Methods and systems are provided for selectively engaging an electric machine to an electric axle of a vehicle. In one example, a method may include engaging or disengaging the electric machine to a differential of the electric-axle by adjusting pressure in a piston coupled to an axle shaft of the electric-axle via a disconnect clutch.
