Abstract
A method for operating power window apparatus with a safety device which stops the closing operation of the window in response to the detection of an object-caught state, which prevents the incomplete close of the window, and can accurately detect the object-caught state. The opening/closing position of the window is detected by counting pulses generated as the window moves. A region where a safety control can be carried out is determined on the basis of the detected opening/closing position. When the window reaches a position near a position where the window is fully closed, the count indicative of the opening/closing position detector is reset. The resetting operation is carried out so that a time point where the relative speed of the window is reduced is set at the fully closed position of the window.
