Abstract:
The invention relates to a method for operating a glow plug with the engine running, wherein an effective voltage is generated from a vehicle electrical system voltage by pulse width modulation, the effective voltage is applied to the glow plug and changed as a function of engine parameters, a target value of the effective voltage that is dependent on the engine parameters and to which the effective voltage is changed is specified, a maximum increment for a change of the actual value of the effective voltage in at least one direction is specified, and a change of the actual value in at least one direction to a target value that deviates from the actual value by more than the maximum increment is carried out in several steps. The invention further relates to a controller which carries out such a method during operation.
