VEHICLE POSITIONING BASED ON WIRELESS SIGNAL TRANSMISSION

摘要

A method for estimating a position of a vehicle (100) relative to one or more radio transceivers (150), the method comprising; obtaining propagation delay data associated with radio transmission between a vehicle transceiver (110) comprised in the vehicle (100) and the one or more radio transceivers (150); obtaining vehicle motion data related to a trajectory of the vehicle (100); identifying one or more multipath components, MFC, in the propagation delay data, wherein an MFC relates to a radio transmission propagation path between a fixed radio transceiver (150) and the vehicle transceiver (110); determining an MFC track for each identified MFC based on the vehicle motion data and on the propagation delay data, wherein an MFC track represents evolution of an MFC over time; and estimating the position of the vehicle (100) relative to the one or more radio transceivers (150) based on the MFC tracks.
