ABSTRACT:
A method is directed to controlling a traction control system including a controllable center coupling and a controlled brake system. The method provides for receiving axle speed information, receiving a vehicle speed, determining at least one difference value between the vehicle speed and the axle speed information, and activating the controllable center coupling and the controlled brake system responsive to the difference values. The step of activating the controllable center coupling responsive to at least one of the difference values may include comparing the at least one difference value to at least one associated threshold value, and activating the controllable center coupling based on the comparison. The step of activating the controllable center coupling based on the comparison may include determining an engine torque request value based on the comparison, and engaging an engine with the controllable center coupling based on the engine torque request value.
