    Abstract: Provided are methods controlling systems including a turbocharger configured to compress air for an engine, a cooler configured to receive turbocharged compressed air, a radiator, a coolant circuit for circulating coolant between the cooler and the radiator and including a bypass to manipulate coolant flow through the cooler. The methods include closing the bypass when engine speed and/or load exceeds a threshold, and otherwise one or more of reducing coolant flow through the cooler when the coolant temperature entering the cooler is higher than the compressed air temperature entering the cooler, manipulating coolant flow through the cooler based on the temperature of the compressed air received by the engine, and reducing coolant flow through the cooler when the temperature of the coolant entering the radiator is less than a temperature of the ambient air. Reducing coolant flow through the cooler reduces the coolant pressure drop within the coolant circuit.

    Abstract: An audio control system of a vehicle includes a sound control module configured to determine N magnitudes for outputting a predetermined engine sound at N frequencies, respectively, where N is an integer greater than one. A magnitude adjustment module is configured to determine at least one N magnitude adjustment values for the N frequencies, respectively, based on at least one of: an intake air temperature; and an exhaust temperature. The sound control module is further configured to determine N adjusted magnitudes for the predetermined engine sound at the N frequencies based on: the N magnitudes for the N frequencies, respectively; and the N magnitude adjustment values for the N frequencies, respectively. An audio driver module is configured to apply power to at least one speaker of the vehicle and output the predetermined engine sound at the N frequencies and the N adjusted magnitudes for the N frequencies, respectively.

    Abstract: A method of controlling a HVAC system of a vehicle includes repeatedly sensing an area of a window of the vehicle that is not covered by frost with a sensor positioned adjacent the window. When the sensed area not covered by frost is less than an area threshold value, a HVAC controller controls the HVAC system to operate in a defrost mode. When the sensed area not covered by frost is equal to or greater than the area threshold value the HVAC controller controls the HVAC system to operate in a cabin heating mode. The HVAC controller automatically switches the HVAC system from the defrost mode to the cabin heating mode when the sensed area not covered by frost increases to a value that is equal to or greater than the area threshold value.

    Abstract: A variable displacement pump for supplying fluid to a system is described. Controlling the variable displacement pump is determined based upon inputs from a fluidic pressure sensor and an accelerometer, and includes determining a desired fluidic pressure and monitoring, via the fluidic pressure sensor, an actual fluidic pressure. A pressure error term is determined based upon a difference between the actual fluidic pressure and the desired fluidic pressure. A time-integrated pressure error term is determined based upon the pressure error term, and a g-force is determined based upon an input signal from the accelerometer. The variable displacement pump is controlled in response to the time-integrated pressure error term when the g-force is greater than a threshold g-force.

    Abstract: A gear pump can be equipped in an engine oil system. The gear pump has a housing, a first gear, and a second gear. The housing has an outlet passage for exiting oil, and has one or more outlet openings for exiting air. The first gear has a set of first teeth with multiple first roots and first tips. The second gear has a set of second teeth with multiple second roots and second tips. The outlet opening(s) is situated in the housing so that it can communicate with a first clearance, with a second clearance, or with both the first and second clearances. The first clearance is established at the confrontation of one of the first roots and one of the second tips. And the second clearance is established at the confrontation of one of the second roots and one of the first tips.
