Abstract:
A pilot neutralizing system of a work vehicle may include a pilot neutralizer. The work vehicle may include a first frame portion and a second frame portion. The work vehicle has an actuating assembly used to pivot the first frame portion relative to the second frame portion. The pilot neutralizer is electrically coupled to a controller receiving a signal indicative of an articulation position. The pilot neutralizer is hydraulically coupled between an operator control member and a steering valve to selectively change a pilot signal at the steering valve. The pilot signal is used to switch the steering valve to change a direction of a hydraulic fluid flowing from the steering valve to the actuating assembly. When the articulation position reaches a cushion region during steering, the pilot neutralizer is de-energized or energized by the controller to change the pilot signal at the steering valve to resist the actuating assembly from moving.
