Tire size calibration and control system

Abstract:

A mobile machine includes a plurality of ground-engaging elements that each include a tire, and a plurality of motors, one motor coupled to each of the plurality of ground-engaging elements configured to drive movement of the plurality of ground-engaging elements. The mobile machine also includes a speed sensor coupled to each motor configured to generate speed signals indicative of an operating speed of each motor. The mobile machine includes a tire calibration system configured to receive the speed signals from each speed sensor and to identify a tire size differential across the plurality of ground-engaging elements based on the speed signals. The mobile machine includes a control system configured to generate a separate control signal for each of the plurality of motors based on the tire size differential.
