Abstract

Various embodiments include an apparatus for ascertaining a heating temperature of a heating element for an electrically heatable catalytic converter comprising: a catalytic converter housing surrounding the heating element and the catalytic converter; a first temperature sensor arranged in the housing; and a second temperature sensor arranged in the housing downstream of the first temperature sensor with regard to an exhaust gas flow direction within the housing. The first temperature sensor is exposed to radiation from the heating element and the second temperature sensor is shielded from radiation from the heating element.
