Abstract

An industrial vehicle includes an operator compartment, a steering control device mounted for access from a first selectable operator position located outside of the operator compartment, and a steering column supporting the steering control device. The steering control device configured to rotate about the steering column and provide steering control from the operator compartment in a second selectable operator position opposite the first selectable operator position.

Claims

1. A steering system, comprising:

a steering control device configured for access from a first operator position; and

a steering control mount that supports the steering control device, wherein the steering control device is configured to rotate about the steering control mount and to provide steering control from a second operator position opposite the first operator position, and wherein the steering control device provides an opposite rotational steering sense in the first operator position as compared with the second operator position.

2. The steering system of claim 1, wherein the steering control device comprises a steering wheel that is mounted to the steering control mount.

3. The steering system of claim 2, wherein the steering control device is configured to turn a steered tire in a same rotational direction as a steering wheel when the position of the steering control device is detected in the second operating position, and wherein the steering control device is configured to turn the steered tire in an opposite rotational direction as the steering wheel when the position of the steering control is detected in the first operating position.

4. The steering system of claim 3, wherein rotating the steering wheel located in the second operating position in a clockwise direction results in the steered tire being turned clockwise about a vertical axis, and wherein rotating the steering wheel located in the first operating position in the clockwise direction results in the steered tire being turned counterclockwise about the vertical axis.

5. The steering system of claim 1, wherein the first operator position is located outside of a vehicle operator compartment, and wherein the second operator position is located within the vehicle operator compartment.

6. The steering system of claim 1, wherein the first operator position is associated with an operator being located in a first location on a vehicle, and wherein the second operator position is associated with the operator being located in a second location on the vehicle.

7. The steering system of claim 6, wherein the first location is on an opposite side of the steering control mount as the second location.

8. The steering system of claim 1, wherein a maximum vehicle travel speed varies according to whether the steering control device is rotated for operation in the first operator position or the second operator position.

9. The steering system of claim 1, wherein the steering control mount comprises a steering wheel operable from the first operator position, and wherein the steering wheel is further operable from the second operator position located on an opposite side of the steering control mount as the first operator position.

10. An apparatus, comprising:

means for detecting a position of a steering control that is configured to provide a steering function of a vehicle in either of a first operating position or a second operating position, where the first operating position is oriented opposite that of the second operating position;

means for receiving a steering request;

means for steering a vehicle in a first rotational steering sense, in response to receiving the steering request, when the steering control is located in the first operating position; and

means for steering the vehicle in a second rotational steering sense, in response to receiving the steering request, when the steering control is located in the second operating position, wherein the second rotational steering sense is opposite the first rotational steering sense.

11. The apparatus of claim 10, further comprising means for limiting the vehicle to a different maximum travel speed that varies according to the detected position of the steering control.

12. The apparatus of claim 10, wherein the first operating position is associated with an operator walking behind or in front of the vehicle.

13. The apparatus of claim 12, wherein the second operating position is associated with the operator riding on the vehicle.

14. The apparatus of claim 10, wherein the first operating position is located at one end of the vehicle and is associated with a forward direction of travel facing the vehicle, and wherein the second operating position is associated with a reverse direction of travel facing the first operating position.

15. The apparatus of claim 10, wherein the first and second operating positions are substantially aligned along a longitudinal centerline of the vehicle.

16. The apparatus of claim 10, wherein said means for steering a vehicle in a first rotational steering sense comprise means for turning a steered tire in a same rotational direction as a steering wheel when the position of the steering control device is detected in the second operating position, and wherein said means for steering the vehicle in a second rotational steering sense comprises means for turning the steered tire in an opposite rotational direction as the steering wheel when the position of the steering control is detected in the first operating position.

17. The apparatus of claim 10, wherein the steering control comprises a steering wheel attached to a steering control mount, and wherein the steering wheel is configured to rotate between the first operating position and the second operating position.

18. A method, comprising:

detecting a position of a steering control that is configured to provide a steering function of a vehicle in either of a first operating position or a second operating position, where the first operating position is oriented opposite that of the second operating position;

receiving a steering request;

steering a vehicle in a first rotational steering sense, in response to receiving the steering request, when the steering control is located in the first operating position; and

steering the vehicle in a second rotational steering sense, in response to receiving the steering request, when the steering control is located in the second operating position, wherein the second rotational steering sense is opposite the first rotational steering sense.

19. The method of claim 18, wherein the steering control is attached to a steering control mount, and wherein the steering control is configured to rotate between the first operating position and the second operating position.

20. The method of claim 19, wherein the steering control mount comprises a steering wheel operable from the first operating position, and wherein the steering wheel is further operable from the second operating position located on an opposite side of the steering control mount as the first operating position.
