Abstract: Convenience features and performances are required to meet the diverse and sophisticated requirements of consumers including technological advances. We classified the seating positions into the normal seating typically preferred by the driver, right sitting, and lying seating position through subjective evaluation, and tested with the same person depending on the different seating positions. For the test equipment, constant temperature and humidity chamber were used to reproduce the environmental conditions. As a result, it was found that the driver’s sitting position affects the flow loss. The average temperature was less than Cush 0.7℃/Back 0.3℃, and the normal sitting position showed relatively high performance. Consequently, it was confirmed that the seat surface temperature with no driver was influenced by the ambient temperature of the chamber even when the ventilation system was turned on.
