Abstract
A method includes: a) triggering, at an instant tuj, an exchange of radio signals between a mobile transceiver fixed to the vehicle and a fixed transceiver; then b) computing a rough distance only from the transmission or reception instants of the exchanged radio signals; (c) constructing an estimated position of the vehicle at an instant t; (d) correcting the computed rough distance, then using this corrected rough distance to correct the estimated position. This correction comprises: computing an apparent velocity movement vof the vehicle towards the fixed transceiver; then adding a corrective term δdto the computed rough distance, which corrective term is computed from the following relation: δd=v·DT0, where DT0 is equal to the elapsed time between the instants tuand t.
