Verfahren zum Steuern eines Automatgetriebes

摘要

The invention relates to a method for controlling an automatic transmission which is driven by an internal combustion engine. A shift from a first transmission ratio to a second transmission ratio occurs in the form of a pull upshift. A first coupling opens and a second coupling closes, and an electronic transmission control device controls the pressure characteristic of said first and said second coupling during the shifting operation by means of electromagnetic valves. This shifting operation is divided into various shifting phases, an engine intervention taking place in the gradient setting phase (SG), the sliding phase (SL), the gradient reduction phase (RG) and the closing phase (S), an engine torque being reduced by means of an engine intervention factor (mdzegs) being transferred from the transmission control device to an engine control device of the internal combustion engine.
