AB  - With the increasing adoption of electric vehicles (EVs), the number of vehicles equipped with active sound design (ASD) systems has also grown. Although many EV driving sounds emulate the acoustic characteristics of internal combustion engine (ICE) vehicles, EVs lack engine induced vibrations, resulting in a mismatch between auditory cues and tactile seat sensations. Providing vibrations synchronized with virtual engine sound can mitigate this discrepancy and enhance driver immersion. This study analyzes the seat vibration characteristics of an ICE vehicle and proposes a vibration generation algorithm that integrates vehicle state information with already existing ASD sound. The algorithm was implemented on a DSP platform, and vibration actuators were installed in an EV seat to deliver tactile feedback in conjunction with ASD sound.
