Abstract: A method for managing thermal energy of a vehicle having a battery and an electric propulsion system is provided. The system monitors a current battery temperature, after the vehicle is connected to an outside power source at a plug time, and determines an outside air temperature. The system predicts a cabin heating temperature for a subsequent drive cycle. The subsequent drive cycle occurs when the vehicle is no longer connected to the outside power source. If the predicted cabin heating temperature is greater than the outside air temperature, the system heats the battery to a thermal storage temperature that is greater than a target operating temperature of the battery. Therefore, thermal energy is stored within the battery, and may be transferred to heat the cabin.

Abstract: A vehicle propulsion system includes an engine having a coolant inlet and a coolant outlet, a coolant pump having an outlet in communication with the engine coolant inlet, a pressure sensor in fluid communication with the engine coolant outlet and that generates a pressure signal indicative of a pressure in the engine coolant outlet, and a controller in communication with the pressure sensor and the coolant pump. The controller is programmed to control a flow of coolant through the engine from the coolant pump based upon the pressure signal.

Abstract: An automobile vehicle exhaust gas heat recovery system includes an engine having a turbocharger. A cooling pump provides coolant flow to the engine and the turbocharger. A combined coolant discharge header receives coolant discharged from the engine and the turbocharger. A main rotary valve receives coolant discharged from the combined coolant discharge header. The main rotary valve includes multiple rotary valves selectively distributing all of the coolant in the combined coolant discharge header to at least one of an engine heater, a heater core and a transmission oil heater during a cold start operation. An exhaust gas heat recovery (EGHR) device is positioned to receive the coolant discharged from any one, any two or all of the engine heater, the heater core and the transmission oil heater and in a path to return the coolant to the cooling pump during the cold start operation of the engine.

Abstract: A system including startup, load, flow, and peak estimation modules. The startup module, during a startup period or in response to a startup of the engine, receives a temperature signal and generates a first condition signal. The load module determines a load on the engine and generates a second condition signal. The flow module, if the first condition signal indicates a temperature of the engine is less than a first predetermined temperature and if the second condition signal indicates the load is less than a predetermined threshold, operates a pump to circulate coolant during the startup period. The peak estimation module estimates a temperature of a hottest metal location on the engine. The flow module increases a speed of the pump if the temperature of the hottest metal location is greater than a second predetermined temperature or the load is greater than or equal to the predetermined threshold.

Abstract: Disclosed are two-valve, split-layout engine cooling systems, methods for making and method for operating such cooling systems, engine coolant valve assembly configurations, and vehicles equipped with an active thermal management system for cooling select powertrain components. A disclosed thermal management system includes a radiator for cooling coolant fluid, and a coolant pump for circulating coolant fluid received from the radiator. A set of conduits fluidly connect the coolant pump to an engine block, a cylinder head, and an exhaust manifold. Another set of conduits fluidly connect the engine block, cylinder head, and exhaust manifold to the radiator, coolant pump, and one or more oil heaters. A first valve assembly is operable to regulate coolant flow between the coolant pump and the radiator. A second valve assembly is operable to regulate coolant fluid flow, individually and jointly, between the engine block, cylinder head, exhaust manifold, radiator, coolant pump, and oil heater(s).

Abstract: A system according to the principles of the present disclosure includes a transmission fluid temperature sensor and a coolant valve control module. The transmission fluid temperature sensor measures a temperature of transmission fluid that is circulated through a transmission. The coolant valve control module controls at least one coolant valve to adjust coolant flow from an engine to a transmission fluid heat exchanger and at least one of a radiator, an engine oil heat exchanger, and a heater core. When the transmission fluid temperature is less than a first temperature, the coolant valve control module controls the at least one coolant valve to allow coolant flow from the engine to the transmission fluid heat exchanger and prevent coolant flow from the engine to the at least one of the radiator, the engine oil heat exchanger, and the heater core.

Abstract: A strategy for controlling an electric pump and control valve in an internal combustion engine cooling system compensates for backpressure variations and maintains system operation within design parameters. The method comprises the steps of measuring the coolant temperature, measuring the electrical current and voltage to the pump motor, determining the pump speed and coolant flow, determining the desired coolant flow, determining a negative correction to the flow control valve and pump if desired flow is less than present coolant flow and determining a positive correction to the flow control valve and pump if desired flow is more than present coolant flow and undertaking this correction to coolant flow. Thus, based upon inferred back pressure in the engine coolant system from the data relating to the pump energy input, proper coolant flow, heat rejection and engine operating temperature can be maintained in spite of variations in system flow restrictions and backpressure.
