Abstract
When engaged, an articulation controller automatically adjusts an angle of articulation between a front frame and a rear frame of a motor grader based on a steering angle of the front wheels. If a groundspeed of the motor grader exceeds a threshold groundspeed, the articulation controller enters a mode that only allows decreasing the angle of articulation of the motor grader. When the angle of articulation reaches zero, the articulation controller disengages until the groundspeed is reduced below the threshold groundspeed.
