ABSTRACT:
An automotive power pivot door is powered by an electric motor through an electromagnetic clutch. A control device of the door has a control unit configured to carry out a routine which comprises de-energizing an electric motor and disengaging the clutch when the door is lifted up to a full-open position; detecting a moved distance by which the door moves down from the full-open position within a first predetermined time (t1) from the time on which the clutch is disengaged; engaging the clutch when the detected moved distance is equal to or greater than a first predetermined distance (L1); disengaging the clutch again when a second predetermined time (t2) passes from the time on which the clutch is engaged; repeating the process for engaging and disengaging the clutch while following the routine; and judging that the holder fails to operate when the frequency of the engaged condition of the clutch indicates a predetermined frequency.
