(EN) DEVICE FOR ACTIVE CONTROL OF SOUND INSULATION IN AN AUTONOMOUS VEHICLE PASSENGER COMPARTMENT
(FR) DISPOSITIF DE CONTRÔLE ACTIF DE L'ISOLATION PHONIQUE DANS L'HABITACLE D'UN VÉHICULE AUTONOME
Abstract
(EN)
A control device (DC) is fitted to a vehicle (VA) which can be driven by a driver during a manual driving phase and which comprises a passenger compartment (H) fitted with a loudspeaker (HP) capable of diffusing sound signals and an assistance device (DA) for driving said vehicle in a totally autonomous manner during an autonomous driving phase. This device (DC) comprises acquisition means (MA) for recording first sound signals present in the external environment of the vehicle (VA), and control means (MC) for generating, during an autonomous driving phase, second sound signals in phase opposition to the first recorded sound signals, in order to supply same to the loudspeaker (HP) so that the transmission of said signals induces cancellation of the first sound signals in the passenger compartment (H).

(FR)
Un dispositif de contrôle (DC) équipe un véhicule (VA) pouvant être conduit par un conducteur pendant une phase de conduite manuelle et comprenant un habitacle (H) équipé d'un haut-parleur (HP) pouvant diffuser des signaux sonores et un dispositif d'assistance (DA) propre à le conduire de façon totalement autonome pendant une phase de conduite autonome. Ce dispositif (DC) comprend des moyens d'acquisition (MA) propres à enregistrer des premiers signaux sonores présents dans l'environnement extérieur du véhicule (VA), et des moyens de contrôle (MC) propres, pendant une phase de conduite autonome, à générer des deuxièmes signaux sonores en opposition de phase avec les premiers signaux sonores enregistrés, afin de les fournir au haut-parleur (HP) pour que leur diffusion induise dans l'habitacle (H) une annulation des premiers signaux sonores.
