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: 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 translation: 控制器使用几个传递曲线之一来映射铰接机器的转向角度与铰接角度。 由于铰接机器可以具有远大于关节角度范围的转向角范围，所以控制器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。
