Method and apparatus of active dampening a powered closure system

摘要

An actuator for moving a closure between an open and a closed position. The actuator having a first mode, where the closure is free to move with respect to a closure frame, and a second mode where the actuator resists movement between the closure and the closure frame.

1. An actuator extending between a closure and a closure frame, where the actuator is operable to move the closure between an open and a closed position, the actuator comprising:
a base member couplable to one of the closure and the closure frame; and a drive member coupled to and moveable with respect to the base member and couplable to the other of the closure and the closure frame, wherein the actuator is operable in a first power mode, where the actuator automatically moves the closure between the open and closed positions in response to a signal from the user, and a second, non-driven manual mode, where the actuator actively monitors the movement of the closure with respect to the closure frame and provides varying non-zero levels of active dampening based at least in part on the position of the closure with respect to the closure frame, the direction of travel of the closure, and the speed of the closure with respect to the closure frame while remaining in the second, non-driven manual mode, wherein in the second, non-driven manual mode, the varying non-zero levels of active dampening are provided over the entirety of an arc of movement defined between the open and closed positions.
