<P>PROBLEM TO BE SOLVED: To provide a control method which can recognize the case where an opening/closing window is caught and is brought into a dangerous state without using an encoder or the like, which can operate the opening/closing window by a weak force, which can immediately abort the closing operation and reverse, and which can stop when a human being's finger, arm, a cat or the like become caught in the opening/closing window. <P>SOLUTION: In the control method, the voltage placed on a motor and a motor current are monitored at short time intervals, and a motor current which maximizes starting torque is supplied at the time of start of operation of a window surface body. The starting torque is weakened when the window surface body is brought close to a fully-closed position, especially to a dangerous position where a finger or the like is apt to be caught during the closing operation of the window surface body. When it is brought to a nearly fully-closed position passing through the dangerous position, the starting torque is increased, and the opening/closing window is securely closed. <P>COPYRIGHT: (C)2009,JPO&INPIT |
