A vehicle thermal management system includes an engine, a coolant pump, a first heat exchanger, a first valve in communication with the first heat exchanger, a second valve having a plurality of outlets, a second heat exchanger in communication with a first of the plurality of outlets, a third heat exchanger in communication with a second of the plurality of outlets, a bypass fluid conduit in communication with a third of the plurality of outlets, and a controller that determines a first potential benefit based upon a loss function of the second heat exchanger, determines a second potential benefit based upon a loss function of the third heat exchanger, compares the first potential to the second potential, and proportionally distributes flow between the first heat exchanger, the second heat exchanger, the third heat exchanger, and the bypass fluid conduit based upon the comparison.
A thermal management system for a vehicle, the system comprising:
A method for controlling a thermal management system in a vehicle that includes an engine producing heat energy and having a coolant inlet and a plurality of coolant outlets, a coolant pump having an outlet in communication with the engine coolant inlet, a radiator having a coolant inlet and a coolant outlet, wherein the radiator exchanges heat between the coolant and an atmosphere surrounding the radiator, a first valve having a coolant inlet in communication with the coolant outlet of the radiator and having a coolant outlet in fluid communication with the coolant pump and operable to control a flow of coolant through the radiator, a second valve having a plurality of coolant inlets each in communication with one of the plurality of engine coolant outlets and having a coolant outlet, a third valve having a coolant inlet in communication with the coolant outlet of the second valve and having a plurality of valve coolant outlets, a cabin heater core having a coolant inlet in communication with a first of the plurality of valve coolant outlets of the third valve and a coolant outlet in communication with the pump coolant inlet, one of an engine oil heat exchanger and a transmission fluid heat exchanger having a coolant inlet in communication with a second of the plurality of valve coolant outlets of the third valve and a coolant outlet in communication with the pump coolant inlet, and a bypass fluid conduit having a coolant inlet in communication with a third of the plurality of valve coolant outlets of the third valve and a coolant outlet in communication with the pump coolant inlet, the method comprising:
