Abstract:
A method for authorizing the use of a motor vehicle, including a first antenna and a second antenna, wherein the first antenna and the second antenna are spaced apart from each other in space, by a portable identification device that has an identification device antenna. According to the method, it is determined whether the identification device is moving toward the motor vehicle, which can be determined by the identification device repeatedly identifying the field strength of the signals emitted by the motor vehicle and examining whether the field strength is increasing. Alternatively, the identification device can repeatedly identify the angle between the signals emitted by the motor vehicle and examine whether the repeatedly identified angles are increasing.

Claim (Index 1):
A method for authorizing use of a motor vehicle, including a first antenna and a second antenna, wherein the first antenna and the second antenna are physically separated from each other in space, by a portable identification encoder that has an identification encoder antenna, the method comprising:\n emitting, by the first antenna, a first signal, which is received by the identification encoder antenna; determining, by the identification encoder, at least one of spatial components of a first electromagnetic field of the first signal, using an angular resolution magnetic field sensor; emitting, by the second antenna, a second signal, which is received by the identification encoder antenna; determining, by the identification encoder, at least one of spatial components of a second electromagnetic field of the second signal, using the angular resolution magnetic field sensor; repeatedly transmitting, by the identification encoder, the at least one determined spatial component of the first electromagnetic field of the first signal, in each case after expiration of a predetermined time interval, and repeatedly transmitting the at least one determined spatial component of the second electromagnetic field of the second signal, in each case after the expiration of the predetermined time interval, to the motor vehicle, repeatedly determining after the expiration of the predetermined time interval, by a computer disposed in the motor vehicle, an angle between the determined spatial component of the first electromagnetic field of the first signal and the determined spatial component of the second electromagnetic field of the second signal; and supplying, by the motor vehicle, an authorization signal to authorize the use of the motor vehicle only when the angle, which is determined repeatedly after the expiration of the predetermined time interval, exceeds a predefined threshold, and at least one of the repeatedly determined angle increases and a repeatedly measured field strength of at least one of the first electromagnetic field and the second electromagnetic field increases.
