Title: Power window drive control device
Inventor: IWASAKI YUKIO
IPC: E05F15/10
Filed: 1993-10-13
Abstract: PURPOSE:To prevent a window glass from being stopped when it is manually closed, with foreign matter jammed. CONSTITUTION:When the output of the closing command signal of a window glass from an operation switch is stopped, a microcomputer 16 judges whether the motor current from a motor current detecting circuit 20 tends to increase or not. When the judgment is YES, the rotation control of a motor 14 in the closing direction is continued. When the motor current value exceeds a prescribed threshold value while the rotation control of the motor 14 in the closing direction is continued, the motor 14 is rotation-controlled in the opening direction after it is stopped. The window glass is prevented from being stopped when it is manually closed, with a foreign matter jammed.
