The identification transmitter transmits an authorization signal for authorizing use of the motor vehicle to the motor vehicle only if the angle exceeds a predetermined threshold value.

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.
