Abstract

Utilisation de système UWB de véhicule On propose un procédé d’utilisation d’un système UWB de véhicule comprenant un ou plusieurs capteurs UWB et ayant enregistré un ou plusieurs identifiants. Le procédé comprend périodiquement une ou plusieurs localisations. Les une ou plusieurs localisations incluent, pour chaque identifiant respectif, au moins une localisation respective de l’identifiant respectif avec les un ou plusieurs capteurs UWB. Les une ou plusieurs localisations sont temporellement séparées. Le procédé comprend périodiquement une pluralité de mesures radar. La pluralité de mesures radar inclut, pour au moins un capteur UWB respectif, plusieurs mesures radar respectives. Le nombre de mesures radar respectives est, pour chaque identifiant, supérieur au nombre d’au moins une localisation respective de l’identifiant avec les un ou plusieurs capteurs UWB. Le procédé améliore l’utilisation du système UWB de véhicule. [Fig. 3]
