Abstract
To be able to determine the torque of a turbine rotor (7) with precision even when a clutch (3) is operated with slippage, a rotation speed sensor (13) determines the speed of a pump impeller wheel (2) and a rotation speed sensor determines the speed of the turbine rotor (7), and the speed signals are transmitted to an electronic control unit which, with reference to stored torque converter data, determines the torque of the turbine rotor.

1-10. (CANCELED)
A hydrodynamic torque converter, comprising a clutch (3) arranged ahead of a pump impeller wheel (2) and connected to a drive mechanism, a turbine rotor (7) forms a drive output, such that in order to determine torque of the turbine rotor (7) a rotation speed of the turbine rotor (7) is detected by a speed sensor and transmitted to an electronic control unit, a rotation speed of the pump impeller wheel (2) is transmitted by a speed sensor (13) to the electronic control unit.
