PROBLEM TO BE SOLVED: To adequately learn the ignition timing of an engine at the refueling of the same. SOLUTION: This controller corrects the control target value of the ignition timing according to a multipoint learning value AGdp [n] for compensating the change part of the ignition timing due to aging of the internal combustion engine and a basic learning value AG [i] for compensating the change part of the ignition timing caused by the other factors. The control target value is corrected with the multipoint learning value AGdp [n] and the basic learning value AG [i] in a multipoint learning region n with a greater influence of the aging of the internal combustion engine to the ignition timing, and it is corrected only with the basic learning value AG [i] in the other regions. Learning of only the multipoint learning value AGdp [n] is permitted in the multipoint learning region n, and learning of only the basic learning value AG [i] is permitted in the other regions. In the case the basic learning value AG [i] is changed (S101:YES), the multipoint learning value AGdp [n] is changed by the amount the same as the change amountΔAG of the basic learning value AG [i] to the direction opposite thereto (S103).
