An engine control apparatus including an interpolation control means comprises an interpolation control unit including a desired value calculation part for calculating a desired value of a controlled variable corresponding to each operational state based on related control parameters; a state determination part for determining a change in the operational state of the engine; a interpolation coefficient calculation part for calculating changes of an interpolation coefficient of the controlled variable; and an interpolated desired value calculation part for calculating the interpolated desired value of the controlled variable based on the interpolation coefficient and two desired values of the controlled variable in the first and second operational states; wherein the interpolation control unit controls the controlled variable in switching of the operational state from the first to the second state in the engine.

[ What is claimed is:] [1.]1. An engine control apparatus comprising:an interpolation control unit including;desired value calculation means for calculating a desired value of a controlled variable corresponding to each operational state based on related control parameters of an engine;determination means for determining changes of an operational state of said engine;interpolation coefficient calculation means for calculating an interpolation coefficient of said controlled variable for an interpolated desired value of said controlled variable between desired values in a first operational state and a second operational state to which said operational state of said engine is switched from said first operational state; andinterpolated desired value calculation means for calculating an interpolated desired value of said controlled variable based on said interpolation coefficient and two desired values of said controlled variable in said first and second operational states wherein said interpolation control unit controls said controlled variable in switching of a required operational state from said first state to said second state in said engine with said interpolated desired value whose changes are obtained by said interpolated desired value calculation means corresponding to an operational state determined by said state determination means and said timing of adding said incremental quantity to a present interpolation coefficient optionally is set by searching a map or a table.
