Claim One:
1. An electronic learning control apparatus for an internal combustion engine, which comprises: engine driving state detecting means for detecting the driving state of the internal combustion engine; basic control quantity setting means for setting a basic control quantity corresponding to a target control value of an objective control factor; feedback correction value setting means for comparing the actual control value with the target control value and setting a feedback correction value for bringing the actual control value close to the target control value by increasing or decreasing the actual control value; rewritable learning correction value storing means for storing a learning correction value for each of a plurality of error causes, control quantity computing means for computing a control quantity by making a correction based on the learning correction value for each of the error causes according to a computing formula set for each of the error causes; control means for controlling the objective control factor of the internal combustion engine according to the computed control quantity; entire deviation detecting means for detecting the entire deviation of the feedback correction value from a predetermined reference value; error cause analyzing means for analyzing qualitatively and quantitatively a cause for producing an error in said entire deviation according to a predetermined analysis rule and separating the entire deviation into deviations of the respective error causes based on the analysis results; learning correction value setting means for computing and setting the learning correction value of each error cause based on the deviation of each error cause; and learning value renewal means for rewriting the learning correction value of each error cause stored in said storing means based on the set learning correction value of each error cause.
