Antitheft lock for road vehicle with keyless operation has identification system allowing unlocking and engine start and has timers with different functions in control circuit

摘要

The lock operation procedure starts with a ''start refused, wait for new identification'' step (16) or a ''start allowed, switch to safety mode, wait for starting of engine'' step (17). This is followed by an ''engine running'' step (18). The ''start allowed'' step may be repeated (27). The system may move from the ''start refused'' step to the ''start allowed'' step on receipt of the proper identification (25). An identification module is connected to a control circuit with a timer for valid identification and a new validity timer, also a safety counter and a safety timer.
