Title: METHOD FOR CONTROLLING AND/OR REGULATING A CLUTCH WITH A FRICTION SYSTEM, PARTICULARLY A CLUTCH FOR AN AUTOMATIC OR AUTOMATABLE TRANSMISSION OF A MOTOR VEHICLE
Abstract:
The invention relates to a method for controlling and/or regulating a clutch with a friction system, particularly a clutch for an automatic or automatable transmission of a motor vehicle, wherein a clutch torque of the clutch can be controlled and/or regulated and according to the adjustment of a clutch torque, slip is initially adjusted on the clutch. The control and/or regulation is improved in that, when a modification of the friction system is identified, thereby indicating that the actual slip initially exceeds a threshold value for a maximum permissible slip (3) and the actual slip is then smaller than a determined nominal slip (4) for a determined minimum time interval (∆t), a control and/or regulation strategy adapted to the moification of the friction system is activated.
