Abstract: A control unit is configured to carry out a given controlling of an electric motor when a given operation is carried. The given operation is an operation wherein under operation of a closure mechanism, the door is moved in a close direction passing through an operative position of a half-latch switch and then moved back in an open direction at a position just before the half-latch position. The given controlling is so made that when the moving member takes a position other than a neutral position upon completion of the given operation, the electric motor is rotated in a reversed direction to move the moving member to the neutral position, and when the moving member takes the neutral position upon completion of the given operation, the electric motor is stopped to keep the moving member at the neutral position.

Abstract: An automatic door operating system for a motor vehicle is shown. The system comprises a door closing device which includes an electric motor and a latch plate actuator. The system further includes a control device which, when a latch plate position detecting switch detects a half-latch condition of a latch plate of a door lock device, energizes the motor to run in one direction to turn the latch plate toward a full-latch position and which, when the latch plate position detecting switch detects a full-latch condition of the latch plate, energizes the motor to run in the other direction to turn the latch plate toward a releasing position and which, when a return recognition switch detects the latch plate actuator having returned to its rest position, stops the rotation of the motor in the other direction. The control device includes a control timer which energizes the motor to run in the other direction for a predetermined time from the time on which the control device is energized.

Abstract: A half-latch and full-latch detecting device for an automotive slide door operating system is shown, which comprises:a power feeding start position detecting switch which becomes operated when the door under closing movement comes to a given position just before a half-latch position of the door at which half-latch position a latch plate of a door lock device assumes a half-latch position;a latch plate position detecting switch having a probe which is contactable with an open lever when the open lever is pivotally moved, the open lever being rotatable with a latch pawl which can latch the latch pawl at the half-latch and full-latch positions;a counter circuit electrically connected to both the power feeding start position detecting switch and the latch plate position detecting switch, the counter circuit counting the number of times by which the open lever contacts the probe of the latch plate position detecting switch after the power feeding start position detecting switch is operated; anda judging circuit f
