| description | Systems and methods for updating the PF soot load of an engine are provided herein. In one embodiment, the method may include performing regeneration in response to both pressure-based measurements as well as estimated soot loading independent of the pressure-based measurements, where during conditions in which the pressure-based measurements may be inaccurate, the soot load is estimated based on operating conditions and previous pressure-based measurements that occurred during previous conditions in which the pressure-based measurements are more accurate. In this way, more continuous monitoring of particulate filter loading is provided, while taking advantage of pressure-based measurements from the most recent accurate reading, for example, and operating conditions that have transpired since such reading, including transient conditions. Thus, more appropriately timed regeneration may be provided. |
