ABSTRACT:
A hitch assembly control system for an off-highway vehicle such as an agricultural tractor is operable in both position and draft control modes. The control system is capable of transitioning from the position mode to the draft mode, and from the draft mode to the position mode, under particular conditions. For the transition from position to draft mode, these conditions include a target hitch position being greater than both a hitch position command and a hitch position feedback. For the transition from draft to position mode, these conditions include the hitch position command being greater than the hitch position plus a hysteresis factor, or less than the hitch position command that existed back at the transition into the draft mode.
