PURPOSE:To enhance the comfortability of drive with the use of a vehicle air-conditioning device in which a correction is made in accordance with the quantity of solar radiation, by restraining the output of a solar radiation quantity detecting means to a predetermined value when night-time is detected. CONSTITUTION:When a control means 7 receives a detection signal from a night-time detecting means 6 for detecting the turn-on of head lamps to know night-time, the control means 7 reduces a solar radiation quantity to be corrected, by a predetermined amount irrespective of the quantity of solar radiation detected by a solar radiation quantity detecting means 1. Accordingly, no solar radiation quantity correcting signal is delivered to a computing means 4 during night-time, and therefore, air-conditioning is made in accordance with output signals from a passenger's compartment temperature detecting means 2 and a temperature setting means 3. Accordingly, air-conditioning during night- time may be made to be appropriate to enhance the comfortability of drive of the vehicle. |
