Abstract
The power train () includes a controlled drive source (), a clutch (), an automatically shifting transmission () and a data transmission device (). The power train contains an additional drive source () and is fitted with a control system by means of which a correction value (K pid) for the drive source torque is generated on the basis of the comparison of the actual behavior of the drive train with a modeled behavior of a drive train fitted with a hydrodynamic torque converter. The behavior of a torque converter is simulated by a regulating circuit ().
