Method and dveice for securing a vehicle against theft

摘要

The method for preventing a vehicle from being stolen comprises switching at least one operating element of the vehicle between three operating states. The operating element is switched into a first operating state which is operational in an unlimited manner by an external authorization device independent of the vehicle via devices for transmitting the authorization information. At least one operating element is switched into a second operating state that is operational over a defined period of time by at least one event in an event-dependent circuit. The period of time is dependent on pre-defined operating parameters. At least one operating element of the vehicle is switched to a non-operational or limited operation third state once the period of time has expired to stop the vehicle, or the operating elements are switched into the first operating state by the authorization device by elements for transmitting the authorization information before the period of time has ex expired. An independent claim is also included for a device used for preventing a vehicle from being stolen.
