Articlulated vehicle stabilization system

A vehicle including:

• a first frame;
• a first wheel assembly operably coupled to the first frame;
• a second frame defining a longitudinal axis;
• a second wheel assembly operably coupled to the second frame, the second wheel assembly including a tandem pivotally coupled to the second frame at a pivot coupling, a front wheel rotatably supported by the tandem, and a rear wheel rotatably supported by the tandem;
• a bin supported by the second frame and configured to support a load;
• a frame coupling between the first frame and the second frame, the coupling configured to provide pivoting movement between the first frame and the second frame about a vertical axis;
• a vehicle condition sensor configured to detect a condition of the vehicle;
• a controller in communication with the vehicle condition sensor;
• and
• a stabilizer operably coupled to the second frame and the tandem, the stabilizer configured to restrict pivoting movement of the tandem in response to the condition sensed by the vehicle condition sensor.

A method of stabilizing a vehicle, the method comprising the steps of:

• providing a vehicle having a first frame and a second frame that are pivotally connected to one another by a pivot frame coupling to steer the vehicle, the first frame having a first wheel assembly and the second frame having a second wheel assembly, the second wheel assembly including a tandem pivotally coupled to the second frame at a tandem coupling, a front wheel rotatably supported by the tandem and a rear wheel rotatably supported by the tandem, and a stabilizer operably coupled to the tandem;
• pivoting the first frame relative to the second frame by an articulation angle about the pivot coupling;
• sensing a vehicle condition;
• and
• controlling the stabilizer in response to the sensed vehicle condition.
