PURPOSE: To diagnose and display the normality degree of an item to be diagnosed by fuzzy inference. CONSTITUTION: The output voltage H/W of a hot wire type flow meter is inputted, the normality degree mH/W of the hot wire type flow meter is retrieved from a map stored as a fuzzy amount, the normality degree mH/W is compared with a minimum normality degree minH/W retrieved in the past, and when it is smaller, the minimum value minH/W is updated by the normality degree mH/W (S1-S4.) The minimum value minH/W updated in such a manner is displayed by digital signals. |
