Abstract
A method for regulating the surface temperature of a glow plug is described, wherein the electrical resistance of the glow plug is continuously measured and used to regulate the surface temperature of the glow plug to a target temperature or a target resistance corresponding to the target temperature by means of a resistance temperature characteristic. According to this disclosure, it is provided that the resistance temperature characteristic used for the temperature regulation is adjusted as a function of the present motor operating state.
