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.

Abstract: A method is directed to controlling a differential within an active antilock brake system. The method provides for receiving a secondary axle wheel speed, receiving a vehicle speed, determining a difference value between the vehicle speed and the secondary axle wheel speed, and activating the differential responsive to the difference value. The step of activating the differential responsive to the difference value may include steps for comparing the difference value to a threshold value and activating the differential based on the comparison. The step of activating the differential based on the comparison may include steps for determining a differential request value based on the comparison, activating the differential responsive to the differential request value when the differential request value is less than a maximum differential request value, and activating the differential responsive to the maximum differential request value when the differential request value exceeds the maximum differential request value.

Abstract: The invention provides a method of progressive engagement of all-wheel drive for a mobile vehicle. A set of vehicle parameters is sensed, and an all-wheel drive lock value is determined based on the sensed set of vehicle parameters. Vehicle subsystem control activation is determined, and the all-wheel drive lock value is adjusted based on the vehicle subsystem control activation determination. An all-wheel drive controller is engaged based on the adjusted all-wheel drive lock value.
