METHOD AND APPARATUS TO CONTROL ENGINE TEMPERATURE FOR A HYBRID POWERTRAIN

摘要

An internal combustion engine is connected to a transmission to transmit tractive power to a driveline. Engine coolant temperature is determined, and power output of the engine is adjusted based upon the coolant temperature and preferred coolant temperature range. The 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.
