    摘要: A method is described for control of a CVT automatic transmission (1) in which a sensed main pressure (p_hd_act) and a sensed contact pressure (p_s2_act) of a secondary pulley (7) are entered as signals in an electronic transmission control (8). For diagnosis of an error in the sensing of the main pressure (p_hd_act) and/or of the contact pressure (p_s2_act) of the secondary pulley (7) their actual values or comparison variable (|p_hd_act-p_hd_nom|, |p_s2_act-p_s2_nom|) formed therefrom are compared with applicable threshold values (p_hd_min, pd_phd_regdiff, p_s2_min, pd_ps2_regdiff) associated with a range of plausible pressure values.

    摘要: Within the scope of the process for variator slip treatment in continuously variable automatic transmissions of a motor vehicle, upon detection of variator slip, a characteristic field (1) of slip meter is locally incremented according to ratio value (iv) and to engine torque (M_mot) and simultaneously an evaluated slip meter (2) of an evaluation module (3), likewise according to ratio value (iv) and to engine torque (M_mot), is increased, wherein via the evaluation module (3), the variator slip is assessed according to duration and intensity. Besides, a characteristic field (4) of slip status meter connected with the evaluated slip meter (2) is incremented together with the evaluated slip meter (2), a signal being passed on to an error memory (5) so that, with the entry of the error, slip, evaluated slip and slip status meter are entered in the error memory (5) as environmental conditions. Thereafter the contact pressure security is locally varied according to the characteristic field (4) of the slip status meter.
