Title:
METHOD AND DEVICE FOR CONTROLLING AIR CONDITIONING FOR VEHICLE
Document Type and Number:
Japanese Patent JP3388136
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To perform the optimal air conditioning control in consideration of a load by the outside air even in the case where an outside air sensor is not provided by estimating the outside air temperature on the basis of the inside air temperature, and computing a target blow-out temperature on the basis of the estimated value.
SOLUTION: Inside air temperature signal Ti from an inside air sensor, which is provided in a cabin, is used as an initial value of the estimated outside air temperature Tam to be estimated first, and a balance temperature TBAL is computed on the basis of a formula I. Target blow-out temperature TOC is computed on the basis of a formula II. This computed target blow-out formula TOC is used, and the estimated outside air temperature Tam is computed for estimation. At this stage, Tset means the set temperature, and (a), (b), (c), (d), (e), (f), (g) respectively means a previously set constant, and TLC means a sunshine corrected value. This estimated outside air temperature Tam is used so as to compute the balance temperature TBAL on the basis of the formula I again, and this TBAL is used so as to compute the target blow-out temperature TOC on the basis of the formula II.
