Title (EN) SYSTEM AND METHOD FOR DETERMINING VEHICLE POSITION BASED UPON LIGHT-BASED COMMUNICATION USING SIGNAL-TO-NOISE RATIO OR RECEIVED SIGNAL STRENGTH INDICATOR
(FR) SYSTÈME ET PROCÉDÉ DE DÉTERMINATION DE LA POSITION D'UN VÉHICULE EN FONCTION D'UNE COMMUNICATION FONDÉE SUR LA LUMIÈRE À L'AIDE D'UN RAPPORT SIGNAL SUR BRUIT OU D'UN INDICATEUR D'INTENSITÉ DE SIGNAL REÇU
Abstract:
(EN) A system and method for determining vehicle position uses light based communication (LBC) signals and a received signal strength indicator (RSSI) to determine the vehicle position. Each vehicle includes a LBC system having an array of transmitting light emitting diodes (LEDs) and an array of receiver photodiodes for transmitting and receiving pulsed light binary messages. Each LBC system has a controller coupled to the transmitter diodes and receiver diodes. The controller includes a vehicle communication module that may be executed by a processor to determine the distance. The processor models a first distance between a first transmitting LBC system and a first receiving LBC system, then models a second distance between a second transmitting LBC system and the first receiving LBC system, and then determines the distance between the first vehicle and the second vehicle using trilateration of the first distance and the second distance.
(FR) L'invention concerne un système et un procédé permettant de déterminer la position d'un véhicule utilisant des signaux de communication fondée sur la lumière (LBC) et un indicateur d'intensité de signal reçu (RSSI) afin de déterminer la position du véhicule. Chaque véhicule comprend un système LBC possédant un réseau de diodes électroluminescentes (DEL) émettrices et un réseau de photodiodes réceptrices afin de transmettre et de recevoir des messages binaires lumineux pulsés. Chaque système LBC comprend un dispositif de commande relié aux diodes émettrices et aux diodes réceptrices. Le dispositif de commande comprend un module de communication de véhicule pouvant être exécuté par un processeur afin de déterminer la distance. Le processeur modélise une première distance entre un premier système LBC émetteur et un premier système LBC récepteur, puis modélise une seconde distance entre un second système LBC émetteur et le premier système LBC récepteur, puis détermine la distance entre le premier véhicule et le second véhicule à l'aide d'une trilatération de la première distance et de la seconde distance.
