초록

자동차 고급화 추세에 따라 소비자의 차량 실내 환경에 대한 관심이 증가함에 따라 자동차의 기본적 성능뿐만아니라 실내 쾌적성 향상에 관심이 증대되고 있다. 또한 자동차 실내 쾌적성에 대한 연구는 운전자에게 만족을 제공하는데 그치지 않고, 운전자의 불쾌지수 및 스트레스를 낮추어서 교통사고의 위험을 줄이는데 기여할 수 있기 때문에 매우 중요한 연구 주제이다. 따라서 본 연구에서는 운전자의 뇌파측정을 통해 통풍시트의 온도변화에 따른 쾌적감 변화와 쾌적온도를 알아보고, 온도변화에 따른 남녀간 쾌적감에 대한 차이를 탐색하고자 하였다. 연구결과 첫째 통풍시 트의 온도가 22℃, 25℃, 28℃에서 각각의 실험군을 비교한 결과 28℃보다 25℃에서 통계적으로 유의하게 쾌적감이 더 높게 나타났다. 둘째 통풍시트 온도 변화에 따른 남녀간 쾌적감에 대한 실험결과 남성과 여성이 온도에 따라 느끼는 쾌적감은 통계적으로 유의한 차가 없는 것으로 나타났다. 향후 자동차의 실내온도와 통풍시트의 온도 변화에 따른 운전자의 쾌적감 변화를 파악하여 상관관계를 분석한다면, 운전자의 쾌적성을 확보하여 휴먼에러로 인한 교통사고를 낮출수 있을 뿐만 아니라 자동차의 전기에너지의 사용량을 줄일 수 있을 것이다.

As the number of automobile registrations increases and luxury expectations grow, consumers are increasingly interested in indoor environment of vehicles. Therefore, manufacturers have an increasing interest in improving the indoor comfort as well as automobile performance. Research on indoor automobile comfort can help manufacturers increase driver satisfaction and reduce driver stress and discomfort, thereby reducing the risk of traffic accidents. Using electroencephalogram (EEG) measurements, we investigated the change in comfort and comfortable temperature according to the ventilating seat temperature change for both men and women. Results showed that the sensation of comfort was statistically significantly higher at 25℃ than at 28℃. Secondly, there was no statistically significant difference in temperature-based comfort feeling between male and female subjects. In the future, if the correlation between the driver's comfort feeling and the change in ventilating seat temperature is analyzed, it is possible to reduce traffic accidents caused by human error and reduce the electric energy consumption of the automobile.
