<P>PROBLEM TO BE SOLVED: To provide a nipping detecting device for a power window and a nipping detecting threshold value setting method for easily securing optimal nipping detecting sensitivity with respective doors, and following even a change with the lapse of time while saving memory capacity. <P>SOLUTION: A pulse signal is outputted with every movement of window glass at an equal interval in operation in the full closing direction of the window glass WG. A rotating speed of a motor is arithmetically operated on the basis of the pulse signal with every output of the pulse signal in the operation in the full closing direction of the window glass. A speed difference between the respective rotating speeds before this output time and 5-pulse output time of the pulse signal in the operation in the full closing direction of the window glass WG is detected every time when outputting the pulse signal. A maximum value of the speed difference is set as a nipping detecting threshold value, and nipping is detected by comparing this nipping detecting threshold value with the speed difference arithmetically operated with every output of the pulse signal. <P>COPYRIGHT: (C)2004,JPO |
