    • The invention relates to a method for manually stipulating the transmission ratio of a continuously variable transmission (CVT) for a motor vehicle. The CVT comprises a control device, a shifting or selecting device, a starting element and a variator for adjusting the transmission ratio, and is driven, in particular, by an internal combustion engine. The control device processes input signals derived from a driver-vehicle system within the framework of an operational strategy for stipulating the transmission ratio, the rotational speed of the drive motor or a variator input rotational speed. The operational strategy automatically selects the transmission multiplication in a first automatic operational mode. In a second manual operational mode, the driver can directly intervene in the selection of the transmission multiplication via the shifting or selecting device. The invention provides that preset, continuous and vehicle speed-dependent engine rotational speed progressions or variator input rotational speed progressions or transmission ratio progressions can be manually selected in the second operational mode. The progressions are displayed as curve traces within an upper and a lower limit of the adjustment range such that vehicle standstill and the highest possible speed of the vehicle can be attained in each progression.

    • The invention relates to a method for setting a multiplication of a continuously variable automatic transmission equipped with a variator (CVT) comprising the following method steps: a) it is determined in a test module (M1, M1') whether an operating situation is present in which a program module (M2, M2') for adapting an existing transmission multiplication (i_v_ist) to a vehicle velocity (v_F) or to an output speed (n_ab) of the transmission is activated; if not present, a transmission specified multiplication (i_v_strategie, i_v_anfahr) is determined as a new transmission specified multiplication (i_v_soll) from a characteristic diagram for a regular driving strategy; b) it is verified in the program module (M2, M2') whether the vehicle velocity (v_F) or the -utput speed (n_ab) of the transmission is greater than a predetermined limiting value (v_F_grenz, n_ab_grenz); c) in the case of a positive inquiry, a predefined transmission specified multiplication (i_v_ABS, i_anfahr_w) which is assigned to the determined operating state is set as a new transmission specified multiplication (i_v_soll) when the starting clutch is activated; in the case of a negative inquiry, a processing function (F4, F17) is begun in order to at least partially open a starting clutch, and the transmission specified multiplication (i_v_ABS, i_anfahr_w) which is assigned to the determined operating state is set as a new transmission specified multiplication (i_v_soll).
