APPARATUS, SYSTEM, AND METHOD FOR DETERMINING AND IMPLEMENTING ESTIMATE RELIABILITY |
摘要 |
<p>An apparatus, system, and method are disclosed for determining the reliability of an estimate such as particulate accumulation on a diesel particulate filter (150), weighing (1232) the estimate according to a function of its reliability, weighing (1234) a prediction of particulate accumulation on the filter according to a function of the estimate's reliability, and combining (1236) the weighted estimate and weighted prediction to determine a combined particulate load estimate (1014b). The degree of reliability can be expressed as a trust factor (1022), and a function of the trust factor (1024) can be used in a low-pass filter of the estimate (1028). The trust factor value (600) depends on filter air flow (610) and particulate distribution (615) in one embodiment. Regeneration of the particulate filter (150) may be initiated (1224) depending on the value of the combined particulate load estimate (1014b).</p> |
