Abstract
Methods and systems are provided for converting an asymmetric sensor response of an exhaust gas sensor to a symmetric response. In one example, a method includes adjusting fuel injection responsive to a modified exhaust oxygen feedback signal from an exhaust gas sensor, where the modified exhaust oxygen feedback signal is modified by transforming an asymmetric response of the exhaust gas sensor to a symmetric response. Further, the method may include adapting parameters of an anticipatory controller of the exhaust gas sensor based on the modified symmetric response.
