Various embodiments include method for determining a temperature of an active layer of a heating resistor for a recuperation system of a motor vehicle comprising: determining an instantaneous value of a current flowing through the active layer of the heating resistor at a first time; determining an instantaneous value of a voltage present on the active layer at the first time; calculating an instantaneous value of an electrical resistance based on the determined instantaneous value of the current and the determined instantaneous value of the voltage; and determining an instantaneous value of a temperature of the active layer from the calculated value of the electrical resistance.
