ABSTRACT:
A method and system is provided for determining non-sensed vehicle operating parameters of a vehicle system. The method and system further provide for determining an engine air mass flow rate using the non-sensed vehicle operating parameters. A plurality of vehicle operating set-points may be determined using the non-sensed vehicle system operating parameters and the non-sensed engine air mass flow rate. A controller may use the vehicle operating set-points in order to control emissions of the vehicle system.
