A method for estimating a position of a vehicle () relative to one or more radio transceivers (). The method including the steps of; obtaining propagation delay data associated with radio transmission between a vehicle transceiver () included in the vehicle () and the one or more radio transceivers (); obtaining vehicle motion data related to a trajectory of the vehicle (); identifying one or more multipath components, MPC, in the propagation delay data, the MPC relates to a radio transmission propagation path between a fixed radio transceiver () and the vehicle transceiver (); determining an MPC track for each identified MPC based on the vehicle motion data and on the propagation delay data, MPC track representing evolution of an MPC over time; and estimating the position of the vehicle () relative to the one or more radio transceivers () based on the MPC tracks.

Vehicle positioning based on wireless signal transmission

A method for vehicular self-positioning is executed by a positioning device in a vehicle. The positioning device computes a current estimated position of the vehicle as a function of local motion data obtained from a motion sensor in the vehicle, and operates an RF module in the vehicle to receive a reference signal from one or more base stations in an environment of the vehicle, the respective base station being configured for telecommunication and being part of a 3GPP infrastructure. The positioning device further processes the reference signal to determine measured values of at least one path parameter for a selected set of multipath components, and operates a positioning algorithm, e.g. SLAM, on at least the current estimated position and the measured values to calculate a current output position of the vehicle and position information for an origin of each of the multipath components.
