ABSTRACT:
A method for the control of a gear change of an automatic discrete step gearbox of a motor vehicle superimposes a regulation of the gearbox input rotational speed during a rotational speed adaptation phase on a control of the transmission torque of a frictional connection. A required deceleration value is specified as a function of a deceleration torque to be brought about by the frictional connection.
