Abstract:
1. A powered door system for enabling passenger ingress and egress through an aperture of a vehicle operating on at least one terrain attitude, said powered door system comprising: (a) at least one door adapted for movement in a first direction to at least partially uncover such aperture and in a second direction to at least partially cover such aperture; (b) at least one door support member disposed adjacent such aperture and connected to said at least one door with at least one door guide, said at least one door support member enabling movement of said at least one door in said first and said second directions; (c) a door drive means disposed adjacent such aperture for driving said at least one door, said door drive means including a drive member rigidly attached to one of such vehicle and a base member attached to such vehicle, said drive member adapted to receive at least one level of a power supply means from a vehicle power supply source and generate a driving force, and at least one link means coupled to said drive member at one end and coupled to one of said door and said door support member for transferring said driving force to said at least one door; and (d) a door controller coupled to said door drive means and a vehicle controller for receiving at least one door command signal, said door controller including at least one attitude sensor means for measuring at least one terrain attitude and providing at least one attitude proportional signal, a processor coupled to said at least one attitude sensor means for receiving said at least one attitude proportional signal and for providing at least one proportional drive signal, and a driver means connected to said processor for receiving said at least one proportional drive signal and for providing at least one control output signal of a predetermined value to such door drive means enabling incremental proportional adjustment of said driving force.
