Apparatus for controlling driving of power window system

摘要

An apparatus for controlling driving of a power window system having a motor drive current detection device for detecting a current flowing through the motor when the door glass is raised by the motor, a current variation calculation device for calculating a variation amount of the current detected by the motor drive current detection device, and a drive control device for stopping or reversing the motor when the variation-amount of the current exceeds a predetermined value and the gradient of the variation amount of the current is positive when the variation of the current starts. The apparatus can quickly and accurately judge whether an abnormal current is caused by noises or the squeeze of an alien substance, thereby eliminating unnecessary operations of the motor.
