09822573 · 2017-11-21 · ·

An apparatus and method of controlling a power window by using an output current of a driving motor. The output current is measured to calculate and store a current reduction time, and then, execution of a safety function is delayed when an interruption in ascending of the window glass is sensed, so that interruption caused by noise generated when a car moves over an unpaved road or road bumps may be distinguished from interruption caused by an actual obstacle. Then, the safety function is prevented from being executed if the interruption in the ascending of the window glass is caused by the noise. Therefore, the interruption of the ascending of window glass due to the noise generated when the car moves on the unpaved road or road bumps may be distinguished without using an additional sensor.
