Abstract

See full text

A method for controlling a hydrodynamic machine, including the steps of: providing a hydrodynamic machine which includes a bladed primary wheel and a bladed secondary wheel, which together form a working chamber, which can be filled with a working medium from a working medium supply contained in a working medium reservoir, to transfer drive power hydrodynamically from the bladed primary wheel to the bladed secondary wheel by forming a working medium circuit in the working chamber; applying a control pressure to the working medium supply in order to force the working medium from the working medium supply into the working chamber; detecting, at least indirectly, a pressure increase in the working medium reservoir, when the control pressure is applied to the working medium supply; and determining, as a function of the pressure increase that has been detected, a fill level of the working medium supply in the working medium reservoir.
