초록

Recently, amid the increase in the demand for electric vehicles, many improvements have been made to prevent noise from entering the vehicle's interior. However, the perspective on the change in indoor pressure has been excluded. In this paper, the Standard for the change in indoor pressure, which can cause discomfort to the human body, was set, and the change in indoor pressure that could occur while driving was measured. The Extractor Grille area was increased by 20 cm2 and tested from 0 cm2 to 200 cm2. For each Extractor Grille area, the driving speed was increased by 20 km/h, and the indoor pressure difference that occurred while the vehicle was in Operation from 60 km/h to 180 km/h was calculated. Through this experiment, we discovered that the Extractor Grille area has a significant impact on the indoor pressure generated during the drive, and such indoor pressure generated while driving can cause physical discomfort to the driver. © 2025 Korean Society of Automotive Engineers.
