1. An electronic traction control system for a work machine having a front frame, a rear frame, and an articulation joint connecting the front and rear frames, the system comprising:

  • an articulation sensor adapted to provide an articulation angle signal;

    at least two wheels, with each wheel adapted to provide a wheel speed signal;

    a brake associated with the work machine;

    an electronic control module adapted to receive the articulation angle and wheel speed signals;

    calculate an articulation rate responsive to the articulation angle signal;

    determine a desired wheel speed having at least one of;

    an articulation-caused linear velocity component calculated responsive to the articulation rate, articulation angle, and wheel speed signals, and a transient articulation-caused velocity component calculated responsive to the articulation rate, articulation angle, and wheel speed signals; and

    responsively produce a brake signal to control the brake.
