| (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.
