Abstract
An exhaust control system for a vehicle comprises an exhaust system modeling module and an actuator control module. The exhaust system modeling module estimates an input gas temperature, an output gas temperature, a mass temperature, and a pressure for an exhaust system component of an exhaust system implemented in the vehicle. Exhaust gas flows through the exhaust system component. The actuator control module selectively adjusts an engine operating parameter based on at least one of the input gas temperature, the output gas temperature, the mass temperature, and the pressure.
