Filed: 1993-01-18
Abstract: PURPOSE:To obtain a highly operable drive controller for power windows which can nearly sufficiently detect the interposition of foreign matters, etc., and, at the same time, can make an interposition detecting function to work only when it is required. CONSTITUTION:In the section (in the circle D of (3)) where the control of reversing and stoppage of a motor is forcibly inhibited at the time of an overload to the motor after the switch of (1) is turned on, a threshold SL for detecting the overload of a motor current is changed to another threshold SH which is larger than a larger threshold SH which is larger than the current value of the motor. Thereafter, the control of reversing and stoppage of the motor is not made at the time of an overload in the section unless the motor current of (3) exceeds the threshold SH even when the switch of (1) is turned off. Therefore, when door glass is not completely closed due to the working of the door, the door glass is completely closed by operating the switch of (1) by one time and the same operations as those performed at the time of detecting interpositions are not repeated when the door glass is at the same position. Thus the operability of this device is improved.
