1. A method for determining a cross slope created by a work implement on a work machine, the work machine comprised of movably connected front and rear frames, said work implement movably connected to at least one of said frames, comprising the steps of:

  • sensing a plurality of machine parameters, said machine parameters including at least a roll of said work machine, a pitch of said work machine, and an articulation angle;

    sensing at least one work implement parameter, said work parameter including at least an angle of rotation of said work implement relative to said work machine;

    determining a position of said work implement in response to said work machine parameters and said at least one work implement parameter;

    determining a direction of travel of at least one of said frames of said work machine; and

    determining a cross slope in response to said at least one direction of travel and said work implement position.
