There is provided a method for controlling a hydrodynamic retarder. The method includes determining a presence of a retarder switch-off request, and keeping a separating clutch closed, after the determining, for a preset time span and emptying a working chamber of the hydrodynamic retarder of a working medium by continuous actuation of a rotating bladed rotor and interruption of infeed of the working medium into the working chamber. The method further included varying the preset time span according to at least one of the following parameters or at least one parameter correlated with one of the following parameters: a rotational speed of the rotating bladed rotor, an output pressure, against which the working medium is emptied from the working chamber, a filling level of the working chamber with the working medium, a temperature of the working medium, and a braking torque of the hydrodynamic retarder.
