System and method for determing a position on an implement relative to a reference position on a machine

An implement control system disposed in a machine for determining a position on the machine relative to a reference position on the machine having an implement operatively connected to a rigid body of the machine, comprising:

• a controller operatively connected to the implement, the controller adapted to:
• determine the reference position in a coordinate system;
• determine a first desired position on the implement in the coordinate system;
• determine a first relative desired position wherein the first desired position is relative to the reference position;
• and
• update the implement control system using the first relative desired position.

A method for determining a position on a machine relative to a reference position on the machine, the method comprising:

• determining the reference position on a rigid body of the machine when the machine is at a first machine location;
• determining a first desired position when the machine is at a second machine location, wherein the first desired position is representative of a first edge of an implement operatively connected to the rigid body of the machine;
• determining a second desired position when the machine is at the second machine location, wherein the second desired position is representative of a second edge of the implement;
• receiving a signal from sensor operatively connected to the machine, wherein the signal is indicative of at least one of pitch, roll, or hydraulic cylinder data;
• determining a first relative desired position wherein the first desired position is relative to the reference position;
• determining a second relative desired position wherein the second desired position is relative to the reference position;
• determining a measurement indicative of a vertical dimension of the machine, a measurement indicative of a first horizontal dimension of the machine, and a measurement indicative of a second horizontal dimension of the machine, wherein each of the vertical, the first horizontal, and the second horizontal dimension measurements is based in part on at least one of the reference position, the first relative desired position, the second relative desired position, the pitch signal, the roll signal, or the hydraulic cylinder data signal;
• and
• updating an implement control system using the first and second relative desired positions, and the vertical, the first horizontal, and the second horizontal dimension measurements.
