PURPOSE:To make it possible to control a car engine steadily by correcting a table by means of interpolation calculated value based on the adjacent table values of learning table values when a difference in the number of learning between the adjacent domains of learning progression table exceeds a fixed value. CONSTITUTION:When PMU27 judges the state of an engine operation to be normal on the basis of previously determined judgmental conditions, PMU27 introduces information from a sensor into the learning value table of RAM31 as learning value, and uses it as control variable for operation control. In addition, learning progression is recorded in a learning progression table corresponding to the learning value table, and when the learning progression at the above corresponding position differs from that in adjacent tables over a fixed value, interpolation calculated value obtained from the two adjacent learning value tables is rewrited for the table value being late in the learning as the learning value at the above corresponding position to correct dispersion in the learning value due to difference in the learning progression. thus, steady engine control can be carried out.
