PURPOSE:To enhance response and stability of air-fuel ratio control, by providing a condition correcting value determining means for producing a condition correcting value signal repeatedly and a fuel supply control means for correcting a signal representing a base fuel supply rate. CONSTITUTION:A condition correcting value determining means 23 applies a signal representing the frequency of determining a condition correcting value to a control gain value rewriting means 25 and a delay time rewriting means 51. The delay time rewriting means 51 rewrites the dalay time to increase it with increasing of the frequency of determining the condition correcting value. On the other hand, a fuel supply control means 24 corrects a signal representing a base fuel supply rate on the basis of a condition correcting value signal. With such an arrangement, it is enabled to enhance response and stability of air-fuel ratio control through learning control method. |
