<P>PROBLEM TO BE SOLVED: To provide an improved biting prevention device for power window detecting a foreign material caught by a wind glass by the current variation of a motor capable of preventing a malfunction due to abrupt variation of electric source voltage. <P>SOLUTION: The biting prevention device for power window glass outputs a signal detecting a variation of an electric source voltage when +B voltage of the electric source feeder VB changes to cross with the threshold voltage which can be obtained as divided voltages of a stabilized voltage, VB 2, for drive of IC (integrated circuit), and detects the rise of the output signal, and carries out mask treatment, and thereafter transfers to the usual control after treatment. In this way, even if an abrupt electric source voltage variation arises, a power window biting prevention device can be provided without malinvertion. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
