Abstract
A method for managing an exhaust aftertreatment system within a vehicle including a catalyst device includes monitoring a digital map device providing a predicted vehicle operating condition through a travel route, and determining a predicted exhaust gas temperature profile based upon the monitoring of the digital map device. Operation of the catalyst device is controlled based upon the predicted exhaust gas temperature profile.
