Abstract

A method for matching an actual characteristic curve or diagram that characterizes the operating mode of a hydrodynamic component to a set characteristic curve or diagram is provided. The method includes a set characteristic curve or diagram of the hydrodynamic component is stored in a writable/readable memory storage unit a set manipulated variable being assigned to each operating point; the current actual characteristic curve is determined from the operating parameters that characterize the individual operating states and, for each operating point, is compared with the given set characteristic curve or diagram, a correction of the set manipulated variable being carried out for the respective operating point in the event of a deviation beyond a preset range of tolerances; and, in the event a deviation does not occur, the current set value is set as the new set value and read into the memory storage unit as a set manipulated variable.
