1. A track vehicle comprising:
a frame;
a track subsystem comprising:
a first roller assembly including a first axle coupled to the frame and a rotatable first roller;
a second roller assembly including a second axle coupled to the frame and a rotatable second roller mounted for rotation with the second axle;
a track mounted for rotation about the first and second rollers to drive movement of the track vehicle over a surface; and
a sensor on the first roller that senses a load imparted on the track by the first roller, against the surface, and generates a sensor signal indicative of the sensed load:
one or more processors; and
a data store that stores a set of computer executable instructions that, when executed by the one or more processors, configure the one or more processors to:
estimate a temperature distribution across the width of the track by accessing a model of stresses experienced by compression and expression of the track as the track rotates.
