Abstract:
A method for authorizing the use of a motor vehicle having a first and second antenna spatially remote from one another, includes emitting, from the first vehicle antenna, a first signal that is received by an identification transmitter antenna of a portable identification transmitter. The method also includes establishing at least one spatial component of a first electromagnetic field of the received first signal using an angle-resolving magnetic field sensor, emitting, by the second vehicle antenna, a second signal that is received by the portable identification transmitter antenna, and establishing at least one spatial component of the second electromagnetic field of the received second signal using the angle-resolving magnetic field sensor. The method also includes establishing an angle at least between the established at least one spatial component of the first electromagnetic field and the established at least one spatial component of the second electromagnetic field, and providing a first authorization signal for authorizing the use of the motor vehicle when the established angle exceeds a predetermined threshold value.

Claim (Index 16):
The method as claimed in  claim 1 , wherein the threshold value increased as a distance of the portable identification transmitter from the motor vehicle decreases, and wherein the distance is determined via a propagation time measurement between signals exchanged between vehicle and portable identification transmitter.
