Control systems including control circuitry and optional communications systems for operating a sliding power-operated member of an automotive vehicle. A powered sliding door in an automotive vehicle, such as a van, moves along a predetermined path of travel between a closed position and a fully open position relative to the body of the vehicle. Such a sliding door may be provided with one or more electrically-operated actuators for performing functions associated with the door, such as power opening and closing the door, power unlatching the door, power locking and unlocking the door, and power clamping and unclamping the door in a soft or low-momentum manner. The invention is directed toward improved control systems and circuitry for operating such power-sliding door systems. One such control system employs a wireless communications link between the door and body, which is preferably implemented using radio frequency communication signals containing digitally encoded control signals. Control circuitry is preferably provided in the body and the door of the vehicle for supervising and carrying out the foregoing functions in an orderly manner in response to requests generated locally at the door or remotely by the driver from the console of the vehicle. A second, simpler, control system provides electrically-actuated mechanisms for unlatching the door and operating the door lock without the use of either a wireless communication system or a retractable electrical cable interconnecting the sliding door to the vehicle body.

A control system for operating a sliding power door which traverses along a predetermined travel path between a closed position and fully open position, and which is mounted to a body portion of a self-propelled motor vehicle, the control system comprising: first electric actuation means, including a first electric motor mounted to the body portion, for driving the door in a first traverse direction, and in a second traverse direction opposite the first direction; second electric actuation means, including a second electric motor mounted to the body portion, for operating a low momentum door clamping mechanism for drawing the door firmly against the body portion, and for releasing the door from same; third electric actuation means, including a third electric motor, located within the door, for latching and unlatching a latch mechanism which helps hold the door in place relative to the body; and fourth electric actuation means, including a fourth electric motor located within the door, for locking and unlocking the door.
