<p>[0030] The present invention discloses a force regulated anti-pinch window regulator system. The system includes a motor (2) with a means to control the direction of rotation (1) of the motor (2) and hence the movement of a window glass. The system also has two comparators, wherein each comparator receives two inputs. The system has a controller unit (8) which governs the current regulation within the upper threshold value of the first comparator (6). The current regulation is achieved by hysteresis current control method. If the value of current is between the upper threshold and the lower threshold for a certain period of time Thigh, an intrusion is detected. Correspondingly, the motor is stopped in the case of a hard intrusion, and the direction of movement of the window is reversed completely or for a timed duration in the case of a soft intrusion.</p> |
