Abstract: Methods and systems for an engine system including an exhaust gas sensor are disclosed. In one example, under a first engine fueling condition, an air-fuel ratio correction factor is determined based on an expected air-fuel ratio and an actual air-fuel ratio. During a second engine fueling condition and a third engine non-fueling condition, fuel alcohol content and ambient humidity, respectively, are determined based on the exhaust gas sensor and corrected based on the air-fuel ratio correction factor.

Abstract: A fuel cell oxidation reduction reaction catalyst comprising a carbon substrate, an amorphous metal oxide intermediate layer on the substrate, and an intertwined matrix of platinum and elemental niobium arranged to form a surface metal layer covering the intermediate layer such that upon oxidation, the niobium binds with oxygen resulting in strengthened bonds between the platinum and the intermediate layer.

Abstract: Methods and systems are provided for operating an exhaust oxygen sensor coupled to an exhaust passage of an internal combustion engine in response to detecting water at the sensor. In one example, a method may include indicating water at an exhaust oxygen sensor positioned in an engine exhaust passage based on a sensor parameter of the exhaust oxygen sensor while operating the exhaust oxygen sensor in a variable voltage (VVs) mode where a reference voltage is adjusted from a lower, first voltage to a higher, second voltage; and adjusting one or more of sensor operation and engine operation based on the indicating water.

Abstract: Methods and systems are provided for improving operation of a vehicle heating, ventilation, and air conditioning system. In one example, a method may include calibrating a vehicle humidity sensor position inside a cabin of the vehicle by obtaining one or more humidity measurements with one or more personal computing devices positioned inside the cabin, and may further include adjusting operation of the heating, ventilation, and air conditioning system responsive to the calibration. In this way, an interior humidity sensor of a vehicle may be regularly calibrated, which may improve operation of the vehicle heating, ventilation, and air conditioning system, and may further increase fuel economy.

Abstract: Methods and systems are provided for triggering a humidity measurement based on changes in ambient conditions. In one example, a method may include, in response to a higher than threshold change in ambient air temperature or pressure, operating an oxygen sensor to update an ambient humidity estimate. Engine operation parameters may be adjusted based on the updated ambient humidity estimate.

Abstract: Methods and systems are provided for estimating water storage in a charge air cooler (CAC). In one example, an amount of water in charge air exiting the CAC may be based on an output of an oxygen sensor positioned downstream of the CAC. Further, engine actuators may be adjusted to increase combustion stability and/or reduce condensate formation based on the amount of water exiting the CAC.

Abstract: Methods and systems are provided for conducting measurements of relative humidity via the use of either an ultrasonic sensor positioned on the vehicle, or via another sensor. In one example, responsive to a request for a relative humidity measurement and an indication of fueled engine operation, the ultrasonic sensor may be utilized, whereas responsive to an indication of non-fueled engine operation, another sensor may be utilized. In this way, robust measurement of relative humidity with desired accuracy may be actively determined, rather than opportunistically, and such measurements of relative humidity may be utilized to adjust vehicle operating parameters, which may improve overall vehicle operation.

Abstract: A method for an engine may comprise, responsive to a first condition comprising a reference voltage of a first exhaust oxygen sensor operating in variable voltage mode increasing above a threshold voltage, determining a change in an output of the first exhaust oxygen sensor corresponding to the increase in the reference voltage, correcting the output of the first oxygen sensor based on the output change, and adjusting engine operation based on the corrected output. In this way, the accuracy of air-fuel estimates based on the exhaust gas sensor can be preserved, and closed loop fuel control of the engine can be maintained even when the exhaust oxygen sensor is operating VVS mode, thereby reducing engine emissions, increasing fuel economy, and increasing vehicle drivability.
