Abstract

A method for determining the temperature or the ohmic resistance of an electrical component, especially of a coil of a magnetic valve. The component temperature is estimated with the aid of a temperature model, which is able to determine the curve of the component temperature even during a control of the valve. The temperature model is corrected regularly based on the measured value, in this context.
