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 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. An angle 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 is determined, and a first authorization signal for authorizing the use of the motor vehicle to the motor vehicle is transmitted by the portable identification transmitter when the established angle exceeds a predetermined threshold value.

Claim (Index 18):
A vehicle access system configured to authorize use of a motor vehicle, wherein the system comprises at least one first vehicle antenna and one second vehicle antenna, wherein the first vehicle antenna and the second vehicle antenna are located at a spatial distance from one another, and wherein the system is configured to:\n emit, from the first vehicle antenna, a first signal that is received by an identification transmitter antenna of a portable identification transmitter; establish, by the portable identification transmitter, at least one spatial component of a first electromagnetic field of the received first signal using an angle-resolving magnetic field sensor; emit, by the second vehicle antenna, a second signal that is received by the portable identification transmitter antenna; establish, by the portable identification transmitter, at least one spatial component of the second electromagnetic field of the received second signal using the angle-resolving magnetic field sensor; establish, by a computer in the vehicle, 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 transmit, by the portable identification transmitter, a first authorization signal for authorizing the use of the motor vehicle to the motor vehicle only when the established angle exceeds a predetermined threshold value.
