Title: Air-fuel ratio control device having learning function
Inventor: ISHIDA KATSUMI
IPC: F02D41/14
Filed: 1989-12-27
Abstract: PURPOSE:To reduce the amount of calculating by obtaining the mean value of deviations from a reference value of a feedback control factor each time the discriminated result by means of a fuel excess/deficiency discriminating means is reversed even times, for renewing learning values. CONSTITUTION:In response to the operating conditions of an engine, a calculating means 8 obtains required fuel quantities, which are corrected by a correcting means 12 using learning values stored in a storing means 10, and the supply fuel quantity is feedback-controlled by a means 14 in response to the excess or deficiency of fuel through an air-fuel ratio sensor 2 and a discriminating means 20. And, each time the discriminated results of the discriminating means 20 are reversed even times, a calculating means 16 obtains the mean value of deviations from the reference value of a control factor through a feedback control means 14 at the time of reversal, and on the basis of this, a renewing means 18 renew the learning values in the storing means 10. Thus, with a small amount of calculation, the learning values can be renewed while properly reflecting the mean value trend of the feedback control factor, and an accurate air-fuel ratio feedback control can be enabled.
