Title:
車両の異音検査装置
Document Type and Number:
Japanese Patent JP7392633
Kind Code:
B2
Abstract:
A storage device of a noise inspection apparatus is configured to store a neural network machine-learned to receive, as inputs, an original sound characteristic value indicating a characteristic of sound generated by a transmission and an evaluation sound characteristic value indicating a characteristic of sound that reaches a vehicle cabin, and output a route part characteristic value that is a value indicating a characteristic of a vibration transfer of a vehicle part positioned on a vibration transfer route from the transmission to the vehicle cabin. An execution device of the noise inspection apparatus is configured to calculate, as an estimated value of the route part characteristic value, an output of the neural network that has received, as inputs, measured values of the original sound characteristic value and the evaluation sound characteristic value.
