Abstract: A method controls an exhaust gas temperature from a vehicle engine during regeneration of particulate filter (PF) in a vehicle having an oxidation catalyst (OC) and a selective catalytic reduction catalyst (SCR). The method ensures that a final OC temperature does not exceed a maximum of the target OC outlet temperature and a calibrated maximum OC outlet temperature. An apparatus for controlling a temperature of the exhaust gas includes sensors for measuring a temperature within the exhaust system and a controller having an algorithm, an OC temperature lookup table, and a PF temperature lookup table. The algorithm calculates a target OC outlet temperature using the lookup tables and a delayed error value that compensates for a thermal mass of the SCR. Actual OC outlet temperature is limited during regeneration of the PF to the lesser of the target OC outlet temperature and a calibrated maximum OC outlet temperature.
