A method is described for setting a temperature of a glow plug, in particular for igniting a fuel/air mixture in an internal combustion engine in which the temperature of the glow plug is set as a function of a resistance of the glow plug with the aid of a control. To prevent temperature overshoots from occurring during the preheating phase of the glow plug, the temperature is controlled with the aid of a predictive model during a preheating phase during which an overvoltage is applied to the glow plug.

Method and control unit for setting a temperature of a glow plug

A device and a method for controlling at least one glow plug of a motor vehicle are described. The at least one glow plug is controlled as a function of the operating state of the internal combustion engine. In this case, the control is effected as a function of a variable which depends on the exhaust gas temperature and/or as a function of the fulfillment of a fuel quantity condition and/or time condition.
