Abstract
A temperature control system comprises a temperature determination module, a temperature correction module, a temperature control module, and an updating module. The temperature determination module determines a desired outlet temperature for an oxidation catalyst (OC) that is located upstream of a particulate filter (PF) in an exhaust system. The temperature correction module determines a temperature correction from a plurality of temperature corrections. The temperature control module controls an outlet temperature of the OC based on the desired outlet temperature and the temperature correction. The updating module selectively updates at least one of the plurality of temperature corrections when an engine speed and an engine load are within respective predetermined ranges.
