A control unit arrangement for controlling a fluid arrangement includes at least one transmission actuator element, at least one valve and at least one pump, for clutch and transmission activation. The control unit arrangement also includes a plurality of control units. At least one control unit of the plurality of control units is configured to actuate the at least one transmission actuator element and at least one control unit of the plurality of control units is configured to actuate the at least one pump. One of the control units from the plurality of control units is configured to actuate the at least one valve, or at least two of the control units from the plurality of control units are connected via an OR logic for a common actuation of the at least one valve.

Control unit arrangement for controlling a fluid arrangement

A method for adjusting and adapting an operating point of a hydraulic actuator arrangement, in which a volume flow source is connected to a hydraulic cylinder via a pressure line that is filled with a hydraulic fluid. The method includes regulating a volume of the hydraulic fluid by the volume flow source, wherein an operating point of a position of the actuator arrangement corresponds, with respect to a predefined parameter, to a device which is to be actuated by the actuator arrangement. A modified volume of the hydraulic fluid which is necessary to adjust the operating point is derived from a rotational position of a volume flow source motor and/or of the volume flow source.
