Method for updating a road map from a network of contributors

摘要

The invention relates to a method for updating a road map from a plurality of so-called “contributor” vehicles, connected to at least one data processing server by a communication network, each contributing vehicle comprising a module. geolocation, a calculator and a communication module. The method comprises in particular the steps of calculating, by the at least one data processing server of a first weighting coefficient of a track of the vehicle as a function of the number of satellites used to generate said track, of a second coefficient weighting of the trace received as a function of at least one reference trace stored in the at least one data processing server, and of a third weighting coefficient of the trace received by applying a mathematical function to the first calculated weighting coefficient and the second calculated weighting coefficient, for weighting the received trace with the third calculated weighting coefficient, for updating the at least one reference trace corresponding to the section of the vehicle route from the weighted track and update of a road map from the updated reference track.
