In one example, a method for a controller of a vehicle comprises adjusting an operating parameter of the vehicle in response to a margin between a moving average tailpipe NOx emissions and a threshold tailpipe NOx emissions decreasing below a threshold NOx emissions margin, the moving average tailpipe NOx emissions calculated at regular intervals over a plurality of overlapping moving average windows (MAWs) of measured tailpipe NOx emissions. The threshold tailpipe NOx margin may be predicted based on expected engine-out NOx emissions of the vehicle, current NOx emissions sensitivities, and/or a predicted catalyst conversion efficiency in relation to the expected engine-out NOx emissions.",
