A power drive system is adapted for a sliding door mounted on at least one side of a vehicle for sliding movement forwardly and rearwardly of the vehicle. The system includes a reversible motor. A bracket is guided within a guide along a fixed path between the opened and closed positions of the door. An elongated drive member is slidably disposed within the guide and connected to the bracket at one end for driving the bracket along the fixed path. A translator mechanism operably engages with the drive member for powering movement of the door. The translator mechanism can include a rotatable hub, operably engageable with the drive member, a gear transmission for driving the hub, and a clutch mechanism for connecting the motor to the transmission. The translator mechanism preferably has sufficient power to pull the sliding door into a primary latch position with respect to the corresponding portions of a latch mechanism attached to the door and frame defining the door opening. A power striker moves the door into and out of sealing engagement with the frame. A lock mechanism selectively maintains the latch in a locked position. At least one sensor provides an input signal to a control system corresponding to movement of the door, position of the lock mechanism, and position of the power striker for controlling the door drive unit, power striker drive unit, and lock mechanism drive unit in accordance with a program stored in memory.

1. An apparatus for controlling movement of a movable closure comprising:a moveable member for movement along a fixed path of travel between first and second end limits of movement; first means including a reversible electric motor for selectively driving the moveable member in a first direction and in a second direction opposite from the first direction along the fixed path of travel; at least one sensor disposed between the first means and the moveable member for generating at least one input signal corresponding to motion of the moveable member along the fixed path of travel; control means responsive to said at least one input signal for selectively actuating said first means in accordance with a control program; a clutch disposed between the reversible electric motor and the moveable member; a sensor mounted to a portion of the clutch for sensing movement of the clutch when the moveable member moves along the fixed path; and the control means including means for controlling the moveable member while moving between a first position and a second position along the fixed path in response to said sensor mounted to the portion of the clutch disposed between the reversible electric motor and the moveable member.
