KR960021620A - Air conditioning control device of vehicle using fuzzy function - Google Patents

Abstract

The air conditioning control device of the vehicle using the fuzzy function of the present invention improves the air conditioning control function of the vehicle by using the fuzzy function, and also controls the indoor air of the vehicle more comfortably. And there is a limit in improving the control characteristics such as responsiveness, in addition to the constant deviation of the set temperature in the steady state in a region other than a specific environment may require a lot of experience and experimentation. The present invention detects the deviation and the sum of the deviation between the set value and the detection value of the sensors to determine the degree of belonging as a membership function, determine the control value for the belonging determined by the fuzzy rule, the suction damper, By determining and controlling the operation amount of the blower motor, air mixing damper and mode damper, the compensation is continuously compensated by the sum of the deviation even if the magnitude of the deviation is small, thus ensuring good air conditioning control performance under all environmental conditions. Excellent responsiveness can keep the indoor air of the vehicle in a comfortable state at all times.
