Abstract

An atmospheric pressure detector of an internal combustion engine (1), wherein intake pressures PMi [mmHg] at crank angular positions in increments of 30 [°CA (Crank Angle)] after the start of the internal combustion engine (1) are detected and the detected intake pressures RMi are uniformed according to a transition state to provide an atmospheric pressure and, when a difference ΔPM between the maximum value PMMAX and the minimum value PMMIN of the plurality of intake pressures PMi is as small as within a specified value, these plurality of intake pressures PMi are uniformed, whereby, since the atmospheric pressure when the intake pressures PMi are stable can be provided by a plurality of samplings at these crank angular positions, the reliability of the atmospheric pressure can be increased.
