Abstract

A control system for a mobile machine includes one or more sensors for generating machine state data and one or more computing devices. The one or more computing devices are configured to determine a first segment and a second segment of an operating path of the machine and to use the machine state data to determine an optimal speed for a turn maneuver between the first segment and the second segment of the operating path. The one or more computing devices may further be configured to determine a first optimal speed for a first portion of the turn maneuver and a second optimal speed for a second portion of the turn maneuver.

Claims

1. A control system for a mobile machine, the control system comprising:

one or more sensors for generating machine state data; and

one or more computing devices configured to—

determine a first segment and a second segment of an operating path of the machine, the first segment and the second segment being consecutive segments of the operating path, and

use the machine state data to determine a first optimal speed for a first portion of a turn maneuver between the first segment and the second segment of the operating path and a second optimal speed for a second portion of the turn maneuver, the turn maneuver being a transition between the first segment and the second segment of the operating path and not forming a part of the operating path.

2. The control system as set forth in claim 1, the machine state data including data indicating a material fill level.

3. The control system as set forth in claim 1, the machine state data including data associated with the state of an implement associated with the mobile machine.

4. The control system as set forth in claim 3, the machine state data including data indicating the position of an implement mounted on the machine.

5. The control system as set forth in claim 1, the first optimal speed being based at least in part on a first turn radius and the second optimal speed being based at least in part on a second turn radius.

6. The control system as set forth in claim 1, the one or more computing devices further configured to adjust at least one of the optimal speeds of the mobile machine while the machine performs the turn maneuver.

7. The control system as set forth in claim 1, the one or more computing devices further configured to adjust at least one of the optimal speeds of the mobile machine while the machine performs the turn maneuver using sensed machine state data.

8. The control system as set forth in claim 7, the machine state data including an orientation of the machine.

9. A control system for a mobile machine, the control system comprising:

one or more computing devices configured to—

determine a first optimal speed for a first portion of a turn maneuver between a first segment and a second segment of an operating path and a second optimal speed for a second portion of the turn maneuver, the first segment and the second segment being consecutive segments of the operating path, and the turn maneuver being a transition between the first segment and the second segment of the operating path and not forming a part of the operating path,

guide the machine through the turn maneuver at the optimal speeds,

determine an adjusted optimal speed while guiding the machine through the turn maneuver, and

adjust the speed of the machine during the turn maneuver to match the adjusted optimal speed.

10. The control system as set forth in claim 9, further comprising one or more sensors for generating machine state data, wherein the one or more computing devices are further configured to adjust at least one of the optimal speeds while guiding the machine through the turn maneuver using the machine state data.

11. The control system as set forth in claim 10, the machine state data including data indicating an orientation of the machine.

12. The control system as set forth in claim 11, the orientation of the machine including a tilt of the machine.

13. The control system as set forth in claim 10, the machine state data including data indicating a position of an implement mounted on the machine.

14. The control system as set forth in claim 9, further comprising one or more sensors for generating state data relating to an implement pulled by the machine, wherein the one or more computing devices are further configured to adjust at least one of the optimal speeds while guiding the machine through the turn maneuver using the state data.

15. The control system as set forth in claim 14, the state data including data indicating an orientation of the implement.

16. The control system as set forth in claim 15, the orientation of the implement including a lateral tilt of the implement.

17. A control system for a mobile machine, the control system comprising:

one or more sensors for generating machine state data; and

one or more computing devices configured to—

determine a first segment and a second segment of an operating path of the machine, the first segment and the second segment being consecutive segments of the operating path,

determine a first optimal speed for a first portion of a turn maneuver between the first segment and the second segment of the operating path and a second optimal speed for a second portion of the turn maneuver, the optimal speed based at least in part on a state of the machine or a state of an implement pulled by the machine, the turn maneuver being a transition between the first segment and the second segment of the operating path and not forming a part of the operating path.

18. The control system as set forth in claim 17, the one or more computing devices configured to determine at least one of the optimal speeds for the turn maneuver based at least in part on an operating position of the implement pulled by the machine.

19. The control system a set forth in claim 17, the one or more computing devices configured to determine at least one of the optimal speeds for the turn maneuver based at least in part on a fill level of the implement pulled by the machine.
