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.

A device for automatically controlling the open-close of a vehicular sliding door enabling to smoothly change the slide door open-close control system from a manual to an automatic with decreasing any shock generated in changing the mode. Having a drive source (54), such as motor and the like, a slide door (3) able to open and close by the manual or the slide door open-close mechanism, a clutch (56) for conveying intermittently drive force of the drive source to the slide door open-close mechanism, a door speed detector (78), and a slide door controller (7) for controlling the drive source and the clutch in order to adjust the drive force transferred to the slide door open-close mechanism. When the slide door is detected that it is moving at a speed higher than a manual recognition speed, the drive source and the slide door open-close mechanism are connected at a half-clutched condition and then they are connected at a full-clutched condition.

A control system is provided for controlling electric devices installed in a slide door which moves relative to a door opening formed in a vehicle body. The control system comprises a first electric device for detecting a door-closed condition wherein the slide door is at its fully closed position relative to the door opening and a second electric device for positively suppressing operation of the electric devices until the time when the first electric device detects the door-closed condition. For achieving communication between the first and second electric devices, an electromagnetic induction phenomenon is practically used.

A vehicular slide door open-close control apparatus for opening a slide door installed at a side of vehicle body by means of the drive source such as a motor and the like. The purpose of the apparatus is to reduce a burden applied to the slide door moving from its full-open position along its close direction, downsize, lighten and lower the cost. Also, reducing an operational force when the door is manually closed. The control apparatus has a drive source 54 such as motor and the like, a slide door 3 open-close-moved by a slide door open-close mechanism, a clutch means 56 transmitting intermittently a drive force of the drive source 54 to the slide door open-close mechanism, a slope judgement means 76 detecting a vehicle posture and a slide door control means 7 controlling the drive source and clutch means in order to adjust a drive force to be transferred to the slide door open-close mechanism. When a full-open control is done and it is detected that the vehicle parks on a level ground or upward slope, the slide door is stopped just before its full-open position.

A drive control device for an opening/closing member may be advantageously utilized in vehicular power window systems and the like. The drive control device is active to detect occurrence of pinching of an object obstructing the path of motion of the opening/closing member and, upon detection of such pinching during closing operation is controlled so as to move in the opening direction for a predetermined distance for preventing serious pinching from being applied to, for example, a persons hand or arm which may be blocking a power window while being closed by a vehicle driver. The drive control device further includes timing functions such that closing operation may not be immediately resumed after pinch detection, until a predetermined time period has elapsed. The pinch detection operation is effective to compensate for overrun of the opening/closing member caused by a lag between the time a closing control signal is stopped and the acutal motion of the opening/closing member finally and completely stops.

The controller includes a full-latch confirmation section for confirming that the latch member is maintained at its fully-latched position, and a motor-drive limiting section for limiting re-activation of the motor so as to avoid ineffective auto-closing action of the system when the full-latch confirmation section decides that the latch member has already been shifted to and maintained at the fully-latched position.
