PROBLEM TO BE SOLVED: To provide a drive control device for an automatic sliding door which can smoothly execute operation of a sliding door, and at the same time, prevent the looseness of a wire. SOLUTION: When the operation of the sliding door is started, output from a drive motor is increased with the lapse of time (S3) by gradually increasing a duty ratio of the output to the drive motor, the looseness of a drive wire caused by the energized sliding door is prevented, and the operation is smoothed. And, when an operation speed of the sliding door is more than a pre-determined stipulated value (S4), the target speed to become a control target is set lower than usual (S5), the brakes are applied to the sliding door which is accelerated by the bead weight of the door generated by a slope. Also, when the change of the operation speed of the sliding door is changed much more than the pre-determined value (S6), a gain of an operation expression to calculate the target speed is set lower than usual so as to reduce the output of the drive motor, in order to stabilize the operation, and prevent the looseness of the drive wire. |
