Assignee: HYUNDAI MOBIS CO., LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC B  G | IPC B  G

Claim 8:
9. A device for locating a noise occurring in a steering system, the device comprising:
a sound receiving unit configured to detect noise occurring in the steering system;
a processing unit configured to input data on the noise in the steering system into a neural network model that is configured to perform learning in advance and to locate a position or a component at which the noise occurs in the steering system, the noise being detected by the sound receiving unit; and
a storage unit in which the neural network model that is configured to perform the learning in advance is stored,
wherein the processing unit is configured to perform pre-processing of applying a Mel-Frequency Cepstrum Coefficient (MFCC) technique to the data on the noise in the steering system, to extract a frequency feature of the noise in the steering system, and to generate the extracted frequency feature as an image, the noise being detected by the sound receiving unit, and to input the image generated by the pre-processing into the neural network model.
