Abstract: <P>PROBLEM TO BE SOLVED: To provide a control system of an internal combustion engine which controls an abrupt change of an engine operating state due to misexecution of correction to an engine state quantity during engine operation caused by misjudgement of stop of engine operation besides suppressing the deterioration of control precision in an engine state quantity resulting from an error in a change history of the engine state quantity.  <P>SOLUTION: Besides computing a position counter value on the basis of output signals of position sensors S1, S2, the maximum lift amount of an intake valve is computed on the basis of a position counter value. An error of the position counter value is detected by comparing output signals of the position sensors S1, S2 with output signals of electric angle sensors D1-D3. On the condition that a state where engine rotation speed detected by a crank angle sensor 74 is smaller than a threshold value is continued for a predetermined period, it is judged that an internal combustion engine is stopped. On the basis of the error of the position counter value, a final value of the maximum lift amount is corrected to be stored as an initial value at next engine start.  <P>COPYRIGHT: (C)2008,JPO&INPIT
