(54) Control Apparatus and Method for Internal Combustion Engine


(57) A control apparatus for an internal combustion engine, which comprises storage means for storing a data map where a plurality of scale values for the intake pressure in the internal combustion engine are associated respectively with a plurality of control amounts for a predetermined control parameter of the internal combustion engine; and scale value rewriting means for rewriting each of the plurality of scale values corresponding to the plurality of control amounts in the data map with a value based on a detected value of the atmospheric pressure. The control amount in the data map corresponding to a detected value of the intake pressure is set as a control amount of the predetermined control parameter, and the control parameter of the internal combustion engine is controlled based on the set control amount, thus reducing the load of an arithmetic element that performs operations for setting the control amount of the engine in accordance with a detected value of an intake air amount.
