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 (-).

Powertrain of a motor vehicle and method for controlling said powertrain

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 ().

A torque set value is determined in a pedal interpretation unit () from a parameter which characterizes the drivers command. Operating parameters for the vehicle are evaluated and classified in a driver and situation recognition unit (). A set operating status for the drivetrain is fixed in a status manager (), depending upon the torque set value and the output signals from the driver and situation recognition unit. Control signals for remote control units () for the drive units and for the gearbox () are then generated in a torque manager (), dependent upon the torque set value and the set operating status.
