A wheel suspension assembly () for a vehicle, having a spring damper (), a first transverse link (), which has a first transverse link strut () and a second transverse link strut (), a second transverse link (), a first tie rod (), a second tie rod (), a reversing lever (), a hub carrier (), a steering gear () and a pendulum support (). Each transverse link () has an end (), on the hub carrier side, and two ends (), on the chassis side. The steering gear () is arranged in a plane with the first transverse link () and in a section between an end () of the first transverse link strut () of the first transverse link (), on the chassis side, and an end () of the second transverse link strut () of the first transverse link (), on the chassis side.

Wheel suspension system

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 ( ) of slip meter is locally incremented according to ratio value (iv) and to engine torque (M_mot) and simultaneously an evaluated slip meter ( ) of an evaluation module ( ), likewise according to ratio value (iv) and to engine torque (M_mot), is increased, wherein via the evaluation module ( ), the variator slip is assessed according to duration and intensity. Besides, a characteristic field ( ) of slip status meter connected with the evaluated slip meter ( ) is incremented together with the evaluated slip meter ( ), a signal being passed on to an error memory ( ) so that, with the entry of the error, slip, evaluated slip and slip status meter are entered in the error memory ( ) as environmental conditions. Thereafter the contact pressure security is locally varied according to the characteristic field ( ) of the slip status meter.
