Powertrain of a Motor Vehicle and Method for Controlling Said Powertrain
First Claim
1. A motor vehicle powertrain comprising a controlled power source, a clutch, an automatically shifted transmission and a data transfer system enabling data to be exchanged between the component parts of the powertrain, an additional power source, and a control system for producing a correction value for the power source torque on the basis of a comparison of the real behavior of the powertrain with a modeled behavior of a powertrain provided with a hydrodynamic torque converter.

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).
