Method of controlling operating amounts of operation control means for an internal combustion engine

A method of controlling an operating amount of an operation control system for controlling the operation of an internal combustion engine wherein the operating amount is controlled on the basis of first and second desired operating amounts determined in dependence on respective first and second operating parameters indicative of engine load conditions, respectively, when the engine is operating in a predetermined low load condition, and when the engine is operating in another operating condition. When the engine has entered the predetermined low load condition from an operating condition other than the predetermined low load condition, a correction value of the operating amount is obtained on the basis of the difference between the determined first and second desired operating amounts, to correct the determined first desired operating amount. The corrected first desired operating amount is compared with the determined second desired operating amount. The desired operating amount is controlled on the basis of the determined second desired operating amount, from the time the engine has entered the predetermined low load condition to the time the corrected first desired operating amount becomes substantially equal to the determined second desired operating amount, whereas it is controlled on the basis of the corrected first desired operating amount after the corrected first desired operating amount becomes substantially equal to the determined second desired operating amount until the engine enters an operating condition other than the predetermined low load condition.
