Patent number: 10836351Abstract: A method for authorizing the use of a motor vehicle by a portable identification transmitter is provided. According to the method, a first vehicle antenna emits a first signal, which is received by an identification-transmitter antenna. The identification transmitter determines at least one of the spatial components of the first electromagnetic field of the received first signal. A second vehicle antenna emits a second signal, which is received by the identification-transmitter antenna. The identification transmitter determines at least one of the spatial components of the second electromagnetic field of the received second signal. A computer determines the angle between the determined spatial component of the first electromagnetic field and the determined spatial component of the second electromagnetic field. 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.Type: GrantFiled: June 15, 2018Date of Patent: November 17, 2020Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Helmut Wagatha, Stefan Heinbockel, Fredrik Hocke, Ralf Wistorf

Patent number: 10703334Abstract: 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.Type: GrantFiled: June 15, 2018Date of Patent: July 7, 2020Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Helmut Wagatha, Stefan Heinbockel, Ralf Wistorf, Fredrik Hocke

Patent number: 10640085Abstract: A method for authorizing the use of a motor vehicle by a portable identification transmitter is provided. According to the method, a first vehicle antenna emits a first signal and a second vehicle antenna emits a second signal. An identification transmitter determines at least one of the spatial components of first and second electromagnetic fields, respectively, of the first and second signals.
