  • Theft protection system for an automobile and method for initializing the theft protection system
    Patent number: 6870459
    Abstract: A theft protection system for an automobile and a method for initializing the theft protection system transmit a challenge signal from a central control unit over a data line during the initialization of the theft protection system, after a starting signal has been received. Control units that are connected to the data line send back an identification which is stored in the central control unit. The extent of the control units tied into the theft protection system is thus fixed. During subsequent authentication operations, all of those control units must answer with their identification, before the automobile can be used. An electronically coded dongle is advantageously used as a control unit.
