Claim 7:
8. A method for adjusting articulation angle in an auto steering operation of a work vehicle, comprising:
receiving a signal indicative of a percentage of travel of an articulation joystick;
calculating an articulation desired angle change partially based on the percentage of travel of the articulation joystick;
adding the articulation desired angle change to an articulation last desired angle which was a previous articulation desired angle to obtain an articulation desired angle;
calculating a difference between an articulation angle detected by an articulation angle sensor and the articulation desired angle to obtain an auto steering articulation error;
adjusting the articulation angle by an articulation actuator based on the auto steering articulation error; and
providing a lookup table, a value of which corresponding to the percentage of travel of the articulation joystick;
wherein calculating the articulation desired angle change comprises multiplying the value of the lookup table, task rate, and a pre-set full angular velocity.
