Abstract

The power train (1) includes a controlled drive source (3), a clutch (6), an automatically shifting transmission (7) and a data transmission device (2). The power train contains an additional drive source (12) 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 (21–27).
