ABSTRACT:
In a vehicle powertrain that continually transmits power to a first set of vehicle wheels and selectively transmits power through a clutch to a second set of vehicle wheels, a method for controlling the clutch includes determining that brakes for slowing the vehicle wheels are applied and that an accelerator pedal of the vehicle is depressed less than a reference magnitude, determining that the rate of change of the average front wheel speed is greater than the rate of change of the average rear wheel speed, and setting the torque capacity of the clutch to a target magnitude.
