Operating method for motor vehicle power train, by defining mode for approximating rotation speed of torque generator to rotation speed of transmission shaft

摘要

The method involves defining an approximation mode for approximating the rotation speed of a torque generating device to the rotation speed of a transmission shaft associated with the target gear, based on operating parameters and/or driver-stipulations. In a first approximation mode, the torque generating device is controlled by raising or reducing the torque. In a second approximation mode, the respective clutch is controlled to increase the torque transferred. Independent claims are included for further operating methods, and for a power train.
