Title (EN) METHOD AND APPARATUS FOR ENHANCING VEHICLE SOUND AND/OR VIBRATIONS
(FR) PROCÉDÉ ET APPAREIL POUR AMÉLIORER LE SON ET/OU LES VIBRATIONS D'UN VÉHICULE
Abstract:
(EN) Sound and/or vibration in a vehicle (10) is enhanced by using at least one active powertrain mount (24, 26) to selectively generate vibrations in the vehicle body (12), at least some of which are audible to a person in a cabin of the vehicle. The method can be used to enhance the sound and feel of the vehicle powertrain. The active powertrain mounts typically include at least one active engine mount (24) but may also include at least one active transmission mount (26). The active mounts (24, 26) are controlled by an ECU to attenuate unwanted powertrain vibrations in the usual way whilst simultaneously generating vibrations in the vehicle body to augment desirable engine sounds/vibrations.
(FR) L'invention a pour objet d'améliorer le son et/ou les vibrations dans un véhicule (10) en utilisant au moins un support de groupe motopropulseur actif (24, 26) pour générer sélectivement des vibrations dans la carrosserie du véhicule (12), dont au moins certaines sont audibles pour une personne dans un habitacle du véhicule. Le procédé peut être utilisé pour améliorer le son et la perception du groupe motopropulseur de véhicule. Les supports de groupe motopropulseur actifs comprennent généralement au moins un support de moteur actif (24), mais peuvent également comprendre au moins un support de transmission actif (26). Les supports actifs (24, 26) sont commandés par un ECU pour atténuer des vibrations indésirables du groupe motopropulseur de la manière habituelle tout en générant simultanément des vibrations dans la carrosserie du véhicule pour augmenter les bruits/vibrations souhaitables du moteur.
