Abstract: A method of controlling a change in net axle torque on a vehicle comprises receiving a request for a desired net axle torque that is different than a current net axle torque, determining whether a lash zone exists between the current net axle torque and the desired net axle torque, determining a progression of constant rates of change of the front axle torque and a progression of constant rates of change of the rear axle torque that will result in a constant rate of change of the net axle torque from the current net axle torque to the desired net axle torque, and commanding the progression of constant rates of change of the front axle torque and the progression of constant rates of change of the rear axle torque if the lash zone exists between the current net axle torque and the desired net axle torque.
