Abstract
In an automotive power window system, a controller detects positions of a window glass that moves through driving operation of a motor during the closing operation of a window. The controller reduces a rotation speed of the motor when the window glass reaches a speed altering position. It calculates the amount of reduction in the rotation speed produced by the rotation speed reducing operation. Then, it corrects a rotation speed obtained during the closing operation by compensating for the amount of reduction. It determines whether an obstruction for the closing operation is present based on the corrected rotation speed. If the obstruction is detected, it controls the motor for releasing the obstruction.
