Abstract: A system is configured to store a relationship data set of a plurality of diagnostic estimators and a plurality of failure modes, each failure mode represents a type of failure that can occur with a sensor or a vehicle component of a vehicle system, each diagnostic estimator is associated with a respective subset of the failure modes, each subset defines a control space within the vehicle system that contains at least one of (i) one or more sensors or (ii) one or more vehicle components. The system is configured to store a healthy diagnostic vector regarding nominal operational parameters of the vehicle system; acquire diagnostic information regarding current operational parameters of the vehicle system to generate an error diagnostic vector; apply the error diagnostic vector to the healthy diagnostic vector to generate a ratio diagnostic vector; and apply the ratio diagnostic vector to generate a value for each failure mode.

Abstract: A system includes a controller configured to store a relationship matrix of a plurality of diagnostic estimators and a plurality of failure modes, each failure mode represents a type of failure that can occur with (i) a sensor or (ii) a vehicle component of a vehicle system, each diagnostic estimator is associated with a respective subset of the failure modes, each respective subset defines a control volume within the vehicle system that contains at least one of (i) one or more sensors or (ii) one or more vehicle components; store a healthy diagnostic vector regarding nominal operational parameters of the vehicle system; acquire diagnostic information regarding current operational parameters of the vehicle system to generate an error diagnostic vector; divide the error diagnostic vector by the healthy diagnostic vector to generate a ratio diagnostic vector; multiply the ratio diagnostic vector with the relationship matrix to generate a value for each failure mode.

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.

Abstract: One exemplary embodiment is a method of operating a system comprising an internal combustion engine system, and an exhaust aftertreatment system comprising an SCR catalyst, and an electronic control system. The method comprises operating the electronic control system to perform the acts of determining a predicted temperature value indicative of a predicted future temperature of the SCR catalyst, determining a temperature profile value using the predicted temperature value and a current temperature value indicative of a current temperature of the SCR catalyst, operating a controller to provide an output indicating a difference between the temperature profile value and a temperature target, determining a heat request using the output of the controller, filtering the heat request using a prediction horizon, and controlling operation of the engine system using the filtered heat request to increase a temperature of the SCR catalyst.
