Abstract
Methods and systems for improving traction and control of a tandem axle are described. In one example, a controller automatically locks an inter-axle differential so that traction of a vehicle may be improved. The approach may also include automatically locking one or more axle differentials in conjunction with locking of the inter-axle differential.
