Patent ID: 7590489

Claim:
Method for guiding in real time a landborne vehicle provided with an on-board navigation system, wherein the navigation and guiding data is processed in a remote manner in a navigation and guiding server external to the vehicle, from an on-board positioning module in this vehicle and communicating information regarding the position of the vehicle to said server, wherein said method consists in at least: a) transmitting from said positioning module to said server position coordinates of the vehicle at a first given moment; b) calculating, in said server external to the vehicle, the initial latency time and the return latency time, respectively, between said vehicle and said server; c) estimating, from current mapping information corresponding to the current geographical position of said vehicle and from an estimation of the average speed of said vehicle over at least part of an itinerary of said vehicle located relative to this current mapping information, the distance covered by the vehicle during the initial latency time and the return latency time, respectively; d) correcting said position coordinates of the vehicle at the first given moment by the value of the distances covered during the initial latency time and the return latency time, respectively, in order to generate corrected position coordinates; e) triggering the transmission of a guidance command from said server to the vehicle if said corrected coordinates correspond to a positioning of the vehicle allowing an appropriate reaction of the user of the vehicle in accordance with the guidance command.
