Abstract: A control may obtain first data related to a plurality of positions of an implement of a work machine during a first time period and may determine, based on the first data, a first noise value related to at least one velocity of the implement for the first time period. The control device may obtain second data related to a plurality of positions of the implement during a second time period and may determine, based on the second data, a second noise value related to at least one velocity of the implement for the second time period. The control device may determine, based on the first noise value and the second noise value, a start of motion of the implement. The control device may cause, based on determining the start of motion of the implement, the implement to be calibrated.

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.

Abstract: An controller uses one of several transfer curves to map steering angle of an articulated machine to articulation angle. Because an articulated machine may have a range of steering angles that is much greater than the range of articulation angles, the controller uses one of several techniques to map the full range of steering angles to the full range of articulation angles. One technique involves multiple non-zero slope regions, another technique uses a less than one-to-one linear transfer function of steering angle to articulation angle.

Abstract: A controller monitors groundspeed in an articulated machine 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 on switch was activated compared to a machine power cycle or an operator not being present, the automatic articulation control function may be inactivated until the on switch is toggled. If the articulated machine 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 may simply be stalled to due working conditions and the automatic articulation control function may be maintained.
