Abstract

A method for setting a multiplication of a continuously variable automatic transmission (CVT transmission) comprises the following 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 speed (v_F) or to an output rotational speed (n_ab) of the transmission is activated; in the negative a transmission specified multiplication (i_v_stratagy, i_v_start) is determined as new transmission specified multiplication (i_v_soll) from a characteristic field for a regular driving strategy; b) it is tested in the program module (M2, M2') whether the vehicle speed (v_F) or the output rotational speed (n_ab) of the transmission is higher than a predetermined limiting value (v_F_limit, n_ab_limit); c) in the case of a positive inquiry, a predefined transmission specified multiplication (i_v_ABS, i_start_w) assigned to the determined operating state is set as 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 at least partly open a starting clutch and the transmission specified multiplication (i_v_ABS, i_start_w) assigned to the determined operating state is set as a new transmission specified multiplication (i_v_soll).
