More Information
Summary:An internal combustion engine is fluidly connected to an exhaust aftertreatment system and operatively connected to an electro-mechanical transmission to transmit tractive power to a driveline. The engine is controlled during an engine operating cycle by determining a temperature of the exhaust aftertreatment system and adjusting power output of the engine based upon the temperature of the exhaust aftertreatment system and a preferred temperature range of the exhaust aftertreatment system. The electro-mechanical transmission is controlled to transmit tractive power to the driveline to meet an operator torque request based upon the adjusted power output of the engine.
