Abstract
In a method for controlling a powered sliding door system, a standard time period for the sliding door to pass a calibration interval defined near a fully closed position under a standard duty ratio condition is measured, and the duty ratio of the drive pulse signal for the motor in the remaining interval of operation is determined from this standard time period so that the sliding door may move at a prescribed speed irrespective of the load acting on the door. This control method can be favorably used in combination with the process of detecting an obstacle in the path of the sliding door, which is based on the detection in the reduction in the speed of the sliding door, without any interference between them.
