ABSTRACT:
A learning control method for an electronic engine control system in which a variable concerning the adhesion of injected fuel onto a wall surface of an intake manifold, the evaporation of adhered fuel or the runaway of fuel to a cylinder is determined on the basis of a detection value of the operating state of an engine in accordance with a predetermined relational expression and the quantity of fuel injection is controlled on the basis of the determined value of the variable so that a target air/fuel ratio is realized, comprises the steps of determining the degree of deviation of an air/fuel ratio from the target value after the engine has been turned from a steady operating state into a transient operating state, determining a range in which the detection value of the engine operating state as the base of determination of the variable has changed upon occurrence of a fuel injection quantity control error which causes the deviation of the air/fuel ratio from the target value, and correcting a corresponding relationship between the engine operating state and the variable in the determined range of change on the basis of at least the degree of deviation of the air/fuel ratio from the target value by use of a rule-based inference.
