Abstract
A virtual engine sound system for a vehicle includes: a speaker mounted on an intake system, and generating an anti-noise sound with inverted phase to an engine noise of an internal combustion engine or a virtual sound; and a valve which is movable between an open position in which an outlet of an air cleaner is opened and a closed position in which the outlet of the air cleaner is closed. The speaker is controlled by an ECU, and the valve is controlled by a valve controller. The ECU controls the speaker to generate the anti-noise sound in an operating condition in which the internal combustion engine is operating, and controls the speaker to generate the virtual sound in an operating condition in which the internal combustion engine is not operating.
