Vehicle auto turning control system

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

A system and method for steering a machine. The system may comprise a controller configured to receive a steering command and determine a target angular turn rate for the body and a target turn direction for the body. The controller may be further configured to determine a steering mode based on a transmission output torque, the steering mode including Traction-steering, Assisted-steering or Implement-steering. When the steering mode is Assisted-steering, the controller is configured to steer the machine in the target turn direction and at the target angular turn rate by (a) moving an implement from a first position to a second position and (b) diverting or removing power from a first ground engaging traction member. When the steering mode is Implement-steering, the controller is configured to move the implement from a first position to a second position to steer the machine in the target turn direction and at the target angular turn rate without diverting or removing power from the first ground engaging traction member.
