る。The feeling of stuffiness of the whole body is composed of two factors, the discomfort index DI and the water vapor pressure Pab at the contact portion between the occupant and the backrest of the seat as shown in the above equation (1), and as described with reference to FIG. Approximately 81% of the stuffiness can be explained by these two factors.

との接触部に起因する蒸れ感とに分離する。Looking at this equation (1) in more detail, the first term containing the discomfort index DI is the temperature and humidity feeling in the passenger compartment, and the second term containing the water vapor pressure Pab is the contact area between the occupant and the backrest of the seat. Represents the sense of temperature and humidity in, and is a formula in which both are linearly added. Therefore, paying attention to this additivity, the stuffy feeling is separated into a stuffy feeling due to the vehicle interior environment and a stuffy feeling due to the contact portion with the seat back portion.

と背もたれ部における水蒸気圧との関係を調べた。In separation, it is assumed that the stuffy feeling generated at the contact portion between the occupant and the backrest of the seat is caused only by the temperature and humidity feeling of the backrest, and the sensory value at this time is set to 0 when there is no feeling of humidity. It was set as 1 having a slight sense of humidity, 2 having a sense of humidity, and 3 having a very sense of humidity. Further, assuming that the feeling of dampness is caused only by the influence of the vehicle interior environment when the humidity feeling of the backrest is 0, the relationship between the humidity feeling of the backrest and the water vapor pressure in the backrest was investigated first.

暖房装置を制御して温度を制御するようにしてもよい。FIG. 6 shows the relationship between water vapor pressures at both the seat portion and the backrest portion. According to FIG. 6, the correlation coefficient R between the water vapor pressures of the backrest and the seat is 0.8.
As high as 64, the water vapor pressure in the seat tends to increase as the water vapor pressure in the backrest increases. This result suggests that either the backrest portion or the seat portion may be evaluated for the stuffiness of the contact portion between the occupant and the seat depending on the water vapor pressure. As a result of comparing the two parts, since the water vapor pressure tends to be higher in the backrest portion, in the present embodiment, the water vapor pressure in the contact portion between the occupant and the seat back portion is used to determine the contact portion between the seat back portion and the seat back portion. We decided to evaluate the stuffiness, but of course the temperature and humidity of the contact area between the occupant and the seat of the seat were detected to calculate the water vapor pressure at the contact area with the seat, and the stuffiness of the contact area with the seat area was calculated. Feeling may be evaluated by comparing the vapor pressures of the backrest and seat, and the vapor pressure of the larger one, or the average of the vapor pressures of both parts, to determine the stuffiness of the contact area between the occupant and the seat. It goes without saying that you can evaluate it. Even in this case, it is judged whether the stuffy feeling of the whole body contributes much to the passenger compartment, the seat back portion, or the seat portion of the seat, the air conditioner is controlled, the seat back portion and the seat portion are controlled. You may make it control the temperature by controlling the cooling / heating device provided in the seat part.

Although t, the estimated steaminess value Ms in the passenger compartment and the estimated steaminess value Mc in the contact portion are calculated according to the equations (1), (5), and (6), the present invention is not limited to these equations. Instead of this, an optimal formula according to the region and environmental conditions obtained by experiments, an appropriate formula according to the age of the occupant, sex, etc., or a simplified formula may be used.
