Abstract

A method for driving a drive assembly in a drive system having an automatic transmission and an automatic clutch optionally coupling the drive assembly to the automatic transmission in order to transmit torque includes the following steps. Sensing whether a procedure, in particular a gearshift operation, is to be conducted. After the procedure has been sensed, predefining, for at least one time segment of the procedure which is to be carried out a prediction profile for an operational variable that characterizes the operating state of the drive assembly. And, driving the drive assembly based on the predefined prediction profile of the operational variable to minimize a deviation between the operational variable and the prediction profile.
