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.

Abstract: An controller (102) uses one of several transfer curves (400, 408, 420, 430) to map steering angle of an articulated machine (10) to articulation angle. Because an articulated machine (10) may have a range of steering angles that is much greater than the range of articulation angles, the controller (102) 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 translation: 控制器（102）使用多个传递曲线（400,408,420,430）中的一个将铰接机器（10）的转向角映射到关节角度。 由于铰接机器（10）可以具有比接合角度范围大得多的转向角范围，所以控制器（102）使用几种技术之一来将整个范围的转向角映射到关节角度的全范围 。 一种技术涉及多个非零斜率区域，另一种技术使用转向角与关节角度的小于一对一的线性传递函数。

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: 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: 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: According to a method, data related to at least one position of an implement (116) of a work machine (100) that has moved to a set position is obtained. One or more first noise amplitudes associated with the data are identified and, based on the one or more first noise amplitudes, a noise band related to the implement vibrating at the set position is determined. One or more second noise amplitudes associated with the data are identified and, based on the noise band and the one or more second noise amplitudes, it is determined that the implement has settled at the set position. Based on determining that the implement has settled at the set position, the implement is allowed to move to another position.

Abstract: A motor grader is disclosed. The motor grader may include an articulated implement. The motor grader may include an articulation control device. The articulation control device may be configured to determine that articulation motion of the articulated implement is occurring, for a threshold amount of time, in a second direction that is different from a first direction indicated by an articulation control command. The articulation control device may be configured to perform a response action based on determining that articulation motion of the articulated implement is occurring, for the threshold amount of time, in the second direction that is different from the first direction indicated by the articulation control command.
