Abstract (en)
[origin: WO2014033247A1] Various embodiments relate to a method for determining a position (P) of an identification transmitter for an access control to a motor vehicle (1). The method comprises the emission of at least one electromagnetic field (80) by a respective transmitter (200a, 200b), an amplitude (81) of the at least one electromagnetic field (80) rotating in relation to the respective transmitter (200a, 200b). The method comprises measuring the at least one electromagnetic field (80) by means of the receiver (30), and determining a differential phase (91). The method further comprises determining the position (P) based on the at least one differential phase (91).
