Patent ID: 8459394

Claim:
An articulated machine, comprising: a first frame section having a power source drivingly connected to at least one front wheel, the first frame section further having a first longitudinal axis; a first wheel sensor configured to provide an indication of a front wheel speed; a second frame section having at least one rear wheel and a second longitudinal axis, the first and second frame sections pivotally connected at an articulation hitch; an articulation sensor configured to provide an articulation signal indicative of an articulation angle between first and second longitudinal axes; and a rear wheel drive assist providing a power output to the at least one rear wheel, comprising: at least one drive motor operatively connected to the at least one rear wheel; and a controller communicatively coupled to the first wheel sensor and the articulation sensor and configured to: determine a desired rear wheel speed based on the articulation signal, the desired rear wheel speed being less than the front wheel speed; and modulate the power output to the at least one rear wheel based upon the desired rear wheel speed.
