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.

11. A method for operating a vehicle with an electric motor that provides power to the vehicle with energy from the battery system, an internal combustion engine, and a heating system that transfers heat from the internal combustion engine to a passenger compartment of the vehicle, the method comprising the steps of:
-
receiving an initial location and an intended destination; generating a trip profile for a trip between the initial location and the intended destination; determining, with an ambient temperature sensor on the vehicle, an ambient temperature receiving, by a controller on the vehicle, the ambient temperature; selecting, by the controller on the vehicle, a drive cycle profile from a plurality of drive cycle profiles based on the trip profile and the ambient temperature, wherein the plurality of drive cycle profiles includes a first drive cycle profile and a second drive cycle profile, wherein the first drive cycle profile 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 wherein the second drive cycle profile commands power from the internal combustion engine and subsequently commands power from the electric motor, wherein the selecting step includes selecting the first drive cycle profile when the ambient temperature is greater than a predetermined temperature and selecting the second drive cycle profile when the ambient temperature is less than or equal to the predetermined temperature; and operating the vehicle according to the selected drive cycle profile. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A heating performance system for a vehicle with an electric motor and an internal combustion engine, the heating performance system comprising:
-
a trip module configured to generate a trip profile for a trip between an initial location and an intended destination; a drive cycle module coupled to the trip module and configured to generate at least a first drive cycle profile and a second drive cycle profile based on the trip profile, wherein the first drive cycle profile commands propulsion power from the internal combustion engine at a first position during the trip profile and the second drive cycle profile commands propulsion power from the internal combustion engine at a second position during the trip profile, earlier than the first position; an ambient temperature sensor configured to determine an ambient temperature; and a controller coupled to the drive cycle module and the ambient temperature sensor and configured to select between the first drive cycle profile and the second drive cycle profile based on the ambient temperature for operation of the vehicle according to the selected drive cycle profile, wherein the controller is configured to select the second drive cycle profile when the ambient temperature is less than a predetermined temperature such that heat from the internal combustion engine is directed into a passenger compartment of the vehicle earlier in the trip profile.
