Method for authorizing the use of a motor vehicle, in particular a two-wheeled or four-wheeled motor vehicle, which has at least one first and one second antenna, wherein the first antenna and the second antenna are physically separated from each other, by means of a portable identification encoder that has an identification encoder antenna, having the following steps: - the first motor vehicle antenna emits a first signal, which is received by the identification encoder antenna, - the identification encoder detects at least one of the spatial components of the first electromagnetic field of the received first signal, in particular using an angular resolution magnetic field sensor, - the second motor vehicle antenna emits a second signal, which is received by the identification encoder antenna, - the identification encoder detects at least one of the spatial components of the second electromagnetic field of the received second signal, in particular using an angular resolution magnetic field sensor, - the identification encoder repeatedly transmits the detected at least one spatial component of the first electromagnetic field of the received first signal, in each case after the expiration of a predetermined time interval, in particular of the first time interval, and repeatedly transmits the detected at least one spatial component of the second electromagnetic field of the received second signal, in each case after the expiration of a predetermined time interval, in particular of the first time interval, to the motor vehicle, - a first computer, in particular a computer in the motor vehicle, repeatedly detects after the expiration of a predetermined time interval, in particular after the expiration of a predetermined first or second time interval, 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 motor vehicle supplies an authorization signal for authorizing the use of the motor vehicle only when the following requirements are cumulatively met: - the angle, which is detected repeatedly after the expiration of the predetermined first time interval, exceeds a predetermined threshold value, - the repeatedly detected angle increases or becomes greater, and/or - the measured field strength of the first and/or second electromagnetic field also increases or becomes greater. - the first motor vehicle antenna emits a first signal, which is received by the identification encoder antenna, - the identification encoder detects at least one of the spatial components of the first electromagnetic field of the received first signal, in particular using an angular resolution magnetic field sensor, - the second motor vehicle antenna emits a second signal, which is received by the identification encoder antenna, - the identification encoder detects at least one of the spatial components of the second electromagnetic field of the received second signal, in particular using an angular resolution magnetic field sensor, - the identification encoder repeatedly transmits the detected at least one spatial component of the first electromagnetic field of the received first signal, in each case after the expiration of a predetermined time interval, in particular of the first time interval, and repeatedly transmits the detected at least one spatial component of the second electromagnetic field of the received second signal, in each case after the expiration of a predetermined time interval, in particular of the first time interval, to the motor vehicle, - a first computer, in particular a computer in the motor vehicle, repeatedly detects after the expiration of a predetermined time interval, in particular after the expiration of a predetermined first or second time interval, 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 motor vehicle supplies an authorization signal for authorizing the use of the motor vehicle only when the following requirements are cumulatively met: - the angle, which is detected repeatedly after the expiration of the predetermined first time interval, exceeds a predetermined threshold value, - the repeatedly detected angle increases or becomes greater, and/or - the measured field strength of the first and/or second electromagnetic field also increases or becomes greater.
