Abstract:
A method for authorizing the use of a motor vehicle, in particular a two-wheeled or four-wheeled motor vehicle, which has a first and a second antenna where the first antenna and the second antenna are spaced apart from each other, by a portable identification device which has an identification transmitter antenna. In order to increase the manipulation security of a known method, it is determined whether the identification device is moving toward the motor vehicle. This can on the one hand be determined in that the identification device repeatedly identifies the field strength of the signals emitted by the motor vehicle and identifies whether the field strength or field strengths is or are increasing. This can on the other hand be determined in that the identification device repeatedly determines the angle between the signals emitted by the motor vehicle and examines whether the repeatedly determined angles are increasing.

Claim (Index 1):
A method for authorizing use of a motor vehicle, wherein the motor vehicle has a first antenna and a second antenna, wherein the first antenna and the second antenna are at a physical distance from one another, comprising the acts of:\n a) emitting a first signal by the first antenna that is received by an identification transmitter antenna of a portable identification transmitter; b) ascertaining by the portable identification transmitter a spatial component of a first electromagnetic field of the received first signal; c) emitting a second signal by the second antenna that is received by the identification transmitter antenna; d) ascertaining by the portable identification transmitter a spatial component of a second electromagnetic field of the received second signal; e) repeatedly ascertaining by the portable identification transmitter, after a predetermined time interval has elapsed, an angle between the ascertained spatial component of the first electromagnetic field of the received first signal and the ascertained spatial component of the second electromagnetic field of the received second signal; f) repeatedly ascertaining by the portable identification transmitter, after the predetermined time interval has elapsed, a field strength of the first electromagnetic field of the received first signal and a field strength of the second electromagnetic field of the received second signal; and g) sending an authorization signal to authorize the use of the motor vehicle to the motor vehicle by the portable identification transmitter only if:\n the angle exceeds a predetermined threshold value; \n the angle increases; \n the field strength of the first electromagnetic field increases; and/or \n the field strength of the second electromagnetic field increases.
