摘要
An engine air/fuel control system is disclosed having one feedback correction loop generating a feedback variable by essentially integrating the output of an exhaust gas oxygen sensor. A second feedback loop adaptively learns a feedback correction from the difference between the feedback variable and its desired value such as unity. A range of authority for the total air/fuel controller is adaptively learned from the learned correction value to maximize the correction which may be applied by the feedback variable under all operating conditions.
