Abstract

Claims (51)

1. A method of operating a vehicle, the vehicle including a ballast and a ballast actuator that is configured to reposition the ballast, the method comprising:

receiving at least one of:

(a) load data indicating a torque on an axle assembly of the vehicle;

(b) an indication of a type of an implement that is coupled to the vehicle; or

(c) a selection by an operator of an operating mode for the vehicle from a list of operating modes; and

controlling the ballast actuator to reposition the ballast based on at least one of (a) the load data, (b) the indication of the type of the implement, or (c) the selection by the operator.

2. The method of claim 1 , wherein the method comprises:

receiving the load data indicating the torque on the axle assembly of the vehicle; and

controlling the ballast actuator to reposition the ballast based on the load data.

3. The method of claim 2 , wherein the load data is first load data and the axle assembly is a first axle assembly, and wherein the method comprises:

receiving second load data indicating a torque on a second axle assembly of the vehicle; and

controlling the ballast actuator to reposition the ballast based on the first load data and the second load data.

4. The method of claim 3 , wherein the method comprises:

comparing the first load data and the second load data;

determining a desired position of the ballast based on the comparison of the first load data and the second load data; and

controlling the ballast actuator to reposition the ballast to the desired position.

5. The method of claim 1 , wherein the method comprises:

receiving the indication of the type of the implement that is coupled to the vehicle; and

controlling the ballast actuator to reposition the ballast based on the indication of the type of the implement.

6. The method of claim 5 , wherein the indication of the type of the implement is a signal from an implement sensor that interacts with an identifier of the implement.

7. The method of claim 5 , wherein the indication of the type of the implement is an input by the operator through an operator interface.

8. The method of claim 1 , wherein the method comprises:

receiving the selection by the operator of the operating mode for the vehicle from the list of operating modes; and

controlling the ballast actuator to reposition the ballast based on the selection by the operator.

9. The method of claim 8 , wherein the method comprises:

controlling an operator interface to provide the list of operating modes to the operator; and

receiving the selection through the operator interface.

10. The method of claim 9 , wherein the method comprises:

receiving an indication of a current capability of the vehicle; and

generating the list of operating modes for the vehicle based on the indication of the current capability of the vehicle.

11. The method of claim 1 , wherein the method comprises:

receiving ballast position data from a ballast position sensor, the ballast position data indicating a current position of the ballast; and

controlling the ballast actuator to reposition the ballast based on the ballast position data.

12. The method of claim 1 , wherein controlling the ballast actuator to reposition the ballast shifts a center of gravity of the vehicle relative to the axle assembly of the vehicle.

13. A method of operating a vehicle, the method comprising:

receiving, from a load sensor, load data related to a load on an axle assembly of the vehicle;

determining, based on the load data, a desired position of a ballast; and

determining whether the ballast is capable of moving to the desired position without the ballast extending beyond a predetermined range of positions.

14. The method of claim 13 , the method comprising:

in response to a determination that the ballast is capable of moving to the desired position without the ballast extending beyond the predetermined range of positions, controlling a ballast actuator to move the ballast to the desired position.

15. The method of claim 14 , wherein the predetermined range of positions is based on a range of motion of the ballast actuator.

16. The method of claim 13 , the method comprising:

in response to a determination that the ballast is not capable of moving to the desired position without the ballast extending beyond the predetermined range of positions, providing a notification indicating that at least one of (a) weight should be added to the ballast or (b) weight should be removed from the ballast.

17. The method of claim 13 , wherein the method comprises:

determining, based on the load data, that the desired position of the ballast would shift a center of gravity of the vehicle to a desired range of positions.

18. The method of claim 13 , wherein the load sensor is a force sensor, and wherein the load data indicates a downward force on the axle assembly.

19. The method of claim 13 , wherein the load sensor is a torque sensor, and wherein the load data indicates a torque on the axle assembly.

20. A method of operating a vehicle, comprising:

receiving a request to shift a center of gravity of the vehicle; and

in response to receiving the request, controlling a ballast actuator to move fuel between a first tank and a second tank,

wherein the first tank is fluidly coupled to an engine of the vehicle.
