Abstract
A method of controlling an axle assembly includes providing an axle assembly in a first state. A first controller is provided in electrical communication with the axle assembly. The first controller determines if a source of power has an available amount of electrical energy that is within a predetermined range and a predetermined period of time has elapsed. If the available amount of electrical energy is within the predetermined range and the predetermined period of time has elapsed, then electrical energy is transferred from the source of power to an electric motor generator and an axle disconnect clutch is engaged to provide the axle assembly in another state.
