Abstract
A system for controlling a transfer case clutch assembly is provided and is deployed within a four-wheel drive vehicle having a front driveshaft , a rear driveshaft , and a transfer case which selectively provides torque to the driveshafts by way of a clutch assembly . System includes a controller which is communicatively coupled to the clutch assembly . Controller receives signals generated by sensors , utilizes the received signals to determine the onset of a slip condition, and based upon this determination, generates a command signal to selectively activate the clutch assembly effective to smoothly release torque from the front driveshaft and/or rear driveshaft
