<p>PURPOSE:To obtain stability in a control system, by monitoring the change in the temperature in an automobile, getting a difference between a value which is expected to converge according to the monitored temperature change and the target value and effecting repeatedly correction to the air conditioning capabilities of an automobile air conditioner in response to the difference. CONSTITUTION:A microcomputer 21 is provided to control the driving of a blower 11, air-mix damper 14, etc. installed in an air conditioning duct 10. This microcomputer 21 issues control signals based on outputs from inside and outside air temperature sensors 15 and 16, a sun shine sensor 17, and room temperature and air flow rate setting devices 18 and 19. Namely, the microcomputer 21 seeks the temperature regulation value in order to stabilize the inside temperature to the target value by the outputs from sensors and setting devices, and issues instruction signals to each of the driving circuits 23 and 24 according to this regulation value. Further, the microcomputer 21 seeks from the state of change in the inside air temperature its convergent value that is expected to stabilize by this adjustment control and it is operated to correct the external disturbance parameter according to the difference between this value and the target value.</p> |
