Abstract: A system includes a processing circuit having a memory coupled to one or more processors, the memory storing instructions therein that, when executed by the one or more processors, cause the one or more processors to: receive an estimated exhaust temperature; generate, based on the estimated exhaust temperature, a forecasted exhaust temperature; modify the forecasted exhaust temperature based on a downpipe model to generate a first temperature profile corresponding to a first component of an exhaust aftertreatment system; and generate, based on the first temperature profile, a second temperature profile corresponding to a second component of the exhaust aftertreatment system.

Abstract: A system includes a processing circuit having a memory coupled to one or more processors, the memory storing instructions therein that, when executed by the one or more processors, cause the one or more processors to: receive engine operational data, the engine operational data indicative of at least one engine operational condition; determine, based on the engine operational data, an estimated exhaust temperature; generate, based on the estimated exhaust temperature and a finite time horizon, a forecasted exhaust temperature; correct the forecasted exhaust temperature based on a downpipe model to generate a first inlet temperature profile corresponding to a first component of the exhaust aftertreatment system; and generate, based on the first inlet temperature profile, a second inlet temperature profile corresponding to a second component of the exhaust aftertreatment system.
