Abstract
(EN) When a moving body (MV) is stopped, a sound output control unit (750A) determines whether a person is detected in the surroundings of the moving body (MV) by a human detection unit (730). When the results of the determination are positive, the sound output control unit (750A) determines whether a leaking sound of an inside sound to the outside of the moving body (MV) can be recognized by a detected person on the basis of the inside sound and an outside sound detected by a moving body outside sound detection unit (710) and a moving body inside sound detection unit (720) for the moving body (MV). If the results of this determination are positive, the sound output control unit (750A) extracts environmental sound that does not include the leaking sound on the basis of the outside sound and inside sound. Furthermore, the sound output control unit (750A) carries out control in which environmental sound is output by a sound output unit (790). A sound output unit (210) outputs environmental sound according to control by a control unit (150A). Therefore, environmental sound that does not annoy people in the surroundings of the moving body (MV) is output and the degree of recognition of leaking sound outside of the vehicle can be reduced.
(FR) La présente invention concerne le cas où, lorsqu'un corps mobile (MV) est arrêté, une unité de commande de sortie de son (750A) détermine si une personne est détectée dans l'environnement du corps mobile (MV) par une unité de détection d'humain (730). Lorsque les résultats de la détermination sont positifs, l'unité de commande de sortie de son (750A) détermine si une fuite sonore d'un son interne vers l'extérieur du corps mobile (MV) peut être reconnue par une personne détectée sur la base du son interne et d'un son externe détecté par une unité de détection de son (710) à l'extérieur du corps mobile et une unité de détection de son (720) à l'intérieur du corps mobile pour le corps mobile (MV). Si les résultats de cette détermination sont positifs, l'unité de commande de sortie de son (750A) extrait le son ambiant qui n'inclut pas la fuite sonore sur la base du son externe et du son interne. De plus, l'unité de commande de sortie de son (750A) réalise une commande dans laquelle le son ambiant est produit par une unité de sortie de son (790). Une unité de sortie de son (210) produit un son ambiant en fonction de la commande émise par une unité de commande (150A). Par conséquent, le son ambiant qui ne gêne pas les personnes dans l'environnement du corps mobile (MV) est produit et le degré de reconnaissance de la fuite sonore en dehors du véhicule peut être réduit.
(JA)  移動体MVが停止中のときに、音出力制御部750Aは、人検出部730により移動体MVの周囲に人が検出されたかを判定する。判定の結果が肯定的である場合に、音出力制御部750Aは、移動体外音検出部710及び移動体内音検出部720により検出された移動体MVの「内部の音」及び「外部の音」に基づいて、検出された「人」により移動体MVの内部の音の外部への「漏れ音」が認識され得るか判断する。当該判断の結果が肯定的である場合に、音出力制御部750Aは、外部の音及び内部の音に基づいて、漏れ音が含まれない「環境音」を抽出する。そして、音出力制御部750Aは、音出力部790から環境音を出力させる制御を行う。音出力部210は、制御部150Aの制御に従い、環境音を出力する。このため、移動体MVの周囲の人に迷惑をかけない環境音を出力して、車外への漏れ音の認識度を低減させることができる。
