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.

In a control system for coordinating operations of interacting components separated by a varying distance located on two portions of an automotive vehicle in which at least one of the components moves relative to the vehicle and each portion of the vehicle includes, a bidirectional transceiver for wireless communications, each transceiver comprising: super-regenerative amplifier means for transmitting and receiving communications signals containing control signals used by the control system, said super-regenerative means having a limited range of operation in accordance with said varying distance up to a predetermined maximum distance, wherein the super-regenerative amplifier means broadcasts less than about one hundred microwatts of transmitted power as measured anywhere along a locus of intended reception points; and interface means for encoding said control signals into said communication signals for transmission by said super-regenerative amplifier means and for decoding said communication signals received by said super-regenerative amplifier means into said control signals.
