PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine which can improve the precision of absolute pressure correction for correcting an internal pressure detected value in a cylinder to the absolute pressure.SOLUTION: The control device of the internal combustion engine includes: a specifying means for specifying a plurality of combinations of respective crank angles &thetas;, &thetas;of optional two points during an adiabatic period from IVC of a prescribed cylinder till an ignition period; a cylinder internal pressure detection means for respectively detecting the internal pressure detected values in a cylinder P, Pin respective specified crank angles &thetas;, &thetas;; an absolute pressure correction value calculation means for respectively calculating absolute pressure correction value, (PVPV)/(V-V) to the combination of the plurality of the crank angles &thetas;, &thetas;specified by the specification means when the cylinder volume of the prescribed cylinder in the crank angles &thetas;, &thetas;are respectively defined by V, V; an average value acquisition means for acquiring the average value of the plurality of calculated absolute pressure correction value; and an absolute pressure correction means for correcting the internal pressure detected value in a cylinder using the average value. |
