A vehicle includes a first axle system operatively connected to a first set of wheels, a second axle system operatively connected to a second set of wheels, a first drive system operatively connected to the first set of wheels, a second drive system operatively connected to the second set of wheels independent of the first set of wheels, and a traction management control module electrically coupled to at least one of the first and second drive systems. The traction management control module calculates a torque capability of the corresponding one of the first and second axle systems and selectively transmits an axle torque command to the corresponding one of the first and second axle systems based on the torque capability.
