Abstract

PURPOSE:To improve the control of temperature, by shifting an air mix door to a calculated degree of opening when a deviation due to hysteresis control has lasted between the detected degree of opening of the air mix door and the calculated degree of opening for a prescribed time. CONSTITUTION:A variable resistor 26 is provided to set the temperature of a vehicle room. The detection outputs of temperature sensors 22, 24 which detect the temperatures inside and outside the vehicle room and an opening degree sensor 28 which detects the degree of opening of an air mix door 5 are entered into a microcomputer to perform digital operation and processing to regulate the temperature of the vehicle room to a set level on the basis of a prescribed control characteristic. When a deviation due to hysteresis control has lasted for a prescribed time between the degree of opening detected by the sensor 28 and a degree of opening calculated by the operation and processing, a control signal is applied to the driving means of the air mix door 5 to regulate the door to the calculated degree of opening.
