摘要：
A rear wheel drive assist for an articulated machine such as a wheel tractor scraper, the machine including a first frame section having a first longitudinal axis, a second frame section with a second longitudinal axis, the first and second frame sections being pivotally connected to an articulation hitch, and an articulation sensor configured to provide an articulation angle signal indicative of an articulation angle formed between the first and second longitudinal axes. The rear wheel drive assist includes a drive motor operatively connected to the rear wheel of the machine, and a controller configured to control operation of the rear wheel drive assist based upon the articulation angle signal.
