METHOD OF CONTROLLING IN-VEHICLE DRIVING SOUND USING SOUND QUALITY INDEX-BASED GENERATIVE AI

Abstract

A method of controlling sound using a sound quality index-based generative artificial intelligence (AI) of the present disclosure includes inputting a controller area network (CAN) signal and a vibration signal of a vehicle to a neural encoder, forming, by a controller, a latent vector for the CAN signal and vibration signal processed in the neural encoder, outputting, by the latent vector, sound through a neural decoder, and outputting a sound quality index (SQI) through a neural network, wherein the neural decoder may fixedly use the parameters of the neural decoder of which training is completed, the neural network may fixedly use the neural network of which training is completed from the input of the CAN signal and vibration signal of the vehicle, and the neural encoder may be trained while the sound quality index output through the neural network is compared with a target sound quality index.
