Vorteile der ErfindungAdvantages of the invention

Bei dem erfindungsgemäßen Verfahren zum Betreiben eines schlüssellosen Zutrittsystems eine Fahrzeugs wird in einem ersten Schritt über einen Verriegelungsbefehl eine Schließanlage im Sinne eines Verriegelns angesteuert. Zugleich wird ein Dialog mit einem Transponder ausgelöst, anhand dessen erkannt wird, ob sich der Transponder im Innenraum des Fahrzeugs befindet. In einem zweiten Schritt wird die Schließanlage im Sinne eines Entriegelns dann angesteuert, wenn sich der Transponder im Innenraum befindet. Durch das erfindungsgemäße Verfahren wird die Sicherheit gegen unbefugtes Betreten des Kraftfahrzeugs erhöht, indem die Verriegelung in jedem Fall unabhängig von der Positionsbestimmung des Transponders durchgeführt wird. Nur dann, wenn eindeutig das Vorhandensein eines Transponders im Innenraum erkannt wird, wird die Schließanlage in einem zweiten Schritt entriegelt. Bei einer nicht dem Innenraum zuordenbaren Transponderposition verbleibt das Kraftfahrzeug im verschlossenen Zustand. Ein weiterer Vorteil des erfindungsgemäßen Verfahrens besteht darin, daß im Falle eines im Innenraum befindlichen Transponders der entsprechende Entriegelungsvorgang ein akustisches Signal bereitstellt und dem Benutzer mitteilt, daß der Transponder im Fahrzeuginnenraum vergessen wurde. Damit werden zusätzliche akustische oder optische Warneinrichtungen überflüssig.In the inventive method for operating a keyless entry system a vehicle is in one  first step via a locking command Locking system controlled in the sense of locking. At the same time, a dialog with a transponder is triggered, based on which it is recognized whether the transponder is in the Interior of the vehicle is located. In a second step then the locking system in the sense of unlocking controlled when the transponder is in the interior located. By the method according to the invention Security against unauthorized entry into the motor vehicle increased by locking regardless of the position determination of the transponder is carried out. Only if there is a clear presence of one The transponder is recognized in the interior Locking system unlocked in a second step. At a transponder position that cannot be assigned to the interior the motor vehicle remains in the locked state. A there is a further advantage of the method according to the invention in that in the case of one located in the interior The corresponding unlocking process provides an acoustic signal and notifies the user that the transponder in the vehicle interior has been forgotten. So that additional acoustic or optical Warning devices unnecessary.

In einer zweckmäßigen Weiterbildung wird die Schließanlage im Sinne eines Entriegelns zeitverzögert angesteuert.In an expedient development, the locking system Controlled with a time delay in the sense of unlocking.

Dadurch kann eine zeitliche Trennung zwischen dem Auftreten eines Verriegelungsgeräusches und eines Entriegelungsgeräusches realisiert werden, anhand dessen der Benutzer auf den im Innenraum befindlichen Transponder aufmerksam gemacht wird. In einer weitergehenden Ausgestaltung sind den Innenraum erfassende Innenraumantennen vorgesehen, um zu erkennen, ob sich der Transponder im Innenraum des Fahrzeugs befindet. Ein Entriegeln der Schließanlage erfolgt nur dann, wenn zumindest eine der Innenraumantennen ein Antwortsignal des Transponders empfängt. Der Öffnungsvorgang wird somit nur dann eingeleitet, wenn eindeutig erkannt ist, daß sich der Transponder tatsächlich im Innenraum befindet.This can result in a temporal separation between the occurrence a locking sound and one Unlocking noise can be realized, based on which the Users on the transponder located in the interior attention is drawn. In a further Configuration are the interior Indoor antennas are provided to detect whether the Transponder is located in the interior of the vehicle. A The locking system is only unlocked if  at least one of the indoor antennas receives a response signal from the Transponder receives. The opening process is thus only then initiated when it is clearly recognized that the Transponder is actually located inside.

In einer Ausgestaltung sind die Antennen im Türbereich des Fahrzeugs angeordnet.In one embodiment, the antennas are in the door area of the Vehicle arranged.

Weitere zweckmäßige Weiterbildungen ergeben sich aus weiteren abhängigen Ansprüchen und aus der Beschreibung.Further expedient further developments result from further dependent claims and from the description.

Zeichnungdrawing

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert. Es zeigen Fig. 1 ein Flußdiagramm und Fig. 2 eine prinzipielle Antennenanordnung eines Ausführungsbeispiels.An embodiment is shown in the drawing and explained in more detail in the following description. In the drawings Fig. 1 is a flowchart and Fig. 2 shows a basic antenna arrangement of one embodiment.

Beschreibung des AusführungsbeispielsDescription of the embodiment

Fig. 2 läßt sich die Draufsicht auf ein Fahrzeug 10 schematisch entnehmen. Auf jeder Seite sind jeweils zwei Innenraumantennen 12 in Höhe der Vordertür und der Hintertür angeordnet. Zudem sind Außenbereichantennen 14 vorgesehen, deren Abdeckbereiche in Richtung des Außenbereichs hin orientiert sind. Ein Steuergerät 11 steuert eine Schließanlage 13 des Fahrzeugs 10 an. Ein Transponder 16 tauscht mit den Antennen 12, 14 Signale aus. Fig. 2 is a plan view schematically can be found on a vehicle 10. Two interior antennas 12 are arranged on each side at the level of the front door and the rear door. In addition, external area antennas 14 are provided, the covering areas of which are oriented towards the external area. A control unit 11 controls a locking system 13 of the vehicle 10 . A transponder 16 exchanges signals with the antennas 12 , 14 .

Anhand des Flußdiagramms gemäß Fig. 1 wird das erfindungsgemäße Verfahren näher erläutert. Der Benutzer verläßt das Fahrzeug 10 mit dem Wunsch, es zu verriegeln. Hierzu löst er einen Verriegelungsbefehl aus, Schritt 101. Ein entsprechendes Bedienelement wie beispielsweise der Türgriff oder eine Fernbedienung ist in entsprechender Weise zu betätigen.The method according to the invention is explained in more detail with reference to the flow chart according to FIG. 1. The user leaves the vehicle 10 with a desire to lock it. To do this, he triggers a locking command, step 101 . A corresponding control element such as the door handle or a remote control is to be operated in a corresponding manner.

Das zugehörige Steuergerät 11 erkennt den Verriegelungsbefehl und steuert in einem Schritt 103 die Schließanlage 13 oder die Zentralverriegelung mit den zugehörigen Verstellantrieben so an, daß die Türen des Fahrzeugs 10 verriegelt werden. Dies geschieht unabhängig davon, ob sich im Innenraum der Transponder 16 befindet oder nicht. Zugleich veranlaßt das Steuergerät 11 die Antennen 12, 14, ein Fragesignal auszusenden. Befindet sich der Transponder 16 in dem Erfassungsbereich der Antennen 12, 14, wird er dazu angeregt, ein Antwortsignal auszusenden. Die Ansteuerung der Antennen 12, 14 kann entweder zeitgleich oder sequentiell erfolgen. Die Antennen 12, 14 empfangen das vom Transponder 16 ausgesendete Antwortsignal. Für jede der Antennen 12, 14 ist eine Auswerteeinheit vorgesehen, die beispielsweise anhand der erfaßten Feldstärke erkennt, ob die zugeordnete Antenne 12, 14 ein Antwortsignal empfangen hat.The associated control unit 11 recognizes the locking command and controls the locking system 13 or the central locking system with the associated adjustment drives in a step 103 such that the doors of the vehicle 10 are locked. This happens regardless of whether the transponder 16 is in the interior or not. At the same time, the control device 11 causes the antennas 12 , 14 to transmit a question signal. If the transponder 16 is in the detection range of the antennas 12 , 14 , it is stimulated to send out a response signal. The antennas 12 , 14 can be activated either simultaneously or sequentially. The antennas 12 , 14 receive the response signal transmitted by the transponder 16 . An evaluation unit is provided for each of the antennas 12 , 14 , which, for example, recognizes from the detected field strength whether the assigned antenna 12 , 14 has received a response signal.

Es schließt sich eine Abfrage 105 an, ob eine der auf den Innenraum des Fahrzeugs 10 hin orientierten Innenraumantennen 12 ein Antwortsignal des Transponders 16 empfangen hat. Ist dies der Fall, so kann darauf geschlossen werden, daß sich der Transponder 16 im Innenraum befindet. Dann wird die Schließanlage 13 bzw. Zentralverriegelung im Sinne eines Öffnens angesteuert, Schritt 109. Dieses Öffnen wird gegebenenfalls gegenüber dem Verriegelungsvorgang zeitverzögert, beispielsweise um eine Sekunde, durchgeführt. Der Benutzer interpretiert das zweimal auftretende Ver- und Entriegelungsgeräusch in der Weise, daß der Transponder 16 im Innenraum des Fahrzeugs 10 zurückgelassen wurde. Somit kann auf eine zusätzliche optische oder akustische Anzeige verzichtet werden. This is followed by a query 105 as to whether one of the interior antennas 12 oriented toward the interior of the vehicle 10 has received a response signal from the transponder 16 . If this is the case, it can be concluded that the transponder 16 is located in the interior. The locking system 13 or central locking is then activated in the sense of opening, step 109 . This opening is possibly delayed, for example by one second, compared to the locking process. The user interprets the locking and unlocking noise occurring twice in such a way that the transponder 16 has been left in the interior of the vehicle 10 . An additional optical or acoustic display can thus be dispensed with.

Wird anhand der Antennensignale jedoch darauf geschlossen, daß sich kein Transponder 16 im Innenraum befindet, bleibt das Fahrzeug 10 verriegelt, Schritt 107.However, if the antenna signals indicate that there is no transponder 16 in the interior, the vehicle 10 remains locked, step 107 .

In einer alternativen Ausgestaltung ist vorgesehen, daß das Steuergerät 11 lediglich die auf den Innenraum gerichteten Innenraumantennen 12 bei einem Verriegelungsbefehl im Sinne eines Aussendens eines Fragesignals ansteuert. Letztlich ist es nur wesentlich, daß ein Verriegeln dann wieder aufgehoben wird, wenn sich der Transponder 16 im Innenraum befindet. Empfangen die Innenraumantennen 12 daraufhin kein Antwortsignal, ist davon auszugehen, daß sich der Transponder 16 auch tatsächlich nicht im Innenraum befindet.In an alternative embodiment it is provided that the control device 11 only controls the interior antennas 12 directed towards the interior in the event of a locking command in the sense of sending out a query signal. Ultimately, it is only essential that locking is released again when the transponder 16 is in the interior. If the interior antennas 12 then receive no response signal, it can be assumed that the transponder 16 is actually not located in the interior.

Eine weitere mögliche Realisierung sieht für die Ansteuerung und Signalerfassung der Innenraumantennen 12 lediglich ein einziges Steuergerät vor. Hierzu können die Innenraumantennen 12 parallel oder seriell verschaltet sein. Eine weitere Basisstation übernimmt die Ansteuerung und Signalerfassung der Außenraumantennen 14.Another possible implementation provides only a single control device for the control and signal detection of the interior antennas 12 . For this purpose, the interior antennas 12 can be connected in parallel or in series. Another base station controls and signals the exterior antennas 14 .
