Abstract: Systems and methods for operating an engine that includes a compression ratio linkage for adjusting engine compression ratio are described. The systems and methods provide different ways of changing a compression ratio of an engine based on forecast or anticipated engine operating conditions. In one example, the forecast or anticipated engine operating conditions may include a forecast or anticipated transmission gear shift.

Abstract: Embodiments for diagnosing a humidity sensor are provided. One example method comprises, responsive to a humidity sensor test cycle, pumping air conditioning and windshield washer gas flows past a humidity sensor, and indicating humidity sensor degradation based on a response of the humidity sensor to the air conditioning and windshield washer gas flows. In this way, degradation of the humidity sensor may be indicated if the humidity sensed by the humidity sensor does not change responsive to the humidity sensor test cycle being initiated.

Abstract: Methods and systems are provided for estimating exhaust gas recirculation (EGR) flow based on outputs of two different intake oxygen sensors arranged in an engine intake system. In one example, a method may include, when the engine is boosted, adjusting exhaust gas recirculation (EGR) based on a first output of a first oxygen sensor positioned in an intake passage and exposed to EGR gases and a second output of a second oxygen sensor not exposed to EGR gases and exposed to positive crankcase ventilation and purge flow gases. For example, EGR flow may be estimated based on a difference between the first output and the second output.

Abstract: Methods and systems are provided for accurately learning the zero point of an intake gas oxygen sensor during selected engine no-fueling conditions. The learned zero point is used to infer EGR flow and accordingly adjust EGR valve control. In addition, EGR valve leakage is diagnosed based on the zero point learned during a DFSO adaptation relative to a zero point learned during an idle adaptation.

Abstract: Methods and systems are provided for accurately learning the zero point of an intake gas oxygen sensor in varying ambient humidity conditions. The learned zero point is corrected based on an estimated ambient humidity to calibrate the reading for dry air conditions or standard humidity conditions. EGR control is performed by comparing the output of an intake oxygen sensor during EGR conditions relative to the humidity-corrected zero point.

Abstract: Methods and systems are provided for reducing EGR estimation errors during lean engine operating conditions. During lean engine operation, EGR is disabled if the estimated exhaust air-fuel ratio becomes leaner than a lean threshold. The lean threshold is adjusted based on an upper limit of EGR errors that may be tolerated by the engine at a given engine speed and load.

Abstract: Methods and systems are provided for correcting an EGR rate determined based on an intake manifold oxygen sensor based on an air-fuel ratio of EGR. The output of the sensor is corrected to compensate for extra fuel in rich EGR or extra air in lean EGR and used to reliably estimate the EGR rate. One or more engine operating parameters are adjusted based on an uncorrected output of the sensor.
