Abstract

A device and method for determining a temperature variable, in particular a temperature variable that characterizes the condition of an exhaust-gas treatment system of a combustion engine, are described. The temperature is specified on the basis of variables that characterize the mass flow in the exhaust-gas treatment system, and/or of a second temperature variable that characterizes the temperature upstream from the exhaust-gas treatment system.
