Abstract: Disclosed herein are devices, systems, and methods relating to balancing engine performance and engine emissions of an engine in a vehicle in real time. In an example, a method can include sensing operation data indicative of an engine response during a current engine operation. The current ending operation can include a supervisory control of engine emissions. The method can include evaluating a response model to determine engine performance deviation data corresponding to an expected baseline engine performance and an expected current engine performance at the current engine operation. This evaluation can be performed via controller. This evaluation can be based on the operation data. The method can include generating and setting a performance constraint in response to evaluating the response model. The performance constraint can be set such that the engine performance deviation data is maintained at a controls objective that inhibits deterioration of the engine performance over time.
