Title
(EN) METHOD AND SYSTEM TO CONSTRUCT SURROUNDING ENVIRONMENT FOR AUTONOMOUS VEHICLES TO MAKE DRIVING DECISIONS
(FR) PROCÉDÉ ET SYSTÈME PERMETTANT DE CONSTRUIRE UN ENVIRONNEMENT DESTINÉ À DES VÉHICULES AUTONOMES AFIN DE PRENDRE DES DÉCISIONS DE CONDUITE
Abstract
(EN) In response to sensor data received from sensors mounted on an autonomous vehicle, a surrounding environment is perceived based on the sensor data. The surrounding environment includes multiple sub-environments. For each of the sub-environments, one of a plurality of driving scenario handlers associated with the sub-environment is identified, each driving scenario handler corresponding to one of a plurality of driving scenarios. The identified driving scenario handler is invoked to determine an individual driving condition within the corresponding sub-environment. An overall driving condition for the surrounding environment is determined based on the individual driving conditions provided by the identified driving scenario handlers. A route segment is planned based on the overall driving condition of the surrounding environment, the route segment being one of a plurality of route segments associated with a route. The autonomous vehicle is controlled and driven based on the planned route segment.
(FR) Selon la présente invention, en réponse à des données de capteur reçues en provenance de capteurs montés sur un véhicule autonome, un environnement est perçu sur la base des données de capteur. L'environnement comprend de multiples sous-environnements. Pour chacun des sous-environnements, un élément d'une pluralité de gestionnaires de scénario de conduite associés au sous-environnement est identifié, chaque gestionnaire de scénario de conduite correspondant à un élément d'une pluralité de scénarios de conduite. Le gestionnaire de scénario de conduite identifié est appelé pour déterminer un état de conduite individuel dans le sous-environnement correspondant. Un état de conduite global destiné à l'environnement est déterminé sur la base des états de conduite individuels fournis par les gestionnaires de scénario de conduite identifiés. Un segment d'itinéraire est planifié sur la base de l'état de conduite global de l'environnement, le segment d'itinéraire étant un élément d'une pluralité de segments d'itinéraire associés à un itinéraire. Le véhicule autonome est commandé et conduit sur la base du segment d'itinéraire planifié.
