1. A method for heat coordination, comprising:
operating a propulsion system that generates heat as wasted power, wherein operating the propulsion system includes operating an internal combustion engine and operating an electric machine both configured to provide output torque for propulsion;
operating a device utilizing the heat generated by the propulsion system;
operating a heat transfer system configured for transferring the heat generated by the propulsion system from the propulsion system to the device;
within a computerized processor,
determining a minimum useful waste thermal power to operate the device with a heat coordination model;
monitoring a desired output torque for the propulsion system based on a driver request; and
utilizing a cost-based determination to determine a propulsion system operating point based upon the desired output torque and the minimum useful waste thermal power to operate the device, wherein determining the propulsion system operating point includes determining an operating point for the internal combustion engine and determining an operating point for the electric machine; and
utilizing the propulsion system operating point to control the propulsion system; wherein operating the heat transfer system includes directing a flow of coolant through the internal combustion engine and the electric machine for transferring the heat to the device.
