Abstract
An apparatus, system, and method are disclosed for determining the distribution of particulate matter on a particulate filter. The apparatus, in one embodiment, determines a first distribution of particulate matter by comparing the pressure change across the particulate filter with a change in engine operating conditions. The apparatus may include an input module for receiving input corresponding to engine operating conditions and input from a differential pressure sensor and a feedback module to determine a first distribution of particulate matter. The apparatus may further include a feed forward module for determining a particulate distribution trend and a selection control module to combine the first distribution of particulate matter with the particulate distribution trend to determine a second distribution of particulate matter. The distribution may be defined as a uniform distribution factor in certain embodiments.
