ABSTRACT:
Disclosed is an electronic learning control apparatus for an internal combustion engine, in which a basic control quantity corresponding to a target control value is corrected and computed by a feedback correction value to determine a control quantity and an objective parameter to be controlled is controlled by a static control quantity through control means. The entire deviation of the feedback correction value from a predetermined reference value is separated into deviations for respective error causes according to predetermined analysis rules, and a learning correction value for each error cause is computed according to the separated deviation for each error cause, and the basic control quantity is corrected based on the learing correction value for each error cause to obtain a final optimum control quantity. In this apparatus, the learning speed is increased and the learning correction precision can be improved.
