Title
(EN) A SYSTEM FOR GRID-BASED MERGE CUT-IN PREDICTION AND METHOD THEREOF
(FR) SYSTÈME DE PRÉDICTION D'AMORÇAGE DE CONVERGENCE REPOSANT SUR UN QUADRILLAGE ET SON PROCÉDÉ
Abstract
(EN) A prediction system implemented in a host vehicle to predict a merge cut-in for an autonomous vehicle. The system comprises an input unit for capturing neighbouring information of the host vehicle, and a processing unit to receive the captured neighbouring information and generate a grid map by determining shape and dimensions of a grid, estimate trajectory of each target vehicle of the one or more target vehicles, based on driver behaviour model of each target vehicle, to determine optimized path of each target vehicle, and generate a global manoeuvre model by analysing motion of each neighbouring target vehicle, wherein on generation of the global manoeuvre model a merge cut-in threat for the host vehicle is computed by performing centralized risk management and utilizing the predicted trajectory of the one or more target vehicles.
(FR) L'invention concerne un système de prédiction implémenté dans un véhicule hôte permettant de prédire un amorçage de convergence pour un véhicule autonome. Le système comprend une unité d'entrée destinée à capturer des informations de voisinage du véhicule hôte, et une unité de traitement destinée à recevoir les informations de voisinage capturées et à générer une carte à quadrillage en déterminant la forme et les dimensions d'un quadrillage, à estimer la trajectoire de chaque véhicule cible du ou des véhicules cibles, sur la base d'un modèle de comportement de conducteur de chaque véhicule cible, pour déterminer un trajet optimisé de chaque véhicule cible, et à générer un modèle de manœuvre global par analyse de déplacement de chaque véhicule cible de voisinage, lors de la génération du modèle de manœuvre global, une menace d'amorçage de convergence pour le véhicule hôte étant calculée par une mise en œuvre d'une gestion de risque centralisée et par une utilisation de la trajectoire prédite du ou des véhicules cibles.
