Abstract: A system includes an internal combustion engine providing exhaust gases to an exhaust conduit, an aftertreatment system having an SCR catalyst component and disposed in the exhaust conduit. The system further includes a first NH3 sensing element preferentially sensitive to NH3 and a second NH3 sensing element preferentially sensitive to NO2 in the exhaust conduit. Both NH3 sensing elements are positioned downstream of the SCR catalyst component. The system includes a controller having a test conditions module that determines whether an NO2 concentration downstream of the SCR catalyst component is below a threshold value, an NH3 diagnostic module that provides a detection comparison value in response to the NO2 concentration, a first signal from the first NH3 sensing element, and a second signal from the second NH3 sensing element. The controller includes a sensor condition module that provides an NH3 sensor condition value in response to the detection comparison value.

Abstract: Systems and apparatuses include a vehicle locator circuit that is structured to receive GPS signal coordinates and a road parameter associated with the GPS signal coordinates. The vehicle locator circuit is further structured to identify a current road segment associated with the GPS coordinates. A map data circuit is structured to store the road parameter and GPS signal coordinates associated with the current road segment. A route response circuit is structured to determine look-ahead parameters characterizing a future road segment based on input received from the vehicle locator circuit and the map data circuit, and a communication interface is structured to communicate the look-ahead parameters to an engine control module for improving vehicle performance during travel on the future road segment.

Abstract: An example method includes interpreting an NH3 composition value at a position upstream of a selective reduction catalyst (SCR) element fluidly disposed in the exhaust conduit of an engine, interpreting a NOx composition value at a position downstream of the SCR element, and determining an NH3 sensor rationality threshold in response to the upstream NH3 composition value. The method further includes determining an NH3 sensor health value as indicating a sensor failure in response to the downstream NOx composition value exceeding the NH3 sensor rationality threshold.

Abstract: A vehicle comprises an aftertreatment system configured to reduce constituents of an exhaust gas. The vehicle also includes a controller configured to determine a predicted load on the vehicle during a route, and adjust at least one of a temperature of the aftertreatment system or an amount of a reductant inserted into the aftertreatment system based on the predicted load.

Abstract: A system and method are disclosed for a selective catalytic reductant (SCR) catalyst with an NH3 sensor operationally coupled mid-catalyst of the SCR catalyst and a controller in electronic communication with the NH3 sensor configured to interpret a diagnostic enablement condition of the NH3 sensor. The controller is configured to control a reductant injector to inject varying reductant amounts over a range of ANR values in response to the enablement condition being satisfied. The controller also is configured to determine a lower bound of estimates of the NH3 amount at the mid-bed catalyst position for the reductant amounts, and determine an NH3 sensor fault condition in response to actual sensor outputs and the NH3 lower bound value.
