Abstract
A method of playing a virtual after-burn sound in an electric vehicle is provided. The method includes acquiring driver tendency information generated based on information of music played in a mobile phone and collecting driving variable information for playing a virtual sound during operation of the electric vehicle. Additionally, characteristics of a virtual after-burn sound are determined based on the collected driving variable information. The characteristics of the virtual after-burn sound are corrected according to the acquired driver tendency information. An after-burn signal is generated for playing the virtual after-burn sound based on information about the corrected characteristics of the virtual after-burn sound and operation of sound equipment is adjusted according to the created after-burn signal such that a virtual after-burn sound discriminated according to the driver tendency is played and output from the sound equipment.
