Definitions

  • the invention relates to a device for testing the Authorization to use access control facilities, in particular locking devices for vehicles with an access-side control device with a Memory area for a secret code, one user key device that a Transponder with a memory area for storing a secret codes, contains, and comparison means in the Control device for determining the release authorization required for the access device, such that the information sent by the transponder with one in the control device by the secret Code specified default information is compared and that an approval of the Access takes place.
  • Such devices for testing the Authorization to use access control facilities that of an access control device and a key set up by the user are made of known in practice.
  • Modern key facilities get central Element a transponder coupled to a chip, which with electromagnetic excitation User code information, for example in the form of a Number sequence, sends out.
  • the control device compares whether the Transponder sent out in the key device User code information to an authorized user lets close or not. Only if the authorized user, the control device gives the Access to the downstream components of the vehicle free, while in the other case access to the operation of the Vehicle is blocked. To the owner of each Identifying the key device as authorized is described in a so-called "learning process" of the key device transmit a secret code from the control device. After teaching the complete set of vehicle keys, of the user when he takes over the vehicle each key is therefore characteristic for the authorized vehicle user.
  • Devices of this type are for example from DE 4317119 C2 and DE 4435894 A1 known.
  • the invention has for its object a Device of the type mentioned at the beginning to develop that automatic teaching of a re-or Replacement key by the user himself protection against abuse is made possible.
  • the means of the invention can in one Spare parts center with a requested replacement key release information can be preprogrammed.
  • the Key facility will be the requestor Vehicle users are then immediately available posed. This can then be the new key device without special aids or procedures and without Auxiliary staff automatically to the control device let learn. In this way, an increased Realize service friendliness. Especially in Regions with a thin dealer network or where keys are lost is on vacation the use of the invention Device advantageous.
  • the device according to the invention offers a large one Safety when teaching new key devices a control unit because by checking one vehicle-specific release information in the additional storage area of a new one Key facility ensures that a new one Key device only from the control device one certain vehicle can be taught by the one for which it has the release information.
  • the authorization to learn is checked by those already present in the control device Means of comparison that of the key device received release information with a requested Compare release information.
  • the drawing gives an overview of the use of the additional provided according to the invention Storage area in the key facility for the Filing of release information that is required for teaching a new key device should be required.
  • a first representation (1) is a Key device B of the device according to the invention shown.
  • the key device B includes one Transponder with a transponder coil T and a first one Memory area SP1 for the secret code for one usual access authorization procedure is provided.
  • a second memory area is SP2 available. In both memory areas are SP1 and SP2 At this time, no information has been saved.
  • a device C of a spare parts center which among other things contains a database or has access to one.
  • the database contains storage areas SC 1 -SC n , in which vehicle-specific information of all vehicles for which this spare parts center is responsible is stored.
  • vehicle-specific information of all vehicles for which this spare parts center is responsible is stored.
  • it is assumed that it is separate secret information.
  • openly accessible information such as the control unit identification numbers can also be stored.
  • the device C of the spare parts center also has means (not shown) for transmitting the stored secret data or, in the case of non-secret stored data, means for encrypting and transmitting the data.
  • the spare parts center receives the from a customer Request for another key facility for a Vehicle.
  • the Device C of the spare parts center which saved Information belongs to the vehicle for which a new one Key facility is requested.
  • device C transmits this or one of them generated release information M2 to a Key device B, which has not yet been a vehicle is assigned and the two memory areas SP1 and SP2 does not yet contain any data.
  • the key device B stores the received one Release information M2 in its additional Memory area SP2.
  • the key device B which in the second representation (2) again with the Information M2 occupied memory area SP2 is shown, can now be sent from the spare parts center to the customer be handed over.
  • the above is again described key device B shown.
  • a vehicle FZ is indicated here by a rectangle, at its control unit the new key device B should be taught.
  • This control unit is in the Vehicle FZ shown and labeled A.
  • the Control unit A has at least one Memory area SP3, in which the secret code for checking the usage authorization has been filed. Furthermore it has a comparison means V and not indicated means for the transmission of data.
  • the exemplary embodiment is a second memory area SP4 provided in which another secret information is filed. Additionally or alternatively, a Storage area for storing a PIN number to be available.
  • the key device B which the customer of the Spare parts center was handed over and now over has a secret release information M2, reads this Information from their additional memory area SP2 and transmits them, as indicated by an arrow, to the control unit A of the vehicle FZ.
  • the key device B stores the received one secret code M1 in the first memory area SP1 of the Transponders, as can be seen in illustration (5).
  • the key device B is now at the control unit A of the vehicle FZ is taught and can by the user as proof of the authorization to use the vehicle be used.
  • a additional memory area SP4 in control unit A provided in which one of the release information in the additional memory area SP2 of the key device corresponding information is stored.
  • secret information for the Authorization to teach in also uses the PIN number or the secret code for normal Access authorization itself.
  • Another alternative is as mentioned earlier, the use of open accessible information like that ECU identification number, if this first be encrypted.
