The invention concerns a hydrodynamic retarder having a rotor which can be brought into rotation via a drive unit and a fixed stator or a stator rotating in opposite direction to the rotor, whereas the rotor and the stator comprise bladed wheels, which form together a working chamber which can be filled with working medium; the drive unit is provided with a separating clutch, by means of which the rotor can be disconnected for its immobilisation, comprising a driven primary side and a secondary side associated with the rotor; having a control device which controls the opening and closing of the separating clutch for switching the retarder (17). The invention is characterised in that the control device when closing the separating clutch detects the run-up behaviour of the secondary side of the separating clutch and/or of the rotor via at least one associated sensor or defines the run-up behaviour from at least one input value supplied thereto and according to the run-up behaviour initiates either the continuous closing of the separating clutch for slip bridging between the primary side and the secondary side for accelerating the rotor or the interruption of the closing process of the separating clutch.
