1. An apparatus for controlling an automobile air-conditioner, comprising:
- (a) a vehicle compartment temperature sensor for detecting a representative temperature in a vehicle compartment;
(b) an upper-part temperature sensor for detecting a temperature of an upper part of the vehicle compartment;
(c) a temperature setter for setting a temperature in the vehicle compartment;
(d) an upper-part temperature setter for setting a temperature of the upper part of the vehicle compartment;
(e) mode doors disposed respectively at a plurality of differently directed outlets for changing the discharge mode of the air-conditioner;
(f) mode control value calculation means for calculating a mode control value concerned in the control of the discharge mode, based on at least the detected representative vehicle compartment temperature and the setting vehicle compartment temperature;
(g) correction means for correcting a changeover criterion based on at least the detected upper-part temperature and the setting upper-part temperature until a deviation of the detected upper-part temperature from the setting upper-part temperature is canceled out;
(h) discharge mode selection means for selecting a discharge mode corresponding to the mode control value, based on the changeover criterion corrected by said correction means; and
(i) drive control means for controlling the operation of said mode doors depending on the result of selection by said discharge mode selection means.

Abstract
An apparatus for controlling an automobile airconditioner includes a discharge mode selection device for selecting a discharge mode depending on the magnitude of a discharge mode changeover criterion signal calculated based on at least a vehicle compartment temperature and a setting temperature, and a correction device for correcting a discharge mode selection criterion based on the temperature of an upper-part of the vehicle compartment and a set upperpart temperature. With this arrangement, the discharge mode selection is carried out with due consideration on the occupant'"'"'s sense of comfortableness in the vicinity of its head.
