Beschreibung
Zusammenfassung:	The present invention relates to an exhaust temperature and pressure modeling system and a method thereof. An exhaust control system used for vehicle comprises an exhaust system modeling module and an actuator control module. The exhaust system modeling module estimates the input gas temperature, output gas temperature, block temperature and pressure of an exhaust system component of the exhaust system adopted in the vehicle. The exhaust flows through the exhaust system component. The actuator control module selectively adjusts the operation parameter of engine based on at least one selected from input gas temperature, output gas temperature, block temperature and pressure.
