Abstract
When a window glass catches an obstacle and driving current of a driving motor increases to a set maximum value, the driving current is controlled within the maximum set value to limit the obstacle catching force. Because the motor is controlled by a duty ratio of PWM signal, the motor speed can be controlled with ease and stable control of the motor is ensured.
