Method and device for securing a vehicle against theft
First Claim
1. Method for securing a vehicle against theft, characterized in that at least one essential operational element of the vehicle can be switched between three operating states A, B and C and is switched between these operating states according to the following steps:
- a. the essential operational elements are switched into a substantially unrestricted operation-ready operating state A by an external usage authorization device independent of the vehicle over means for transmitting the authorization data, b. at least one essential operational element is switched into an operation-ready operating state B by an event-dependent circuit through at least one event for a period of time, the period of time depending on predefined operating parameters, c. either at least one essential operational element of the vehicle is switched after the passage of time for putting out of operation the vehicle into a non-operation-ready or restrictively operation-ready operating state C or the essential operational elements are switched before the passage of the time period into operation-ready operating state A according to method step a) by means of the usage authorization device via means for transmitting the authorization data.

Abstract
The invention relates to a method and a device for securing a vehicle against theft. According to the invention, at least one essential operating element (2) of the vehicle can be switched between three operating states A, B and C. An external authorisation device (3) switches the operating element into the unlimited operating state A. If a defined action (20) is carried out, for example the driver'"'"'s door is opened, the operating element is switched into the operating state B for a defined period of time. If authorisation information is transmitted during this time, the operating element is switched back to the operating state A. Otherwise, once this period of time has expired, the operating element is switched into the non-operational operating state C.

- 5. System for securing a vehicle (1) against theft by means for switching (3, 4, 5) at least one essential operational element (2i) of the vehicle (1), the means for switching (3, 4, 5) comprising at least one usage authorization device (3), at least one switching device (4) between specific operating states of the essential operational element(s) (2i) and means for transmitting the authorization data (5) between the usage authorization device (3) and the switching device (4), characterized in that the essential operational element(s) (2i) is(are) switchable between three operating states A, B and C, operating A permitting the essentially unrestricted operation of the essential operational element(s) (2i), operating state B permitting the operation, restricted by operating parameter P to a time period Z, of the essential operational element(s) (2i) and operating state C causing the blockage of the essential operational element(s) (2i), with the switching device (4) being connected over at least one operational connection (6) with at least one means each for detecting a switching event (20i).
