CODE SIGNAL TRANSMITTER, ESPECIALLY FOR AN ANTI-THEFT SYSTEM IN A MOTOR VEHICLE |
摘要 |
A code signal generator has a transponder unit, which proves its authorization for releasing an immobilizer by means of a question-response dialog. The code signal generator has a remote control unit which transmits control signals for unlocking doors upon the actuation of a pushbutton. Both the transponder unit and the remote control unit have a single encryption unit, which is accessed by both units in order to encrypt the signals to be transmitted. |
