Abstract:
A control method of sliding a vehicle door by a powered sliding device having a clutch mechanism, wherein said clutch mechanism is switched to a first coupled state for transmitting a door-closing rotation of a motor to a wire drum when the motor is rotated in a door-closing direction, and is switched to a second coupled state for transmitting a door-opening rotation of the motor to the wire drum when the motor is rotated in a door-opening direction, and is switched to a first brake state for transmitting a door-closing rotation of the wire drum to the motor when the wire drum is relatively rotated in a door-closing direction with respect to the motor in the first coupled state, and is switched to a second brake state for transmitting a door-opening rotation of the wire drum to the motor when the wire drum is relatively rotated in a door-opening direction with respect to the motor in the second coupled state, and is switched to an uncoupled state when the motor is rotated in the door-opening direction in the first coupled state or the motor is rotated in the door-closing direction in the second coupled state, and is returned to the uncoupled state when the wire drum is rotated in the door-opening direction in the first brake state or the wire drum is rotated in the door-closing direction in the second brake state; said method comprising:stopping the motor in a state that the rotation of said wire drum is restricted by an auxiliary brake when said slide door reaches at a desired semi-open position between a door-open position and a door-closed position; releasing restriction of said wire drum by said auxiliary brake when a predetermined time has elapsed.
