Abstract: A vehicle, system, and method of warming the transmission fluid with a thermoelectric generator is also provided. Disclosed is vehicle having an internal combustion engine, a transmission containing a transmission fluid, a coolant circuit configured to remove heat from the engine, and a thermoelectric generator. The thermoelectric generator is in non-contact thermal communication with the hot exhaust gas produced by the engine and the relatively cooler coolant circulating through the coolant circuit. The thermoelectric generator produces a current from the temperature gradient between the exhaust gas relative and coolant and transfers heat from the exhaust gas to the coolant. The heat coolant is conveyed to a transmission heat exchanger to heat the transmission fluid. A heating element is disposed in thermal contact with the transmission fluid and the heating element is powered by the electric current produced by the thermoelectric generator.

Abstract: A vehicle thermal management system includes a radiator receiving a liquid coolant in a coolant supply line and discharging the coolant into a coolant pump supply line. A coolant pump receives the coolant from the coolant pump supply line and discharges the coolant into multiple engine components. A transmission oil heat exchanger defining a first transmission oil heat exchanger receives the coolant after being discharged from the multiple engine components. An air-to-coolant sub-cooling heat exchanger defines a second transmission oil heat exchanger. The sub-cooling heat exchanger receives a portion of the coolant bypassing the multiple engine components.

Abstract: 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.
