Title
(EN) VEHICLE CONTROL SYSTEM
(FR) SYSTEME DE COMMANDE DE VEHICULE
Abstract
(EN) This vehicle control system is equipped with an autonomous travel vehicle that travels autonomously in a mine, a manned vehicle, and an autonomous travel vehicle. The autonomous travel vehicles and the manned vehicle are each equipped with a local position estimation device and an onboard communication terminal, and are communicably connected via one wireless channel. The manned vehicle uses a first communication method to transmit manned vehicle position information with a first granularity, and when the autonomous travel vehicle determines, on the basis of the manned vehicle position information transmitted by the first communication method, that the distance to the manned vehicle is equal to or less than a first vehicle-to-vehicle distance threshold value, the autonomous travel vehicle instructs the manned vehicle to transmit the manned vehicle position information by a second communication method different from the first communication method and with a second granularity smaller than the first granularity.
(FR) L'invention concerne un système de commande de véhicule qui est équipé d'un véhicule à déplacement autonome qui se déplace de manière autonome dans une mine, un véhicule à conducteur et un véhicule à déplacement autonome. Les véhicules à déplacement autonomes et le véhicule à conducteur sont chacun équipés d'un dispositif d'estimation de position locale et d'un terminal de communication embarqué, et sont connectés en communication par le biais d'un canal sans fil. Le véhicule à conducteur utilise un premier procédé de communication pour transmettre des informations de position de véhicule à conducteur avec une première granularité, et lorsque le véhicule à déplacement autonome détermine, sur la base des informations de position de véhicule à conducteur transmises par le premier procédé de communication, que la distance par rapport au véhicule à conducteur est inférieure ou égale à une première valeur de seuil de distance entre véhicules, le véhicule à déplacement autonome ordonne au véhicule à conducteur de transmettre les informations de position de véhicule à conducteur par un deuxième procédé de communication différent du premier procédé de communication et avec une deuxième granularité plus petite que la première granularité.
