The present disclosure provides methods for adjusting steering angle and articulation angle in an auto articulation operation of a work vehicle. The percentage of travel of a steering joystick of the work vehicle at least partially determines a steering desired angle change, which can be used to calculate a steering desired angle and an articulation desired angle change. The difference between the steering desired angle and a steering angle detected by a steering angle sensor is used to adjust the steering angle. The articulation desired angle change can be used to calculate an articulation desired angle. The difference between the articulation desired angle and an articulation angle detected by an articulation angle sensor is used to adjust the articulation angle.

Systems and methods for coordinating and providing steering assistance between towing vehicles and towed vehicles during towing events. The towing steering assistance may be provided by the towed vehicle in the form of assistive steering maneuvers to assist the towing vehicle with turning during the towing event. The assistive steering maneuvers may be provided to account for turning maneuvers, steering compensation, and stability events of the coupled vehicles during the towing events, for example.

A vehicle includes a frame, and at least one front and rear wheel. The total number of front and rear wheels is at least three. The vehicle includes a mechanism for driving at least one of the front and rear wheels, a seat for a driver, and at least one fall prevention element to prevent, in a closed position of the fall prevention element, a driver from falling off the seat. In an open position of the fall prevention element, a driver can freely take a seat from the outer side of the vehicle via the space which, in the closed position, is occupied by the fall prevention element, or can step out of the vehicle; the fall prevention element slides between the open and closed positions.

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.

Steering and roll control systems to counteract yaw and/or roll forces during operation of a vehicle having first and second wheeled members coupled together by an articulating joint mechanism that is configured to pivot in a yaw direction and/or a roll direction. The steering assistance systems include a biasing unit configured to apply a counteracting force to bias the first and second wheeled members toward a straight-line arrangement thereof. The roll control systems include an additional biasing unit configured to apply a counteracting force to bias the first and second wheeled members toward a level alignment arrangement of the vehicle.
