Title (EN) AUTOMATIC TROLLEY GUIDANCE
(FR) GUIDAGE DE CHARIOT DE LIGNE ÉLECTRIQUE AUTOMATIQUE
Abstract:
(EN) A system and method for guiding an off-highway truck along a roadway with respect to a trolley line determine a position of the off-highway truck on the roadway by sensing two or more roadside objects and uses the determined position of the off-highway truck and a known position of the trolley line relative to the two or more roadside objects to automatically determine a relative position of the off-highway truck under the trolley line. Based on the relative position of the off-highway truck under the trolley line, the off-highway truck is automatically steered to alter the position of the off-highway truck relative to the trolley line, e.g., to maintain an electrical power flow from the trolley line to the off-highway truck.
(FR) L'invention porte sur un système et sur un procédé pour guider un camion hors autoroute le long d'une chaussée vis-à-vis d'une ligne de chariot de ligne électrique, lesquels déterminent une position du camion hors autoroute sur la chaussée par détection d'au moins deux objets de bord de route, et lesquels utilisent la position déterminée du camion hors autoroute et une position connue de la ligne de chariot de ligne électrique par rapport aux au moins deux objets de bord de route afin de déterminer automatiquement une position relative du camion hors autoroute sous la ligne de chariot de ligne électrique. Sur la base de la position relative du camion hors autoroute sous la ligne de chariot de ligne électrique, le camion hors autoroute est automatiquement dirigé de façon à altérer la position du camion hors autoroute par rapport à la ligne de chariot de ligne électrique, par exemple de façon à maintenir un débit d'énergie électrique de la ligne de chariot électrique au camion hors autoroute.
