ABSTRACT:
A door-holding control system for a vehicle slide door includes a slide door moved for its opening and closing on and along a guide track of a vehicle body by a slide door Moving mechanism, a clutch mechanism for interruptively transmitting a mechanical power from a drive source to the slide door moving mechanism, movement detecting element for detecting a movement of the slide door, and a clutch control for controlling a power transmission maintenance force of the clutch mechanism. The door-holding control system in improved such that: the clutch control controls the power transmission maintenance force to a minimal value of force required for stopping and holding the slide door while monitoring an output signal of the movement detecting element, and when the power transmission maintenance force exceeds a predetermined value of force, the clutch control controls the power transmission maintenance force to a value of force required for opening and closing the slide door, whereby the slide door is driven for opening and closing by the mechanical power of the drive source.
