Definitions

  • the invention is based on the locking system defined in the preamble of claim 1, which e.g. can represent a central locking system for the door locks and for the trunk lock of a motor vehicle and which is known to the person skilled in the art from a large number of publications and prior uses.
  • a main problem of such methods is the avoidance of overreaches of the transmitter, which facilitate theft - occasionally also the avoidance of underreaches, which make remote control difficult or impossible.
  • the invention relates to this main problem, namely the reliable automatic adaptive adjustment of such a range, which complicates thefts or burglaries and / or ensures the convenient remote control of lockable locks.
  • the invention was initially for the special, in the - WO 90/14484 described unidirectional motor vehicle locking system developed when this uses transmitter signals transmitted by radio.
  • the invention is also particularly suitable for this.
  • the invention can in principle also be used in many other locking systems:
  • the transmitter signals can not only be transmitted by radio, e.g. in the kHz to GHz range, but also optically, e.g. in the infrared range.
  • a preferred example, in which the invention is applicable, is a motor vehicle locking system, namely a remote-controlled motor vehicle central locking system. Then the emitted transmitter signals are received by the receiver, which is, for example, hidden in the passenger compartment of the motor vehicle.
  • the locking system can also be used for other objects, including other types of vehicles and, for example, also for buildings and garage doors.
  • the transmitter can also - but does not have to - transmit digitally coded transmitter signals, rather than analog coded transmitter signals, as soon as the user transmits the transmitter, e.g. an actuation button of the same to open - possibly also to close - the cover (door, trunk, etc.) of the opening.
  • the receiver compares the received code with digits previously stored in the receiver, e.g. with bits previously stored in a binary memory of the receiver before it operates the locks of the locks concerned.
  • any code can be used for the transmitter signals. So it can e.g. is a fixed code, which remains unchanged from operation to operation. However, it can also be an interchangeable code, which makes theft or burglary particularly difficult by changing the code from actuation to actuation according to certain rules or algorithms individually assigned to the relevant locking system. - In itself, however, the transmitter signals need not represent any code in the invention; you can e.g. also represent a single, more or less long-lasting impulse.
  • the receiver can either unlock and lock the lock in question - or together the locks in question - or only unlock or only lock. Perhaps the receiver can not only control the locking remotely, but also open and / or close the covers (doors, lids, etc.) of the openings in question by the receiver in an appropriate, staggered manner controls both the locking elements and an auxiliary motor which moves the relevant covers.
  • the invention can also be a so-called bidirectional locking system, in which a dialogue takes place between the transmitter and the receiver as soon as a user operates the transmitter. But it can also be a more or less strictly unidirectional locking system, in which there is no dialogue between the transmitter and the receiver and the reliable automatic adaptive adjustment of the range seems particularly difficult, for example in the - WO 90/14484 Unidirectional vehicle locking system described.
  • Both figures therefore show an automotive locking system according to the invention which can be remotely controlled by transmitter signals I, in which e.g. is a central locking system for several locks L of several covers T of the openings.
  • the user operates a portable transmitter S, shown in both figures, which serves as a key S.
  • the transmitter S sends its transmitter signals I to the receiver E installed in the motor vehicle, for example triggered by actuation of a corresponding pushbutton of the transmitter S.
  • the transmitter signals I can be, for example, UNLOCK transmitter signals I which use the control signal Z to unlock the relevant one or them Initiate locks L, and / or by LOCK transmitter signals I, which initiate the locking of these locks L by means of the control signal Z, but only in each case if the receiver E is within range W of the transmitter S.
  • the transmitter signals I solve via the input stage A of the receiver E and via the output stage R of this receiver E a control signal Z only shown in FIG.
  • This output stage R can be, for example, a relay R, or another type of control circuit R which supplies sufficient current strengths and which controls the locking element B by means of the control signal Z, which locking element B can be, for example, a bolt B blocking the lock L and movable by magnetic coils.
  • the receiver E thus controls, caused by the transmitter signals I, the locking element B of at least one lock L of at least one cover T, e.g. the locking element B of the lock L of the driver's door T of the motor vehicle, - preferably only after checking the access authorization of the user of the transmitter S, namely e.g. after a comparison of the code received by the receiver E with corresponding digits previously stored in the receiver memory M.
  • both figures show only a single lock L, the locking element B of which is actuated by means of the transmitter signals I.
  • the user can control the interlocks B remotely by means of a transmitter signal I, or by means of a more or less precisely prescribed series of transmitter signals I, - for simplicity, however, only "transmitter signals I" are used here.
  • the lock L can be unintentionally unlocked again - especially if it is radio transmitter signals I, because radio waves due to their propagation characteristics - in contrast to infrared signals - also walls and even can also easily penetrate a pocket of the user and therefore an accidental triggering of the transmitter signals I can take place even when the transmitter S is already plugged in, even out of a house and around corners.
  • the range W of the transmitter S can, however, in itself also be subject to temporary fluctuations which occur during the operation of the transmitter S. These fluctuations in the range W are based e.g. on different external conditions such as temperature, or on the decrease in battery voltage in the transmitter S.
  • Another sensitive point is the tolerances of the components in the manufacture of the locking system, or the scattering caused by these tolerances in the transmitter power and the reception sensitivity of the receiver E.
  • a maximum range W - or a corresponding maximum transmitter power or a corresponding maximum reception sensitivity - should be set as reliably as possible between the transmitter S and the receiver E, which safe opening and closing of the vehicle only within a narrowly definable distance W to the vehicle from e.g. 10 m +/- 2 m allowed.
  • the receiver E constructed according to the invention namely automatically and adaptively adjusts the sensitivity of the receiver E and / or the transmitter power accordingly. This is because the invention adopts the knowledge that the range W of the transmitter S can be adjusted again and again to its optimal setpoint value if the transmitter power and / or the sensitivity of the receiver E automatically and adaptively correspondingly more or less regularly or less regular, direct or indirect measurements of the respective maximum range W is adjusted.
  • the receiver E constructed according to the invention monitors - at least from time to time, e.g. immediately as part of each actuation of the lock of the lock L in question - a physical quantity of the received transmitter signals I, e.g. their performance or their field strength.
  • the receiver E cf. the figure 2, e.g. in addition to its input stage A, or e.g. within this input stage A - the unit V, which can also be used as a device V for monitoring that variable - e.g. for monitoring the received field strength of the transmitter signals I - and as a device V for adjusting the maximum range W, that is to say for adjusting the sensitivity of the receiver E.
  • a - directly or indirectly - a physical variable, for example the transmitter power, of the transmitter S is measured more or less regularly and, depending on this, the sensitivity of the receiver E and / or the transmitter power is adjusted so that a good definable reception range as maximum range W results.
  • That unit V of the receiver E therefore measures that size at least indirectly and regulates e.g. the sensitivity of the input stage A through a corresponding feedback indicated in FIG. 2 - perhaps even without additional transmitter power - e.g. in the manner described below. Even if that unit V only adjusts the reception sensitivity of the receiver E, but not additionally the transmitter power, the next time the transmitter S is operated, i.e. the next remote control, the range W is optimally adapted - also to the respective state of charge of the transmitter battery S and even any tolerances and aging of all components of transmitter S and receiver E.
  • the adaptive adjustment according to the invention thus - at least from time to time, if not continuously with each actuation of the transmitter S - adjusts the range W for the next actuations of the transmitter.
  • the range W is thus sufficiently large to enable a user of the locking system to unlock the vehicle Z as soon as he approaches his vehicle.
  • the reception area is limited enough to ensure that the user no longer unintentionally actuates the locking of his motor vehicle by accidentally actuating the transmitter S away from the motor vehicle.
  • a fairly precise, automatic and adaptive optimization of the range W is possible, for example, in that the receiver E - for example by means of intermediate storage of several values of the size determined by its unit V in its receiver memory M - determines an average of several values corresponding to the monitored size and the range W is adjusted according to the mean value. Then the receiver E can, for example, adjust the sensitivity of its input stage A according to the average found. Further measures for adjusting the sensitivity of the receiver E and / or the transmission power of the transmitter S will be explained later.
  • transmitter signals I are used, which not only allow the locking itself to be controlled with a direct line of sight between the transmitter S and the receiver E, but above all also without a direct line of sight and even through walls and around Obstacles around, namely when the transmitter signals I are transmitted by radio, that is to say have radio frequencies.
  • the transmitter S can even send out the MESS transmitter signal I or the MESS transmitter signals I each time after sending out a transmitter signal I used for opening , in which case the unit V can optimize the setting of the maximum range W each time.
  • the MESS transmitter signals I can form a plurality of measurement pulses I which the transmitter S emits in succession at certain intervals, the size which the unit V monitors, e.g. represents the power curve or field strength curve immediately before, during and / or immediately after opening the cover T, and this unit V subsequently adjusts the sensitivity of the receiver E accordingly.
  • the MESS transmitter signals I can in themselves also represent simple pulses which are emitted, for example, at constant intervals. However, security against unauthorized unlocking can be increased by making it even more difficult for strangers, by recording the transmitter signals emitted by the transmitter and by later unauthorized transmission of these recorded transmitter signals, in order to unlock the lock: a locking system whose UNLOCK transmitter signals I in coded is particularly suitable Shape - preferably according to one Alternating code - are broadcast, but then the MESS transmitter signals I are then transmitted in coded form.
  • the time intervals of the MESS transmitter signals I and / or the pulse shape of the MESS transmitter signals I should preferably each correspond to a fixed — or likewise changing — code assigned to the transmitter S in question.
  • the receiver E only unlocks the lock L concerned, as long as not only the received UNLOCK transmitter signal I corresponds to the code assigned to it, but also the received MEASURING transmitter signals I correspond to the code assigned to them.
  • This variant of the invention allows additional conditions to be set for unlocking, for example the condition described in more detail below, that at least one pulse of the received MESS transmitter signal I must have a minimum field strength - otherwise the receiver E will not unlock the relevant one Castle L.
  • the transmitter S can also contain a transmitter memory N.
  • This transmitter memory N causes the transmitter S, in the seconds after the transmission of a transmitter signal I serving to open, to transmit one or, at intervals, several, MESS transmitter signals I.
  • the transmitter memory N can e.g. be formed by a counter or timer or clock, in which case this transmitter memory N can then cause the transmitter S to transmit within the seconds after the ENTRIEGEL transmitter signal I - e.g. to send out a series of short MESS transmitter signals I within 20 seconds.
  • the receiver then does not even need to evaluate all of the MESS transmitter signals I sent:
  • the receiver E is connected to a sensor K, which is attached, for example, in the door handle G and responds to touch by the user and which thereby recognizes the opening of the cover T or the actuation of the door handle G of the cover T.
  • a sensor K which is attached, for example, in the door handle G and responds to touch by the user and which thereby recognizes the opening of the cover T or the actuation of the door handle G of the cover T.
  • the range W can be optimized automatically and adaptively particularly precisely if the distance between the transmitter S and the receiver E is defined fairly precisely by means of the sensor K during the MESS transmitter signals I, and in particular if the MESS transmitter signals I additionally last a total of several seconds represent a continuous series of short measuring pulses I - whereby because of the then particularly short distance of the transmitter S from the door handle G or from the receiver E, the transmitter powers can even be particularly low during this monitoring:
  • the receiver E additionally has the sensor K, which detects the opening of the cover T, or the touching or actuation of a corresponding handle G of the cover T, and then emits a sensor signal C
  • the receiver E can also measure that size alone evaluate the relevant - or those few relevant - MESS transmitter signals I which the receiver E receives immediately before, during and / or immediately after the sensor signal C occurs; -
  • the receiver E can then not only adjust a "second" range W (2) which corresponds to the maximum - e.g. 1 m - distance of the transmitter S from the receiver E during the occurrence of the sensor signal C corresponds, but also that first, comparatively much larger - e.g. Adjust the 10 m range - range W, from which the receiver is ready to provisionally recognize an UNLOCKED transmitter signal I as such.
  • the receiver memory M then does not need to evaluate the size of all received MESS transmitter signals I, but only the size of at most those few relevant MESS transmitter signals I which it receives approximately during the occurrence of the sensor signal C.
  • the receiver E can even be constructed in this way, cf. the AND gate & in the output stage R of the receiver E in FIG. 2, that the control signal Z for unlocking the lock L is only emitted when both the sensor signal C and - more or less - the MEASURING transmitter signal I at the same time acts on the output stage R via the input stage A.
  • the relevant size of the MESS transmitter signal I occurring during the sensor signal C then causes the unit V to adjust the range W in advance for the next remote control of the locking system.
  • the receiver E does not unlock the lock L immediately after receiving the UNLOCK transmitter signal I, but rather that Lock L unlocked after receiving ENTRIEGEL transmitter signals I only if the measurements of the relevant size (e.g. field strength) of the additionally transmitted MESS transmitter signals I showed that the currently received ENTRIEGEL transmitter signal I, based on the currently correct SETPOINT of the adjustment of the maximum range W , obviously must have been transmitted within this correct maximum range W; - Otherwise, the lock L in question remains locked.
  • the relevant size e.g. field strength
  • the receiver E can also be constructed or dimensioned in such a way that it only unlocks the lock L after receipt of an UNLOCK transmitter signal I if at least a single one of the currently additionally received measurement pulses I has a greater field strength than the value for the maximum range W stored earlier, perhaps days or months ago.
  • the receiver E can also be constructed or dimensioned differently: it can to do this, after receiving an ENTRIEGELsendersignalals I, even if this ENTRIEGELsendersignal I is still too small in size, initially unlock the lock L in question for a waiting period, for example a few seconds, for example for 20 seconds. Subsequently, however, the receiver E immediately locks the lock L in question again, i.e. after this waiting period has expired, unless by then the size of at least one of the MESS transmitter signals I measured by it has exceeded the limit value which corresponds to a target range W that was previously valid for it.
  • the lock L in question is first temporarily unlocked, but locked again quickly, if not at least one of the currently additionally received measurement pulses I has a size (e.g. field strength) which is greater than that used to be - perhaps days ago or Months - corresponds to the stored setpoint. See the not pre-published - European patent application 91 103 518.6.
  • the receiver E can then also contain the sensor K and lock the lock L in question only after the waiting period has expired, if the sensor signal C does not occur in the receiver E by then and if until then the size of at least one of the currently received, relevant MESS transmitter signals I measured by him is additionally above the limit value, which of the valid ones - first or second - TARGET range corresponds to W. If the measured quantity is above the limit value, ie if the receiver E does not lock the lock L in question again, but leaves it in the unlocked state beyond the waiting period, then the receiver E can also adjust the range W again.
  • the invention permits a further route for a particularly precise automatic and adaptive — and then particularly precise — optimization of the — then again “second” range W by means of a precise definition of the distance from the transmitter S to the receiver E during the transmission of MESS transmitter signals I , Then the transmitter powers can even be particularly low during monitoring:
  • the transmitter S can form a structural unit S together with the ignition key, the transmitter S transmitting one or more MEAS transmitter signals I precisely while the ignition key S is in the ignition lock .
  • the receiver E monitors the relevant size, or the time profile of the relevant size, of the MESS transmitter signals I received from the inserted ignition key and accordingly adjusts the first associated with the UNLOCK transmitter signals I - and / or LOCK transmitter signals I - according to the definition given above "and possibly also” second "range W. You can also design the receiver E and the transmitter S so that each time (only) while the ignition key is inserted in the ignition lock, the receiver E causes the transmitter S to be temporary to send out the MESS transmitter signals I in order to then adjust the relevant range (s) W accordingly.
  • a transmitter is particularly suitable for this purpose, which, as just described, can also be used as an ignition key.

    - le récepteur (E) ajuste de nouveau cette portée (W) de consigne en fonction de la grandeur mesurée de ce signal de mesure (I) actuel, reçu ensuite, pour le cas où il ne verrouille pas de nouveau la serrure (L) correspondante, mais la maintient à l'état déverrouillé au-delà du délai d'attente.
  10. Système de fermeture pour véhicule automobile à clef de contact, suivant l'une des revendications précédentes, caractérisé en ce que
    - l'émetteur (S) et la clef du contact d'allumage forment ensemble une unité (S),
    - l'émetteur (S) émet un ou plusieurs signaux de mesure (I) quand la clef de contact (S) est enfoncée dans la serrure de contact, et
    - le récepteur (E) contrôle la grandeur correspondante des signaux de mesure (I) reçus de l'émetteur, ou le déroulement dans le temps de la grandeur correspondante, et ajuste en conséquence la portée (W) associée aux signaux (I) de l'émetteur.
  11. Système de fermeture suivant l'une des revendications précédentes, caractérisé en ce que
    - l'émetteur (S) contient un récepteur supplémentaire propre, ainsi qu'une unité d'ajustement destinée à ajuster sa propre puissance d'émission (S), et
    - le récepteur (E) contient son propre émetteur supplémentaire, qui émet un signal d'ajustement vers le récepteur supplémentaire, pour ajuster la puissance d'émission de l'émetteur (S).
  12. Système de fermeture suivant l'une des revendications précédentes,
       caractérisé en ce que
    - l'émetteur (S), au moyen de son unité d'ajustement (S) et au moyen du signal d'ajustement, ajuste sa propre puissance d'émission (S) à la puissance d'émission minimale (S) exigée par le récepteur (E).
  13. Système de fermeture suivant l'une des revendications précédentes,
       caractérisé en ce que
    - le récepteur (E) ajuste sa propre sensibilité (E) pour des signaux de déverrouillage (I) émis par l'émetteur, de telle façon
    * que le récepteur (E), si l'émetteur (S) est en dehors de la portée (W) ajustée pour les signaux de déverrouillage (I) peut effectivement recevoir clairement les signaux de déverrouillage (I), mais ensuite, malgré cela, ne déclenche pas le déverrouillage (Z), et
    * que le récepteur (E), si l'émetteur (S) est à l'intérieur de la portée (W) ajustée pour les signaux de déverrouillage (I), déclenche le déverrouillage (Z) après réception d'un ou de plusieurs signaux de déverrouillage (I).
  14. Système de fermeture suivant la revendication 13,
       caractérisé en ce que
    - le récepteur (E) ajuste sa propre sensibilité (E) pour des signaux de verrouillage (I), de telle façon que
    * le récepteur (E), même si l'émetteur (S) est en dehors de la portée (W) ajustée pour les signaux de déverrouillage (I), verrouille la serrure (L) correspondante, si le récepteur (E) reçoit de l'émetteur (S) un ou plusieurs signaux de verrouillage (I).
  15. Système de fermeture suivant l'une des revendications précédentes,
       caractérisé en ce que
    - l'émetteur (S) émet ses signaux de déverrouillage (I) avec une puissance nettement plus faible que ses signaux de verrouillage (I).
  16. Système de fermeture présentant plusieurs émetteurs (S) émettant des signaux (I) codés de façon différente entre eux et présentant une puissance d'émission différente entre eux, suivant l'une des revendications précédentes,
       caractérisé en ce que
    - le récepteur (E) comporte une mémoire (M), et
    - le récepteur (E) ajuste de façon différente d'émetteur (S) à émetteur (S), sa propre sensibilité en recevant un signal d'émission codé (I) ou après sa réception, lequel signal codé (I) contient un code de clef, identifiant l'émetteur (S) concerné, tandis que
    * le récepteur (E) enregistre dans la mémoire (M) ces valeurs de consigne optimales différentes des sensibilités qui sont associées aux différents émetteurs (S), et
    * le récepteur (E) ajuste chaque fois, en fonction de la valeur de consigne associée à l'émetteur (S) concerné, sa sensibilité propre (E) en recevant un signal d'émission codé (I) ou après la réception de ce signal codé (I), lequel signal codé (I) contient un code de clef, identifiant l'émetteur (S) concerné.
