Method for determining a corrected distance between a mobile transceiver fastened to a vehicle and a fixed transceiver, this method comprising the following steps when the vehicle is moving along a path segment belonging to a countable set of a plurality of predetermined path segments: a) acquisition , by an electronic computer, of transmission and reception times of radio signals exchanged between the fixed and mobile transceivers, b) computation , by the electronic computer, of a raw distance between the fixed and mobile transceivers solely from the acquired transmission and reception times of the exchanged radio signals, then c) determination , by the electronic computer, of the position of the vehicle, wherein the method comprises: - identification , among the set of predetermined path segments, of the predetermined segment on which the vehicle is currently found on the basis of the last position determined for this vehicle, then - selection of a correction function specifically associated with the identified segment using a table that associates, with each path segment, a respective correction function, each of these correction functions being able, when it is executed, to deliver a correction coefficient for correcting the raw distance, then - execution of the identified correction function to obtain a current correction coefficient, then - correction of the last raw distance computed using the current correction coefficient to obtain the corrected distance. a) acquisition , by an electronic computer, of transmission and reception times of radio signals exchanged between the fixed and mobile transceivers, b) computation , by the electronic computer, of a raw distance between the fixed and mobile transceivers solely from the acquired transmission and reception times of the exchanged radio signals, then c) determination , by the electronic computer, of the position of the vehicle, wherein the method comprises: - identification , among the set of predetermined path segments, of the predetermined segment on which the vehicle is currently found on the basis of the last position determined for this vehicle, then - selection of a correction function specifically associated with the identified segment using a table that associates, with each path segment, a respective correction function, each of these correction functions being able, when it is executed, to deliver a correction coefficient for correcting the raw distance, then - execution of the identified correction function to obtain a current correction coefficient, then - correction of the last raw distance computed using the current correction coefficient to obtain the corrected distance. - identification , among the set of predetermined path segments, of the predetermined segment on which the vehicle is currently found on the basis of the last position determined for this vehicle, then - selection of a correction function specifically associated with the identified segment using a table that associates, with each path segment, a respective correction function, each of these correction functions being able, when it is executed, to deliver a correction coefficient for correcting the raw distance, then - execution of the identified correction function to obtain a current correction coefficient, then - correction of the last raw distance computed using the current correction coefficient to obtain the corrected distance. <EOS>
