Abstract:
1. An opening and closing body control device comprising: an actuation means for actuating an opening and closing body which opens and closes relative to an opening of a body; a speed detection means for detecting moving speed of the opening and closing body by the actuation means; a control means for driving the actuation means based on detected results from the speed detection means, the control means for conducting anti-pinch transaction for movement of the opening and closing body when an object is pinched between the opening and closing body and the body; wherein the control means includes a speed difference calculation means for calculating speed difference between latest speed and speed at predetermined time earlier of the opening and closing body on the basis of the detected results from the speed detection means; a speed difference memory means for memorizing predetermined number of the speed differences; an accumulation means for calculating accumulation value by accumulating predetermined number of speed differences; and a pinch detection means for conducting anti-pinch transaction of the opening and closing body by comparing the accumulation value and reference value for occurrence of pinch.
