A vehicle, method, and track control system for sensing the temperature of a track and controlling the vehicle's speed based on the temperature of the track. The track temperature may be sensed by a sensor embedded in a portion of the track, such as in a drive lug, a tread bar, or portion of the car
A vehicle, method, and track control system for sensing the temperature of a track and controlling the vehicle's speed based on the temperature of the track. The track temperature may be sensed by a sensor embedded in a portion of the track, such as in a drive lug, a tread bar, or portion of the carcass. The temperature of the track may also be used to alert an operator of a track temperature issue or request that the operator reduce the speed of the vehicle.

1. A work vehicle comprising: a load sensor;an engine;a drive train driven by the engine;a track system including at least one track, the track system connected to the drive train;a temperature sensor configured to sense a track temperature of the at least one track; anda vehicle control system configured to receive the track temperature and configured to control speed of the work vehicle based on the track temperature, wherein the at least one track comprises a carcass, a plurality of treads, and a plurality of lugs, and wherein the temperature sensor is positioned at least partially within at least one of the plurality of lugs or at least one of the plurality of treads, wherein the vehicle control system is configured to receive a vehicle load from the load sensor and wherein the vehicle control system controls the speed of the work vehicle based upon a combination of the track temperature sensed by the temperature sensor and the vehicle load sensed by the load sensor. 2. The work vehicle of claim 1, further comprising an operator alerting apparatus for alerting an operator of a speed condition or a track condition. 3. The work vehicle of claim 1, wherein the vehicle control system is configured to restrict the speed of the work vehicle based on the track temperature. 4. The work vehicle of claim 1, wherein the vehicle control system is configured to restrict the speed of the work vehicle below a maximum speed of the vehicle when the track temperature is approaching a maximum temperature of the at least one track. 5. The work vehicle of claim 1, wherein the temperature sensor is configured to wirelessly transmit the track temperature to a receiver, and wherein the receiver is communicatively connected to the vehicle control system. 6. The work vehicle of claim 1, wherein each of the at least one tracks includes a plurality of temperature sensors. 7. The work vehicle of claim 1, wherein the temperature sensor is embedded in one of the plurality of lugs of the track. 8. The work vehicle of claim 1, wherein the temperature sensor in one of the plurality of treads. 9. The work vehicle of claim 1, wherein the vehicle control system is configured to detect misalignment of the at least one track based upon the combination of the track temperature sensed by the temperature sensor and the load sensed by the load sensor. 10. The work vehicle of claim 1, wherein the temperature sensor is placed in a hotspot of the track, the hotspot of the track being empirically determined as a location in the track that is hottest during use of the track. 11. A method for controlling a work vehicle including at least one track, wherein the work vehicle is capable of traveling at a maximum speed, the method comprising: monitoring a track temperature of the at least one track;restricting the speed of the work vehicle to a restricted speed based on the track temperature, wherein the restricted speed is less than the maximum speed;determining that the at least one track is misaligned, wherein the determining that the at least one track is misaligned is based upon a combination of a sensed vehicle load and the track temperature being monitored; andproviding an alert to an operator of the vehicle that the at least one track is misaligned. 12. The method of claim 11, further comprising: determining if the track temperature is approaching a failure limit based on the track temperature and restricting the speed of the work vehicle based on the determination. 13. The method of claim 11, further comprising: removing the speed restriction when the track temperature decreases. 14. A vehicle control system configured to perform the method of claim 11. 15. A track system for a work vehicle, the track system comprising: a load sensor to sense a vehicle load; a track;a track temperature sensor configured to sense a track temperature of the track; anda controller connected to the track temperature sensor, wherein the controller is configured to detect misalignment of the track based upon a combination of the track temperature sensed by the track temperature sensor and the vehicle load sensed by the load sensor. 16. The track system of claim 15, wherein the controller is to restrict a speed of the work vehicle based upon the track temperature sensed by the track temperature sensor. 17. The track system of claim 16, wherein the controller is to output a misalignment warning prior to restricting the speed of the work vehicle based upon the track temperature sensed by the track temperature sensor.
