Abstract
An apparatus for detecting an obstacle to a power regulated window, which can detect existence of an obstacle by a method of differential current at low rotating speed of a motor and reduce a force of biting an obstacle and prevent from detecting an obstacle unexpectedly at high rotating speed, includes current detecting means for detecting a value of load current flowing through the motor, reference-value generating means for generating a reference value correspondingly to rotating speed of the motor for judging when the value of load current exceeds a predetermined value of over-load current, and comparing means for judging whether or not the value of load current exceeds the reference value.
