Abstract
The present invention provides a vehicle sound generator apparatus comprising a vehicle state sensing unit, a storage unit comprising a sound source storage unit and a reference data storage unit, a sound source playback unit, a sound source amplification unit, a sound output unit, and a control unit. The vehicle state sensing unit senses a vehicle speed, and the control unit calculates a corresponding shifting factor from the velocity shifting profile to correspond to the vehicle speed, and controls and outputs the sound pressure or the pitch of the operating sound. The present invention generate and control a virtual operating sound, which reflects a change in vehicle speed and time to generate a virtual sound that imitates a real internal combustion engine sound while increasing recognizability of a pedestrian so that the vehicle operating sound can be transferred to the driver and pedestrian to further secure safety of the pedestrian.
