A method for operating a drive device, which has a catalytic converter with an oxygen accumulator for purifying exhaust gas, includes determining upstream of the catalytic converter a pre catalytic converter molecular mass of a first substance and a pre catalytic converter molecular mass of oxygen; determining a post catalytic converter oxygen molecular mass by applying a first reaction equation which describes a reaction of the oxygen with the first substance, a second reaction equation, which describes a reaction of the first substance with oxygen stored in the oxygen accumulator, and a third reaction equation which describes an introduction of oxygen from the exhaust gas into the oxygen accumulator, wherein a reaction speed of the second reaction equation and a speed of the third reaction equation is a function of a load state of the oxygen accumulator |
