Operating a vehicle in an automated steering control mode wherein the vehicle includes a controller operatively coupled with an articulated steering system and a front axle steering system. The controller is configured to identify a desired path of curvature of the vehicle and determine a front axle steering angle of the front axle steering system and command the front axle steering system to operate at the front axle steering angle and also determine an articulation steering angle of the articulated steering system and command the articulated steering system to operate at the articulation steering angle. A further form includes operating front and rear ground engaging means at a designated speed, and thereafter operating the articulated steering system and the front axle steering system based on the designated speed being greater than a transport speed threshold, less than a field speed threshold or between the two.

Vehicles, control systems for vehicles, and methods of operating vehicles are disclosed herein. A vehicle includes a frame structure, a front section, a rear articulation section, and a control system. The front section is coupled to the frame structure and to a front plurality of wheels supported for movement on a front axle. The rear articulation section is coupled to the frame structure and to a rear plurality of wheels supported for movement on a rear axle. The rear articulation section is pivotally coupled to the front section via an articulation joint and arranged opposite the front section along a vehicle axis. The control system is coupled to the frame structure and includes a mode selector configured to provide input indicative of a mode selected by an operator in use of the vehicle and a controller communicatively coupled to the mode selector.

Provided is a vehicle capable of: acquiring an image of a road in front of a vehicle in an autonomous driving mode; recognizing a lane line, a subject lane, and an obstacle on the acquired image of the road; determining whether the recognized obstacle is in a stationary state based on obstacle information detected by an obstacle detector; acquiring, if the obstacle in the stationary state exists on at least one of two subject lane lines constituting the subject lane, a width of involvement of the lane line crossed by the obstacle; determining whether keeping of travelling on the subject lane is to be performed based on the acquired width of involvement; performing a deflection control within the subject lane to avoid the obstacle in the stationary state if it is determined that the keeping of travelling on the subject lane is to be performed; and performing control of departure from the subject lane or deceleration control if it is determined that the keeping of travelling on the subject lane is not to be performed.

A hydraulic circuit for a pair of cylinders of an articulation system includes a pump, a reservoir, a directional control valve (DCV), a pair of actuator valves (AVs) and an articulation charge circuit (ACC). The DCV is fluidly coupled to the pump, the reservoir and the pair of cylinders via a supply line, a fluid return line and a pair of cylinder supply lines (CSLs) respectively. Each CSL has a load check valve (LCV) therein. The AVs are fluidly coupled with the DCV and the pump via a pilot supply line (PSL) for actuating movement of the DCV. The ACC, associated with the PSL and each cylinder supply line downstream of the associated LCV, charges a corresponding CSL with fluid from the PSL for increasing a pressure in the corresponding CSL when the pressure in the corresponding CSL falls below the pressure of fluid associated with the PSL.

A controller controls a first drive source and a second drive source based on a rotation speed of a right rear wheel measured by a rotation speed sensor and a rotation speed of a left rear wheel measured by a rotation speed sensor, to thereby independently control a rotation speed of each of a right front wheel and a left front wheel.

Vehicles, systems and methods for providing articulating two section vehicles with tracks, and a front body attached superstructure with telescopic forklift, for use on all terrain condition applications. The vehicle can include front and rear track assemblies that can tilt up and down while traveling over different ground surfaces. Each of the track assemblies can have rotatable articulating/oscillating track wheels which can traverse different contoured surfaces. The right and left tracks on both the front and rear track assemblies can separately extend outward and inward from underneath the vehicles to add stability to the vehicles. The cab can be raised and lowered to add greater visibility for the operator. Hydraulics can be used for raising and lowering the extendable boom and operator cab, as well as controlling the body articulating hinge, the articulating tracks and the tilting controls for the front track assembly.
