    Abstract: A coolant control system of a vehicle includes an adjusting module that: (i) receives an engine output coolant temperature measured at a coolant output of an internal combustion engine; (ii) adjusts the engine output coolant temperature based on a reference temperature to produce a first adjusted coolant temperature; (iii) receives an engine input coolant temperature measured at a coolant input of the internal combustion engine; and (iv) adjusts the engine input coolant temperature based on the reference temperature to produce a second adjusted coolant temperature. The coolant control system also includes a difference module that determines a difference between the first and second adjusted coolant temperatures. The coolant control system also includes a pump control module that controls a coolant output of a coolant pump based on the difference between the first and second adjusted coolant temperatures.

    Abstract: A coolant control system of a vehicle includes a pump control module and a coolant valve control module. The pump control module selectively activates a coolant pump. The coolant pump pumps coolant into coolant channels formed in an integrated exhaust manifold (IEM) of an engine. The coolant valve control module selectively actuates a coolant valve that controls coolant flow from the coolant channels formed in the IEM to a transmission heat exchanger based on a first temperature of a transmission and a second temperature of coolant within the integrated exhaust manifold of the engine.

    Abstract: A coolant control system of a vehicle includes a fraction module, and a coolant valve control module. The fraction module determines an oil fuel fraction based on an amount of fuel in an amount of engine oil. The coolant valve control module, based on the oil fuel fraction, selectively actuates a coolant valve to enable coolant flow from an integrated exhaust manifold (IEM) of an engine to an engine oil heat exchanger.

    Abstract: A system includes a coolant management module that, determines whether an engine of a vehicle is off, determines, in response to a determination that the engine is off, whether a heater associated with the engine is on, receives one of a plurality of engine coolant temperature (ECT) measurements and a respective location associated with the received ECT measurement, and communicates the respective location and an instruction to direct engine coolant flow from the respective location to one of the heater and engine. The system also includes a coolant control module that selectively actuates one or more coolant control valves based on the respective location and the instruction.

    Abstract: A system including a target module determining a target temperature of coolant at an input of an engine for a maximum amount of fuel efficiency. A mode module disables closed loop control based on temperatures of coolant entering the engine and at an output of a radiator. An open loop module determines first and second temperatures of coolant at inputs of a coolant control valve that receive coolant from the radiator and a channel that bypasses the radiator. A ratio module determines a ratio based on the first and second temperatures and the temperatures of the coolant entering the engine and at the radiator output. A closed loop module generates a correction value based on the target temperature and the temperature of the coolant entering the engine. A position module adjusts the coolant control valve based on the ratio, the correction value and whether closed loop control is disabled.
