Method and system for adapting a clean filter correction map for a selective catalyst reduction filter
Abstract:
A system and method for adapting the clean filter correction map for a selective catalyst reduction filter SCRF of an exhaust gas aftertreatment system are provided. The system may be in fluid communication with an engine of a vehicle. The system may include a first pressure sensor and a second pressure. A differential pressure module is 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. The system may also include a controller configured to determine a number of completed regeneration events of the SCRF; compare the number of completed regeneration events to an evaluation element; and enable an adaptation module by executing one of a first control action, a second control action, and a third control action.
