Abstract
In at least some implementations, a cable control system includes a spool on which a portion of a cable may be taken up and released, an input shaft coupled to the spool, and a motor coupled to the input shaft to drive the input shaft and spool in a first direction to take up cable on the spool and in a second direction to release cable from the spool. The control system also has two clutches that allow rotation of the spool without corresponding rotation of the motor. Each clutch may have a first member coupled to the input shaft and a second member coupled to the spool and relative rotation between the first and second members of the clutch allows rotation of the spool relative to the motor or input shaft.
