Abstract
In a method of automatically operating a clutch release bearing to re-engage a friction clutch adapted to transmit between first and second shafts a torque conditioned by the action of the release bearing on a clutch release device associated with the clutch, the clutch release bearing has a predetermined total travel. This extends between a clutch released position in which no torque is transmitted between the shafts and a clutch engaged position in which the shafts are coupled together in rotation. The clutch release bearing is moved according to speed modes selected from a plurality of predetermined speed modes according to the rotation speeds of the first and second shafts or the gear ratio. During a first phase the clutch release bearing is moved in accordance with a first or fast speed modes over at least a predetermined approach travel. Beyond this the changing difference between the rotation speeds of the two shafts is monitored. When a decrease in this difference is detected, a second or slow speed mode is substituted for the first speed mode.
