Method for authorizing the use of a motor vehicle, in particular a two- or four-wheeled motor vehicle, that has at least one first and one second antenna, wherein the first antenna and the second antenna are at a physical distance from one another, by means of a portable identification transmitter that has an identification transmitter antenna, having the following steps: - the first motor vehicle antenna emits a first signal that is received by the identification transmitter antenna, - the identification transmitter detects at least one of the spatial components of the first electromagnetic field of the received first signal, in particular using an angle-resolving magnetic field sensor, - the second motor vehicle antenna emits a second signal that is received by the identification transmitter antenna, - the identification transmitter detects at least one of the spatial components of the second electromagnetic field of the received second signal, in particular using an angle-resolving magnetic field sensor, - a first computer, in particular a computer in the identification transmitter, repeatedly detects, after a predetermined first time interval has elapsed, the angle at least between the detected spatial component of the first electromagnetic field of the received first signal and the detected spatial component of the second electromagnetic field of the received second signal, - the identification transmitter repeatedly detects, after a predetermined time interval, in particular the predetermined first time interval, has elapsed, the field strength of at least the first electromagnetic field of the received first signal and, in particular repeatedly, also the field strength of the second electromagnetic field of the received second signal, wherein the detection of the field strengths is in particular performed using the first computer, - the identification transmitter sends an authorization signal for authorizing the use of the motor vehicle to the motor vehicle only if the following prerequisites are cumulatively met: - the angle repeatedly detected each time after the predetermined first time interval has elapsed exceeds a predetermined threshold value, - the repeatedly detected angle increases or becomes greater, and/or - the repeatedly measured field strength of the first and/or second electromagnetic field likewise increases or becomes greater. - the first motor vehicle antenna emits a first signal that is received by the identification transmitter antenna, - the identification transmitter detects at least one of the spatial components of the first electromagnetic field of the received first signal, in particular using an angle-resolving magnetic field sensor, - the second motor vehicle antenna emits a second signal that is received by the identification transmitter antenna, - the identification transmitter detects at least one of the spatial components of the second electromagnetic field of the received second signal, in particular using an angle-resolving magnetic field sensor, - a first computer, in particular a computer in the identification transmitter, repeatedly detects, after a predetermined first time interval has elapsed, the angle at least between the detected spatial component of the first electromagnetic field of the received first signal and the detected spatial component of the second electromagnetic field of the received second signal, - the identification transmitter repeatedly detects, after a predetermined time interval, in particular the predetermined first time interval, has elapsed, the field strength of at least the first electromagnetic field of the received first signal and, in particular repeatedly, also the field strength of the second electromagnetic field of the received second signal, wherein the detection of the field strengths is in particular performed using the first computer, - the identification transmitter sends an authorization signal for authorizing the use of the motor vehicle to the motor vehicle only if the following prerequisites are cumulatively met: - the angle repeatedly detected each time after the predetermined first time interval has elapsed exceeds a predetermined threshold value, - the repeatedly detected angle increases or becomes greater, and/or - the repeatedly measured field strength of the first and/or second electromagnetic field likewise increases or becomes greater.
