Abstract

In electronic devices which are operated in motor vehicles, it is known to provide a removable control unit as anti-theft protection. However, with these devices anti-theft protection is only ensured if the control unit is actually taken along when the vehicle is left. With the new electronic device, the intention is to monitor suitably the necessity of removing the control unit. For this purpose, the new device is a control device which monitors the operating or parked position of the ignition lock located in the vehicle by means of a control line. The control device activates an electroacoustic playback device and a signal generator for producing an acoustic signal precisely when the ignition lock is in the parked position and the control unit has still not been removed. The electronic devices are likely to be in particular radios and/or cassette players.

Description

Die Erfindung betrifft ein elektronisches Gerät der im Oberbegriff des Anspruchs 1 angegebenen Art.The invention relates to an electronic device in Preamble of claim 1 specified type.

Geräte dieser Art sind bekannt. Insbesondere Autoradios werden, um einem Diebstahl vorzubeugen, zunehmend mit abnehmbaren Bedienteilen ausgestattet. Ein Diebstahlschutz bei solchen Geräten ist jedoch nur gewährleistet, wenn beim Verlassen des Fahrzeuges das Bedienteil auch wirklich abgenommen wird. Die Praxis zeigt, daß dies häufig vergessen wird.Devices of this type are known. Especially car radios are increasingly used to prevent theft removable control panels. A Theft protection for such devices is only guaranteed if that when leaving the vehicle Control panel is really removed. The practice shows that this is often forgotten.

Der Erfindung liegt die Aufgabe zugrunde, ein elektronisches Gerät der im Oberbegriff des Anspruchs 1 angegebenen Art so auszubilden, daß die Notwendigkeit einer Abnahme des Bedienteils geeignet überwacht wird, um dem Benutzer zu gegebenem Zeitpunkt an das Abnehmen des Bedienteils zu erinnern. The invention is based on the object Electronic device in the preamble of claim 1 specified type so that the need a decrease in the control panel is appropriately monitored in order the user at the appropriate time to remove the Control panel to remember.  

Diese Aufgabe wird gemäß der Erfindung durch die im Kennzeichen des Anspruchs 1 angegebenen Maßnahmen gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet.This object is achieved according to the invention by the Characteristic of claim 1 specified measures solved. Advantageous embodiments of the invention are in the Subclaims marked.

Bei dem elektronischen Gerät gemäß der Erfindung wird in vorteilhafter Weise die Stellung des in einem Kraftfahrzeug befindlichen Zündschlosses ausgewertet, um abhängig hiervon zu entscheiden, ob es notwendig ist, das Bedienteil des Gerätes abzunehmen oder nicht. Wird nämlich das Zündschloß eines Kraftfahrzeugs in die "Parkstellung" gebracht, so ist die Wahrscheinlichkeit groß, daß das Fahrzeug auch verlassen wird.In the electronic device according to the invention is in advantageously the position of the in a Motor vehicle located ignition lock evaluated to depending on this, to decide whether it is necessary that Remove the control panel of the device or not. Becomes namely the ignition lock of a motor vehicle in the Bring "parking position" is the probability great that the vehicle is also left.

Für die Auswertung der Zündschloßstellung ist bei dem elektronischen Gerät gemäß der Erfindung eine Steuereinrichtung vorgesehen, die über eine bereits vorhandene oder gegebenenfalls vorzusehende Steuerleitung die Betriebs- oder Parkstellung des Zündschlosses kontrolliert. Die Steuereinrichtung aktiviert eine elektroakustische Wiedergabeeinrichtung sowie einen Signalgenerator, wenn das Zündschloß die Parkstellung einnimmt und das Bedienteil, dessen Abnahme über einen Schaltkontakt gleichfalls von der Steuereinrichtung überwacht wird, noch nicht abgenommen ist.For the evaluation of the ignition lock position is with the electronic device according to the invention a Control device provided that already has a existing or possibly to be provided control line the operating or parking position of the ignition lock controlled. The control device activates one electro-acoustic reproduction device and a Signal generator when the ignition lock is in the park position takes and the control panel, the acceptance of one Switch contact also from the control device is monitored, has not yet been accepted.

Von besonderem Vorteil ist es, als Signalisiereinrichtung die bei elektronischen Geräten bereits für einen anderen Zweck vorhandenen Signalisiereinrichtungen zu benutzen. Dies ist insbesondere bei heute üblichen Autoradios möglich, die neben einem ohnehin vorhandenen NF-Verstärker auch einen Signalgenerator aufweisen, um einen Warnton zu erzeugen, sobald ein bestimmter Sendebereich verlassen oder bei einem Sendersuchlauf kein ausreichend starker Sender gefunden wird.It is particularly advantageous as a signaling device that for electronic devices already for another  Purpose of using existing signaling devices. This is particularly the case with today's car radios possible, in addition to an existing one LF amplifiers also have a signal generator to generate a warning sound when a particular one Leave the broadcast area or none during a channel search sufficiently strong transmitter is found.

Um auf das Abnehmen des Bedienteiles aufmerksam zu machen, kann an Stelle eines Tongenerators in vorteilhafter Weise auch ein Sprachsynthesizer vorgesehen sein, der einen geeigneten Text als Sprachsignal erzeugt. Als elektroakustische Wiedergabeeinrichtung dient auch hier ein NF-Verstärker, der bei Autoradios oder Kombinationen damit ohnehin vorhanden ist sowie im Fahrzeug installierte Lautsprecher, die meist auch schon vorhanden sind.To pay attention to the removal of the control unit can make in place of a tone generator advantageously also a speech synthesizer is provided be that generates a suitable text as a speech signal. Also serves as an electro-acoustic reproduction device here a NF amplifier that is used in car radios or Combinations with it anyway and in Vehicle-installed speakers, which are usually already available.

Für den Fall, daß ein Benutzer das Bedienteil seines Gerätes bewußt nicht regelmäßig abnehmen möchte, oder daß das Fahrzeug in einer abgeschlossenen Garage bzw. beaufsichtigt abgestellt werden soll, ist es von Vorteil, daß die Aktivierung der elektroakustischen Wiedergabeeinrichtung sowie des Signalgenerators durch die Steuereinrichtung über einen Schalter abschaltbar ist. In the event that a user controls his Consciously does not want to lose weight regularly, or that the vehicle in a locked garage or should be parked under supervision, it is advantageous that the activation of the electroacoustic Playback device and the signal generator the control device can be switched off via a switch is.  

Als Steuereinrichtung ist bevorzugt ein Mikroprozessor vorgesehen, über den elektronische Geräte wie Autoradios und/oder Cassettengeräte ohnehin schon verfügen.A microprocessor is preferably used as the control device provided over the electronic devices such as car radios and / or already have cassette devices.
