Abstract

A method to reduce backlash in a drive train of a four-wheel drive vehicle, the method including receiving rotational parameters from sensors in the four-wheel drive vehicle, determining a torque reversal in the drive train based on the received rotational parameters and sending a command signal to initiate engagement of a clutch pack in a transfer case of the drive train responsive to the determination.
