Abstract
A vehicle powertrain thermal management system for distributing thermal energy to vehicle powertrain components, including an engine and a transmission. The system for managing heat energy includes a coolant pump, a first control valve, a second control valve, a radiator, a heater core, and a transmission oil heat exchanger. The first control valve has an inlet that is in fluid communication with the engine coolant outlet. The first control valve also has a first control valve outlet. The second control valve has a first inlet, a second inlet, a first outlet, a second outlet and a third outlet. Heat energy produced by the engine is transferred to the radiator through control of the first control valve and to at least one of the heater core, and the transmission oil heat exchanger through the control of the second control valve.
