Abstract
Engagement of a clutch is at least partially controlled based upon the difference in rotational speed between the drive side of the clutch and the driven side of the clutch. As the rotational speed difference varies, the approach rate of the drive side and the driven side also varies for at least part of the total distance defined between the drive side and the driven side when the clutch is disengaged.
