Abstract

A method for operating a torque-transmitting system, which is coupled on the input side to an output shaft of a drive assembly and on the output side to an input shaft of a transmission. A torque flux from the drive assembly to the transmission passes via the torque-transmitting system. The torque-transmitting system includes a hydrodynamic torque converter via which a hydraulic path of the torque flux passes, a converter lockup clutch which is arranged functionally in parallel with the torque converter and via which a mechanical path of the torque flux passes, and a control unit which controls distribution of the torque flux between the hydraulic and mechanical paths in such a way that a predetermined overall torque profile is established at the input shaft of the transmission.
