Definitions

  • the invention relates to an improvement of safety devices in a vehicle.
  • the invention is based on the special locking system defined in the preamble of claim 1, which by itself - EP-A2-395 596 is known.
  • an anti-theft device is actually described, in which the remotely controllable lock is only one of the components of the anti-theft device.
  • the control unit installed in the vehicle and the handheld transmitter each have their own memory, for example an EEPROM. If the hand transmitter sends a locking command - or a command to activate the anti-theft alarm system of the device - and the control unit received this locking command and accordingly controlled the locking, the memory of the control unit stores an acknowledgment signal that this has happened; in addition, the control unit then sends the acknowledgment signal back to the hand transmitter, which in turn stores the received acknowledgment signal in its own memory. In this way, the owner of the handheld transmitter should be able to prove to his car insurance company at any time later that it has been properly locked using the memory in the handheld transmitter if the vehicle has been broken into or stolen.
  • This known device also includes various display options, in particular according to column 3, lines 19 to 28, column 4, lines 6 to 13 and column 5, lines 1 to 11, which are controlled directly or indirectly by the control unit attached to the vehicle. It is not just a matter of switching on the headlights or the horn if the anti-theft device detects that the vehicle is being broken into.
  • signal lamps for example LED signal lamps, on the hand transmitter in order to indicate to the user of the hand transmitter, that the control unit really generated the receipt signal or that the receipt signal is now stored in the memory of the handheld transmitter and can serve as evidence for the motor vehicle insurance.
  • This state of the art assumes that the locks are really locked when the control unit installed in the motor vehicle properly confirms receipt of the locking command and thus the release of the locking command to the locking element, by generating the acknowledgment signal and even storing it in the handheld transmitter .
  • this known locking system does not actually perform its task reliably, namely to monitor whether the locks have really been locked properly: the locking system described there has the disadvantage that it also simulates the perfect locking when the control unit issued the bolt command in the direction of the bolt element, but nevertheless the bolt element no longer locked the lock due to some defect. E.g. then even the insurance using the PROM in the hand transmitter appears to prove that the vehicle has been locked, even though the locking element e.g. jammed and did not move into the locking position at all. In reality, this known locking system does not monitor fully automatically whether the locks in question have really been locked properly after the correct receipt of the locking command, but only whether the control unit issued the locking command and sent the acknowledgment signal. However, the invention monitors fully automatically whether the lock in question has really been locked properly.
  • Another disadvantage, which the invention additionally avoids, is present in this known locking system, even if the control of the position of its locking element is not defective, that is, even if its locking element is not jammed, for example:
  • optically displayed - acknowledgment signal in particular by a specially attached Lamps on the handheld transmitter or in the motor vehicle can more or less clearly recognize that the locking took place properly.
  • Such a display does not only require the additional effort, namely to attach such a lamp.
  • the invention thus also avoids this disadvantage that the person in question can insufficiently take into account the absence of the acknowledgment signal when getting used to it.
  • the invention allows the additional measures to be taken in accordance with this known document, so that the locking system designed according to the invention can additionally transmit the known acknowledgment signal and also store it in a PROM of the handheld transmitter.
  • the invention is not limited to the monitoring of remote locks of certain types of locks. Therefore i.allg. spoken of "locks” instead of "locks", because the invention relates to any lockable locks, for example also those which are always operated without any mechanical key, that is to say, for example, lockable exclusively by remote control Slider or closure members. It is only essential that the lock in question in its locked position prevents inadvertent opening of the lockable cover in question, for example in the event of wind, and that this lock can additionally be locked to protect against unauthorized and / or unintentional opening.
  • the motor vehicle should apparently contain its own transmitter, whereby the handheld transmitter can automatically recognize its respective distance from the motor vehicle from the transmitter field strength.
  • the person remote-controlling the lock can recognize by vibrating, that is to say by a warning signal, that the hand transmitter has not yet been properly operated to lock the motor vehicle.
  • the corresponding details about the electronics in the motor vehicle are not disclosed, which would be able to monitor fully automatically whether the locks in question were really properly locked despite receipt of the locking command.
  • a locking system which the locking system defined in the preamble of claim 1 in some respects is similar is by the - DE-A1-34 47 046 previously known.
  • the task of this known system is therefore only that its sensor should be able to detect whether the covers in question are already closed or still open, regardless of the state of its locks and, above all, regardless of the state of their locks.
  • the invention was initially developed for the remote-controlled locking system of a car, which automatically monitors the locking of the locks, that is, the locks or other lock-like locking elements of the covers of openings.
  • the invention should primarily monitor the locking of the locks of the car doors and the trunk lid.
  • the invention is not only suitable for the locking system of motor vehicles par excellence, but also for the locking system of other vehicles, e.g. for the fully automatic monitoring of the locking of the locks on the covers of the luggage compartment of an aircraft or a freight car or a ship's compartment.
  • the object of the invention therefore does not primarily relate to monitoring whether the covers in question have really been closed.
  • the invention actually does not primarily relate to monitoring whether the organs which trigger the locks of the locks which protect against unauthorized actuation of the locks have been reliably controlled.
  • the invention relates primarily to monitoring whether the relevant locking elements of such locks really reliably lock the lock and, first of all, the very conspicuous, displays that even get used to habits, if the locking with the hand transmitter was not carried out properly, while avoiding costly additional design work on the vehicle.
  • the invention allows, however, that in addition those other monitors described in the known documents mentioned are carried out.
  • the invention After leaving the vehicle - or after leaving the relevant space of the vehicle - the invention therefore automatically monitors by means of the sensor or by means of several such sensors whether the relevant lock or the relevant locks have really been locked after the remote-controlled locking.
  • This sensor can, for example, through a contact are formed, which is actuated by the locking element itself as soon as the lock is properly locked.
  • This sensor can also be a piezoelectric element, for example, which, controlled by the locking element in accordance with its position, generates a signal as soon as the lock is properly locked.
  • the control unit emits, for example, an unmistakable optical and / or acoustic failure signal, which is very noticeable for the person concerned, if the lock or the lock has not been properly locked.
  • the locking system shown in FIG. 1 is used to monitor the remote-controlled locking of the locks or locks in the motor vehicle doors T shown in FIG. 2, possibly also in the trunk lid thereof. These doors T and the trunk lid are covers for openings on the vehicle.
  • the lock in question contains - or contain the locks in question - in each case at least one locking element V, which in each case should prevent, or at least complicate, an unauthorized opening of the lock T in question.
  • the locking of the lock in question is triggered by a portable hand-held transmitter H, which can emit actuation signals C, namely, for example, ultrasound, infrared or radio signals C.
  • actuation signals C namely, for example, ultrasound, infrared or radio signals C.
  • the lock is assigned a movable locking element to lock it, cf. V, which can optionally lock and unlock the lock.
  • measures can be taken so that the lock in question is only finally locked when the cover in question, cf. T, closed and the lock is already in its locked position.
  • the invention can also be covers T in which the associated lock can in principle also be locked when the cover T in question is still open; then i. the cover in question can also be closed after its lock has been locked, after which this lock, because of its prior locking, e.g. or the like despite operating a door handle. - is no longer easy to open.
  • the locking system also has an electronic control unit S for remote control of the lock, possibly in addition to remote control of the locks itself, and possibly also for the control of auxiliary motors for moving the covers T.
  • This control unit S can also be used in a manner known per se serve to check codes if the actuation signals emitted by the hand-held transmitter H should have a code approved for the motor vehicle in question.
  • This control unit can also be constructed exclusively from discrete components, but also e.g. be formed by a processor with appropriate software.
  • the locking system also has a receiver E for receiving the actuation signals C, cf. Figures 1 and 2.
  • the receiver E consists e.g. from a photodiode if the handheld transmitter H, cf. Figures 1 and 2, optical actuation signals C emits.
  • the receiver E can also receive acoustic actuation signals C or by radio e.g. actuation signals C transmitted in the MHz range or in the GHz range.
  • these two components S and E of the locking system can be fitted anywhere in the motor vehicle, for example also in the door T or cover T thereof, cf. the figure 2.
  • control unit S As soon as the control unit S receives the corresponding control signal B via the receiver E, triggered by a corresponding actuation signal C, the control unit S sends a corresponding switching signal R as a locking command R to the control element A, which here is, for example, a coil A magnetically moving the locking element V. . Depending on the position L of the locking element V, the lock in question is locked or unlocked.
  • the locking system shown also has the sensor F, which detects the respective positional state L of the locking element V.
  • This sensor F can e.g. immediately feel the locking element V.
  • this sensor F can also indirectly determine the positional state L of the locking element V, e.g. by sensing the position of an extension of the locking element V, or by determining the position or the correlating state of parts driving the locking element V or of parts driven by the locking element V.
  • This sensor F sends its locking signal Y corresponding to the respective position state L to the control unit S, so that the control unit S detects the respective position state of the locking element V on the basis of the locking signal Y.
  • the control device S can thus automatically monitor whether or not the lock of the cover T was additionally locked correctly after leaving the vehicle, that is to say whether or not the relevant interior of the motor vehicle was protected against unauthorized actuation of the lock.
  • control unit S In the absence of the locking signal Y, the control unit S emits a warning signal W to one or more components - for example to the headlights and the horn - which are already attached to the vehicle for other purposes and whose actuation provides a striking display of the warning signal W even for one represents a person who operates the handheld transmitter H from the limit range of the handheld transmitter H.
  • a power amplifier can also be provided at the output of control unit S. Z inserted, which forwards the warning signal W with a high electrical power.
  • the control device S In order to offer the person remotely controlling the lock a conspicuously perceptible warning if the relevant lock or locks of the motor vehicle have not been properly locked despite a corresponding actuation of the hand transmitter H, the control device S according to the invention gives the warning signal W when there is no locking signal Y. from.
  • This warning signal can activate a signal generator, e.g. the car's horn, and / or e.g. the hazard warning system of the motor vehicle, and / or another signal generator that is difficult to overlook or difficult to ignore, in order to emit an unmistakable failure signal to the person concerned.
  • the sensor F thus serves to determine whether the lock in question is really in the locked state after the actuation signal C has been sent, by this sensor F outputs a corresponding locking signal Y to the control unit S.
  • This locking signal Y thus serves as an acknowledgment for a successful locking of the locks.
  • this locking signal Y fails to appear, although the control device S, caused by the receiver E, controlled the locking element by means of the control element A, the control device S emits a warning signal W, which in turn actuates a signal generator element which is difficult to overlook in order to signal the person with a failure signal to warn.
  • the invention informs the user by means of the warning signal W. Then this user can e.g. take advantage of the opportunity to use other means, e.g. with a mechanical key to lock completely.
  • the warning signal W or the failure signal triggered by it can also cause that person to try the remote-controlled locking again, e.g. by moving closer to the vehicle and then sending an actuation signal C again.
  • the invention thus avoids the disadvantage of other locking systems described above that thieves can easily penetrate into the motor vehicle if the person concerned accidentally fails to get used to the fact that after the remote control of the locking system there was no acknowledgment signal indicating positive locking.
  • the invention allows additional measures - e.g. according to the known writings mentioned - are made so that the locking system designed according to the invention can additionally send out that acknowledgment signal.
  • the locking signal Y can be a short signal Y that only occurs at the beginning of the locking, instead of being a continuous signal Y for the entire duration of the locking.
  • the control unit S can output the warning signal W with a delay.
  • the control device S can thus e.g. issue the warning signal W if the sensor F is within e.g. No locking signal Y was emitted 1 second after the hand transmitter H was actuated.
  • the delay can e.g. can be achieved by the above-mentioned monostable flip-flop - or also by a different type of delay element, also switched differently, namely e.g. also by suitably designed software of a processor installed in the control unit S.
  • the warning signal W can actuate an optical and / or acoustic signal transmitter present in the vehicle.
  • this signal transmitter can also be an optical or acoustic signal transmitter that is already available for other purposes in the vehicle, that is to say, for example, a control unit for the high beams, indicators, horn or the signal transmitter of an anti-theft alarm system. If the warning signal W switches on the hazard warning lights and / or the vehicle horn, the owner of the handheld transmitter can be made aware of the improper locking in a particularly simple, eye-catching manner.
  • control unit S can carry out a self-test of the locking system from time to time and issue the warning signal W if an error occurs.
  • the self-test can be carried out in a particularly simple manner - e.g. when opening the cover T, when starting the vehicle engine and / or while driving - are carried out if the self-test represents a brief alternating back and forth between the locked and the unlocked state of the locking element V which is monitored according to the invention.
  • unlocking can e.g. the actuation signal C triggering the unlocking trigger the self-test.
