<p>The method involves emitting two temporally independent electromagnetic signals (LF1,LF2) by two different spatially arranged onboard antennas (ANT1,ANT2). The components of the respective field strength vectors of emitted electromagnetic signals of two antennas are measured. The components are arranged with each other at right angles, by a mobile identification transmitter (IDG). The measured components of the respective field strength vectors are combined to verify the degree of parallelism of the respective field strength vectors. An independent claim is included for an arrangement for accessing and starting authentication of a mobile identification transmitter of a vehicle with an onboard transmitter.</p> |
