Abstract
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.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
124 words
A door-holding control system used with a vehicle slide door, comprising: (A) a slide door moving mechanism that moves the slide door along a vehicle body, said slide door moving mechanism including a drive source and a clutch mechanism that interruptively transmits a mechanical power from said drive source to the slide door; (B) movement detecting means for detecting a movement of the slide door; and (C) clutch control means for controlling a power transmission maintenance force of said clutch mechanism, wherein said clutch control means controls the power transmission maintenance force to a minimal value of force that stops and holds the slide door between a full open and a full close position, while monitoring an output signal from said movement detecting means.
Claim 2
Dependent Claim
124 words
A door-holding control system used with a vehicle slide door, comprising: (A) a slide door moving mechanism that moves the slide door along a vehicle body, said slide door moving mechanism including a drive source and a clutch mechanism that interruptively transmits a mechanical power from said drive source to the slide door; (B) movement detecting means for detecting a movement of the slide door; and (C) clutch control means for controlling a power transmission maintenance force of said clutch mechanism, wherein said clutch control means controls the power transmission maintenance force to a minimal value of force that stops and holds the slide door between a full open and a full close position, while monitoring an output signal from said movement detecting means.
Claim 3
Dependent Claim
52 words
The door-holding control system for a vehicle slide door according to claim 1, wherein, when the power transmission maintenance force exceeds a predetermined value of force, said clutch control means controls the power transmission maintenance force to a value of force that would be required to open and close the slide door.
Claim 4
Dependent Claim
107 words
The door-holding control system for a vehicle slide door according to claim 1, wherein, when said movement detecting means has detected that the slide door has moved from a position near a full-open position to the full-open position and said clutch control means has received the signal from said movement detecting means, said clutch control means controls the power transmission maintenance force to a value that would prevent the slide door from moving from the full-open position, and after a preset time elapses, said clutch control means controls the power transmission maintenance force to a minimal value of force required for stopping and holding the slide door.
Claim 5
Dependent Claim
65 words
The door-holding system for a vehicle slide door according to claim 1, wherein, when the movement detecting means has detected that the slide door has moved in an opposite direction to a direction in which a weight of the slide door bears, said clutch control means controls the power transmission maintenance force to a value of force required to open and close the slide door.
Claim 6
Dependent Claim
44 words
A door-holding control system for a vehicle slide door as claimed in claim 1, wherein, when the power transmission maintenance force exceeds a predetermined value, the controller controls the power transmission maintenance force to a value required to open and close the slide door.
Claim 7
Dependent Claim
60 words
A door-holding control system for a vehicle slide door as claimed in claim 5, wherein the controller controls the power transmission maintenance force to a value required to stop the slide door from moving from the fully-opened position when the sensor indicates indicating that the slide door has moved from a position near the fully-opened position to the fully-opened position.
Claim 8
Dependent Claim
40 words
A door-holding control system for a vehicle slide door as claimed in claim 6, wherein, after a preset time elapses, the controller controls the power transmission maintenance force to a minimum value required to stop and hold the slide door.
Claim 9
Dependent Claim
61 words
A door-holding control system for a vehicle slide door as claimed in claim 5, wherein the controller controls the power maintenance force to a value of force required to open and close the slide door when the sensor indicates that the slide door is moving in a direction opposite to a direction in which a weight of the slide door bears.
Claim 10
Dependent Claim
110 words
A door-holding control system used with a vehicle slide door, comprising: a slide door moving mechanism that moves the slide door along a vehicle body, the slide door moving mechanism including a drive source and a clutch mechanism that interruptively transmits power from the drive source to the slide door; a sensor that detects movement of the slide door; and a controller that controls a power transmission maintenance force of the clutch mechanism, wherein the controller controls the power transmission maintenance force to a minimum value that stops and holds the slide door between a full open and a full close position while monitoring an output signal from the sensor.
Claim 11
Dependent Claim
110 words
A door-holding control system used with a vehicle slide door, comprising: a slide door moving mechanism that moves the slide door along a vehicle body, the slide door moving mechanism including a drive source and a clutch mechanism that interruptively transmits power from the drive source to the slide door; a sensor that detects movement of the slide door; and a controller that controls a power transmission maintenance force of the clutch mechanism, wherein the controller controls the power transmission maintenance force to a minimum value that stops and holds the slide door between a full open and a full close position while monitoring an output signal from the sensor.
