Abstract:
A method for authorizing the use of a motor vehicle by a portable identification transmitter is provided. According to the method, a first vehicle antenna emits a first signal and a second vehicle antenna emits a second signal. An identification transmitter determines at least one of the spatial components of first and second electromagnetic fields, respectively, of the first and second signals. The identification transmitter transmits a measure or a value for the at least one spatial component of the first electromagnetic field, and a measure or a value for the at least one spatial component of the second electromagnetic field to the motor vehicle. A computer determines an angle between the spatial components of the first and second electromagnetic fields. The motor vehicle transmits an authorization signal for authorizing use of the motor vehicle only if the angle exceeds a predetermined threshold value.

Claim (Index 18):
A non-transitory computer-readable medium comprising computer instructions executable by a processor to cause the processor to perform a method for authorizing use of a motor vehicle that has at least a first antenna and a second antenna, wherein the first antenna and the second antenna are at a physical interval from one another, by a portable identification transmitter that has an identification transmitter antenna, the method comprising:\n emitting, by the first vehicle antenna, a first signal that is received by the identification transmitter antenna; determining, by the portable identification transmitter, at least one of spatial components of the first electromagnetic field of the first signal; emitting, by the second vehicle antenna, a second signal that is received by the identification transmitter antenna; determining, by the portable identification transmitter, at least one of spatial components of a second electromagnetic field of the second signal, using an angle-resolving magnetic field sensor; transmitting, by the portable identification transmitter, a measure or a value for the at least one spatial component of the first electromagnetic field of the first signal and a measure or a value for the at least one spatial component of the second electromagnetic field of the second signal to the motor vehicle; determining, by a computer in the motor vehicle, an angle between the spatial component of the first electromagnetic field of the first signal and the spatial component of the second electromagnetic field of the second signal; and outputting, by the motor vehicle, an authorization signal for authorizing use of the motor vehicle only if the angle exceeds a predetermined threshold value.
