Title
(EN) SYSTEMS AND METHODS FOR OPTIMIZING TRAJECTORY PLANNER BASED ON HUMAN DRIVING BEHAVIORS
(FR) SYSTÈMES ET PROCÉDÉS POUR OPTIMISER UN PLANIFICATEUR DE TRAJECTOIRE SUR LA BASE DE COMPORTEMENTS DE CONDUITE HUMAINS
Abstract
(EN) In one embodiment, a computing system of a vehicle may receive vehicle driving data associated with a vehicle driving in an environment and detected environment data associated with the environment. The system may generate a reference trajectory of the vehicle driving in the environment based on the vehicle driving data. The system may determine driving constraints associated with the environment based on the detected environmental data. The system may generate a trajectory of the vehicle based on the driving constraints. The system may determine a difference in at least one parameter associated with the trajectory relative to at least one corresponding parameter associated with the reference trajectory. The system may adjust weight values associated with cost functions of the trajectory based on the difference between the at least one parameter associated with the trajectory and the corresponding parameter associated with the reference trajectory.
(FR) Dans un mode de réalisation de l'invention, un système informatique d'un véhicule peut recevoir des données de conduite de véhicule associées à un véhicule circulant dans un environnement et des données d'environnement détectées associées à l'environnement. Le système peut générer une trajectoire de référence du véhicule circulant dans l'environnement sur la base des données de conduite de véhicule. Le système peut déterminer des contraintes de conduite associées à l'environnement sur la base des données environnementales détectées. Le système peut générer une trajectoire du véhicule sur la base des contraintes de conduite. Le système peut déterminer une différence dans au moins un paramètre associé à la trajectoire par rapport à au moins un paramètre correspondant associé à la trajectoire de référence. Le système peut ajuster des valeurs de poids associées à des fonctions de coût de la trajectoire sur la base de la différence entre le ou les paramètres associés à la trajectoire et le paramètre correspondant associé à la trajectoire de référence.
