To control one clutch (2) in a hydrodynamic torque converter, the pressure acting upon one first piston area (4) is supplied to a control unit which, depending on the pressure, adjusts the pressure acting upon a second piston area (5). It is possible to exactly adjust the piston force acting upon a clutch (2) even in the presence of changing pressure ratios within the hydrodynamic torque converter.
