A method for controlling operation of a transfer case in a motor vehicle
driveline that includes by an engine controlled by a throttle having a
variable position, and a transmission driveably connected to the engine
for producing multiple ratios of the speed of a transmission input
relative to the speed of a transmission output. The transfer case
transmitting rotating power in response to an electric signal applied to
a clutch. The method includes determining that the engine throttle
position is less than a first reference throttle position during a period
of predetermined length; determining that a speed of the vehicle speed is
in a predetermined range; determining that the transmission is operating
in a speed ratio greater than a reference speed ratio; determining that
the engine throttle position is greater than a first reference throttle
position; and increasing the torque capacity of the clutch for a
predetermined period.
