Patent ID: 8340926

Claim:
An internal combustion engine control apparatus, having a thermal air flow rate measuring apparatus which measures the flow rate of air flowing through an intake passage on the basis of a signal from a heating resistor, comprising: storage means for storing a plurality of conversion tables used to convert a signal of the heating resistor to an air flow rate; selection means for selecting a conversion table to be used for the conversion from the plurality of conversion tables stored in the storage means; and conversion means for converting a signal of the heating resistor into an air flow rate by referring to the conversion table selected by the selection means; wherein the selection means performs selection of the conversion table according to a state value which directly or indirectly indicates the state of air flow pulsation generated in the passage; and wherein among the forward air flow rate and the reverse air flow rate, the steady table is set to be used only for the conversion of the forward air flow rate.
