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.
