Abstract
Methods and systems are provided for model-based determination of a temperature distribution of an exhaust aftertreatment system of a vehicle. A power demand from a first component of the aftertreatment system is measure, a heat transfer into the first component of the aftertreatment system based on power demand of the first component and a configurable emissivity value of the exhaust gas is determined, and the temperature of the first component based on the calculated heat transfer is calculated.
