Title (EN) GUIDEWAY MOUNTED VEHICLE LOCALIZATION AND ALIGNMENT SYSTEM AND METHOD
(FR) SYSTÈME ET PROCÉDÉ DE LOCALISATION ET D'ALIGNEMENT DE VÉHICULE MONTÉ SUR UNE VOIE DE GUIDAGE
Abstract:
(EN) A system comprises a first sensor on a first end of a vehicle and an on- board controller coupled to the first sensor. The first sensor is configured to detect a radio frequency (RF) signature of a marker along a guideway. The first sensor is a radar detection device. The on-board controller is configured to determine a first position of the vehicle on the guideway or a first distance from the position of the vehicle to a stopping location along the guideway based on at least the RF signature received from the first sensor. The marker is a metasurface plate comprising a first diffused element, a first retroreflector element, a first absorbing element and a second diffused element between the first retroreflector element and the first absorbing element.
(FR) L'invention concerne un système comprenant un premier capteur sur une première extrémité d'un véhicule, et un contrôleur embarqué couplé au premier capteur. Le premier capteur est configuré pour détecter une signature radiofréquence (RF) d'un marqueur le long d'une voie de guidage. Le premier capteur est un dispositif de détection radar. Le contrôleur embarqué est configuré pour déterminer une première position du véhicule sur la voie de guidage, ou une première distance de la position du véhicule par rapport à une position d'arrêt le long de la voie de guidage sur la base, au moins en partie, de la signature RF reçue du premier capteur. Le marqueur est une plaque de métasurface comprenant un premier élément diffusé, un premier élément rétroréflecteur, un premier élément absorbant, et un second élément diffusé entre le premier élément rétroréflecteur et le premier élément absorbant.
