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.
