Title (EN) ACTIVE VIBRATION NOISE CONTROL DEVICE
(FR) DISPOSITIF ACTIF DE SUPPRESSION DES BRUITS DE VIBRATION
(JA) 能動型振動騒音制御装置
Abstract:
(EN) An active vibration noise control device (11) is adopted in a vehicle (12) equipped with an EPS motor (5) that drives the vehicle (12) to change the behavior of the vehicle. The active vibration noise control device (11) comprises: an ANC processor (78) that acquires sound information from a fixed point in the vehicle interior as an error signal and performs control so as to suppress vibration noises on the basis of a reference signal correlated with the vibration noises and the error signal acquired; and a back-electromotive-force information acquisition unit (77) that acquires information about the back electromotive force generated in the EPS motor (5) due to a change in the behavior of the vehicle (12). The ANC processor (78) uses the information about the back electromotive force acquired by the back-electromotive-force information acquisition unit (77) as a reference signal. The active vibration noise control device (11) actively suppresses the vibration noises generated in the vehicle (12).
(FR) L'invention concerne un dispositif actif de suppression des bruits de vibration (11) qui est adopté dans un véhicule (12) équipé d'un moteur EPS (5) qui propulse le véhicule (12) en vue de modifier le comportement du véhicule. Le dispositif actif de suppression des bruits de vibration (11) comprend : un processeur ANC (78) qui acquiert des informations sonores à partir d'un point fixe dans l'habitacle du véhicule sous la forme d'un signal d'erreur et effectue une commande de manière à supprimer les bruits de vibration sur la base d'un signal de référence corrélé aux bruits de vibration et au signal d'erreur acquis ; et une unité d'acquisition d'informations de force contre-électromotrice (77) qui acquiert des informations concernant la force contre-électromotrice générée dans le moteur EPS (5) en raison d'un changement du comportement du véhicule (12). Le processeur ANC (78) utilise les informations à propos de la force contre-électromotrice acquise par l'unité d'acquisition d'informations de force contre-électromotrice (77) en tant que signal de référence. Le dispositif actif antibruit de vibration (11) supprime activement les bruits de vibration générés dans le véhicule (12).
(JA) 能動型振動騒音制御装置(11)は、車両(12)の挙動を変化させる駆動を行うEPSモータ(5)を備える車両(12)に適用される。能動型振動騒音制御装置(11)は、車室内の定点での音声情報を誤差信号として取得すると共に、振動騒音に相関する参照信号及び前記取得した誤差信号に基いて、振動騒音を抑制する制御を行うANCプロセッサ(78)と、車両(12)の挙動変化によってEPSモータ(5)に生じる逆起電力の情報を取得する逆起電力情報取得部(77)と、を備える。ANCプロセッサ(78)は、逆起電力情報取得部(77)で取得した逆起電力の情報を参照信号として用いる。能動型振動騒音制御装置(11)は、車両(12)で生じる振動騒音を能動的に抑制する。
