Method and device for localizing a transceiver device
First Claim
1. A method for localizing at least one mobile transceiver embodied as an ID generator in relation to a further transceiver device embodied as a base station, the method which comprises:
- outputting, with the base station, a request signal with at least one predefined item of threshold information for the ID generator;
receiving the request signal with the ID generator, measuring a field strength of the request signal, and comparing with the at least one item of threshold information transmitted along with the request signal; and
outputting an appropriate response signal with the ID generator, in dependence on the comparison.

Abstract
A method and a device for executing a method for localization of at least one mobile transceiver embodied as an ID generator, especially as a vehicle key, in relation to a further transceiver device embodied as a base station. A request signal with at least one item of threshold information for the ID generator is transmitted by the base station. The request signal is received, if at all, by the ID generator. The field strength of the request signal is measured and compared to the at least one item of threshold information transmitted along with it and a corresponding response signal being output by the ID generator depending on the comparison.

11. In a motor vehicle, a method for localizing an ID generator relative to the motor vehicle, which comprises:
-
outputting, with a base station mounted in the motor vehicle, a request signal containing at least one predefined item of threshold information for the ID generator;
upon receiving the request signal with the ID generator, measuring a field strength of the request signal, and comparing with the at least one item of threshold information transmitted along with the request signal; and
if appropriate in dependence on the comparing step, outputting a response signal with the ID generator and receiving the response signal with the base station for further processing.
