Abstract

A swing control assembly for a first machine is provided. The swing control assembly includes a position detection module configured to generate a signal indicative of a relative position of a second machine with respect to the first machine. The swing control assembly includes a controller communicably coupled to the position detection module. The controller is configured to receive the signal indicative of the relative position of the second machine with respect to the first machine. The controller is configured to determine a direction of swing associated with the first machine based on the received signal. The controller is configured to provide an instruction to initiate a swing operation of the first machine based on the determined direction of swing.

Claims

a position detection module configured to generate a signal indicative of a relative position of a second machine with respect to the first machine; and

a controller communicably coupled to the position detection module, the controller configured to;

receive the signal indicative of the relative position of the second machine with respect to the first machine;

determine a direction of swing associated with the first machine based on the received signal; and

provide an instruction to initiate a swing operation of the first machine based on the determined direction of swing.

2. The swing control assembly of claim 1, wherein the position detection module includes a position detection sensor provided on the second machine, the position detection sensor configured to generate a signal indicative of a current position of the second machine.

3. The swing control assembly of claim 2, wherein the position detection sensor includes at least one of a global positioning system, an accelerometer, and a gyroscope.

4. The swing control assembly of claim 1, wherein the position detection module includes a perception sensor provided on the first machine, the perception sensor configured to sense the relative position of the second machine with respect to the first machine.

5. The swing control assembly of claim 1, wherein the controller is communicably coupled to a machine control unit of the first machine, and wherein the controller is configured to provide the instruction to the machine control unit to automatically initiate the swing operation.

6. The swing control assembly of claim 1, wherein the controller is communicably coupled to an output unit, and wherein the controller is configured to provide the instruction to an operator through the output unit.

7. The swing control assembly of claim 1, wherein the controller is further configured to:

receive a signal indicative of a current mode of operation of the first machine;

determine if a loading operation is in progress by the first machine based on the received signal of the current mode of operation;

identify a current direction of swing of the first machine if the loading operation is in progress; and

provide the instruction to initiate a next swing operation of the first machine in a same direction as the current direction of swing.

8. The swing control assembly of claim 1, wherein the controller is further configured to:

receive a signal indicative of a current status of the second machine;

determine if the second machine is in a ready state based on the received signal of the current status;

determine the direction of swing of the first machine based on the relative position of the second machine with respect to the first machine and the ready state of the second machine; and

provide the instruction to initiate the swing operation of the first machine along the determined direction of swing.

9. The swing control assembly of claim 1, wherein the controller is further configured to:

determine if the first machine is performing a single-sided loading operation;

identify a current direction of swing of the first machine if the first machine is performing the single-sided loading operation; and

provide the instruction to initiate a next swing operation of the first machine in a same direction as the current direction of swing.

10. The swing control assembly of claim 1, wherein the controller is further configured to:

determine if the first machine is performing a double-sided loading operation;

identify a current direction of swing of the first machine if the first machine is performing the double-sided loading operation; and

provide the instruction to initiate a next swing operation of the first machine in an opposite direction from the current direction of swing.

11. A method for controlling a swing of a first machine, the method comprising:

receiving, by a controller, a signal indicative of a relative position of a second machine with respect to the first machine from a position detection module;

determining, by the controller, a direction of swing associated with the first machine based on the received signal; and

providing, by the controller, an instruction to initiate a swing operation of the first machine based on the determined direction of swing.

12. The method of claim 11 further comprising:

receiving, by the controller, a signal indicative of a current mode of operation of the first machine;

determining, by the controller, if a loading operation is in progress based on the received current mode of operation;

identifying, by the controller, a current direction of swing of the first machine if the loading operation is in progress; and

providing, by the controller, the instruction to initiate a next swing operation of the first machine in a same direction as the current direction of swing.

13. The method of claim 11 further comprising:

receiving, by the controller, a signal indicative of a current status of the second machine;

determining, by the controller, if the second machine is in a ready state based on the received current status;

determining, by the controller, the direction of swing of the first machine based on the relative position of the second machine with respect to the first machine and the ready state of the second machine; and

providing, by the controller, the instruction to initiate a next swing operation of the first machine along the determined direction of swing.

14. The method of claim 11 further comprising:

determining, by the controller, if the first machine is performing a single-sided loading operation;

identifying, by the controller, a current direction of swing of the first machine if the first machine is performing the single-sided loading operation; and

providing, by the controller, the instruction to initiate a next swing operation of the first machine in a same direction as the current direction of swing.

15. The method of claim 11 further comprising:

determining, by the controller, if the first machine is performing a double-sided loading operation;

identifying, by the controller, a current direction of swing of the first machine if the first machine is performing the double-sided loading operation; and

providing, by the controller, the instruction to initiate a next swing operation of the first machine in an opposite direction from the current direction of swing.

16. A machine comprising:

an engine; and

a swing control assembly comprising;

a position detection module configured to generate a signal indicative of a relative position of a second machine with respect to the machine; and

a controller communicably coupled to the position detection module, the controller configured to;

receive the signal indicative of the relative position of the second machine with respect to the machine;

determine a direction of swing associated with the machine based on the received signal; and

provide an instruction to initiate a swing operation based on the determined direction of swing.
