Claim:
1. A method of controlling a power trunk or a power tailgate in a power trunk or tailgate control system for controlling operations of the power trunk or the power tailgate in a vehicle having the power trunk or the power tailgate, the method comprising: checking whether the power trunk or the power tailgate has an open operation state or a close operation state; measuring, using a first Hall sensor, a Hall effect count of a left spindle motor for driving a left spindle and, measuring using a second Hall sensor, a Hall effect count of a right spindle motor for driving a right spindle used to open or close the power trunk or the power tailgate if the power trunk or the power tailgate has the open operation state or the close operation state; stopping, using a controller, operations of the left and right spindle motors and outputting an alarm if an error count is equal to or greater than a predetermined error limitation value as a result of the measurement of the Hall effect count of the left spindle motor and the Hall effect count of the right spindle motor, wherein the controller is operably connected to the first and second Hall sensors and the first and second spindle motors, the controller receiving Hall effect counts from the first and second Hall sensors; stopping, using the controller, operations of the left and right spindle motors and outputting an alarm if a difference of the Hall effect count obtained by comparing the Hall effect count of the left spindle motor and the Hall effect count of the right spindle motor is equal to or greater than a first predetermined limitation value; performing, using the controller, a synchronization procedure between the left and right spindles if the difference of the Hall effect count is smaller than the first limitation value and is equal to or greater than a second predetermined limitation value, the synchronization procedure changing an output ratio of at least one of the first and second spindle motors; and maintaining, using the controller, a current output ratio between the left and right spindle motors if the difference of the Hall effect count is smaller than the second limitation value.
