  • Method and apparatus for determining a propagation delay and/or a distance between multiple transceivers, particularly for a vehicle-entry and/or starting system
    Patent number: 11343076
    Abstract: A method and apparatus for determining a propagation delay and/or a distance between a plurality of transceivers, in particular between transceivers outside and/or as part of a motor vehicle, wherein the transceivers are each designed: to generate identical codes in a plurality of these transceivers, using a calculation method known to them, from at least one starting value transmitted, in particular, from one of the transceivers to the further transceivers, to transmit one or more messages from at least one of the transceivers to one or more further ones of the transceivers, which messages each contain at least one of the codes, to determine at least one propagation delay and/or at least one distance between at least two of the transceivers, in particular from the propagation delay and/or transmission times of the one or more messages.
