PURPOSE:To make improvements in display accuracy, by displaying the measured value immediately after engine starting, and afterward constituting it so as to perform a display alteration only at a time when the measured value side is higher than the displayed temperature and such a state that a car speed exceeds the setting one continues for more than the specified time long. CONSTITUTION:After engine starting, an outside temperature sensor starts the measurement of outside temperature. And the first measured value A is displayed on a display part B. And, the subsequent measured value A' is compared with a displayed temperature B, and if this measured value A' is less than the display value B, no alteration for this display B takes place. And, when the measured value A' is larger than the display temperature B, that whether a car speed exceeds the specified one or not is studied, and the display temperature B is altered only at a time when such a state that is goes beyond the specified car speed continues for more than the specified time long. With this constitution, such a temperature display as being affected by the car speed is avoidable, thus display accuracy is improved. |
