Abstract

To achieve precise control of a clutch arranged inside a converter housing (1) and which connects the converter housing (1) to a pump impeller wheel (3), the converter's internal pressure, which acts on a piston (9) of the actuation device of a clutch (2), is determined by a pressure sensor (12) and the actuation pressure, which acts on the piston (9) in the opposite direction, is adjusted accordingly.
