Abstract

A method of assembling a vehicle chassis includes providing a vehicle frame having a plurality of packaging cavities opening in a plurality of different directions, mounting vehicle hardware components toward openings in the packaging cavities and installing the vehicle hardware components into operative positions in their packaging cavities. The installation of the vehicle hardware components and their respective packaging cavities may be arranged to make the components removable from the frame in respective ones of the different directions.

12. The method of claim 1, further comprising:

positioning said frame in a first position;

installing at least one of said vehicle hardware components into operative position in its respective packaging cavity when said frame is in said first position;

rotating said frame to a second position; and

installing at least another of said vehicle hardware components into operative position in its respective packaging cavity when said frame is in its second position.

13. The method of claim 1, further comprising operatively connecting a vehicle floor to the frame to form a frame assembly having the vehicle floor overlaying at least some of the packaging cavities opening in at least one of the different directions.

14. The method of claim 13, further comprising operatively connecting a vehicle body to the frame assembly at the vehicle floor to at least partially define a passenger compartment.

15. The method of claim 13, further comprising:

providing vehicle body components including interior hardware, vehicle body frame structure and at least one vehicle body panel; and

operatively connecting the vehicle body components to the frame assembly at said vehicle floor.

16. The method of claim 15, wherein at least some of the vehicle body components are provided as a body module, the body module being preassembled before said operatively connecting.

17. The method of claim 1, wherein at least some of the vehicle hardware components are provided as a hardware module, the hardware module being preassembled before said mounting.

18. The method of claim 1, further comprising:

providing at least one bottom panel and

operatively connecting said at least one bottom panel to said frame from one of the different directions to at least partially close at least some of the packaging cavities.

19. The method of claim 1, including positioning said frame relative to the vehicle hardware components prior to mounting the vehicle hardware components toward respective openings in the respective packaging cavities.

20. The method of claim 19, wherein positioning the frame is accomplished by automated means.

21. The method of claim 20, wherein the automated means include a conveyor system.

22. The method of claim 20, wherein the automated means include an hydraulic lift.

23. The method of claim 1, including positioning the vehicle hardware components relative to said frame prior to mounting the vehicle hardware components toward respective openings in the respective packaging cavities.

24. The method of claim 23, wherein positioning the vehicle hardware components is accomplished by automated means.

25. The method of claim 24, wherein the automated means include a conveyor system.

26. The method of claim 24, wherein the automated means include an hydraulic lift.

27. A method of assembling a vehicle having a body and a chassis comprising:

providing structural elements formed into a frame having opposed frame faces;

mounting vehicle hardware components toward at least one of the frame faces from one direction to form a chassis, wherein the vehicle hardware components form at least two of a braking system that is responsive to nonmechanical control signals, a steering system that is responsive to nonmechanical control signals and an energy conversion system that is responsive to nonmechanical control signals; and

mounting vehicle body components toward the opposed frame face from another direction to form a vehicle.

28. The method of claim 27, wherein providing structural elements includes forming the opposed face of the frame as a floor for the body.
