Abstract

In a method of controlling an automatic clutch disposed between a motor, especially an internal combustion engine, and the drive train of a vehicle which includes an arbitrarily operable transmission, the clutch is engaged in dependence on the torque generated by the motor in such a manner that the torque which can be transmitted by the clutch is only slightly above the motor-generated torque and, immediately after a transmission ratio change, the clutch is first fully engaged for the transmission of maximum torque if the motor torque exceeds a certain threshold value.
