Title
(EN) METHOD AND SYSTEM FOR DETERMINING ROAD DATA
(FR) PROCÉDÉ ET SYSTÈME DE DÉTERMINATION DE DONNÉES DE ROUTE
Abstract
(EN)
Disclosed is a method, a system and a computer program determining a road data comprising the steps of: (i) measuring variables suitable for determining an actual trajectory (A) of the vehicle; (ii) determining the actual trajectory (A) from the measured variables; (iii) estimating road geometry values based on the determined actual trajectory (A); and (iv) determining a virtual road (VR) the vehicle is following based on the estimated road geometry data and the actual trajectory (A).
(FR)
La présente invention se rapporte à un procédé, à un système et à un programme d'ordinateur déterminant des données de route comprenant les étapes consistant à : (i) mesurer des variables appropriées pour déterminer une trajectoire réelle (A) du véhicule; (ii) déterminer la trajectoire réelle (A) à partir des variables mesurées; (iii) évaluer des valeurs de géométrie de route sur la base de la trajectoire réelle déterminée (A); et (iv) déterminer une route virtuelle (VR) que suit le véhicule sur la base des données de géométrie de route évaluées et de la trajectoire réelle (A).
