Abstract

The door lock has a processor with commands provided on a data bus and which are received for providing an unlocking state. The processing monitoring facility is operated during the driving operation for data traffic on the data bus and operated and transferred at a sustained disruption of traffic from the locked door lock in the unlocked state. A door lock actuator takes appropriate locking or unlocking positions and assigned with an appropriate power supply with a corresponding position activated. The actuator is driven by a motor.

Description

Die Erfindung bezieht sich auf ein Türschloss nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to a door lock the preamble of claim 1.

Derartige Türschlösser sind handelsüblich. Sie werden häufig per Funkfernbedienung gesteuert. Auf einen zentral aufgegebenen und in der Regel codierten Befehl hin werden die in den Türschlössern vorhandenen Auswerteelektroniken durch ein zentrales Steuergerät über die Datenbusverbindung angesprochen. Diese veranlassen die Einstellung eines entsprechenden Zustands der jeweiligen Türschlösser. Als Zustand sind vorzugsweise die Einstellungen in den entriegelten, den verriegelten oder den gesicherten Zustand zu verstehen. Alternativ ist es auch möglich, mittels des zentralen Steuergeräts bei Erreichen einer vorgegebenen Geschwindigkeit von 5 km/h den Auswerteelektroniken selbständig den Befehl zum Einstellen des Zustands „verriegelt" aufzugeben oder diesen Befehl manuell durch einen separaten Schalter zu erzeugen.such Door locks are commercially available. she become common controlled by radio remote control. On a centrally abandoned and usually encoded command out the existing in the door locks Transmitters via a central control unit via the Data bus connection addressed. These cause the attitude a corresponding state of the respective door locks. As condition are preferred the settings in the unlocked, the locked or the one to understand the secure state. Alternatively, it is also possible by means of of the central controller when reaching a predetermined speed of 5 km / h the Transmitters independently abandon the command to set the state "locked" or Manually generate this command through a separate switch.

In diesem Zusammenhang ist es aus der DE4228234 A1 bekannt, bei einem Unfall oder bei einem Fehler des Bordnetzes mit Hilfe eines autarken Energiespeichers ein Stellglied mit Hilfe einer Steuerelektronik zu betreiben, die zusammen mit dem Energiespeicher am Türschloss angeordnet ist. Die Steuerelektronik reagiert dabei selbsttätig auf ein drahtlos aufgegebenes Entriegelungssignal und stellt mittels des Stellglieds dann den Zustand entriegelt ein.In this context, it is from the DE4228234 A1 known to operate in an accident or a fault of the electrical system with the help of a self-sufficient energy storage an actuator by means of control electronics, which is arranged together with the energy storage on the door lock. The control electronics automatically reacts to a wirelessly issued unlocking signal and then sets the state unlocked by means of the actuator.

Voraussetzung für die bekannte Einrichtung sind demnach eine auf einen drahtlos aufgegebenen Befehl hin reagierende Steuerelektronik in jedem Schloss und der drahtlos arbeitende Befehlsgeber. Bei einem Unfall steht dieser meist nicht zur Verfügung. Die in der DE 4228234 A1 angegebene Alternative, den Entriegelungsbefehl durch einen Crashschalter gesteuert zentral zu erzeugen und an die Türschlösser weiterzugeben, setzt die ordnungsgemäße Funktionsfähigkeit einer für die Übertragung dann vorzusehenden Datenbusverbindung voraus.Prerequisite for the known device are therefore a responsive to a wireless command commanded control electronics in each lock and the wireless commander. In an accident this is usually not available. The in the DE 4228234 A1 specified alternative to generate the unlocking command controlled by a crash switch centrally and pass it on to the door locks, requires the proper functioning of a then to be provided for the transmission data bus connection.

Der Erfindung liegt die Aufgabe zugrunde, ein Türschloss der eingangs genannten Art zu schaffen, das mit geringem zusätzlichen Aufwand im Bedarfs- bzw. Notfall die Einstellung des Zustands „entriegelt" sicherstellt.Of the Invention is based on the object, a door lock of the aforementioned To create a species that can be used with little additional effort in the or emergency, the setting of the state "unlocked" ensures.

Die Erfindung löst diese Aufgabe durch die kennzeichnenden Merkmale des Patentanspruchs 1.The Invention solves This object by the characterizing features of the claim 1.

Voraussetzung für die Erfindung ist demnach eine Datenbusverbindung, über die die Auswerteelektroniken der Schlösser ihre Befehle erhalten. Der Datenbus ist ständig aktiv. Er stellt die Kommunikation verschiedener Kraftfahrzeugkomponenten her. Die Auswerteelektronik erkennt, dass der Datenverkehr auf dem Datenbus unterbrochen ist. Dies ist in der Regel durch einen schweren Unfall des Fahrzeugs bedingt. Die Auswerteelektronik veranlasst Iosgelöst vom übrigen Bordnetz die Einstellung des Zustands „entriegelt" an ihrem Schloss.requirement for the Invention is therefore a data bus connection via which the evaluation electronics the locks receive their orders. The data bus is always active. He represents the communication various motor vehicle components ago. The evaluation electronics Detects that the traffic on the data bus is broken. This is usually due to a serious accident of the vehicle conditionally. The transmitter causes Iosgelöst from the rest of the electrical system the setting of the state "unlocked" at her lock.

Gegenüber den aus der DE4228234 A1 bekannten Einrichtungen ist zum Einstellen dieses Zustands kein zusätzlicher Fernbedienungsbefehl erforderlich. Gegenüber der Übertragung des „Entriegelungs"-Befehls über den Datenbus ergibt sich der Vorteil des schnellen und sicheren Einstellens des gewünschten Zustands. Zeitverzögerungen durch Gateways im Signalfluss des Datenbusses werden vermieden.Opposite from the DE4228234 A1 known devices no additional remote control command is required to set this state. Compared with the transmission of the "unlock" command via the data bus, there is the advantage of setting the desired state quickly and reliably, and time delays through gateways in the signal flow of the data bus are avoided.

Es sind auch mehrere entsprechende Schlösser bekannt, die bei einem Ausfall der Strom-/Spannungsversorgung des Bordnetzes selbsttätig in den entriegelten Zustand übergeführt werden. Ein Beispiel hierfür findet sich in der DE 33 13 702 A1 . Demgegenüber ergibt sich durch die Erfindung der Vorteil, ohne Festlegung eines Schwellwertes für die Bordnetzspannung auszukommen und darüber hinaus keine Vorkehrungen gegenüber einer unerwünschten Reaktion bei einer willkürlichen Unterbrechung der Versorgung treffen zu müssen. Ersteres vermeidet ein unerwünschtes Entriegeln bei einer betriebsbedingten extremen Belastung des Bordnetzes und eines durch Serienstreuung bedingten extremen Schwellwert. Letzteres tritt beispielsweise bei einem Einbruchsversuch in das abgestellte Kraftfahrzeug auf.There are also several corresponding locks known to be automatically transferred in case of failure of the power / voltage supply of the electrical system in the unlocked state. An example of this can be found in the DE 33 13 702 A1 , In contrast, results from the invention of the advantage of getting along without establishing a threshold for the vehicle electrical system voltage and beyond to make any arrangements for an undesirable reaction to an arbitrary interruption of supply. The former avoids unwanted unlocking at an operational extreme load on the electrical system and an extreme due to series dispersion extreme threshold. The latter occurs, for example, in a break-in attempt in the parked motor vehicle.

Der Wirkmechanismus ist bei der Erfindung wie folgt: Es liegt eine Nutzung des Fahrzeugs vor. Dieser Zustand unterscheidet sich vom Zustand bei abgestelltem Fahrzeug beispielsweise durch die Aktivierung des Datenbusses, über den die Auswerteelektronik im Bedarfsfall ihre Stellbefehle erhält.Of the Mechanism of action in the invention is as follows: There is a use of the vehicle. This condition differs from the condition when the vehicle is parked, for example, by activating the Data bus, about the evaluation electronics receives their control commands in case of need.

Über den Datenbus werden entsprechend den Zuständen der elektronischen Systeme im Fahrzeug Telegramme übertragen, aus der die Auswerteelektronik erkennen kann, dass das Fahrzeug durch einen autorisierten Benutzer in Betrieb genommen wurde.On the Data bus will be according to the states of the electronic systems transmit telegrams in the vehicle, from which the transmitter can detect that the vehicle was commissioned by an authorized user.

Die Auswerteelektronik ist selbstständig in der Lage durch geeignete Mechanismen zu erkennen, dass die Busverbindung physikalisch gestört ist. Dies kann beispielsweise an Hand des Spannungspegels geschehen. Liegt dieser außerhalb der vorgegebenen Grenzen, liegt der Schluss auf eine physikalische Zerstörung des Datenbusses nahe. Dasselbe gilt dann, wenn der Telgrammverkehr auf dem Datenbus unterbrochen ist. Da sich das Fahrzeug im berechtigten Betrieb befindet, kann dies nur durch einen Unfall oder durch mutwillige Zerstörung geschehen sein.The evaluation electronics are able to recognize by suitable mechanisms that the bus connection is physically disturbed. This can be done, for example, on the basis of the voltage level. If this lies outside the specified limits, the conclusion is close to a physical destruction of the data bus. The same applies if the telegram traffic is interrupted on the data bus. Since the vehicle is in authorized operation, this can only happen through an accident or through deliberate destruction be.

Befindet sich das Schloss im Zustand verriegelt, veranlasst die Überwachungseinrichtung sofort und ohne dass es hierzu eines Schaltbefehls an die Überwachungseinrichtung bedarf, die Einstellung des Zustands entriegelt. Dadurch wird wie vorgeschrieben die Tür im Falle eines Unfalls entriegelt.is Lock locks in the state, causes the monitoring device Immediately and without this being a switching command to the monitoring device needs, the setting of the state unlocked. This will be like prescribed the door unlocked in the event of an accident.

Bei einer vorteilhaften Ausführungsform der Erfindung besitzt das Türschloss ein Stellglied, das dem verriegelten und dem entriegelten Zustand entsprechende Stellungen einnimmt. Dabei kann dem Stellglied ein Energiespeicher zugeordnet sein, der im Bedarfsfall aktiviert ist und das Stellglied in die dem entriegelten Zustand entsprechende Stellung überführt.at an advantageous embodiment The invention has the door lock an actuator that is locked and unlocked appropriate positions occupies. In this case, the actuator a Energy storage to be assigned, which is activated when needed and the actuator in the unlocked state corresponding Position transferred.

Das Stellglied kann mechanisch oder elektromotorisch angetrieben sein. Der Energiespeicher kann vorteilhafterweise im ersten Fall eine bis dahin unter Spannung gehaltene Feder oder im zweiten Fall ein elektrischer Energiespeicher sein. In letzterem Fall kann der Energiespeicher über das Bordnetz aufladbar sein. Damit ergibt sich mit geringem Aufwand eine zuverlässige Möglichkeit, im Bedarfsfall ein Schloss zu entriegeln und eine mechanische Öffnung der jeweiligen Tür zu ermöglichen.The Actuator can be driven mechanically or by electric motor. The energy storage can advantageously in the first case a previously held under tension spring or in the second case be electrical energy storage. In the latter case, the energy storage over the Can be recharged. This results with little effort a reliable one Possibility, if necessary, unlock a lock and a mechanical opening of the respective door to enable.
