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.
