<P>PROBLEM TO BE SOLVED: To provide a driving device of a power window, surely detecting clipping of a power window even in running on a bad road, and preventing wrong reversion. <P>SOLUTION: This driving device has a function of driving the driving motor M1 of the power window mounted on a vehicle to rotate in a reverse direction, and stopping the driving motor M1 or reversing the same when a steep current increase is caused in the driving motor M1 during the operation of the power window. When a frequency variation is caused in a designated frequency band in a current flowing through the driving motor M1, the interval between a reference value in detecting the steep current increase and the signal level corresponding to the electric current flowing through the driving motor M1 is controlled to expand. <P>COPYRIGHT: (C)2004,JPO |
