AIR CONDITIONING CONTROL DEVICE FOR AUTOMOBILE

PURPOSE:To improve an air conditioning feeling by a method wherein an azimuth of solar radiation is computed based on solar radiation amounts on both sides of the interior of a car room to control distribution of air to both sides, and when no solar radiation is effected during a time exceeding a given time, control of air distribution is released. CONSTITUTION:Solar radiation amounts of both sides of the interior of a car room are respectively detected by solar radiation sensors 26R and 26L. Meanwhile, the distribution of an amount of air discharged through discharge ports on both sides of the interior of a car room is changed by means of an air distribution door 24. Based on a detected solar radiation amount, an azimuth of solar radiation is computed by a means 300, and a solar radiation amount of the interior of a car room is computed by a means 400. Based on a computed azimuth, an air distribution control range is computed by a means 500, and according to the computing result thereof, the air distribution door 24 is driven and controlled by means of a means 600. Further, when a state that a computed solar radiation amount is below a given value is continued for a time exceeding a given time, control air distribution by means of the means is released by a means 700.
