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.

1. A process for treatment of variator slip in a continuously variable automatic transmission, the process comprising the steps of, upon detection of variator slip, increasing a characteristic field (1) of a slip meter according to a ratio value (iv) of a variator and to an engine torque (M_mot) of
1. A process for treatment of variator slip in a continuously variable automatic transmission, the process comprising the steps of, upon detection of variator slip, increasing a characteristic field (1) of a slip meter according to a ratio value (iv) of a variator and to an engine torque (M_mot) of a prime mover and simultaneously an evaluated slip meter (2) of an evaluation module (3), likewise according to the ratio value (iv) of the variator and to the engine torque (M_mot), is increased, assessing the variator slip according to a duration and an intensity by the evaluation module (3), and increasing a characteristic field (4) of a slip status meter connected with said evaluated slip meter (2) together with said evaluated slip meter (2), passing a signal to an error memory (5) in such a manner that, with the entry of an error, the slip, an evaluated slip and a slip-status meter are entered in said error memory (5) as environmental conditions and, depending on the characteristic field (4) of the slip-status meter, a contact pressure security of said variator is locally varied as a function of the variator ratio (iv) and the engine torque (M_mot), and deleting the error entry by deletion of the error memory (5), and said characteristic field (4) of said slip status meter being deleted independently and separately of said error memory.
