Method and apparatus for determining a cross slope of a surface

A method for determining a cross slope created by a work implement on an earthmoving machine, the work implement being movably connected to a frame of the earth moving machine comprising the steps of:

• sensing a plurality of machine parameters, said machine parameters including a roll of said machine;
• sensing a plurality of work implement parameters, said work implement parameters including an angle of rotation of the work implement relative to the machine;
• and
• determining said cross slope in response to said machine parameters, said work implement parameters, and said angle of rotation of said work implement.

An apparatus configured to determine a cross slope created by an earthmoving machine having a work implement, the work implement being movably connected to a frame of the earth moving machine, comprising:

• a machine sensor system configured to sense a plurality of machine parameters and responsively generate a plurality of machine parameter signals;
• a work implement sensor system configured to determine a plurality of work implement parameters and responsively generate a plurality of work implement parameter signals;
• and
• a controller configured to receive said machine parameter signals, and said work implement parameter signals, determine a direction of travel of the machine in response to said machine and said work implement parameters, determine a position of said work implement in response to said machine and said work implement parameters, and determine the cross slope in response to said machine direction of travel and said work implement position.
