PURPOSE:To prevent lowering of sensitivity to an input signal and to stabilize accurate control by a method wherein, in a control device for controlling air- conditioning of a vehicle, an average value of a digital signal is determined, and based on the average value, an input value for computing a control output is corrected. CONSTITUTION:After an input signal A is converted into a digital signal AD by means of a digital converting means P1, an average value ADA of the digital signal AD is computed by means of an average value computing means P3. In relation to the average value ADA, correction means P4 adds a given value to the average value ADA during a change in which a change in the average value ADA to an input value ADH for computing a control output exceeds a given value, and when it is below the given value, by subtracting the given value from the average value, the input valve ADH for computing a control output is computed. By means of the input value ADH for computing a control output, a control output computing means P2 outputs a control output D. This constitution suppresses lowering of sensitivity to an input signal and enables stabilization of accurate control. |
