<P>PROBLEM TO BE SOLVED: To provide a window opening/closing control device which can prevent erroneous determination of pinching by a simple means without achieving synchronization between an oscillation cycle and a motor rotation cycle. <P>SOLUTION: According to the operation of the opening/closing control device, if an acceleration sensor does not detect acceleration at a predetermined value or more, a speed value detected by a rotational speed detecting section 81 is directly supplied to a variation calculating section 83 without passing through a low pass filter 84. The variation calculating section 83 calculates a variation of speed, based on the speed value, and a pinching determining section 85 compares the variation with a threshold value, and determines whether or not pinching has occurred. If the acceleration sensor 7 detects the acceleration at the predetermined value or more, the speed value detected by the rotational speed detecting section 81 is changed to a smaller value by subtracting a high-frequency component from the speed value by the low pass filter 84, and then supplied to the variation calculating section 83. The variation calculating section 83 calculates the variation of speed, based on the reduced speed value, and the pinching determining section 85 compares the variation with the threshold value, and determines whether or not pinching has occurred. <P>COPYRIGHT: (C)2007,JPO&INPIT |
