ABSTRACT:
A user-operated system for interactive vehicle door opening and closing. The system detects vehicle position (gravity) and external force (such as wind) and provides an assistive force in effortlessly opening or closing the door. In some embodiments, the system provides a fail safe mode of operation in case of power failure and/or limit stops to minimize or prevent damage to external objects in the event the door is inadvertently brought into contact with the external object.
