  • Publication number: 20240117599
    Abstract: The present disclosure provides methods for adjusting steering angle and articulation angle in an auto steering operation of a work vehicle. The percentage of travel of an articulation joystick of the work vehicle at least partially determines an articulation desired angle change, which can be used to calculate an articulation desired angle and a steering desired angle change. The difference between the articulation desired angle and an articulation angle detected by an articulation angle sensor is used to adjust the articulation angle. The steering desired angle change can be used to calculate a steering desired angle. The difference between the steering desired angle and a steering angle detected by a steering angle sensor is used to adjust the steering angle.
