Definitions

  • the invention is directed on the one hand to a locking device of the type specified in the preamble of claim 1 and on the other hand to a device for coding an electronic key of the locking device in accordance with the preamble of claim 6.
  • a random fixed code is programmed into the electronic key. Additional interface components are required for this. In addition to these additional interfaces, components for signal processing and electronic protective measures in the electronic key are also required.
  • the relevant components for code determination e.g. B. a random number generator, are integrated in the interior of the key, for which special assembly measures, a corresponding space for their arrangement and cumbersome logistics are required.
  • the coding program is entered via a separate input port. For this one uses z. B. on the circuit board provided programming contacts, so-called pads, which are contacted by means of needles. For this purpose, the circuit board in the housing of the key must be accessible, which is why the coding must be carried out on a key that has not yet been fully assembled in the housing.
  • This known key can only be completed after it has been encoded.
  • Locking devices are also known where the coding of the key contactless inductive, by infrared light or by radio. Although this can be done with a fully assembled key, it also requires additional interface components, components for signal processing and associated protective circuits for the key. In the known locking devices, there is a short coding, which allows relatively few different coding for the keys. In practice it can easily happen that the same keys are available, which leads to problems.
  • the invention is based on the object the task of developing an inexpensive locking device of the type mentioned, which allows a space-saving structure of the key and allows easy and quick coding of the fully assembled key with a large variety of coding;
  • the invention is based on the object of disclosing a device for coding the electronic key of the locking device, which enables tamper-proof coding. This is achieved according to the invention by the measures specified in the characterizing part of claims 1 and 6.
  • the essence of the invention according to claim 1 is that the coding of the fully assembled key is carried out by a purely mechanical "morse-like" pressure actuation of an already existing (function) key of the key.
  • the coded key is then used to code the associated electronic lock in a known manner, which is done wirelessly, preferably by electromagnetic means.
  • the components necessary for the transmission operation are also used for coding the key.
  • the electronic key comprises at least one function key, which in the invention is also used as an input port for initiating the coding program. If the key should have several keys for the transmission mode, several keys can also be used as an input port for the coding.
  • the coding is therefore carried out by a defined actuation of the key or keys. Only one coding program with an activation mode is required in the key, while the code determination is external and can be entered by pressing the appropriate key.
  • the keyed-in code data only need to be activated in the key-side data acquisition mode that is then activated to be saved.
  • the peculiarity of the invention is thus "one-touch programming of the code via the given function keys of the electronic key".
  • the keying program can be of any length and therefore allows an unlimited variety of codings. All keys can therefore have a different code from one another.
  • the locking device according to the invention is used in a vehicle 10, but could also be implemented in other objects.
  • the locking device comprises two mutually cooperating device parts, namely an electronic lock 11 comprising several components in the vehicle 10 on the one hand and an electronic key 21 on the other hand, which can be operated by a vehicle user 20.
  • the key 21 interacts wirelessly with the lock 11, which in the present case is realized by an electromagnetic transmission 30 of the data.
  • the key 21 has a transmitter 22 and the lock 11 has a receiver 12.
  • the electronic key 21 has a housing 27, indicated by dash-dotted lines in FIG. 2, in the form of a flat plate which is reminiscent of a "check card".
  • the key 21 is assembled according to the invention with all its components in the housing 27, the most important components being indicated schematically in FIG. 2.
  • the microprocessor 23 comprises a data memory 24 with a program and with memory locations for a freely selectable coding.
  • the program for encoding the key contained in the data memory 24 will be referred to in the following for short as “encoding program”.
  • the coding program initially includes a so-called “activation mode", by entering the key for coding becomes receptive. With this key, this activation mode is entered via the button 26. To do this, the button 25 must be pressed in accordance with the stored activation mode.
  • FIG. 4 illustrates a suitable sequence of operations using a time diagram in section 34.
  • the individual periods of the actuation phases of the button 25 are illustrated by the raised areas 31 of the binary curve 36, while the duration of the idle phases of the button 26 in between, where the button 25 is not actuated, are characterized by the lowered areas 32 .
  • Both curve areas 31, 32 are separated from one another by sharply time-limited transitions 33.
  • the duration of the pressure operations is in Fig. 4 with t1, t2 etc., while the duration of the rest periods 32 accordingly t1 ', t2 'etc. is marked.
  • all components of the aforementioned binary curve 36 can be used, both summatively and alternatively. First, there is z. B.
  • the actuation frequency that is, the time sequence of consecutive actuations 31 of the key 25.
  • the time period t of the individual actuations 31 serve as well as the rest periods lying in between t 'can be used for this.
  • the exact temporal position of the transitions 33 between the pressure actuations 31 and the rest times 32 can also be used as a criterion for the activation. This means that there are a large number of variables which lead to a correspondingly large variety of coding.
  • Fig. 4 it is assumed that the activation mode has been carried out in the time period denoted by 34. This is followed by a so-called "data recording mode", which is illustrated in FIG. 4 with the section which then follows and is identified by 35.
  • the individual code of the key is entered here and its code storage in the data memory 24 is initiated.
  • This data acquisition mode too 35 runs via a further, functionally normal actuation of the button 25.
  • the actuation and / or the rest phases 32 and / or the time limits of the transitions 33 are decisive for the code determination.
  • the actual code determination takes place exclusively outside of the key and is only transferred to the key 21 by a purely mechanical, "Morse-like" pressure actuation of the key 25.
  • this key 25 also serves for the later normal transmission operation 30 between the key 21 and the lock 11.
  • the electronic lock 11 has the following components, indicated in FIG. 1. This includes the aforementioned receiver 12, which outputs the signals 30 coming from the key 21 to a microprocessor 13 in the vehicle 10 and a data memory 14 integrated there. This evaluates the received signal 30. Prior to this, the coding characterizing the associated key 21 has of course been transferred from the key 21 to the lock 11 in the data memory 14 there, in a manner known per se.
  • the local battery 18 is expediently used as the energy store in the vehicle 10.
  • the vehicle 10 has a door 17 which can be held in its closed position by a lock mechanism 16.
  • a locking mechanism 16 can, for. B. consist of a trap that cooperates with a locking block on a pillar of the vehicle body.
  • the electric lock 11 also includes a locking device, which is not illustrated in more detail, and which act on the lock mechanism 16 and lock or unlock it.
  • a door handle 15 interacts with the lock mechanism 16, which is usually used manually by the vehicle user 20 to open the door 17. Opening the door 17 via the door handle 15 is only possible when the lock mechanism 16 is in its unlocked position. If the locking position is on the other hand, the door 17 can no longer be opened via the door handle 15.
  • the reversal of the links of the lock mechanism 16 between the locking and unlocking position can be electrical, mechanical or pneumatic way.
  • the locking mechanism 16 can be locked and unlocked from inside the vehicle, but this can be done from the outside using the electric key 21.
  • An additional mechanical key can also be integrated in the electronic key 21 for emergencies.
  • a lock cylinder (not shown in more detail) on a door of the vehicle 10 can mechanically transfer the locking mechanism 16 into the unlocking position or into the locking position.
  • the button 25 of the electronic key 21 is pressed.
  • the signal 30 then emitted comprises a data stream which corresponds to the specific coding of this key 21.
  • This transmission telegram is received by the vehicle-side receiver 12 and evaluated in the microprocessor 13 using the coding stored there in the data memory 14. If a correspondence between the received code and the stored code is found during this evaluation, the door-side lock mechanism 16 is reversed by command via a line 19.
  • the closed door 17 can be secured in its closed position or unlocked for the purpose of actuating its door handle 15.
  • the device 40 comprises a working member 41, which can be moved by a drive 43 in the sense of the double arrow 42.
  • the device 40 comprises a control program shown as a block 44, which exactly determines a sequence of movements of the working member 41.
  • the key 21 is completely prefabricated, the key-specific coding not yet being entered in the data memory 24. After assembly, the finished key can be tested for its trouble-free functional reliability. The key then comes to the coding device 40, which inputs a freely selectable coding exclusively by mechanically actuating the key 25, which is also decisive for the later function.
  • the electronic key 21 is placed with its housing 27 on a support 45 of the device 40 and brought into alignment with the working member 41 with its key 25. Then the control program 44 is started.
  • a stroke movement 42 of the working member 41 now begins, which corresponds exactly to the curve profile of the time diagram 36 shown in FIG. 4.
  • the working member 41 presses, in the manner of a plunger, the button 25, which is pressed in the sense of the actuating arrow 29 indicated in FIG. 3.
  • both the activation mode 34 and the data acquisition mode 35 determining the code are mechanically entered into the key 21.
  • the course of the curve in data recording mode 35 is of course individually matched to the respective key 21.
  • the mechanical control program 44 of the device 40 is varied accordingly.
