Abstract
A vehicle includes a first axle, second axle, first clutch, second clutch, and controller. The first and second axles are coupled by a driveshaft. The first and second clutches are configured to isolate the driveshaft from loads transferred through the first and second axles, respectively, when open. The controller is programmed to, in response to a difference between output speeds of the first and second axles exceeding a first threshold, close the second clutch, reduce the difference such that it is below a second threshold, and close the first clutch.
