Abstract: A vehicle includes a first axle, second axle, driveshaft, engine, clutch, and controller. The first and second axles are coupled by the driveshaft. The engine is configured to generate torque in the first axle. The clutch is configured to disconnect an output of the second axle. The controller is programmed to, responsive to a clutch release request that would result in an increasing commanded torque to the first axle being greater than a threshold, decrease an engine torque such that a first axle torque is less than the threshold.

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.

Abstract: A vehicle includes a first axle, a second axle, a driveshaft, a first clutch, a second clutch, a third clutch, and a controller. The second axle has first and second half shafts. The second axle has first and second wheels. The driveshaft is disposed between the first and second axles and is coupled to the second axle. The first clutch is configured to selectively couple the driveshaft to the first axle. The second clutch is configured to selectively couple the first wheel to the first half shaft. The third clutch is configured to selectively couple the second wheel to the second half shaft. The controller is programmed to repeatedly connect the first axle to the second axle via the driveshaft by alternating between (i) closing the second clutch and then the first clutch and (ii) closing the third clutch and then the first clutch.

Abstract: A vehicle includes a driveshaft, first axle, second axle, first clutch, second clutch, and controller. The driveshaft is selectively coupled to outputs of the first and second axles by the first and second clutches, respectively. The controller is programmed to, in response to a command to reconnect the driveshaft to the outputs of the first and second axles, close the second clutch to transfer loads from the second axle to the driveshaft, adjust the slip speed of the first clutch to within a target range, and close the first clutch.
