Abstract
A system and a method for controlling a hybrid vehicle powertrain during a change from a two-wheel drive mode to a four-wheel drive mode is provided. In response to a request to couple the second pair of wheels to the powertrain, a driveline controller commands an increased torque from the electric motor to be applied to the first pair of wheels The increased torque from the electric motor is based on an AWD engagement torque of the second pair of wheels to counteract an engagement torque of a second pair of drive wheels before changing from the two-wheel drive mode to the four-wheel drive mode.
