Problems solved by technology

[0003] However, the conventional virtual engine sound system controls the volume of the virtual engine sound according to the vehicle speed, so that when the noise around the vehicle is relatively high (for example, in urban areas, market areas, or sightseeing areas), pedestrians may not be able to perceive the approach of the vehicle

Abstract

A virtual engine sound system for a vehicle and a method for controlling the system are provided. The method includes detecting data for determining volume of the virtual engine sound and determining whether an output condition of the virtual engine sound is satisfied based on the data. In addition, the method includes determining a sound source to be played back when the output condition of the virtual engine sound is satisfied and determining the volume of the virtual engine sound based on a noise level extraneous to the vehicle. The virtual engine sound that corresponds to the determined volume is then output.

Description

technical field [0001] The present invention relates to a virtual engine sound system for vehicles and a method of controlling the system. More particularly, the present invention relates to a virtual engine sound system that controls the volume of a virtual engine sound according to a noise level around a vehicle, and a method of controlling the system. Background technique [0002] In general, hybrid vehicles, electric vehicles, and fuel cell vehicles, which are generally called environment-friendly vehicles, are driven by drive motors that generate torque using electrical energy. When the eco-friendly vehicle is driven using only the drive motor, the noise generated from the eco-friendly vehicle is so low that pedestrians may hardly notice the approach of the vehicle. As a countermeasure, a virtual engine sound system (VESS: Virtual Engine Sound System) that outputs a virtual engine sound through a speaker to make pedestrians aware of an approaching vehicle has been deve...
