Title
(EN) METHOD FOR CONTROLLING A MOTOR VEHICLE EQUIPPED WITH AUTONOMOUS DRIVING MEANS
(FR) PROCÉDÉ DE COMMANDE D'UN VÉHICULE AUTOMOBILE MUNI DE MOYENS DE CONDUITE AUTONOME
Abstract
(EN) Method for controlling a motor vehicle equipped with autonomous driving means, with sensors comprising at least one telemetry sensor, with fusion means for fusing data from the sensors and with a road navigation assistance means with traffic management, the fusion means being configured so as to determine an estimated trajectory of the motor vehicle, the position and the speed of at least one target object detected by the sensors around the motor vehicle, the markings of at least one traffic lane and the closest target object, the method comprising the following steps: - determining a first value if the estimated trajectory of the vehicle intersects or approaches the central line of at least one detected traffic lane, - determining a second value if the closest target object on the driving line of the motor vehicle is also detected by the at least one telemetry sensor, - determining a third value if a collision will occur by comparing the distance between the closest target object and the motor vehicle to a predetermined threshold, - determining a fourth value if the space between the motor vehicle and the closest target object is empty on the basis of the data from the at least one telemetry sensor, and - determining a fifth value if there is congestion on the trajectory of the vehicle, and then - determining whether the autonomous driving means are able to be activated on the basis only of the first to fifth values.
(FR) Procédé de commande d'un véhicule automobile muni de moyens de conduite autonome, de capteurs comprenant au moins un capteur de télémétrie, de moyens de fusion des données des capteurs et d'un moyen d'aide à la navigation routière avec gestion du trafic, les moyens de fusion étant configurés pour déterminer une trajectoire estimée du véhicule automobile, la position et la vitesse d'au moins un objet cible détecté par les capteurs autour du véhicule automobile, les marquages d'au moins une voie de circulation ainsi que l'objet cible le plus proche, le procédé comprenant les étapes suivantes : - on détermine une première valeur s'il existe un croisement ou un rapprochement entre la trajectoire estimée du véhicule et la ligne centrale d'au moins une voie de circulation détectée, - on détermine une deuxième valeur si l'objet cible le plus proche dans la ligne de circulation du véhicule automobile est également détectée par le au moins un capteur de télémétrie, - on détermine une troisième valeur si une collision va intervenir en comparant la distance entre l'objet cible le plus proche et le véhicule automobile à un seuil prédéterminé, - on détermine une quatrième valeur si l'espace entre le véhicule automobile et l'objet cible le plus proche est vide en fonction des données du au moins un capteur de télémétrie, et - on détermine une cinquième si un embouteillage est présent sur la trajectoire du véhicule, puis - on détermine si les moyens de conduite autonome peuvent être activés en fonction uniquement de la première à la cinquième valeurs.
