Abstract
A power window device that suppresses heating in a motor used to lower and raise a window glass. For each door of a vehicle, the power window device includes an ECU that controls a motor in accordance with the operation of a switch to raise the window glass. A pulse sensor is arranged in the vicinity of the motor to detect the rotation speed of the motor and generate a detection signal. Based on the pulse signal of the pulse sensor, the ECU determines whether the window glass has reached a fully open or fully closed position. When it is determined that the motor has become locked or that the window glass has reached the fully open or fully closed position, the ECU deactivates the motor until predetermined activation conditions are satisfied.
