Abstract[English]
A method of sensing occupancy of a vehicle using ultra-wide band (UWB) communication includes transmitting and receiving a UWB signal within the vehicle, obtaining channel impulse response (CIR) data corresponding to the UWB signal as received within the vehicle, calculating power delay profile (PDP) results for the CIR data, determining, based on the calculated PDP results, the occupancy of the vehicle, and at least one of generating, storing, and transmitting occupancy sensing results based on the determined occupancy of the vehicle. The occupancy sensing results include data that indicates at least one of a presence of occupants within the vehicle, a number of occupants within the vehicle, and locations of occupants within the vehicle.[French]
Un procédé de détection d'occupation d'un véhicule à l'aide d'une communication à ultra large bande (UWB) comprend la transmission et la réception d'un signal UWB à l'intérieur du véhicule, l'obtention de données de réponse impulsionnelle de canal (CIR) correspondant au signal UWB tel que reçu à l'intérieur du véhicule, le calcul de résultats de profil de retard de puissance (PDP) pour les données CIR, la détermination, sur la base des résultats PDP calculés, de l'occupation du véhicule, et la génération, le stockage et/ou la transmission de résultats de détection d'occupation sur la base de l'occupation déterminée du véhicule. Les résultats de détection d'occupation comprennent des données qui indiquent une présence d'occupants à l'intérieur du véhicule et/ou un certain nombre d'occupants à l'intérieur du véhicule et/ou des emplacements d'occupants à l'intérieur du véhicule.
