Abstract (en)
[origin: US2018112613A1] A method for operating a drive device with a drive unit and an exhaust gas purification device. The gas exhaust purification device is provided with a catalytic converter through which an exhaust gas stream can flow, as well as with a first lambda sensor arranged upstream of the catalytic converter in the exhaust gas stream and with a second lambda sensor arranged downstream of the catalytic converter in the exhaust gas stream, wherein an oxygen filling value of an oxygen storage device of the catalytic converter is determined on the basis of a first lambda signal provided by the first lambda signal sensor as well as an offset value.
