摘要： A system and method for engine control and diagnostics are described. The engine system may include an engine having a catalyst in the exhaust system, the exhaust system further having an exhaust gas oxygen sensor upstream of the catalyst and downstream of the catalyst. In one example, the method may include during a first operating mode in which catalyst diagnostics are not carried out, adjusting air-fuel ratio based on both the upstream and downstream exhaust gas oxygen sensors, where air-fuel ratio adjustment responsiveness to the downstream sensor is reduced as the catalyst performance degrades; and during a second operating mode that includes catalyst diagnostics, adjusting air-fuel ratio based on at least the downstream exhaust gas oxygen sensor, where said air-fuel ratio adjustment responsiveness to the downstream sensor is temporarily increased from said reduction generated during the first operating mode.

摘要： Embodiments for predicting catalyst function are disclosed. One example embodiment includes applying a set of parameter readings for a given sample to a support vector machine to generate a classification output, recording a plurality of classification outputs for a plurality of successive samples over a first duration, and indicating catalyst degradation if a threshold percentage of the classification outputs indicates degraded catalyst performance. In this way, catalyst degradation may be indicated using a simplified model that does not require extensive calibration.

摘要： Methods and systems are provided for an engine including a humidity sensor. Degradation of the humidity sensor may be determined based on a change in intake air relative humidity as compared to a change in intake air temperature or pressure, under selected conditions. An amount of exhaust gas recirculated to an engine intake is adjusted differently based on whether the humidity sensor is degraded or functional.
