Title
(EN) SYSTEM AND METHOD FOR OPTIMIZING AUTONOMOUS VEHICLE CAPABILITIES IN ROUTE PLANNING
(FR) SYSTÈME ET PROCÉDÉ PERMETTANT D'OPTIMISER DES CAPACITÉS DE VÉHICULE AUTONOME LORS D'UNE PLANIFICATION D'ITINÉRAIRE
Abstract
(EN) Systems and methods described herein determine an optimal lane trajectory and route for an autonomous vehicle under changing road conditions and forecast autonomous car performance along a route. A road's profile is analyzed to determine a safe lateral lane position. In ice or snow, a vehicle may follow ruts made by previous vehicles, even if following such ruts does not place a vehicle in a lane's center. In warmer weather, a vehicle may drive outside the ruts to avoid risks of aquaplaning. Dynamic road conditions and AV support along a route are used to maximize AV use and to forecast AV performance. A vehicle control system calculates sensor limitations and uses these sensor limitations when calculating which route to select.
(FR) La présente invention concerne des systèmes et des procédés qui déterminent un itinéraire et une trajectoire de voie optimaux pour un véhicule autonome dans des conditions de route variables et permettent de prévoir des performances de véhicule autonome le long d'un itinéraire. Un profil de route est analysé pour déterminer une position de voie latérale sans risques. En cas de gel ou de neige, un véhicule peut suivre des ornières réalisées par les véhicules précédents, même si le fait de suivre de telles ornières ne place pas un véhicule au centre de la voie. Dans des conditions météorologiques plus chaudes, un véhicule peut se déplacer à l'extérieur des ornières pour éviter les risques d'aquaplanage. Des conditions de route dynamiques et un support de véhicule autonome (AV pour Autonomous Vehicle) le long d'un itinéraire sont utilisés pour maximiser une utilisation de véhicule autonome et pour prévoir les performances du véhicule autonome. Un système de commande de véhicule calcule des limitations de capteur et utilise ces limitations de capteur lors du calcul de la route à sélectionner.
