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.
