Abstract:
1. A control system for an engine of a driven vehicle, comprising: one or more actuators for controlling one or more inputs to an engine; at least one engine emission sensor, each of the at least one engine emission sensors for sensing an emission parameter, wherein the at least one emissions sensors detect NOx and PM; a controller coupled to the one or more actuators and the at least one engine emission sensor, the controller including a multi-parameter model that models the effects of changes in the one or more actuators on each of two or more engine operating parameters based on the sensed emission parameters while the vehicle is being driven by a user; and wherein the controller is configured to adjust at least one actuator of the engine and make a change to one or more inputs to the engine in order to produce a controlled change in each of the two or more engine operating parameters as modeled by the multi-parameter model while the vehicle is being driven by a user.
