Method and system for adapting a clean filter correction map for a selective catalyst reduction filter

A system for adapting the clean filter correction map for a selective catalyst reduction filter of an exhaust gas aftertreatment system in fluid communication with an engine of a vehicle, the system comprising:

• a first pressure sensor at an inlet side of the selective catalytic reduction filter between the selective catalytic reduction filter and the engine;
• a second pressure disposed at an outlet side of the selective catalytic reduction filter;
• a differential pressure module in communication with the first pressure sensor and the second pressure sensor and configured to generate a delta pressure signal corresponding to a pressure drop between the first pressure sensor and the second pressure sensor;
• and
• a controller configured to:
• determine a number of completed regeneration events of the selective catalytic reduction filter;
• compare the number of completed regeneration events to an evaluation element, wherein the evaluation element is a predetermined discrete number of regeneration events;
• enable an adaptation module by executing one of a first control action when the number of completed regeneration events is less than the evaluation element, a second control action when the number of completed regeneration events is equal to the evaluation element, and a third control action when the number of completed regeneration events is greater than the evaluation element.
