    Abstract: When engaged, an articulation controller (102) automatically adjusts an angle of articulation between a front frame (12) and a rear frame (14) of a motor grader (10) based on a steering angle of the front wheels (58; 60). If a groundspeed of the motor grader (10) exceeds a threshold groundspeed, the articulation controller (102) enters a mode that only allows decreasing the angle of articulation of the motor grader (10). When the angle of articulation reaches zero, the articulation controller disengages until the groundspeed is reduced below the threshold groundspeed.

    Abstract: A controller (102) monitors groundspeed in an articulated machine (10) and selectively disables an automatic articulation control function when the groundspeed is at or near zero. If there is an indication that an operator may not be aware that the automatic articulation control function is active by comparing when a mode selector (110) was activated compared to a machine power cycle or an operator not being present, the automatic articulation control function may be inactivated until the mode selector (110) is toggled. If the articulated machine (10) is in neutral and the groundspeed is at or near zero, the automatic articulation control function may disabled. If the groundspeed is at or near zero but the transmission is not in neutral, the machine (10) may simply be stalled to due working conditions and the automatic articulation control function may be maintained.

    Abstract: Activation of an automatic articulation control function in an articulated machine (10) is delayed until error conditions are cleared or a steering angle to alignment angle mismatch is corrected. A controller (102) monitors a selector (110) setting indicating a desire to activate the automatic articulation control function. The controller (102) also evaluates whether conditions such as low ground speed, loss of signal from needed sensors, or articulation misalignment are present. If so, the conditions are monitored and when corrected, the automatic articulation control function is activated. An indicator (204, 206) may be set to inform an operator that the automatic articulation control function is pending activation.

    Abstract: A controller may identify a command to move an implement in a particular direction and an amount of time for the implement to move in the particular direction. The controller may determine an estimated velocity of the implement moving in the particular direction. The controller may determine a predicted travel distance of the implement in the particular direction. The controller may cause, based on a stop position associated with the particular direction and the predicted travel distance of the implement in the particular direction, the implement to move from a current position to a reset position. The controller may cause the command to be executed to cause the implement to move, in the particular direction and for the amount of time, from the reset position to another position without hitting the stop position associated with the particular direction.
