einem Mikrocomputer gebildet werden kann. Außerdem ist ein Anschluß 7 für eine geschaltete Versorgungsspannung vorgesehen, die beispielsweise mittels des Zündschlosses des Fahrzeugs, in den der Rundfunkempfänger eingebaut ist, geschaltet werden kann. In bekannter Weise werden Rundfunksignale von der Antenne 1 empfangen, in der Empfangseinrichtung 2 wird mittels nicht dargestellter Hochfrequenz-, Zwischenfrequenz- und Demodulatorschaltungen ein Rundfunksignal unter Steuerung der Steuereinrichtung 6 ausgewählt. Das Audiosignal des empfangenen Rundfunksignals wird an den Audioverstärker 3 weitergeleitet, der es, gesteuert durch die Steuereinrichtung 6, zur Wiedergabe durch den oder die Lautsprecher 4 verstärkt. Die Empfangseinrichtung 2 stellt der Steuereinrichtung 6 außerdem im Rundfunksignal enthaltene Zusatzinformationen, z. B. nach dem RDS-Standard, zur Verfügung. Die Zusatzinformationen können beispielsweise auf der Anzeige 5 dargestellt werden. Weiterhin kann die Empfangseinrichtung 2 der Steuereinrichtung 6 Informationen über die Empfangsfeldstärke des jeweils empfangenen Senders zur Verfügung stellen.The figure shows a basic circuit diagram of an embodiment of a Radio receiver according to the invention with an antenna 1, one Receiving device 2, an audio amplifier 3, one or more Speakers or groups of speakers 4, a display 5 and one Control device 6, which is formed, for example, by a microcomputer can be. In addition, a connection 7 for a switched Supply voltage provided, for example by means of the ignition lock of the vehicle in which the radio receiver is installed can. Radio signals from the antenna 1 received in the receiving device 2 by means of not shown High frequency, intermediate frequency and demodulator circuits Broadcast signal selected under control of the control device 6. The Audio signal of the received broadcast signal is sent to the audio amplifier 3 passed on, controlled by the control device 6, for playback amplified by the speaker (s) 4. The receiving device 2 provides the Control device 6 also contained in the broadcast signal Additional information, e.g. B. according to the RDS standard. The Additional information can be shown on the display 5, for example. Furthermore, the receiving device 2 of the control device 6 can provide information available via the reception field strength of the respective received transmitter put.

    Wird der, wie oben beschrieben aufgebaute Rundfunkempfänger, der beispielsweise in einem Fahrzeug eingebaut ist, in einem Bereich betrieben, in dem der Rundfunkempfang abgeschattet ist, wie z. B. in einer Unterführung, einem Tunnel oder einer Garage, kommt es zu einer Unterbrechung des Empfangs des eingestellten Senders. Die Unterbrechung wird auch wegen des verringerten Empfangspegels verursacht, durch den der Rundfunkempfänger durch Steuerung der Steuereinrichtung 6 veranlaßt werden kann eine alternative Frequenz des ursprünglich eingestellten Senders einzustellen. Da wegen der Abschattung der Rundfunksignale kein Sender empfangbar ist, bleibt dieser Versuch erfolglos. Auch ein Sendersuchlauf bleibt wegen der Abschattung der Rundfunksignale erfolglos. Deshalb wird störendes Rauschen wiedergegeben. Wird der Abschattungsbereich verlassen, ist der ursprünglich eingestellte Sender verloren. Ein erneuter Suchlauf wird durchgeführt und ein Sender wird zufällig eingestellt und wiedergegeben.If the radio receiver constructed as described above, the for example installed in a vehicle, operated in an area in which the radio reception is shadowed, such. B. in an underpass, a tunnel or a garage, the Receiving the set station. The interruption is also due to the reduced reception level caused by the radio receiver an alternative can be initiated by controlling the control device 6 Frequency of the originally tuned station. Because of the Shadowing of the radio signals no station can be received, this remains Attempt unsuccessful. A station search also remains because of the shadowing of the Broadcast signals unsuccessful. Therefore disturbing noise is reproduced. If you leave the shading area, the originally set transmitter is lost. A new search is carried out and a station becomes random set and played.

    Bei dem erfindungsgemäßen Rundfunkempfänger werden, wenn die Steuereinrichtung 6 eine Verringerung der Empfangsfeldstärke feststellt, von der Steuereinrichtung 6 die über den momentan eingestellten Sender verfügbaren Informationen, wie Senderfrequenz und/oder den Sender kennzeichnende Zusatzinformationen, z. B. PS- und/oder PI-Code, gespeichert. Gleichzeitig steuert die Steuereinrichtung 6 den Audioverstärker 3 an, um die Verstärkung des von der Empfangseinrichtung 2 gelieferten Signals zu beenden, d. h. ein sogenannter NF-Mute wird von der Steuereinheit 6 bewirkt. Dadurch wird kein störendes Rauschen wiedergeben.In the radio receiver according to the invention, if the Control device 6 detects a reduction in the reception field strength from which Control device 6 the available over the currently set transmitter Information such as transmitter frequency and / or the transmitter Additional information, e.g. B. PS and / or PI code, stored. At the same time controls the control device 6 to the audio amplifier 3 in order to amplify the to terminate the signal delivered by the receiving device 2, d. H. on So-called NF mute is effected by the control unit 6. This will not play annoying noise.

    Zur Information für einen Benutzer des Rundfunkempfängers kann auf der Anzeige 5, während der Zeit in der kein Sender wegen der Abschattung der Rundfunksignale empfangen werden kann, ein Hinweis, wie z. B.

    Figure 00040001
    KEIN SENDER" oder NO STATION", unter Steuerung der Steuereinrichtung 6 wiedergegeben werden.For information to a user of the radio receiver, on the display 5, during the time in which no transmitter can be received due to the shadowing of the radio signals, a note such as. B.
    Figure 00040001
    NO TRANSMITTER "or NO STATION ", can be reproduced under the control of the control device 6.

    Nach Beendigung der Abschattung der Rundfunksignale, d. h. wenn von der Steuereinrichtung 6 wieder auswertbare Empfangspegel festgestellt werden, überprüft die Steuereinrichtung 6, ob der vor der Unterbrechung eingestellte Sender noch empfangen werden kann. Dazu wird die gespeicherte Empfangsfrequenz von der Steuereinrichtung 6 an der Empfangseinrichtung 2 eingestellt. Wird kein für den Empfang ausreichender Pegel festgestellt oder weist der jetzt empfangene Sender andere als die abgespeicherten Zusatzinformationen (PI- und/oder PS-Code) auf, wird ein Sendersuchlauf durchgeführt. Die empfangbaren Sender werden auf die abgespeicherten Zusatzinformationen des ursprünglich eingestellten Senders, wie PS- und/oder PI-Code, überprüft. Aufgrund dieser Überprüfung wird der ursprünglich eingestellte und empfangene Sender nach der Unterbrechung erneut eingestellt und wiedergegeben, auch wenn er nunmehr auf einer anderen Frequenz empfangen wird. Wird der ursprünglich eingestellte und empfangene Sender nicht gefunden, wird bevorzugt ein ähnlich gekennzeichneter Sender eingestellt und wiedergegeben. Zur erneuten Wiedergabe steuert die Steuereinrichtung 6 den Audioverstärker 2 an und stellt die ursprünglich eingestellte Lautstärke wieder ein. Gleichzeitig werden auf der Anzeige 5 wieder senderbezogene Informationen dargestellt, wie z. B. Empfangsfrequenz und/oder Sendername.After completion of the shadowing of the broadcast signals, i. H. if from the Control device 6 re-evaluable reception levels are determined, the control device 6 checks whether the one set before the interruption Transmitter can still be received. For this, the saved Reception frequency from the control device 6 at the reception device 2 set. If no level is found or indicates sufficient for reception the station now received is different from the stored one Additional information (PI and / or PS code), a station search carried out. The receivable stations are stored on the Additional information of the originally set station, such as PS and / or PI code, checked. Based on this review, the original tuned and received stations tuned again after the interruption and reproduced, even if it is now on a different frequency Will be received. If the originally set and received station is not found, a similarly marked transmitter is preferably set and reproduced. For renewed playback, the control device 6 controls the Audio amplifier 2 on and restores the originally set volume on. At the same time, transmitter-related information is again shown on the display 5 shown, such as. B. reception frequency and / or station name.

    Abweichend kann es auch vorgesehen sein, daß für den Fall, daß nach Beendigung der Abschattung der ursprünglich eingestellte Sender nicht wieder empfangen werden kann, erst nach einer vorgebbaren Zeitspanne, z. B. 15 Sekunden, nach einem anderen Sender gesucht wird.Deviatingly, it can also be provided that in the event that after The shading of the originally tuned channels does not end again can be received, only after a predetermined period of time, for. B. 15 Seconds after which another station is searched.

    Dies kann insbesondere dann von Vorteil sein, wenn sich das Fahrzeug in einer Garage befand und diese verläßt, weil es im Bereich von z. B. Tiefgaragen oder Parkhäusern zu stark schwankenden Empfangsbedingungen kommen kann. Die Tatsache, daß sich das Fahrzeug in einer Garage befand kann dadurch ermittelt werden, daß die am Anschluß 7 anliegende geschaltete Versorgungsspannung von der Steuereinrichtung 6 überwacht wird. Da in einer Garage beim Abstellen des Fahrzeugs üblicherweise die Zündung des Fahrzeugs ausgeschaltet wird, kann eine Spannungsunterbrechung an Anschluß 7 zur Erkennung eines Aufenthalts des Fahrzeugs in einer Garage von der Steuereinrichtung 6 ausgewertet werden.This can be particularly advantageous if the vehicle is in a Garage was and leaves because it is in the area of z. B. underground garages or Parking garages can experience fluctuating reception conditions. The The fact that the vehicle was in a garage can be determined by this be that the switched supply voltage applied to terminal 7 is monitored by the control device 6. Because in a garage when parking the vehicle's ignition is usually switched off, can a voltage interruption at connection 7 to detect a Stay of the vehicle in a garage by the control device 6 be evaluated.
