Abstract

A track system of a vehicle can be monitored (e.g., during operation of the vehicle) to obtain information about the track system which can be used for various purposes, such as, for example, to convey the information about the track system to a user (e.g., an operator of the vehicle) and/or to control the vehicle, for instance, by controlling a speed of the vehicle depending on a state (e.g., a temperature and/or one or more other physical characteristics) of the track system. This may be useful, for example, to gain knowledge about a track of the track system, to help prevent rapid wear or other deterioration of the track of the track system (e.g., blowout), and/or to adapt how fast or slow the vehicle moves in order to protect the track of the track system while permitting the speed of the vehicle to be greater over short periods (e.g., when travelling on or crossing roads or other particular areas).

First claim

The invention claimed is:

1. A track system for traction of a vehicle on a ground, the track system comprising:
a track that is elastomeric and comprises a ground-engaging outer surface and an inner surface opposite to the ground-engaging outer surface; and
a plurality of wheels configured to move the track around the wheels;
wherein at least one of the track and the plurality of wheels comprises a sensor configured to issue a signal processable to assess alignment of the track.

2. The track system of claim 1 , wherein a given one of the plurality of wheels comprises the sensor.

3. The track system of claim 2 , wherein: the plurality of wheels include a drive wheel configured to drive the track, an idler wheel configured to guide the track, and roller wheels configured to roll on a bottom run of the track; and the given one of the wheels is a given one of the roller wheels.

4. The track system of claim 1 , wherein: the sensor is a first sensor; the track system comprises a second sensor configured to issue a signal processable to assess the alignment of the track; and the alignment of the track is assessable based on the signal of the first sensor and the signal of the second sensor.

5. The track system of claim 4 , wherein: a first one of the plurality of wheels comprises the first sensor; and a second one of the plurality of wheels comprises the second sensor.

6. The track system of claim 5 , wherein: the wheels include a drive wheel configured to drive the track, an idler wheel configured to drive the track, and roller wheels configured to roll on a bottom run of the track; the first one of the wheels is a first one of the roller wheels; and the second one of the wheels is a second one of the roller wheels.

7. The track system of claim 1 , wherein the track comprises the sensor.

8. The track system of claim 7 , wherein: the track comprises a plurality of projections projecting from a given one of the ground-engaging outer surface and the inner surface; and at least part of the sensor is located in a given one of the projections.

9. The track system of claim 1 , wherein the sensor is a temperature sensor configured to sense a temperature of the track system.

10. The track system of claim 9 , wherein the temperature of the track system is a temperature of the track.

11. The track system of claim 9 , wherein the temperature of the track system is a temperature of a given one of the wheels.

12. The track system of claim 1 , wherein the sensor comprises a wireless transmitter configured to wirelessly issue the signal.

13. The track system of claim 1 , wherein the signal of the sensor is processable to perform an action based on the alignment of the track.

14. The track system of claim 13 , wherein the action comprises causing a communication device to communicate information regarding the alignment of the track to a user of the communication device.

15. The track system of claim 14 , wherein the communication device comprises a display for displaying the information regarding the alignment of the track.

16. The track system of claim 14 , wherein the information regarding the alignment of the track includes an indication that the track is misaligned.

17. The track system of claim 14 , wherein the communication device is part of a user interface of an operator cabin of the vehicle.

18. The track system of claim 1 , wherein the signal of the sensor is processable to determine that the track is misaligned.

19. A vehicle comprising the track system of claim 1 .

20. A monitoring system for monitoring a track system for traction of a vehicle on a ground, the track system comprising: a track that is elastomeric and comprises a ground-engaging outer surface and an inner surface opposite to the ground-engaging outer surface; and a plurality of wheels configured to move the track around the wheels, the monitoring system comprising:
a sensor configured to be part of at least one of the track and the plurality of wheels; and
a processing apparatus configured to assess alignment of the track based on output of the sensor.

21. A non-transitory computer-readable storage medium storing a program executable by a processing apparatus for use in respect of a vehicle comprising a track system for traction of the vehicle on a ground, the track system comprising: a track that is elastomeric and comprises a ground-engaging outer surface and an inner surface opposite to the ground-engaging outer surface; and a plurality of wheels configured to move the track around the wheels; the program comprising instructions executable by the processing apparatus to cause the processing apparatus to:
receive data derived from a sensor of the at least one of the track and the plurality of wheels; and
issue a signal regarding alignment of the track based on the data derived from the sensor.

22. A track for traction of a vehicle on a ground, the track being elastomeric and movable around a plurality of wheels, the track comprising:
a ground-engaging outer surface;
an inner surface opposite to the ground-engaging outer surface; and
a sensor configured to issue a signal processable to assess alignment of the track.

23. A wheel for a track system for traction of a vehicle on a ground, the track system comprising a track that is elastomeric, comprises a ground-engaging outer surface and an inner surface opposite to the ground-engaging outer surface, and is movable around the wheel and other wheels, the wheel comprising a sensor configured to issue a signal processable to assess alignment of the track.
