PROBLEM TO BE SOLVED: To provide a vehicle control apparatus capable of suitably learning a plurality of learning values. SOLUTION: The apparatus performs correction of an ignition timing by a feedback correction term and a learning value learned, based on the feedback correction term to set an ignition timing command value. A fundamental learning value AG [i] in a fundamental learning region and a multipoint learning value AGdp [n], in a multipoint learning region are defined as a learning value to update each learning value through a learning process carried out in a given cycle. When there is a history in which the fundamental learning value AG [i (i=1)] has changed at a given number of times of CT or more, the learning is determined as being completed to carry out a preferential learning process for permitting the learning of the multipoint learning value AGdp [n] to be practiced and a guard process for restricting change in the fundamental learning value AG [i] by means of an upper-limit guard value GD. Also when the fundamental learning value AG [i (i=1)] has reached the upper-limit guard value GD with the history absent, the learning is determined as being completed to permit the learning of the multipoint learning value AGdp [n] to be carried out (at time t2).
