METHOD AMD SYSTEM OF DETERMINING SUITABILITY OF CORRECTION TO CONTROL LOGIC OF SELECTIVE CATALYTIC REDUCTION CATALYST

摘要

The present invention relates to a method and apparatus for determining the suitability of a control logic of a selective reduction catalyst which can ensure the reliability of the correction performed in the control logic that controls the operation of the selective reduction catalyst. A method of determining a suitability of a control logic of a selective reduction catalyst according to an embodiment of the present invention includes calculating a suitability function of correction based on a previous error and a current error when the correction is performed; Calculating a fitness coefficient based on the correction fitness; Determining whether correction is appropriate based on the number of times of correction and the number of times of matching; And resetting the control logic if correction is not appropriate.
