Zusammenfassung: | Disclosed is a method for generating a virtual lane for assisting autonomous driving, the method comprising the steps of: deriving a driving history by accumulating driving data of at least one surrounding vehicle measured by a composite sensor according to the passage of time; classifying the driving history into at least one driving section according to a driving pattern on the basis of self-attention implemented by a convolutional neural network (CNN); deriving a weighted driving history of the at least one surrounding vehicle by assigning a weight to the at least one driving section on the basis of the self-attention; determining a driving trajectory of the at least one surrounding vehicle by performing curve fitting on the weighted driving history through the CNN; and generating a virtual lane on an HD map for assisting autonomous driving on the basis of the driving trajectory.
La divulgation concerne un procédé de génération d'une voie virtuelle destinée à aider à la conduite autonome, le procédé comprenant les étapes consistant : à déduire un historique de conduite au moyen de l'accumulation de données de conduite d'au moins un véhicule environnant mesurées par un capteur composite en fonction du passage du temps ; à classer l'historique de conduite en au moins une section de conduite selon un motif de conduite sur la base d'une attention automatique mise en œuvre par un réseau neuronal convolutionnel (CNN) ; à déduire un historique de conduite pondéré dudit véhicule environnant au moyen de l'attribution d'une pondération à ladite section de conduite sur la base de l'attention automatique ; à déterminer une trajectoire de conduite dudit véhicule environnant au moyen de la réalisation d'un réglage de courbe sur l'historique de conduite pondéré par le biais du CNN ; et à générer une voie virtuelle sur une carte HD pour aider à la conduite autonome sur la base de la trajectoire de conduite.
