Vehicular air conditioning apparatus

摘要

The vehicular air conditioning apparatus according to the present invention has a means of calculating transient points of a model response of the room temperature from a staring point to an end point. The air conditioning apparatus conducts a control that makes the actual room temperature go along the curve of the calculated model response from the current temperature to the new set room temperature. The model response curve of the room temperature is drawn as a gradual, moderately varying curve, so the magnitudes of the correction necessary for each control timings are always small. The air conditioning apparatus can attain the small necessary correction securely for each control cycle. As a total result, a stable and quick change in the actual room temperature can be brought without hunting phenomenon or an excessive delay.
