Abstract
An automated door system includes a door pivotally coupled to a vehicle body at a hinge axis defined by at least one hinge assembly. A power assist device is coupled to the hinge assembly and further coupled to the door. The power assist device is configured to slow movement of the door along a door swing path from an initial velocity to a slow close velocity when the initial velocity exceeds a predetermined threshold velocity, thereby providing a slow and controlled close when a user attempts to slam the door. The power assist device is further configured to power opening and closing movement of the door as initiated by a user.
