Abstract
In a method for ascertaining a temperature of a sheathed-element glow plug in an internal combustion engine, a temperature difference between the temperature of a glow plug heater inside the sheathed-element glow plug and a temperature at an arbitrary location on the sheathed-element glow plug is determined as a function of at least one operating parameter of the internal combustion engine and/or at least one operating parameter of the sheathed-element glow plug. The temperature of the sheathed-element glow plug is ascertained from a temperature value represented by a measured value, and from the determined temperature difference.
