PCT No. PCT/DE96/00942 Sec. 371 Date Dec. 3, 1997 Sec. 102(e) Date Dec. 3, 1997 PCT Filed May 30, 1996 PCT Pub. No. WO96/39317 PCT Pub. Date Dec. 12, 1996A drive lock includes a security control unit and an engine control unit that is ready for operation only when the engine control unit has received from the security control unit an encoded release code that matches a predetermined reference code. The engine control unit has storage devices into which it can enter a reference code. On receipt of a release code, it checks on whether a reference code is present in the storage devices. If there is a reference code matching the release code, the engine control unit makes itself ready for operation. If there is no reference code, it accepts the release code into the storage devices as the reference code. |
