First Claim
Patent Images
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; and
a 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.

Abstract
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.

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; and providing an alert to an operator of the vehicle that the at least one track is misaligned. - View Dependent Claims (12, 13, 14)

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; and a 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. - View Dependent Claims (16, 17)
