Abstract

A method for automatically controlling vehicle speeds of a track-based work vehicle may generally include receiving, with a computing device, one or more signals associated with an operating temperature for a track component of a track assembly of the track-based work vehicle, comparing, with the computing device, the operating temperature for the track component to a predetermined temperature threshold defined for the track component and automatically limiting, with the computing device, a vehicle speed of the track-based work vehicle when the operating temperature for the track component exceeds the predetermined temperature threshold.

First claim

What is claimed is:

1. A system for automatically controlling vehicle speeds of a track-based work vehicle, the system comprising:
a track assembly including a track, a drive wheel configured to rotationally drive the track and at least one secondary wheel configured to engage the track;
a controller including one or more processors and associated memory, the memory storing instructions that, when implemented by the one or more processors, configure the controller to:
receive one or more signals associated with an operating temperature for at least one of the track or the at least one secondary wheel;
compare the operating temperature to a predetermined temperature threshold defined for the at least one of the track or the at least one secondary wheel; and
automatically limit a vehicle speed of the track-based work vehicle when the operating temperature exceeds the predetermined temperature threshold.

2. The system of claim 1 , wherein the at least one secondary wheel corresponds to a roller wheel of the track assembly.

3. The system of claim 1 , further comprising a temperature sensor configured to monitor the operating temperature for the at least one of the track or the at least one secondary wheel, the controller being configured to receive the one or more signals from the temperature sensor.

4. The system of claim 1 , wherein the one or more signals are associated with one or more monitored vehicle parameters that provide an indication of the operating temperature for the at least one of the track or the at least one secondary wheel, wherein the controller is further configured to predict the operating temperature for the at least one of the track or the at least one secondary wheel based on the one or more monitored vehicle parameters.

5. The system of claim 4 , wherein the one or more monitored vehicle parameters are associated with a load on the track, a current vehicle speed for the track-based work vehicle and a time at which the track-based work vehicle has been operating at the current vehicle speed.

6. The system of claim 1 , wherein the controller is configured to automatically downshift a transmission of the track-based work vehicle or automatically adjust an output speed of an engine of the track-based work vehicle when the operating temperature for the track component exceeds the predetermined temperature threshold.

7. The system of claim 1 , wherein the controller is configured to automatically limit the vehicle speed of the track-based work vehicle to a first maximum speed limit when the operating temperature exceeds the predetermined temperature threshold.

8. The system of claim 7 , wherein the controller is further configured to:
determine that the operating temperature for the track component has exceeded the predetermined temperature threshold for a given period of time; and
automatically limit the vehicle speed of the track-based work vehicle to a second maximum speed limit, wherein the second maximum speed limit is less than the first maximum speed limit.

9. The system of claim 7 , wherein the predetermined temperature threshold corresponds to a first predetermined temperature threshold, wherein the controller is further configured to:
compare the operating temperature to a second predetermined temperature threshold defined for the at least one of the track or the at least one secondary wheel, wherein the second predetermined temperature threshold is greater than the first predetermined temperature threshold; and
automatically limit the vehicle speed of the track-based work vehicle to a second maximum speed limit when the operating temperature exceeds the second predetermined temperature threshold, wherein the second maximum speed limit is less than the first maximum speed limit.

10. The system of claim 1 , wherein the controller is further configured to provide a notification to an operator of the track-based work vehicle when the operating temperature exceeds an initial predetermined temperature threshold, the initial predetermined temperature threshold being less than the predetermined temperature threshold.
