1. An exhaust control system for a vehicle, comprising:
- an exhaust system modeling module that 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 said vehicle, wherein exhaust gas flows through said exhaust system component; and
an actuator control module that selectively adjusts an engine operating parameter based on at least one of said input gas temperature, said output gas temperature, said mass temperature, and said pressure.

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.
