US 2026/0249937 A1 · DETECTION SYSTEM, DETECTION METHOD, AND METHOD FOR MANUFACTURING MOBILE BODY

Abstract

To provide a detection system, a detection method, and a method for manufacturing a mobile body each adapted to improve the detection accuracy of an anomalous sound. A detection system includes: a noise data acquisition unit, a canceling sound generation unit, a speaker control unit, a recorded data acquisition unit, and an anomalous sound detection unit. A noise data acquisition unit is configured to acquire noise data. A canceling sound generation unit is configured to generate, based on the noise data, a canceling sound. A speaker control unit is configured to control a speaker apparatus so as to reproduce the canceling sound. A recorded data acquisition unit is configured to acquire recorded data. An anomalous sound detection unit is configured to detect, from the recorded data, an anomalous sound.

Dependent claims

A detection system comprising:

a noise data acquisition unit configured to acquire noise data related to noise outside a mobile body;
a canceling sound generation unit configured to generate, based on the noise data, a canceling sound for canceling the noise;
a speaker control unit configured to control a speaker apparatus so as to reproduce the canceling sound inside the mobile body;
a recorded data acquisition unit configured to acquire recorded data recorded inside the mobile body in which the canceling sound is reproduced;
and
an anomalous sound detection unit configured to detect, from the recorded data, an anomalous sound which is a sound associated with an abnormality of the mobile body.
