Drive control device for opening/closing member


The drive control device is active to optimally adjust a threshold level for detection of pinching of a foreign body by an opening and closing member such as a vehicle window. The speed of the opening/closing member is detected 23. Based on memorized data, a predicting circuit 36 derives a future speed value. To the predicted value there is added an allowed addition value, to permit a threshold level setting circuit 37 to set an appropriate threshold for pinch detection. The allowed addition value is adjusted in accordance with the speed of the opening/closing member by a threshold level adjusting circuit 38. <IMAGE>
