Abstract
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.
