Method for the control, by a supervising server, of the movement of a fleet of autonomously guided vehicles

A method of controlling, by a supervising server, movement of a fleet of autonomously guided vehicles in a movement area equipped with a plurality of wireless Wi-Fi access points, each of the guided vehicles comprising at least one geolocation device and a Wi-Fi communication module, the geolocation device comprising means for measuring movement of the vehicle relative to a plurality of physical reference elements in the movement area, the method comprising:

• recording coordinates of the access points in a database;
• causing at least one guided vehicle of the fleet to change the access point to which the guided vehicle is respectively communicatively coupled by disconnecting the Wi-Fi communication module of the at least one guided vehicle from an active access point and at least attempting to reconnect the Wi-Fi communication module of the at least one guided vehicle to a first nearest SSIDi access point for which the coordinates recorded in a database are the closest of the coordinates determined by the geolocation device;
• and
• causing the at least one guided vehicle to at least attempt to reconnect to a second nearest second SSIDi+1 access point:
• if an authentication delay of the communication module with the first nearest SSIDi access point exceeds a predetermined period Taut;
• and/or
• if a response period of the supervising server to a ping transmitted by the communication module with the first nearest SSIDi access point exceeds a predetermined period Tping;
• and
• safely stopping the at least one guided vehicle if a reconnection delay exceeds a period Tafety.
