PURPOSE:To improve responsiveness to a target set cabin temperature by predicting cabin temperature after elapse of the predetermined time when an output signal from a control subject does not change from the start of driving an air conditioning mechanism, and controlling the drive of the air conditioning mechanism on the basis of a difference between the aforesaid cabin temperature and the target set cabin temperature. CONSTITUTION:A control means 42 first predicts cabin temperature after the elapse of the predetermined time (useless time), when an output signal from a control subject (e.g. cabin temperature, diffuser temperature and the like) does not change from the drive start of an air conditioning mechanism 8. Furthermore, the control means 42 makes a comparison between the aforesaid predicted cabin temperature yo(t) and a target set cabin temperature A for the calculation of a deviation from the temperature A, and controls the drive of an air conditioning mechanism 8 to maintain the temperature A on the basis of deviation. According to the aforesaid construction, it is possible to prevent the occurrence of overshooting and hunting (malfunction) for the cabin temperature, due to the effect of the useless time of the air conditioning mechanism 8, and improve the responsiveness to the temperature A. In addition, temperature control is always made to resist an external disturbance and a performance for restraining an external disturbance is improved. |
