Abstract
An adaptive control system controls the slip across a start clutch located up-stream of a continuously variable transmission to allow the clutch to be use as a torsional isolator in a continuously variable transmission. The system includes a torsional vibration detector for determining the actual level of torsional vibrations transmitted by the clutch. The actual level of vibrations is compared with an acceptable level and the slip across the clutch is regulated in order to maintain the transmission of vibrations to the acceptable level.
