Definitions

  • the invention relates to a method for individualizing and synchronizing a control device for the central locking and anti-theft device of a motor vehicle, which is equipped with a receiver for the reception of wirelessly transmitted, encrypted function commands and also a microprocessor, a memory, a non-volatile memory, a pseudo Random number generator, a counter and a control command output contains.
  • Keys are used for remote control of door locks on motor vehicles, in which a transmitter for wireless transmission of encrypted function commands is installed.
  • a receiver is arranged in the motor vehicle, which can decrypt the transmitted data and convert it into control signals.
  • it has already been proposed to change the coding continuously (DE-OS 34 06 746 and 35 29 882).
  • it is necessary that the transmission takes place in both directions and that the transmitter must also be assigned a receiver and the receiver must also be assigned a transmitter.
  • This method does away with any documentation and labeling effort, but it is not ensured that key data stored in the key is accidentally transmitted on the production route to the receiver of a lock that does not mechanically match the key. As a result, mechanical and electronic individualization and synchronization fall apart and the affected key lock system is unusable. In addition, there is a risk that the key data stored in the key may be transmitted, read out and later misused during the manufacturing process without authorization.
  • the method according to the invention differs from the method according to patent application DE 42 01 568 in that the characteristic data for the individualization and synchronization of the control unit is carried out wirelessly by means of the motor vehicle key containing the characteristic data, the characteristic data being hidden from the operating and service personnel and any manipulation itself by " Insiders ". In addition, additional hardware and software expenditure for initializing the control devices in the manufacturing process is eliminated.
  • the control device 2 for the central locking and anti-theft device is arranged in the motor vehicle and contains a receiver, a microprocessor, a memory, a non-volatile memory, a pseudo-random generator, a counter and a control command output.
  • the pseudo-random generators in the key and control unit can be implemented either in terms of circuitry or software.
  • an initialization command from the production computer 3 initiates primary synchronization by means of a serial interface.
  • the microprocessor of control unit 2 is sensitized to the recording and storage of the characteristic data.
  • the initialization command also tells control unit 2 which data storage location is to be used (key number).
  • the required number of telegrams for the wireless transmission of the entire characteristic data record can then be sent. It can be provided in the program that the complete characteristic data record must be sent at least twice and that a data comparison is carried out internally. The data are only stored in memory if they match.
  • the key / control device system is set up for wireless transmission of the coded control commands for central locking and theft protection.
  • a successfully completed primary synchronization is indicated by a reply via the serial interface. If no match is found, the primary synchronization process is repeated until valid characteristic data have been determined (FIG. 2).
  • a secondary synchronization may be necessary. Only new change code data have to be transmitted.
  • the secondary synchronization is initiated by a special initialization procedure or a special data telegram and can then be initiated by a special actuation of the key or by controlling the control unit independently of the key. You can use a contact in the door lock or a specific position of the ignition key. The data storage space that is to be occupied now results from the fixed code portion that key 3 sends in the data telegram.
  • the control unit 2 now expects a number of data messages, which it evaluates.
  • the change code is generated as a result of this evaluation.
  • the characteristic data which the control unit 2 now receives with the next data telegram are compared with the determined change code and the already known fixed code.
  • the change code received matches the change code expected from the determination, it is stored in a non-volatile storage medium, at a memory location assigned via the fixed code.
  • Successful secondary synchronization is indicated by the execution of the function command contained in the data telegram.
