First Claim
Patent Images
1. A method for controlling a component of a machine based on a compensated ground speed, the method comprising:
- determining a first speed from a position determining system;
determining, by a microprocessor, a direction the machine is traveling at the first speed;
determining, by an inclination sensor, a machine rate of inclination;
determining, by a microprocessor, a compensated ground speed as a function of the first speed, the machine rate of inclination, and a compensation term;
wherein the compensation term is determined as a function of a distance between a component of the position determining system and a location of a pitch center of the machine; and
controlling the machine component based on the compensated ground speed.
