PURPOSE:To indicate how the room temperature changes near converging on an aimed temperature by selectively indicating each level of the temperature range, and by determining threshold values of ranges in such a manner as to mask large temperature oscillation around the aimed temperature. CONSTITUTION:Data, sent to a digital computer 13 from temperature sensor 10, 11 located inside and outside of an automobile through a multiplexor 12, are digitalized by a built-in AD converter 14 in the computer 13. The level of each digital signal is indicated selectively on a temperature indicator 23 with classification of seven regions. The threshold values of the ranges are determined in such a manner as to mask excessive temperature fluctuation around the aimed temperature. In consequence, the quick change of air temperature is indicated before the air temperature is converged and, thereafter, it is indicated that the control of air temperature is made stably. |
