Title
(EN) INDEPENDENT TRAJECTORY VALIDATION SYSTEM FOR VEHICLES
(FR) SYSTÈME DE VALIDATION DE TRAJECTOIRE INDÉPENDANT POUR VÉHICULES
Abstract
(EN) A method includes receiving, by a computing system of a vehicle, a planned trajectory for the vehicle based on first sensor data associated with an external environment. The planned trajectory is generated by a primary computing system associated with a first sensor. The method further includes determining an environmental condition associated with the external environment. The environmental condition is included in second sensor data generated by a second sensor. The method further includes analyzing one or more parameters associated with the planned trajectory to determine whether the planned trajectory is based on the environmental condition, and, in response to determining that the primary computing system fails to base the planned trajectory upon the environmental condition, altering the one or more parameters associated with the planned trajectory to generate an altered planned trajectory. The method thus includes instructing the vehicle to execute the altered planned trajectory.
(FR) L'invention concerne un procédé comprenant la réception, par un système informatique d'un véhicule, d'une trajectoire planifiée pour le véhicule basée sur des premières données de capteur associées à un environnement externe. La trajectoire planifiée est générée par un système informatique primaire associé à un premier capteur. Le procédé comprend en outre la détermination d'une condition environnementale associée à l'environnement externe. La condition environnementale est incluse dans des secondes données de capteur générées par un second capteur. Le procédé comprend en outre l'analyse d'un ou plusieurs paramètres associés à la trajectoire planifiée pour déterminer si la trajectoire planifiée est basée sur la condition environnementale et, en réponse à la détermination du fait que le système informatique primaire ne parvient pas à baser la trajectoire planifiée sur la condition environnementale, modifier le ou les paramètres associés à la trajectoire planifiée pour générer une trajectoire planifiée modifiée. Le procédé comprend ainsi l'instruction au véhicule d'exécuter la trajectoire planifiée modifiée.
