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.
Claims5
A method for regulating the surface temperature of a glow plug, comprising:
- continuously measuring electrical resistance of the glow plug;
- using the continuously measured resistance and a resistance temperature characteristic to regulate the surface temperature of the glow plug to a target temperature or a target resistance corresponding to the target temperature;
- and
- adjusting the resistance temperature characteristic as a function of the present motor operating state, wherein the present motor operating state is determined by a glow plug control device monitoring the power or voltage that is required to maintain the resistance associated with a given target temperature according to the resistance temperature characteristic used.
