Definitions
- the invention is based on the method defined in the preamble of claim 1.
- the invention is therefore based on the fact that it is known to clock the power supply of the receiver of a motor vehicle locking system in order to save electricity during parking, that is to say during waiting times, and thus to conserve the energy stored in the motor vehicle's battery.
- Such a system is disclosed in US-A-5 095 308, published March 10, 1992.
- a main problem of such methods is the avoidance of deep discharges of the battery if the vehicle is parked for a long time and the locking system is not operated. During this waiting period, the receiver may receive many different control signals, but none that the locking system has to operate. It may happen that the receiver receives many control signals during this waiting time, but these are intended for other motor vehicles, whereas the control signal intended for this motor vehicle is sometimes only received after a week and even later.
- FIG. 1 therefore shows a person who sends out control signals C coded with the hand transmitter H in order to actuate the locking system installed in the motor vehicle K.
- the handheld transmitter H sends e.g. Infrared light control signals C or radio control signals C off.
- the locking system contains the receiver E also shown in FIG. 2, which receives the control signals C via its antenna (indicated symbolically by D here) and evaluates whether the code of the control signal C indicates that the sending person is authorized to operate the locking system is or not. Depending on the receiver E then emits an actuation signal G which actuates the closures of the motor vehicle K or not.
- the power supply, cf. the battery B of the motor vehicle K is continuously used by the receiver E when the motor vehicle is parked, especially if the waiting times are very long, perhaps weeks.
- a main problem of such power supplies is then the avoidance of deep discharges of the battery B, which not only has to supply the receiver E with power during the waiting times and finally when entering the vehicle, i.e. opening the doors, but especially when the next start Motors has to supply the starter with electricity.
- the invention at least largely avoids deep discharge during the waiting times by clocking the power supply of the receiver E in a special way.
- clocking the power supply B By clocking the power supply B, the energy consumption of the receiver E is considerably reduced.
- FIG. 2 shows the operating switch A, clocked for this purpose during waiting times and alternately switching the power supply B ON and OFF, of the receiver E which can be remotely controlled by a hand transmitter H with the control signals C.
- This operating switch A is in the example shown by a clock generator F using the clock pulse sequence QQQ clocked, the clock pulses Q are separated by more or less long clock pauses P.
- a number of successive waiting times are distinguished in the invention.
- the power consumption of the receiver E may be relatively high, as a result of which the receiver E is then always quickly ready to actuate the locking system immediately when it receives authorized control signals C.
- the operating switch A with a comparatively long cycle pauses P between the ON circuits is activated during a subsequent second waiting time Q of the power supply B operated clocked.
- the clock pauses P are longer during the second waiting time than during the first waiting time.
- they are, for example, 100 msec or 2 seconds each.
- the receiver E is only supplied with current for a short time, namely with the time after increasing pauses P.
- the invention thus largely avoids deep discharges of the battery B by noticeably reducing the power consumption of the receiver from the second waiting time.
- the cycle pauses P in the first waiting time can be made negligible. Then you operate the operating switch A so that it continuously supplies the receiver E with power during the first waiting time, but in the subsequent second waiting time with finely long pauses P between the switch-on phases Q. In this case, the operating switch A is only from the operated second clocked cycle, whereby the receiver E is always immediately ready during the first waiting period to evaluate received control signals C and accordingly immediately to operate the locking system.
- the length of the clock pauses P can be even longer than during the second during further waiting times after the second waiting time Waiting time can be selected. Then the pauses P continue to increase over time and thus the power consumption decreases over time. You can, for example, make the pause duration 5 seconds and even longer.
- the coded control signals C can be repeatedly emitted from the hand transmitter H repeatedly, even if the trigger on the hand transmitter H is actuated only once, over a longer transmission period. It is then expedient to make the duration of the clock pauses P shorter than the duration of the transmission. If the receiver E receives signal fractions during its short ON phase Q, the receiver E is temporarily connected to the battery B via the operating switch A at least for the entire duration of the reception of a complete code, so that the receiver E can now check the authorization of the received code .
- Another development of the invention allows the power-saving, clocked operation to be able to continue undisturbed, even if the receiver E of the parked motor vehicle K has control signals C. receives, which each contain only an unauthorized code, because they are actually only intended for other vehicles, i.e. should operate the locking systems of other vehicles. For this purpose, after receiving such control signals C that do not contain the code that authorizes the actuation of the locking system, the clock frequency QQQ of the actuation of the operating switch A can be made at least approximately the same size as it would have been without the reception of this control signal C. It is then avoided that the receipt of an unauthorized code immediately triggers the beginning of the first waiting time and thus again a period with high power consumption.
- the clock frequency QQQ of the actuation of the operating switch A can again be used during the subsequent first waiting time correspond to the usual power supply.
- the first waiting time can only be started again when the motor vehicle battery is recharged.
- the clock frequency QQQ of the actuation of the operating switch A can only correspond to the clock frequency QQQ of such actuations occurring during the first waiting time if the motor of the Vehicle was started.
- a deep discharge of battery B can be avoided with even greater reliability by not letting the first waiting period begin again until the battery of the motor vehicle has been sufficiently recharged.
- the voltage can at least occasionally of the battery B can be measured, the pause time P being determined as a function of the measured voltage of the battery B.
- the clock frequency QQQ of the actuation of the operating switch A is not always the same during the first waiting time, that is to say immediately when parking begins. Instead, this clock frequency also depends on the current state of charge of the battery B, for example by using a power supply mode immediately after parking that corresponds to the second or a later waiting time - the clock frequency QQQ then possibly being reduced even further in later waiting times can be.
- the locking system installed in the motor vehicle K - e.g. also directly in the housing of the receiver E - contain a clock F, which should operate the operating switch A clocked during the relevant waiting times.
- the clock F e.g. can contain or represent a flip-flop.
- the clock can, e.g. also an electronic counter, a clock or the like. be.
- the subsequent reduction in the clock frequency Q-Q-Q that is the later extension of the pauses P, can also be achieved in that the clock generator F contains an electronic frequency reducer.
- the clock generator F can contain a storage capacitor which, at least until the next actuation of the operating switch A, requires operating energy to operate the clock generator F saves. So you can have your own permanent direct power supply I of the clock F avoid, cf. the direct power supply I of the clock generator F indicated by dashed lines in FIG. 2. Instead, the power supply of the clock generator F can then also take place via the operating switch A.

Die Erfindung und Weiterbildungen derselben werden anhand der in den Figuren gezeigten Schemen von Ausführungsbeispielen der Erfindung weiter erläutert, welche der Übersichtlichkeit wegen jeweils möglichst einfach dargestellt wurden. Dabei zeigt die Figur
- 1
- eine Person, welche mit dem Handsender Steuersignale aussendet, um das im Kfz angebrachte Schließsystem zu betätigen, und
- 2
- ein vereinfachtes Prinzipschema für den Aufbau einer im Kfz angebrachten Anordnung zur Durchführung des erfindungsgemäßen Verfahrens.
- 1
- a person who sends control signals with the hand transmitter to operate the locking system installed in the motor vehicle, and
- 2nd
- a simplified schematic diagram for the construction of an arrangement mounted in the motor vehicle to carry out the method according to the invention.
Die Figur 1 zeigt also eine Person, welche mit dem Handsender H codierte Steuersignale C aussendet, um das im Kfz K angebrachte Schließsystem zu betätigen. Der Handsender H sendet also z.B. Infrarotlicht-Steuersignale C oder Funk-Steuersignale C aus.FIG. 1 therefore shows a person who sends out control signals C coded with the hand transmitter H in order to actuate the locking system installed in the motor vehicle K. The handheld transmitter H sends e.g. Infrared light control signals C or radio control signals C off.
Das Schließsystem enthält den auch in der Figur 2 gezeigten Empfänger E, der über seine - hier symbolisch durch D angedeutete - Antenne die Steuersignale C empfängt und dahin gehend auswertet, ob der Code des Steuersignales C anzeigt, daß die sendende Person zur Betätigung des Schließsystemes berechtigt ist oder nicht. Je nachdem gibt der Empfänger E anschließend ein die Verschlüsse des Kfz K betätigendes Betätigungssignal G ab oder nicht.The locking system contains the receiver E also shown in FIG. 2, which receives the control signals C via its antenna (indicated symbolically by D here) and evaluates whether the code of the control signal C indicates that the sending person is authorized to operate the locking system is or not. Depending on the receiver E then emits an actuation signal G which actuates the closures of the motor vehicle K or not.
Die Stromversorgung, vgl. die Batterie B des Kfz K, wird beim Parken des Kfz durch den Empfänger E laufend beansprucht, besonders wenn die Wartezeiten sehr lange, vielleicht Wochen lange andauern. Ein Hauptproblem solcher Stromversorgungen ist dann aber die Vermeidung von Tiefentladungen der Batterie B, die ja nicht nur den Empfänger E während der Wartezeiten sowie schließlich beim Betreten des Kfz, also Öffnen der Türen mit Strom zu versorgen hat, sondern vor allem auch beim nächsten Starten des Motors den Anlasser mit Strom zu versorgen hat.The power supply, cf. the battery B of the motor vehicle K is continuously used by the receiver E when the motor vehicle is parked, especially if the waiting times are very long, perhaps weeks. A main problem of such power supplies is then the avoidance of deep discharges of the battery B, which not only has to supply the receiver E with power during the waiting times and finally when entering the vehicle, i.e. opening the doors, but especially when the next start Motors has to supply the starter with electricity.
Es soll also vor allem eine Tiefentladung der Batterie B vermieden werden, falls das Kfz K lange Zeit geparkt steht und das Schließsystem nicht betätigt wird. Möglicherweise empfängt aber überdies der Empfänger E in diesen Wartezeiten viele verschiedene Steuersignale C, aber keines, welches das Schließsystem zu betätigen hat. Es kann nämlich vorkommen, daß der Empfänger E in diesen Wartezeiten viele Steuersignale C empfängt, welche nur für andere Kfz bestimmt sind, wohingegen das Steuersignal C, welches für das hier betrachtete Kfz K bestimmt ist, manchmal erst nach einer Woche oder noch später empfangen wird. Der Empfänger E verbraucht also in den Wartezeiten auch mehr oder weniger viel Strom um zu prüfen, ob inzwischen empfangene Steuersignale C von der berechtigten Person bzw. vom berechtigten Handsender H, oder von Unberechtigten kommen.In particular, deep discharge of battery B is to be avoided if motor vehicle K is parked for a long time and the locking system is not actuated. But may receive moreover, the receiver E has many different control signals C during these waiting times, but none which has to operate the locking system. It can happen that the receiver E receives many control signals C during these waiting times, which are only intended for other motor vehicles, whereas the control signal C, which is intended for the motor vehicle K under consideration here, is sometimes only received after a week or even later . The receiver E also consumes more or less electricity in the waiting times to check whether control signals C received in the meantime come from the authorized person or from the authorized handheld transmitter H, or from unauthorized persons.
Die Erfindung vermeidet eine Tiefentladung während der Wartezeiten zumindest weitgehend, indem die Stromversorgung des Empfängers E in spezieller Weise getaktet wird. Durch das Takten der Stromversorgung B wird der Energieverbrauch des Empfängers E erheblich reduziert.The invention at least largely avoids deep discharge during the waiting times by clocking the power supply of the receiver E in a special way. By clocking the power supply B, the energy consumption of the receiver E is considerably reduced.
Die Figur 2 zeigt den zu diesem Zweck während Wartezeiten getakteten, die Stromversorgung B abwechselnd EIN- und AUSschaltenden Betriebsschalter A des durch einen Handsender H mit den Steuersignalen C fernsteuerbaren Empfängers E. Dieser Betriebsschalter A wird im gezeigten Beispiel durch einen Taktgeber F mittels der Taktimpulsfolge Q-Q-Q getaktet, wobei die Taktimpulse Q durch mehr oder weniger lange Taktpausen P getrennt sind.FIG. 2 shows the operating switch A, clocked for this purpose during waiting times and alternately switching the power supply B ON and OFF, of the receiver E which can be remotely controlled by a hand transmitter H with the control signals C. This operating switch A is in the example shown by a clock generator F using the clock pulse sequence QQQ clocked, the clock pulses Q are separated by more or less long clock pauses P.
Bei der Erfindung werden mehrere aufeinander folgende Wartezeiten unterschieden. In der ersten Wartezeit, welche z.B. nur Stunden oder ein bis zwei Tage andauert, darf der Stromverbrauch des Empfängers E relativ hoch sein, wodurch der Empfänger E dann ständig schnell bereit ist, sofort das Schließsystem zu betätigen, wenn er berechtigte Steuersignale C empfängt. Falls aber der Empfänger E keine berechtigten Steuersignale C während dieser ersten Wartezeit empfing, wird während einer folgenden zweiten Wartezeit der Betriebsschalter A mit vergleichsweise lange andauernden Taktpausen P zwischen den EIN-schaltungen Q der Stromversorgung B getaktet betrieben. Die Taktpausen P sind während der zweiten Wartezeit länger als während der ersten Wartezeit. Sie betragen während der zweiten Wartezeit z.B. jeweils 100 msec oder 2 sec. Dadurch wird der Empfänger E jeweils nur kurzzeitig mit Strom versorgt, und zwar mit der Zeit jeweils nach größer gewordenen Taktpausen P.A number of successive waiting times are distinguished in the invention. In the first waiting period, which lasts, for example, only hours or one or two days, the power consumption of the receiver E may be relatively high, as a result of which the receiver E is then always quickly ready to actuate the locking system immediately when it receives authorized control signals C. If, however, the receiver E did not receive any authorized control signals C during this first waiting time, the operating switch A with a comparatively long cycle pauses P between the ON circuits is activated during a subsequent second waiting time Q of the power supply B operated clocked. The clock pauses P are longer during the second waiting time than during the first waiting time. During the second waiting time, they are, for example, 100 msec or 2 seconds each. As a result, the receiver E is only supplied with current for a short time, namely with the time after increasing pauses P.
Die Erfindung vermeidet also Tiefentladungen der Batterie B weitgehend dadurch, daß der Stromverbrauch des Empfängers ab der zweiten Wartezeit spürbar reduziert wird.The invention thus largely avoids deep discharges of the battery B by noticeably reducing the power consumption of the receiver from the second waiting time.
Um in der ersten Wartezeit, welche z.B. nur einige Stunden oder einen Tag lang oder wenige Tage lange dauert, Verzögerungen der Betätigungen des Schließsystemes vermeiden zu können, kann man die Taktpausen P in der ersten Wartezeit verschwindend klein machen. Dann betreibt man also den Betriebsschalter A so, daß er während der ersten Wartezeit den Empfänger E ständig mit Strom versorgt, aber in der anschließenden zweiten Wartezeit mit endlich langen Taktpausen P zwischen den EINschaltphasen Q. In diesem Falle wird also der Betriebsschalter A erst ab der zweiten Wartezeit getaktet betrieben, wodurch der Empfänger E während der ersten Wartezeit stets sofort bereit ist, empfangene Steuersignale C auszuwerten und dementsprechend sofort das Schließsystem zu betätigen.In the first waiting period, which e.g. takes only a few hours or a day or a few days to be able to avoid delays in the actuation of the locking system, the cycle pauses P in the first waiting time can be made negligible. Then you operate the operating switch A so that it continuously supplies the receiver E with power during the first waiting time, but in the subsequent second waiting time with finely long pauses P between the switch-on phases Q. In this case, the operating switch A is only from the operated second clocked cycle, whereby the receiver E is always immediately ready during the first waiting period to evaluate received control signals C and accordingly immediately to operate the locking system.
Um aber auch schon während der ersten Wartezeit deutlich Strom zu sparen, um also während aller Wartezeiten besonders viel der in der Batterie B gespeicherte Energie sparen zu können, kann man auch schon in der ersten Wartezeit die Taktpausen P endlich groß machen, so daß der Betriebsschalter A in der ersten Wartezeit mit höherer Taktfrequenz, vgl. Q-Q-Q, betrieben wird als während der zweiten Wartezeit. Ab der zweiten Wartezeit wird dann besonders stark gespart.However, in order to save considerable electricity even during the first waiting time, in order to be able to save a lot of the energy stored in the battery B during all waiting times, one can finally make the clock pauses P large in the first waiting time, so that the operating switch A in the first waiting time with a higher clock frequency, cf. Q-Q-Q, is operated as during the second waiting period. From the second waiting time, savings are particularly strong.
Um besonders lange Wartezeiten sparsam überbrücken zu können, kann während weiterer Wartezeiten nach der zweiten Wartezeit die Länge der Taktpausen P noch größer als während der zweiten Wartezeit gewählt werden. Dann nehmen also die Pausendauern P mit der Zeit weiter zu und damit der Stromverbrauch mit der Zeit weiter ab. Man kann z.B. die Pausendauern auch 5 sec und noch länger machen. Man kann also für so späte Wartezeiten gewisse Beeinträchtigungen des Kfz-Benutzers in Kauf nehmen, um Tiefentladungen möglichst zu vermeiden, wobei aber durch den erfindungsgemäßen Betrieb anfänglich, in der ersten Wartezeit, praktisch keine Beeinträchtigung des Kfz-Benutzers erfolgt.In order to be able to bridge particularly long waiting times economically, the length of the clock pauses P can be even longer than during the second during further waiting times after the second waiting time Waiting time can be selected. Then the pauses P continue to increase over time and thus the power consumption decreases over time. You can, for example, make the pause duration 5 seconds and even longer. One can therefore accept certain impairments of the motor vehicle user for such late waiting times in order to avoid deep discharges as far as possible, but with the operation according to the invention initially practically no impairment of the motor vehicle user occurs in the first waiting time.
Manche Kfz-Benutzer mögen jedenfalls anfänglich etwas irritiert sein, wenn manchmal das Schließsystem sofort ansprach, wenn der Handsender H betätigt wurde, aber manchmal deutlich verzögert. Dieser Benutzer versteht nämlich anfänglich vielleicht noch nicht, daß dies mit der Gesamtdauer der Wartezeiten zusammenhängt. Um den Benutzer des Kfz möglichst wenig zu irritieren, sein Schließsystem könne defekt geworden sein, kann die Länge der Taktpausen P mehr oder weniger gleichmäßig mit der Zeit zunehmen, statt die Pausen P deutlich in Stufen zu vergrößern.In any case, some motor vehicle users may be a bit irritated at first, when sometimes the locking system responded immediately when the handheld transmitter H was pressed, but sometimes with a significant delay. This user may not initially understand that this is related to the total length of the waiting time. In order to irritate the user of the motor vehicle as little as possible that his locking system may have become defective, the length of the cycle breaks P can increase more or less uniformly over time, instead of increasing the breaks P significantly in stages.
Um trotz längerer Pausendauern P den Handsender H nur wenige Mal, z.B. nur ein einziges Mal, bedienen zu müssen, um das Schließsystem zu betätigen, können die codierten Steuersignalen C - auch bei nur einmaligem Betätigen eines Auslösers des Handsenders H - während einer längeren Sendedauer hintereinander vielfach wiederholt vom Handsender H abgestrahlt werden. Es ist dann günstig, die Dauern der Taktpausen P kürzer zu machen als die Sendedauer andauert. Falls der Empfänger E während seiner kurzen EINschaltphase Q Signalbruchteile empfängt, wird der Empfänger E vorübergehend zumindest während der ganzen Dauer des Empfanges eines vollständigen Code über den Betriebsschalter A mit der Batterie B verbunden, so daß nun der Empfänger E die Berechtigung des empfangenen Code prüfen kann.In order to use the hand-held transmitter H only a few times, e.g. only once, in order to operate the locking system, the coded control signals C can be repeatedly emitted from the hand transmitter H repeatedly, even if the trigger on the hand transmitter H is actuated only once, over a longer transmission period. It is then expedient to make the duration of the clock pauses P shorter than the duration of the transmission. If the receiver E receives signal fractions during its short ON phase Q, the receiver E is temporarily connected to the battery B via the operating switch A at least for the entire duration of the reception of a complete code, so that the receiver E can now check the authorization of the received code .
Eine andere Weiterbildung der Erfindung gestattet, den stromsparenden getakteten Betrieb ungestört fortsetzen zu können, auch wenn der Empfänger E des parkenden Kfz K Steuersignale C empfängt, welche jeweils nur einen unberechtigten Code enthalten, weil sie eigentlich nur für andere Kfz bestimmt sind, also die Schließsysteme anderer Kfz betätigen sollen. Dazu kann nämlich nach dem Empfang von solchen Steuersignalen C, die nicht jenen Code enthalten, der zum Betätigen des Schließsystemes berechtigt, die Taktfrequenz Q-Q-Q der Betätigung des Betriebsschalters A zumindest angenähert wieder gleich groß gemacht werden wie sie ohne den Empfang dieses Steuersignales C gewesen wäre. Man vermeidet dann also, daß der Empfang eines unberechtigten Code unmittelbar den Beginn wieder der ersten Wartezeit und damit erneut eine Periode mit hohem Stromverbrauch auslöst.Another development of the invention allows the power-saving, clocked operation to be able to continue undisturbed, even if the receiver E of the parked motor vehicle K has control signals C. receives, which each contain only an unauthorized code, because they are actually only intended for other vehicles, i.e. should operate the locking systems of other vehicles. For this purpose, after receiving such control signals C that do not contain the code that authorizes the actuation of the locking system, the clock frequency QQQ of the actuation of the operating switch A can be made at least approximately the same size as it would have been without the reception of this control signal C. It is then avoided that the receipt of an unauthorized code immediately triggers the beginning of the first waiting time and thus again a period with high power consumption.
Um die erste Wartezeit nach einer erneuten Benutzung des Kfz wieder rechtzeitig beginnen lassen zu können, kann nach dem Empfang von solchen Steuersignalen C, welche jenen Code enthalten, der zum Betätigen des Schließsystemes berechtigt, die Taktfrequenz Q-Q-Q der Betätigung des Betriebsschalters A wieder der während der anschließenden ersten Wartezeit üblichen Stromversorgungsweise entsprechen.In order to be able to start the first waiting time in good time again after using the motor vehicle again, after receiving such control signals C which contain the code which authorizes the actuation of the locking system, the clock frequency QQQ of the actuation of the operating switch A can again be used during the subsequent first waiting time correspond to the usual power supply.
Um mit erhöhter Sicherheit eine Tiefentladung der Batterie B zu vermeiden, kann man nach einer erneuten Benutzung des Kfz K die erste Wartezeit erst dann wieder beginnen lassen, wenn die Batterie des Kfz nachgeladen wird. Dazu kann nach dem Empfang von solchen Steuersignalen C, welche jenen Code enthalten, der zum Betätigen des Schließsystemes berechtigt, die Taktfrequenz Q-Q-Q der Betätigung des Betriebsschalters A erst dann wieder der während der ersten Wartezeit auftretenden Taktfrequenz Q-Q-Q solcher Betätigungen entspricht, wenn zuvor der Motor des Kfz angelassen wurde.In order to avoid a deep discharge of the battery B with increased certainty, after using the motor vehicle K again, the first waiting time can only be started again when the motor vehicle battery is recharged. For this purpose, after receiving such control signals C, which contain the code that authorizes the actuation of the locking system, the clock frequency QQQ of the actuation of the operating switch A can only correspond to the clock frequency QQQ of such actuations occurring during the first waiting time if the motor of the Vehicle was started.
Mit noch größerer Zuverlässigkeit kann man eine Tiefentladung der Batterie B vermeiden, indem man die erste Wartezeit erst dann wieder beginnen läßt, wenn die Batterie des Kfz ausreichend nachgeladen wurde. Dazu kann während Wartezeiten, z.B. ab der zweiten Wartezeit, zumindest von Zeit zu Zeit die Spannung der Batterie B gemessen werden, wobei die Pausendauer P abhängig von der gemessenen Spannung der Batterie B festgelegt wird. Bei dieser Weiterbildung ist also während der ersten Wartezeit, also unmittelbar bei Beginn des Parkens, die Taktfrequenz Q-Q-Q der Betätigung des Betriebsschalter A nicht immer gleich. Statt dessen hängt diese Taktfrequenz auch vom jeweiligen aktuellen Aufladezustand der Batterie B ab, indem z.B. sofort nach dem Parken eine Stromversorgungsweise benutzt wird, die der zweiten oder einer noch späteren Wartezeit entspricht - wobei dann in noch späteren Wartezeiten die Taktfrequenz Q-Q-Q evtl. noch weiter vermindert werden kann.A deep discharge of battery B can be avoided with even greater reliability by not letting the first waiting period begin again until the battery of the motor vehicle has been sufficiently recharged. During waiting times, for example from the second waiting time, the voltage can at least occasionally of the battery B can be measured, the pause time P being determined as a function of the measured voltage of the battery B. In this development, the clock frequency QQQ of the actuation of the operating switch A is not always the same during the first waiting time, that is to say immediately when parking begins. Instead, this clock frequency also depends on the current state of charge of the battery B, for example by using a power supply mode immediately after parking that corresponds to the second or a later waiting time - the clock frequency QQQ then possibly being reduced even further in later waiting times can be.
Um mit wenig Aufwand das erfindungsgemäße Verfahren durchführen zu können, kann das im Kfz K angebrachte Schließsystem - z.B. auch unmittelbar im Gehäuse des Empfängers E - einen Taktgeber F enthalten, welcher während der betreffenden Wartezeiten den Betriebsschalter A getaktet betreiben soll.In order to be able to carry out the method according to the invention with little effort, the locking system installed in the motor vehicle K - e.g. also directly in the housing of the receiver E - contain a clock F, which should operate the operating switch A clocked during the relevant waiting times.
Um ein wenig Aufwand erforderndes Beispiel für den Aufbau eines solchen Taktgebers F zu nennen, sei darauf hingewiesen, daß der Taktgeber F z.B. ein Flipflop enthalten oder darstellen kann. Der Taktgeber kann aber z.B. auch ein elektronischer Zähler, eine Uhr o.dgl. sein.To give an example of the construction of such a clock F which requires little effort, it should be pointed out that the clock F e.g. can contain or represent a flip-flop. The clock can, e.g. also an electronic counter, a clock or the like. be.
Um nicht in späteren Wartezeiten die Frequenz des Taktgebers F ändern zu müssen, kann die spätere Verringerung der Taktfrequenz Q-Q-Q, also die spätere Verlängerung der Pausendauern P, auch dadurch erreicht werden, daß der Taktgeber F einen elektronischen Frequenzuntersetzer enthält.In order not to have to change the frequency of the clock generator F in later waiting times, the subsequent reduction in the clock frequency Q-Q-Q, that is the later extension of the pauses P, can also be achieved in that the clock generator F contains an electronic frequency reducer.
Um mit wenig Aufwand eine zuverlässige, von der Taktung der Stromversorgung B des Empfängers E unbeeinträchtigte Stromversorgung des Taktgebers F zu bieten, kann der Taktgeber F einen Speicherkondensator enthalten, welcher eine, zumindest bis zur nächsten Betätigung des Betriebsschalters A nötige, Betriebsenergie zum Betreiben des Taktgebers F speichert. So kann man eine eigene ständige direkte Stromversorgung I des Taktgebers F vermeiden, vgl. die gestrichelt in der Figur 2 angegebene direkte Stromversorgung I des Taktgebers F. Statt dessen kann die Stromversorgung des Taktgebers F dann auch über den Betriebsschalter A erfolgen.In order to provide a reliable power supply for the clock generator F, which is unimpaired by the timing of the power supply B of the receiver E, the clock generator F can contain a storage capacitor which, at least until the next actuation of the operating switch A, requires operating energy to operate the clock generator F saves. So you can have your own permanent direct power supply I of the clock F avoid, cf. the direct power supply I of the clock generator F indicated by dashed lines in FIG. 2. Instead, the power supply of the clock generator F can then also take place via the operating switch A.
