  • Patent number: 6178699
    Abstract: An open/close control system for a vehicle slide door includes in one embodiment, a drive source, e.g., a motor, a slide door opening/closing mechanism, a clutch for transmitting a drive force of the drive source to the opening/closing mechanism interruptively, movement signal generator for generating a signal dependent on the moving direction of the slide door, and slide door controller for controlling the drive force to be transmitted to the opening/closing mechanism by controlling the drive source and the clutch. The slide door controller stops the operation of the drive source and thereby stops the slide door, declutches the clutch to allow the slide door to be movable, detects a movement of the slide door caused by its weight by use of an output signal of the movement signal generator, and determines an inclination of the vehicle on the basis of the detection result.

  • Patent number: 6145917
    Abstract: A door operating apparatus for a vehicle back door is comprised of a wire, a winding mechanism, a guide pulley, a tension mechanism and a stopper. The winding mechanism is installed at one of a vehicle body and the back door and is connected to an end of the wire. The winding mechanism winds and releases the wire according to a command signal. The guide pulley is installed at the other one of the vehicle body of the back door with respect to the winding mechanism and supports the wire. The tension mechanism is connected to the other end of the wire and always pulling the wire. The stopper prevents the wire from being sent from the tension mechanism at a predetermined point. Therefore, even if the back door is manually opened and closed, the wire is kept in a tensioned state by means of the tension mechanism to enable smooth opening and closing during manual operations.
