    摘要： The shift sequence for a transmission ratio change of a vehicle drive train is determined depending on an operating state of the vehicle drive train existing upon the actual transmission ratio of 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. Output quantities of the model supply at least one target value that determines the shift sequence in terms of characterization and application as input quantities of an optimization routine, by which a minimization of the functional connection of at least one target value is carried out. 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.

    摘要： The invention is based on a process for determination of a coefficient of friction (&mgr;) of a hydraulically activated coupling (4, 5, 6) or brake (7, 8, 9) in a load-shifting transmission (1). It is proposed that a drive shaft (14) of the transmission (1) be driven with a specified torque (T), that an output shaft (15) of the transmission (1) is blocked with a closed coupling (4, 5, 6) or brake (7, 8, 9) during a calibration run, the activation pressure (p) of coupling (4, 5, 6) or brake (7, 8, 9) is reduced in accordance with a specified course over time, the differential rotational speed (&Dgr;n) between the input (17, 18, 19) and the output (20) of the coupling (4, 5, 6) or brake (7, 8, 9) is recorded, the activation pressure (p) is ascertained in which the differential rotation speed (&Dgr;n) is greater than zero and a separation coefficient of friction (&mgr;separation) is computed on the basis of torque (T), activation pressure (p) and a construction-conditioned coupling constant. By ascertaining the coefficient of friction &mgr;, the shifting can be conducted over the lifetime of the transmission (1) with a constant shift quality.
