Patent ID: 8392091

Claim:
Method for managing an exhaust aftertreatment system within a vehicle comprising a catalyst device, the method comprising: monitoring a digital map device providing a predicted vehicle operating condition through a travel route; determining a predicted exhaust gas temperature profile based upon said monitoring said digital map device; and controlling operation of said aftertreatment system based upon said predicted exhaust gas temperature profile, said controlling comprising one of scheduling ammonia generation in said aftertreatment system based upon predicting conditions enabling ammonia production based upon said predicted exhaust gas temperature profile, controlling a hybrid powertrain based upon said predicted exhaust gas temperature profile to facilitate said operation of said aftertreatment system, controlling said hybrid powertrain comprising one of scheduling operation under battery power and fuel power such that fueled operation is scheduled to facilitate catalyst regeneration and scheduling operation of an electric machine of said hybrid powertrain to achieve engine operation facilitating said operation of said aftertreatment system, scheduling operation in a first homogeneous charge compression ignition combustion mode and operation in a second combustion mode to facilitate said operation of said aftertreatment system based upon said predicted exhaust gas temperature profile, and scheduling operation of a bypass valve to protect a temperature sensitive device of said aftertreatment system based upon said predicted exhaust gas temperature profile.
