Verfahren zur Steuerung zur Befüllung eines hydrodynamischen Bauelementes und Steuervorrichtung

The invention relates to a method for controlling the filling of a hydrodynamic element (2) in a control unit with at least one transmission element and a lubricant system or operating material supply system (4), whereby said systems are allocated to the hydrodynamic element and the transmission element. The hydrodynamic element comprises a source of operating material (6), a heat exchanger (11), a memory (27) and at least two bucket wheels which form a toroidal working area together. At least one supply pipe and one drain pipe are allocated to said working area. The invention is characterised by a desired variable which can be predetermined for a variable which at least directly characterises the functional state of the hydrodynamic element and which represents an input variable of a control device (8) that is allocated to the lubricant system or operating material supply system which are allocated to the hydrodynamic element and the transmission element. The input variable is used for driving an actuating device in order to influence the operating material supply of the hydrodynamic element. At least three base functional states of the hydrodynamic element can thus be adjusted. In addition, a supply of the lubricant system pertaining to the transmission element can be adjusted in a base functional state. The correcting variable for actuating the actuating device is produced by the desired variable which at least directly characterises the functional state of the hydrodynamic element according to a variable that at least directly characterises the pressure of the drain pipe of the hydrodynamic element.
