Abstract
A virtual sound provision apparatus for an electric vehicle includes a driving information detector configured to detect vehicle driving information for outputting a virtual driving sound, a microphone configured to detect an actual driving sound generated from the electric vehicle, a controller configured to determine a characteristic of a target sound based on an acceleration and deceleration driving pattern of a driver from an accelerator pedal input value and a brake pedal input value of the driver, and generating and outputting a sound control signal for outputting the virtual driving sound having the characteristic of the target sound based on the determined characteristic information of the target sound and characteristic information of the actual driving sound, and a sound device configured to output a virtual engine sound that simulates an engine sound from the electric vehicle at the time of acceleration and deceleration according to the sound control signal.
