Abstract
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 locall…
