1. A method of controlling torque on a wheel axle comprising:

  • comparing at least one torque intervention request to a predetermined minimum axle torque for a current vehicle speed and a current direction of motion of the vehicle;

    wherein the predetermined minimum axle torque decreases as vehicle speed in an operator-selected direction of motion increases;

    calculating via a controller an arbitrated axle torque based on an operator-requested axle torque, the current vehicle speed, the current direction of motion, and the greater of said at least one torque intervention request and the predetermined minimum axle torque; and

    applying axle torque to the wheel axle based at least partially on the arbitrated axle torque.
