A method for determining a shift sequence of a change of transmission ratio of a transmission device of a vehicle drive train is described. The shift sequence is determined depending on an operating state of the vehicle drive train existing upon the actual transmission ratio inserted in the transmission device. The operating state is characterized by various operating state quantities of the vehicle drive train, which represent input quantities of a model representing the vehicle drive train (B2). Output quantities of the model (B2) supply at least one target value that determines the shift sequence in terms of characterization and application, in the form of a functional connection and limits of the operating state quantities or of combinations of operating state quantities as input quantities of an optimization routine (B1), in the area of which a minimization of the functional connection of at least one target value is carried out, and the torque characteristics representing the shift sequence of devices of the vehicle drive train are determined depending on the minimum of the functional connection of at least one target value, taking into account the limits of the operating state quantities. In the area of the devices, during each change of transmission ratio, a torque is introduced in the vehicle drive train and/or a torque leading into the vehicle drive train is changed. |
