Abstract
A vehicle includes a primary axle powered by an actuator and a secondary axle powered by a motor. The secondary axle includes a differential, first and second halfshafts, first and second wheels, a first electric clutch selectively coupling the first wheel to the first halfshaft, and a second electric clutch selectively coupling the second wheel to the second halfshaft. A vehicle controller is programmed to: responsive to a request to activate the secondary axle and a first speed difference between the first and second wheels being less than a first threshold, engage the first and second clutches at a same time, and, in response to the request to activate the secondary axle and the first speed difference between the first and second wheels exceeding the first threshold, engage one of the clutches and then subsequently engage the other of the clutches once the one of the clutches is fully engaged.
