Abstract

A system for controlling a compactor machine can include a first GPS receiver on one side of a screed of a paver machine and a second GPS receiver on a second side of the screed, the first and second GPS receivers configured to communicate location information of the first and second sides of the screed, respectively, to a compactor machine; and a controller configured to receive the location information from screed and define a pass pattern for the compactor machine in view of the location information.

First claim

What is claimed is:

1. A system for controlling a compactor machine, comprising:
a first GPS receiver on one side of a screed of a paver machine and a second GPS receiver on a second side of the screed, the first and second GPS receivers configured to communicate location information of the first and second sides of the screed, respectively, to a compactor machine;
a temperature sensor on the screed, the temperature sensor configured to determine a positional temperature of an asphalt mat passed over by the screed; and
a controller configured to receive the location information from the first and the second GPS receivers on the screed and to receive the positional temperature from the temperature sensor and configured to define a pass pattern for the compactor machine in view of the location information and the positional temperature.

2. The system of claim 1 , wherein the compactor machine includes an auto steer system.

3. The system of claim 1 , wherein the positional temperature includes time-stamped and location-stamped temperature information of the asphalt mat and the controller is configured to determine a proper window of time for compacting the asphalt mat in view of the time-stamped and location-stamped information.

4. The system of claim 1 , wherein the location information is communicated to a compactor train including a plurality of compactor machines.

5. The system of claim 1 , wherein the location information is sent to a central server and then communicated to the compactor machine.

6. The system of claim 1 , wherein the compactor machine includes an autonomous or semi-autonomous compactor machine.

7. The system of claim 1 , wherein a controller on the compactor machine operates a steering of the compactor machine and plans a compaction route in view of the location information.

8. The system of claim 1 , wherein the first and second GPS receivers are RTK enabled GPS receivers.

9. A compactor machine comprising:
a frame;
one or more drums attached to the frame; and
a controller configured to provide an auto-steering capability for the compactor machine, the controller further configured to receive information from a corresponding paver machine regarding a location and outer boundaries of an asphalt mat laid down by the paver machine and to receive a positional temperature of the asphalt mat from the paver machine, wherein the controller is configured to plan a compaction route for the compactor machine based on the location information and the positional temperature received from the paver machine.

10. The compactor machine of claim 9 , wherein the positional temperature includes time-stamped and location-stamped temperature information of the asphalt mat and the controller is configured to determine a proper window of time for compacting the asphalt mat in view of the time-stamped and location-stamped temperature information.

11. The compactor machine of claim 9 , wherein the compactor machine includes an autonomous compactor machine.

12. The compactor machine of claim 9 , wherein the compactor machine is one of a plurality of compactor machines in a compaction train.

13. A method for controlling a compactor machine, comprising:
sending location information to a controller of the compactor machine regarding a location of an outer boundaries of an asphalt mat;
sending a positional temperature of the asphalt mat to the controller; and
planning a compaction route for the compactor machine in view of the location of the outer boundaries and the positional temperature of the asphalt mat.

14. The method of claim 13 , where sending information includes sending information from a first GPS receiver on one side of a screed and a second GPS receiver on a second side of the screed.

15. The method of claim 14 , wherein the first and second GPS receivers are RTK enabled GPS receivers.

16. The method of claim 13 , wherein planning the compaction route includes defining a pass pattern for the compactor machine.

17. The method of claim 13 , wherein the compactor machine includes an auto steer system and planning the compaction route includes providing steering instructions to the steering system.

18. The method of claim 13 , wherein the positional temperature includes time-stamped and location-stamped temperature information of the asphalt mat.

19. The method of claim 18 , further including controlling the compactor machine to compact the asphalt mat within a pre-determined window of time based on the positional temperature of the asphalt mat.

20. The method of claim 13 , including sending the location information to a compactor train including a plurality of compactor machines.
