Abstract

A vehicle simulation system may include: a platform positioned within a three-dimensional workspace, at least six upper support members positioned outside the three-dimensional workspace, at least six upper adjustable cables routed from corresponding upper support members and secured to the platform to apply at least a portion of upward tension to the platform, and a vehicle secured to the platform. The vehicle may provide one or more occupants with a simulated experience within a three-dimensional virtual environment as the upper adjustable cables are adjustably extended and retracted in a coordinated fashion to maneuver the platform.

Claims

1. A vehicle simulation apparatus, including:

a platform positioned within a three-dimensional workspace;

at least six upper support members positioned outside the three-dimensional workspace;

at least six upper adjustable cables routed from corresponding upper support members and secured to the platform to apply at least a portion of upward tension to the platform, wherein the upper adjustable cables are adjustably extended and retracted in a coordinated fashion to maneuver the platform; and

a vehicle secured to the platform to provide one or more occupants with a simulated experience within a three-dimensional virtual environment during the maneuvering.

2. The vehicle simulation apparatus of claim 1 wherein the upper adjustable cables are routed from the upper support members and secured to the platform in a manner that generally limits rotation of the platform during the maneuvering.

3. The vehicle simulation apparatus of claim 1 wherein the upper support members are arranged in pairs and first and second upper support members of each upper support member pair are generally horizontally spaced from each other.

4. The vehicle simulation apparatus of claim 3, further including:

a fourth upper support member pair positioned outside the three-dimensional workspace, wherein the upper support member pairs are spaced around the outside of the three-dimensional workspace in a generally rectangular pattern.

5. The vehicle simulation apparatus of claim 4 wherein the upper support member pairs are spaced around the outside of the three-dimensional workspace in a generally square pattern.

6. The vehicle simulation apparatus of claim 1, further including:

at least three lower support members positioned outside the three-dimensional workspace;

at least three lower adjustable cables routed from corresponding lower support members and secured to the platform to apply at least a portion of downward tension to the platform, wherein the upper and lower adjustable cables are adjustably extended and retracted in a coordinated fashion to maneuver the platform.

7. The vehicle simulation apparatus of claim 1, further including:

a gravity offload device secured to at least one of the platform and the vehicle to apply at least a portion of upward tension to at least one of the platform and the vehicle during the maneuvering.

8. The vehicle simulation apparatus of claim 1, further including:

a projection screen positioned such that an image displayed on the projection screen during the simulated experience is within view of at least one occupant of the vehicle.

9. The vehicle simulation apparatus of claim 7, the vehicle further including:

at least one input device disposed within the vehicle and accessible to at least one occupant of the vehicle to permit the at least one occupant to interactively control simulated movement of the vehicle within the three-dimensional virtual environment during the simulated experience.

10. A vehicle simulation apparatus, including:

a platform positioned and maneuvered within a three-dimensional workspace;

at least three pairs of upper support members positioned outside the three-dimensional workspace;

at least three pairs of upper adjustable cables routed from corresponding pairs of upper support members and releasably secured to the platform to apply at least a portion of upward tension to the platform, wherein the upper adjustable cables are adjustably extended and retracted in a coordinated fashion to maneuver the platform within the three-dimensional workspace; and

a vehicle releasably secured to the platform to provide one or more occupants with a simulated experience within a three-dimensional virtual environment during the maneuvering.

11. The vehicle simulation apparatus of claim 10, further including:

at least three lower support members positioned outside the three-dimensional workspace;

at least three lower adjustable cables routed from corresponding lower support members and releasably secured to the platform to apply at least a portion of downward tension to the platform, wherein the upper and lower adjustable cables are adjustably extended and retracted in a coordinated fashion during the maneuvering.

12. The vehicle simulation apparatus of claim 11 wherein the lower adjustable cables are routed from the lower support members and releasably secured to the platform to generally limit rotation of the platform during the maneuvering.

13. The vehicle simulation apparatus of claim 10, further including:

a gravity offload device releasably secured to at least one of the platform and the vehicle to apply at least a portion of upward tension to at least one of the platform and the vehicle during the maneuvering, wherein the gravity offload device reduces the load on the upper adjustable cables from at least one of the platform and the vehicle due to gravitational forces at least during the maneuvering.

14. The vehicle simulation apparatus of claim 10, further including:

a projection screen positioned such that an image displayed on the projection screen during the simulated experience is within view of at least one occupant of the vehicle, wherein the displayed image is based at least in part on a simulated position of the vehicle within the three-dimensional virtual environment during the simulated experience and adjusted in a coordinated fashion in conjunction during the maneuvering of the platform within the three-dimensional workspace.

15. The vehicle simulation apparatus of claim 14, the vehicle further including:

at least one input device disposed within the vehicle and accessible to at least one occupant of the vehicle to permit the at least one occupant to interactively control simulated movement of the vehicle within the three-dimensional virtual environment during the simulated experience, wherein the maneuvering of the platform and the image displayed on the projection screen is based at least in part on the at least one occupant interacting with the at least one input device.

16. A method of providing a vehicle simulation, including:

a) maneuvering a platform within a three-dimensional workspace by adjustably extending and retracting at least three pairs of upper adjustable cables in a coordinated fashion to apply at least a portion of upward tension to the platform, wherein the upper adjustable cable pairs are routed from corresponding pairs of upper support members disposed outside the three-dimensional workspace and releasably secured to the platform; and

18. The method of claim 16, further including:

c) applying at least a portion of upward tension from a gravity offload device to at least one of the platform and the vehicle to reduce the load on the upper adjustable cables from at least one of the platform and the vehicle due to gravitational forces at least during the maneuvering in a), wherein the gravity offload device is releasably secured to at least one of the platform and the vehicle.
