Abstract
A clutch control system for moving an object, such as a vehicle door, lift gate or trunk, compares the motor speed with the object speed and engages the clutch when the motor and object speeds are almost equal. Controlling engagement based on the object and motor speeds ensures smooth transitions into a power assist mode and between the power assist mode and a power release mode without causing clutch shock.
