Abstract
An engine control apparatus which may be employed in automotive vehicles. The engine control apparatus is equipped with a controlled variable arithmetic expression which defines correlations between combustion parameters associated with combustion conditions of an engine and controlled variables actuators for an operation of the engine. This eliminates the need for finding relations of optimum values of the controlled variables to the combustion parameters through adaptability tests, which results in a decrease in burden of an adaptability test work and a map-making work on manufacturers. The engine control apparatus also works to learn or optimize the controlled variable arithmetic expression based on actual values of the combustion parameters, thereby avoiding undesirable changes in correlations, as defined by the controlled variable arithmetic expression, due to a change in environmental condition.
