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.

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 is delayed until error conditions are cleared or a steering angle to alignment angle mismatch is corrected. A controller monitors a selector setting indicating a desire to activate the automatic articulation control function. The controller 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 may be set to inform an operator that the automatic articulation control function is pending activation.
Abstract translation: 在关节机器中激活自动关节运动控制功能被延迟，直到错误状况被清除或者对准角度失配的转向角被校正。 控制器监视选择器设置，指示激活自动关节控制功能的愿望。 控制器还评估是否存在诸如地面速度低，所需传感器信号丢失或关节错位的条件。 如果是这样，则监视条件，并且在校正时，激活自动关节运动控制功能。 可以设置指示器以通知操作者自动关节运动控制功能正在等待激活。

Abstract: An articulation control system for a machine may include an actual steering sensor configured to provide a signal indicative of an actual steering angle, a timer configured to provide a signal indicative of an elapsed predetermined period of time, and a controller in communication with the actual steering sensor and the timer. The controller may be configured to regulate automatic articulation to zero based on signals received from the actual steering sensor and the timer.
