Abstract
A vehicle system includes an electric motor, an internal combustion engine, and a heating system configured to transfer heat from the internal combustion engine to a passenger compartment of the vehicle. The system includes a controller configured to operate the electric motor and the internal combustion engine according to one of a plurality of drive cycle profiles. The controller selects the drive cycle profile based on an ambient temperature. The drive cycle profiles include a first drive cycle profile that commands power from the electric motor until the battery system reaches a predetermined state of charge and subsequently commands power from the internal combustion engine and a second drive cycle profile that commands power from the internal combustion engine and subsequently commands power from the electric motor.
