Abstract
A traction control system for a machine having two driven wheels is disclosed. Braking mechanisms controllably apply braking forces to each of the driven wheels. Transducers produce an actual speed signal having a value proportional to the rotational velocity of each driven wheel. A microprocessor produces a desired speed signal having a value representative of a desired rotational velocity of each driven wheel, and an error signal representative of the difference between the values of the desired and actual speed signals. The microprocessor additionally multiplies the error signal by a gain value and produces a braking command signal to the braking mechanism to apply braking forces to a slipping wheel. The present invention provides the advantage of modifying the gain value based on machine operating conditions in order to achieve good performance.
