Abstract: Methods and systems provided for determining a phase state and/or for determining a degree of subcooling in a fluid. An exemplary method for operating a refrigeration cycle includes flowing a refrigerant through a metering device and calculating a pressure differential of the refrigerant across the metering device. Further, the method includes determining whether the refrigerant is a saturated liquid based on the pressure differential. The method includes, when the refrigerant is not a saturated liquid, cooling the refrigerant upstream of the metering device.

Abstract: Systems and methods are provided for determining a temperature of a thermal system that includes fluid conduits. A sensor monitors a current state of the temperature. A controller receives a signal from the sensor that is representative of the current state; determines a flow in the fluid conduits; determines a noise covariance of the thermal system; processes a thermal model of the thermal system; predicts a next-step state of the parameter at a time after the current state; and corrects the next-step state based, at least in-part, on the noise covariance resulting in a corrected next-step state.

Abstract: Technical methods described herein include an emissions control system for treating exhaust gas from an internal combustion engine in a motor vehicle. The emissions control system includes a three-reaction oxygen storage model. The system further includes a three-way catalyst and a controller that controls an oxygen storage level for the three-way catalyst. The controller determines a first reaction rate representing a net rate of cerium oxidation by oxygen, a second reaction rate representing a net rate of cerium reduction by carbon monoxide, and a third reaction rate representing a net rate of cerium reduction by hydrogen. The controller further determines the oxygen storage level based on the first reaction rate, the second reaction rate, and the third reaction rate.

Abstract: An exhaust aftertreatment system including a selective catalytic reduction device (SCR), a NOx sensor and a reductant injection system is described. A method for controlling the reductant injection system to inject reductant into the exhaust gas feedstream upstream relative to the SCR includes monitoring engine operation, and determining an initial reductant dosing rate responsive to the engine operation. A dosing perturbation is induced in the reductant dosing rate. The exhaust gas feedstream is monitored via the NOx sensor, and a reductant dosing correction term is determined based upon the monitoring. A final dosing rate for controlling the reductant injection system is determined based upon the initial reductant dosing rate, the dosing perturbation, and the reductant dosing correction term.

Abstract: A method of estimating a mass flow rate of nitrogen oxides in exhaust gas includes sensing a mass flow rate of a flow of exhaust gas from the engine. A nitrogen oxides base concentration for when the engine is operating at a reference state is defined, and a nitrogen oxides ratio for a current operating state of the internal combustion engine is calculated. The mass flow rate of the flow of exhaust gas, the nitrogen oxides base concentration, and the nitrogen oxides ratio for the current operating state of the engine are multiplied together to define an estimated value of the current mass flow rate of nitrogen oxides in the flow of exhaust gas from the engine. The estimated value of the mass flow rate of nitrogen oxides may be compared to the output from a nitrogen oxides sensor to determine proper functionality of the nitrogen oxides sensor.

Abstract: An exhaust treatment system to treat exhaust gas includes a particulate filter configured to trap soot contained in the exhaust gas, and a pressure sensor that outputs a pressure signal indicative of a pressure differential of the particulate filter. A soot mass module is configured to determine a soot mass indicative of an amount of soot stored in the particulate filter based on the pressure differential. The soot mass is selectively determined according to a first soot model or a second soot model. An adaptation soot load module corrects the first soot model based on the second soot model such that the first soot model is adapted to the second soot model. A frequency regeneration module determines an actual rate at which the first soot model is corrected. The frequency regeneration module further determines the particulate filter is excessively regenerated based on the actual rate and a threshold.
