Abstract

The present invention relates to a system for controlling noise of a vehicle and a method thereof. A system for controlling noise of a vehicle includes: an engine speed sensor configured for detectinga speed of an engine of the vehicle; a microphone detecting noise of the vehicle; an engine state sensor configured for detecting an operating state of the engine; a signal processing controller receiving the speed of the engine, the noise of the vehicle, and the engine operating state and generating amplified noise based on at least one of the received engine speed, the received noise of the vehicle, and the received engine operating state; a signal processing amplifier receiving the engine speed and the amplified noise and generating output noise by amplifying the amplified noise as much asamplification degree based on the speed of the engine; and a sound transmitting device receiving the output noise and transmitting the output noise or a separate sound source corresponding to the output noise to the vehicle.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2018-0119892 filed on October 8, 2018, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to a system for controlling noise of a vehicle, and more particularly, to a system configured to control a vehicle based on an engine operating state such as engine vibration or engine combustion pressure and a vehicle driving state such as a throttle opening amount. A system for controlling the noise of a vehicle. Background technique [0004] Generally, studies on noise of vehicles can be classified as studies on how to reduce noise from noise sources, how to use sound absorbing materials to cancel noise, and how to use Active Noise Control (ANC) to cancel noise. ANC is a technique for reducing vehicle noise, and controls noise having a booming bandwidth of 250 Hz or less...
