Title:
POWER WINDOW CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2628808
Kind Code:
B2
Abstract:
PURPOSE: To suppress the erroneous action of the opening/closing control of a window glass, and ensure the minimum action at the time of a failure.
CONSTITUTION: A main control circuit 1 and other sub-control circuits 8-10 are connected by one serial signal line 17. Lock mode setting pulses corresponding to either the normal state setting or the locked state setting are periodically outputted from the main control circuit 1, and the opening/closing control of a window glass and the locked state setting are performed by the sub-control circuits 8-10 while the lock mode setting pulses are received. When noise is mixed or the serial signal line 17 is opened, the lock mode setting pulses are not periodically inputted, thus the abnormal state can be judged, and the erroneous action can be prevented.
