Abstract
A vehicle includes a primary axle powered by an actuator and a secondary axle powered by a motor and including a wheel and a clutch selectively coupling the wheel to the motor via mating components. A controller is electrically connected to the clutch and the motor. The controller is programmed to, in response to an engagement of the clutch being unsuccessful within a first duration of time, command a series of speeds to the motor based on wheel speed and an alternating offset that changes between positive and negative signs at predefined periods so that relative speeds between the mating components oscillate due to the alternating offset to jiggle the clutch into engagement.
