Abstract

A slippage condition response system for a first machine of a plurality of machines is disclosed. The response system may have a sensing system configured to sense a parameter indicative of a slippage condition of the first machine. Additionally, the response system may have a locator configured to sense a parameter indicative of a location of the first machine. The response system may also have a transmitter. In addition, the response system may have a controller, which may be in communication with the sensing system, the locator, and the transmitter. The controller may be configured to monitor the location of the first machine. The controller may also be configured to monitor the parameter indicative of a slippage condition of the first machine. Additionally, the controller may be configured to transmit to an offboard system at least one location where the first machine experienced a slippage condition.

Claims

1. A method of operating a worksite, the method comprising:

monitoring a location of a first haul truck of a plurality of haul trucks located at a worksite;

monitoring a parameter indicative of a slippage condition of the first haul truck;

transmitting to an offboard system at least one location where the first haul truck experienced a slippage condition; and

dispatching a machine to repair the at least one slippage location at the worksite.

2. The method of claim 1, further including storing in a map at least one known slippage condition location where at least one of the plurality of haul trucks experienced a slippage condition.

3. The method of claim 1, wherein transmitting to the offboard system includes transmitting to a second machine of the plurality of haul trucks.

4. The method of claim 1, wherein transmitting to the offboard system includes transmitting to a worksite control facility.

5. The method of claim 1, further including:

receiving from the offboard system at least one known slippage condition location where at least one of the plurality of haul trucks experienced a slippage condition; and

autonomously controlling the first haul truck based on the at least one known slippage condition location.

6. The method of claim 5, wherein autonomously controlling the first haul truck includes re-routing the first haul truck.

7. The method of claim 1, further including:

receiving from the offboard system at least one known slippage condition location where at least one of the plurality of haul trucks experienced a slippage condition; and

warning an operator of the first haul truck of the at least one known slippage condition location.

8. A slippage condition response system for a first machine of a plurality of machines, the slippage condition response system comprising:

a sensing system configured to sense a parameter indicative of a slippage condition of the first machine;

a locator configured to sense a parameter indicative of a location of the first machine;

a transmitter;

a receiver;

a map; and

a controller in communication with the sensing system, the locator, the transmitter, the receiver, and the map, the controller being configured to;

monitor the location of the first machine;

monitor the parameter indicative of a slippage condition of the first machine;

transmit to an offboard system at least one location where the first machine experienced a slippage condition;

receive from the offboard system at least one known slippage condition location where at least one of the plurality of machines experienced a slippage condition;

store in the map the at least one known slippage condition location; and

autonomously control the first machine based on the at least one known slippage condition location.

9. The slippage condition response system of claim 8, wherein the locator is included in the sensing system.

10. The slippage condition response system of claim 8, wherein the controller is further configured to warn an operator of the first machine of the at least one known slippage condition location.

11. The slippage condition response system of claim 8, wherein the offboard system includes a worksite control facility.

12. The slippage condition response system of claim 8, wherein the offboard system includes a second machine of the plurality of machines.

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

monitoring a location of a first machine of a plurality of machines;

monitoring a parameter indicative of a slippage condition of the first machine;

transmitting to an offboard system at least one location where the first machine experienced a slippage condition;

receiving from the offboard system at least one known slippage condition location where at least one of the plurality of machines experienced a slippage condition;

storing in a map the at least one known slippage condition location; and

autonomously controlling the first machine based on the at least one known slippage condition location.

14. The method of claim 13, wherein autonomously controlling the first machine includes re-routing the first machine.

15. The method of claim 13, further including autonomously controlling a second machine of the plurality of machines based on the at least one known slippage condition location.

16. The method of claim 13, further including warning an operator of the first machine of the at least one known slippage condition location.

17. The method of claim 13, wherein transmitting to the offboard system includes transmitting to a second machine of the plurality of machines.

18. The method of claim 13, wherein transmitting to the offboard system includes transmitting to a worksite control facility.
