  • YAW ESTIMATION SYSTEMS AND METHODS FOR RIGID BODIES OF EARTHMOVING MACHINES CONNECTED BY A REVOLUTE JOINT
    Publication number: 20240044109
    Abstract: Yaw estimation systems and methods for an earthmoving machine and control architecture to receive roll and pitch input from an engine end frame (EEF) inertial motion unite (IMU) and from a non-engine end frame (NEEF) IMU, estimate a yaw articulation angle of the NEEF relative to the EEF by at least two different estimation methods based on the received roll and pitch input, fuse the at least two different estimation methods to generate an updated yaw articulation angle, calculate a yaw articulation rate based on the received roll and pitch input, integrate as an integration the updated yaw articulation angle and the yaw articulation rate, generate a real-time yaw articulation angle estimate of the NEEF relative to the EEF based on the integration, and operate the earthmoving machine based on the real-time yaw articulation angle estimate.

  • System and method for determining a ground speed of a machine
    Patent number: 9199616
    Abstract: The disclosure describes, in one aspect, a method for determining a machine ground speed. The method includes determining a first speed from a position determining system, determining a direction the machine is traveling at the first speed, determining a machine rate of inclination, and determining a compensated ground speed as a function of the first speed and the machine rate of inclination.
