Problems solved by technology

Here, when the vehicle enters a high RPM area, a distortion phenomenon occurs due to the excessive use of the current of the amplifier, thereby generating harmonic components, thus generating unnecessary noise in the vibration generator and the vehicle body

Abstract

The present disclosure relates to a system for controlling internal sound of a vehicle. The system phase-changes a frequency of additional sound based on an engine operating state to increase a current density, thereby suppressing signal distortion by increasing the current density. Accordingly, a distortion phenomenon caused by excessive use of amplifier current when additional sound is generated is reduced or minimized, and generation of unnecessary noise in the vibration generator and a frame of the vehicle is suppressed.

Description

technical field [0001] The present disclosure relates to a method and system for controlling the interior sound of a vehicle. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] Recently, development of new technologies for electric vehicles and hybrid vehicles has been ongoing both at home and abroad. Accidents may occur due to the driver not being aware of the driving sensation while driving the vehicle. Therefore, electric vehicles and hybrid vehicles should have a minimum level of noise standards when driving. [0004] In addition, in addition to electric vehicles and hybrid vehicles, even ordinary vehicles generate engine sound and exhaust sound and additional driving sounds at high speeds to create a sporty driving feeling at high speeds. [0005] The running sound is generated separately by analyzing the engine speed, engine torque, vehicle sp...
