Operating a Catalytic Converter Device in a Motor Vehicle

Various embodiments may include a method for operating a catalytic converter device comprising: measuring electrical properties of the catalytic converter using high-frequency electromagnetic waves; determining a current operating state of the converter; acquiring reference points associated with the operating state; and checking a calibration of a measuring device. The operating states are selected from: an accumulator is completely emptied; an accumulator is completely filled; an accumulator is partially filled; a component to be stored is put into storage; a component to be stored is removed from storage; and an exhaust gas component to be converted or a quantity of the catalyst material in the exhaust gas which exceeds a threshold value is detected. The component to be stored is selected from the group consisting of: a catalyst material and the exhaust gas component.
