Title:
POWER WINDOW DRIVE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP3909847
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an improved power window nipping preventive device for rapidly detecting an abnormal current caused in a motor current by nipping of a foreign matter without wrong recognition to limit the motor current.
SOLUTION: The power window nipping preventive device comprises a motor current detecting range extension circuit 3b for increasing the ratio of a current detection circuit composed of a shunt resistance R1 and a reference resister R20, when the motor current ID is increased by the nipping, and a first reference voltage Vc2 becomes lower than the voltage input range of each active element of a tracking current circuit 3a such as an AMPA and a CMP 1, to extend the nipping detectable range.
