Systems and methods for providing an improved strategy for controlling a variable speed water pump in a vehicle. In some embodiments, more than one water pump speed function is calculated based on values obtained from vehicle sensors, and a controller chooses among the water pump speed function results to set a water pump speed. In some embodiments, the water pump speed is increased when driveline torque is greater than a threshold amount for an amount of time that varies based on the driveline torque. In some embodiments, ambient temperature is considered while determining whether the water pump should provide full coolant flow to an auxiliary coolant loop of a trailer.

Methods and systems are provided for a cooling module assembly for a vehicle. In one example, the cooling module assembly includes a first set of fins configured to flow a first fluid through a first sinusoidal, continuous inner passage, and a second set of fins configured to flow a second fluid through a second sinusoidal, continuous inner passage. The second set of fins shares a common plane with the first set of fins and together forms a semi-circular structure.

An engine and cabin thermal management system for use with a vehicle having an engine, a cabin heating system configured to thermally heat a cabin of the vehicle, a coolant system operably coupled to the engine and to the cabin heating system to thermally manage a temperature of the engine and a temperature of the cabin. The coolant system having one or more coolant thermal storage units fluidly coupled with a radiator and heater core of the coolant system forming a coolant loop. The system further having a control system configured to monitor and maintain at least a predetermined coolant temperature at the cabin heating system even during a coolant temperature decrease at the engine stops.

An engine controller includes a reading section and a ratio-setting control section. The reading section is included in an air conditioner. The air conditioner draws an air into an air-conditioner housing, heats the air by a cooling water cooling the engine, and blows the air into a vehicle compartment. The reading section reads a state information that relates to a state of the air conditioner having an effect on an outside-air drawing ratio. The outside-air drawing ratio is a ratio of a volume of an outside air to a total volume of the outside air and an inside air. The ratio-setting control section decreases an amount of heat generated by the engine when the outside-air drawing ratio is a second ratio, which is smaller than a first ratio, to be smaller than an amount of heat generated by the engine when the outside-air drawing ratio is the first ratio.

Methods and systems are provided for expediting engine cooling while reducing the overall energy consumption of the engine cooling system's components. A first circulation pump is used to pump coolant through an engine block as a function of engine output while a second radiator pump is selectively operated when a thermostat valve is open to pump coolant through a radiator and the engine block to effect the engine coolant temperature. Operation of the second pump is coordinated with the operation of a radiator cooling fan and grille shutters to improve radiator performance.
