Bei den bekannten Zentralverriegelungs- oder Komfortsteuerungssystemen kann es sowohl in den Aktuatoren als auch in den Steuereinheiten durch eine große Anzahl von Betätigungen, vorwiegend durch den Benutzer, zu einer schnellen Temperaturerhöhung bis hin zur Überhitzung und damit zum Ausfall der einzelnen Aktuatoren oder Steuereinheiten oder des gesamten Systems kommen.In the known central locking or comfort control systems can it both in the actuators and in the control units by a large number of operations, primarily by the user, to a rapid temperature increase up to overheating and thus failure of the individual actuators or control units or the entire system.

sind in den Unteransprüchen dargestellt.The object is achieved by the features of
Erfindungsgemäß wird die Temperatur jedes der Aktuatoren und/oder des mit den Aktuatoren zusammenarbeitenden Steuergerätes ermittelt. In welchem Bauteil (Aktuator oder Steuergerät) dabei die Temperatur erfaßt wird, hängt von der Temperaturempfindlichkeit der einzelnen Bauteile ab. Bei Überschreiten eines für das entsprechende Bauteil definierten Temperaturschwellenwertes durch die gemessene Temperatur im Bauteil wird ein Steuersignal zur Nichtansteuerung aller Stellelemente der untereinander kommunizierenden Aktuatoren solange erzeugt, bis die erfaßte erhöhte Temperatur in dem Aktuator oder Steuergerät den Temperaturschwellenwert um einen definierten Temperaturwert unterschritten hat. Nach der Erfindung werden also alle zu einer Funktionsgruppe gehörenden Stellelemente, beispielsweise die Aktuatoren der Zentralverriegelungseinrichtung, solange nicht angesteuert, bis die Temperatur des entsprechenden Bauteils den Temperaturschwellenwert um den definierten Temperaturwert unterschreitet. According to the temperature of each of the actuators and / or with the Actuators cooperating control unit determined. In which component (Actuator or control unit) the temperature is recorded depends on the temperature sensitivity of the individual components. If one is exceeded for the corresponding component defined temperature threshold by the measured Temperature in the component becomes a control signal for non-activation of all Control elements of the actuators communicating with each other are generated as long as until the detected elevated temperature in the actuator or control device reaches the temperature threshold has fallen below a defined temperature value. To The invention therefore includes all the control elements belonging to a functional group, for example, the actuators of the central locking device, as long as not controlled until the temperature of the corresponding component reaches the temperature threshold falls below the defined temperature value.
Gemäß einer Weiterbildung der Erfindung wird für jeden Aktuator eine Sicherheitsbetätigung während des Überschreitens des Temperaturschwellenwertes in einem Bauteil zugelassen. Bei einer Zentralverriegelungseinrichtung ist eine Entriegelung der Türen noch möglich.According to a further development of the invention, there is a safety actuation for each actuator permitted in a component when the temperature threshold is exceeded. With a central locking device, the doors can still be unlocked.
Eine weitere Ausbildung der Erfindung sieht vor, daß ein zweiter Temperaturschwellenwert festgelegt wird, dessen Wert kleiner als der Wert des ersten Temperaturschwellenwertes ist. Bei Überschreiten des zweiten Temperaturschwellenwertes in einem Aktuator oder einem Steuergerät wird ein Warnsignal erzeugt und gegebenenfalls zur Anzeige gebracht. Des weiteren kann vorgesehen werden, daß in Abhängigkeit von dem Warnsignal die Ansteuerung der Stellelemente der Aktuatoren modifiziert wird. Hier besteht eine Möglichkeit darin, die Pausenzeiten zwischen den Steuersignalen, mit denen die Stellelemente der Aktuatoren angesteuert werden, zu vergrößern.Another embodiment of the invention provides that a second temperature threshold is set, the value of which is less than the value of the first temperature threshold. If the second temperature threshold is exceeded in an actuator or a Control unit generates a warning signal and, if necessary, displays it. Of it can further be provided that the control depending on the warning signal the control elements of the actuators is modified. Here is one way to the pause times between the control signals with which the actuators of the actuators be controlled to enlarge.
Die Ermittlung der Temperatur erfolgt vorteilhafterweise in den Steuergeräten direkt, beispielsweise durch einen im Steuergerät implementierten Temperatursensor. In den Aktuatoren kann die Temperaturerfassung über eine Ermittlung der Anzahl der Betätigungen pro Zeiteinheit erfolgen.The temperature is advantageously determined directly in the control units, for example by a temperature sensor implemented in the control unit. In the actuators the temperature can be recorded by determining the number of operations per Unit of time.
Der Vorteil der Erfindung liegt dabei insbesondere auch darin, daß bei Überschreitung der Temperatur in einem Bauteil (Aktuator oder Steuergerät) nicht nur der einzelne Aktuator nicht betätigbar ist, sondern das gesamte Funktionssystem synchron für einen bestimmten Zeitraum außer einer zulässigen Sicherheitsbetätigung außer Kraft gesetzt wird. Damit entsteht bei dem Fahrzeugbenutzer nicht das Gefühl, daß ein Fehler des einzelnen Aktuators vorliegt.The advantage of the invention is in particular that if the Temperature in a component (actuator or control unit) not just the individual actuator is not actuatable, but the entire functional system synchronously for a specific one Period beyond a permitted safety operation is overridden. This creates does not give the vehicle user the feeling that a single actuator fault is present.

Das in Figur 1 gezeigte Komfortsteuerungssystem für ein Kraftfahrzeug beinhaltet neben
einer Zentralverriegelungseinrichtung für die Türen VL; VR, HL, HR und die Heckklappe HK
die Steuerung der Fensterheber FL, FR, die Steuerung des rechten und linken Außenspiegels
AL; AR, die Steuerung des Lock-/Unlock-Schalters 7 an der Fahrertür VL, die Innenraumbeleuchtung
LI sowie ein Gesamtdiagnosesystem. Jede der Systemkomponenten weist
einen eigenen Aktuator (in Figur 1 sind nur die Aktuatoren 1 bis 4 der Zentralverriegelungseinrichtung
dargestellt) auf, dessen Stellelement entweder von einem dezentralen Steuergerät
E1 bis E4 oder direkt von dem zentralen Steuergerät ZSG gesteuert wird, wobei der
Lock-/Unlock-Schalter 7 hier ebenfalls über das Steuergerät E1 gesteuert wird. Der Datenaustausch
zwischen den Steuergeräten E1 bis E4 und dem zentralen Steuergerät ZSG
erfolgt beim Ausführungsbeispiel über ein Bussystem D, wobei jedes Steuergerät unter
seiner spezifischen Kennung Informationen an das zentrale Steuergerät sendet. Dieses
wiederum übermittelt seine Daten in den einzelnen Aktuatoren zugeordneten Telegrammen
an die Steuergeräte E1 bis E4.The comfort control system for a motor vehicle shown in FIG. 1 also includes

Im weiteren wird die Erfindung am Beispiel der Steuerung der Zentralverriegelung der einzelnen
Türen dargestellt (Figur 2). Jede der Türen VL, VR, HL, HR ist mit einem als Türschloß
ausgebildeten elektrisch oder pneumatisch angetriebenen Aktuator 1 bis 4 und mit
den zentralen Steuergeräten E1 bis E4 ausgestattet, die miteinander und mit dem zentralen
Steuergerät ZSG über das Bussystem D miteinander kommunizieren. Jeder der Aktuatoren
1 bis 4 weist je nach Einsatzort eine unterschiedliche Anzahl von Signalgebern 5 auf. Die
Signalgeber 5a der Aktuatoren 1 und 2 geben jeweils ein Zustandssignal I1 "System Öffnen"
und die Signalgeber 5b ein Zustandssignal I2 "System Schließen" an die dezentralen Steuereinheiten
E1 und E2. Sie dienen also zur Steuerung der Zentralverriegelungseinrichtung
durch den Benutzer. Die Signalgeber 5c und 5d der Aktuatoren 1 bis 4 senden jeweils ein
Zustandssignal I3, 14, das angibt, ob die jeweilige Tür offen oder geschlossen ist. Die
Signalgeber 5e geben an, ob die Diebstahlsicherung aktiviert ist. Die Türen HL und HR
weisen keine vom Benutzer aktivierbaren Aktuatoren 3 und 4 auf. Aus diesem Grund fehlen
hier die entsprechenden Signalgeber 5a und 5b. Alle Signalgeber sind als Hall-Sensoren
oder Mikroschalter ausgeführt. Jedes der Steuergeräte E1 bis E4 der Aktuatoren 1 bis 4
erhält kontinuierlich die Zustandssignale In seines eigenen Signalgebers 5 als auch die
Zustandsinformationen der anderen Aktuatoren über deren Steuergeräte und berechnet aus
diesen die Steuersignale S1, S2 zur Ansteuerung des ihm zugeordneten Motors M1 bis M4.
Zusätzlich werden alle Zustandssignale In auch dem zentralen Steuergerät ZSG zugeführt,
das weitere nicht dargestellte Funktionen steuert und mit einer Zustandsanzeige 6 verbunden
ist. Die Übertragung der Zustandssignale zwischen den Steuergeräten E1 bis E4 und
dem zentralen Steuergerät ZSG erfolgt im Zeitmultiplexverfahren, wobei das zentrale Steuergerät
den Datenverkehr auf dem Datenbus steuert. Neben den Aktuatoren 1 bis 4 können
die dezentralen Steuergeräte E1 bis E4 auch weitere Aktuatoren steuern. So ist in Figur 2 an
der Tür VL ein Lock/Unlock-Schalter 7 vorgesehen, dessen Steuerung über zusätzliche
elektrische Verbindungen L1 und L2 vom Steuergerät E1 übernommen wird.The invention is further illustrated using the example of controlling the central locking of the individual doors (FIG. 2). Each of the doors VL, VR, HL, HR is equipped with an electrically or pneumatically driven
Aufgrund einer Vielzahl von durch den Fahrzeugbenutzer erfolgender Betätigungen einzelner
Aktuatoren 1 bis 4 in einer kurzen Zeitspanne kann es zu Überhitzungen einzelner
Aktuatoren oder Steuergeräte und im Extremfall zum Ausfall dieser Bauteile kommen. Zur
Vermeidung einer Überhitzung einzelner Aktuatoren 1 bis 4 oder Steuergeräte E1 bis E4
wird die Temperatur ϑ dieser Bauteile erfaßt. In den Steuergeräten kann dies über in ihnen
implementierte nicht dargestellte Temperatursensoren erfolgen. Überschreitet die Temperatur
ϑ des Steuergerätes E1 bis E4 einen unteren Temperaturschwellenwert ϑ2 (Figur 3),
wird von dem Steuergerät ein Warnsignal erzeugt, das über das Bussystem allen anderen
Steuergeräten E1 bis E4 mitgeteilt wird. Aufgrund des Warnsignals werden dann die
Steuersignale S1 und S2, mit denen die Motoren M1 bis M4 der Aktuatoren 1 bis 4
angesteuert werden, modifiziert, so daß sich die Pausenzeit zwischen den Ansteuerungen
der Aktuatoren vergrößert. Überschreitet trotzdem in einem Steuergerät, z. B. E1, die
Temperatur ϑ einen oberen Temperaturschwellenwert ϑ1, wird an alle Steuergeräte ein
Signal gesendet, aufgrund dessen keine Ansteuerung der Aktuatoren 1 bis 4 erfolgt, bis die
Temperatur im Steuergerät E1 den oberen Temperaturschwellenwert ϑ1 um einen definierten
Temperaturwert ϑh unterschritten hat. Es wird jedoch während des Überschreitens des
oberen Temperaturschwellenwertes ϑ1 noch eine einmalige Sicherheitsbetätigung der
Aktuatoren zugelassen, um die Türen gegebenenfalls öffnen zu können.Due to a large number of actuations of
Bei den Aktuatoren besteht die Möglichkeit der Temperaturermittlung über die Erfassung der
Anzahl der Betätigungen B pro Zeiteinheit t. Dazu ist jedem Aktuator 1 bis 4 ein nicht dargestellter
Betätigungszähler zugeordnet, welcher sich im dezentralen Steuergerät E1 bis E4
befindet. Der Betätigungszähler inkrementiert bei jeder Betätigung des Lock/Unlock-Schalters
7, wenn die Pausenzeit Tp zwischen den Betätigungen kleiner als ein vorbestimmter
Wert Ti ist. Liegt die Pausenzeit Tp oberhalb des Wertes Ti dekrementiert der Betätigungszähler,
im Ausführungsbeispiel (Figur 4) um 2. Erreicht der Betätigungszähler die Zahl 50,
erfolgt für eine definierte Zeitspanne Ts keine Ansteuerung der Aktuatoren 1 bis 4. Es wird
jedoch eine einzige Sicherheitsbetätigung Bs "Entriegeln" zugelassen. In dieser Zeit Ts
dekrementiert der Betätigungszähler um 12 und,die Ansteuerung der Aktuatoren 1 bis 4 wird
nach Ablauf der Zeitspanne Ts wieder freigegeben.In the case of the actuators, it is possible to determine the temperature by recording the number of operations B per unit time t. For this purpose, each
