Abstract:
A device and method for operating a fluid-guiding device, including an electrically operated fluid pump, which delivers fluid from a fluid sump of the fluid-guiding device and supplies it to at least one fluid consumer. A fluid volume in the fluid sump as well as a current intensity of the electric current taken up by the fluid pump and modeled on the basis of the rotational speed of the fluid pump are ascertained, and a comparison value is determined from the modeled current intensity. A deficient fluid supply of the fluid-guiding device is inferred if the fluid volume is greater than a threshold value and a measured current intensity of the electric current taken up by the fluid pump is less than the comparison value.
