Abstract
A method of defining a target regeneration temperature setpoint for exhaust gas upstream of a particulate filter of an exhaust gas treatment system includes as defining the regeneration temperature setpoint to include an idle temperature setpoint when the current vehicle operating mode is classified as an idle mode, and defining the regeneration temperature setpoint to include a driving temperature setpoint when the current vehicle operating mode is classified as a driving mode. The idle temperature setpoint and the driving temperature setpoint are derived individually of and separately from each other, and are based on different criteria.
