A control system for a work vehicle includes a controller. The controller acquires actual topography data indicating an actual topography to be worked. The controller determines a target design topography indicating a target trajectory of a work implement of the work vehicle based on the actual topography. The controller acquires an uneven surface parameter indicating the degree of surface unevenness of the actual topography. The controller changes the target design topography according to the uneven surface parameter.

An enhanced visibility system for a work machine includes an image capture device, a sensor, one or more control circuits, and a display. The image capture device is configured to obtain image data of an area surrounding the work machine. The sensor is configured to obtain data regarding physical properties of the area surrounding the work machine. The control circuits are configured to receive the image data and the data regarding the physical properties, and augment the image data with the data regarding the physical properties to generate augmented image data. The display is configured to display the augmented image data to provide an enhanced view of the area surrounding the work machine.

A work vehicle includes a work implement operatively connected to a frame through an actuator having a cylinder and a piston rod. Control circuitry is operatively connected to the actuator and includes a processer and a memory, wherein the memory is configured to store program instructions and the processor is configured to execute the stored program instructions to: identify one of an initial retracted reference position of the piston rod based on an initial minimum retracted distance or an initial extended reference position of the piston rod based on an initial maximum extended distance; identifying an end of stroke position of the piston rod after identifying one of the initial retracted reference position of the piston rod or the initial extended reference position of the piston rod; and moving the work implement with respect to the work vehicle based on a work implement command modified by the identified end of stroke position.

A system and method for steering a machine. The system may comprise a controller configured to receive a steering command and determine a target angular turn rate for the body and a target turn direction for the body. The controller may be further configured to determine a steering mode based on a transmission output torque, the steering mode including Traction-steering, Assisted-steering or Implement-steering. When the steering mode is Assisted-steering, the controller is configured to steer the machine in the target turn direction and at the target angular turn rate by (a) moving an implement from a first position to a second position and (b) diverting or removing power from a first ground engaging traction member. When the steering mode is Implement-steering, the controller is configured to move the implement from a first position to a second position to steer the machine in the target turn direction and at the target angular turn rate without diverting or removing power from the first ground engaging traction member.

Embodiments of a work vehicle magnetorheological fluid (MRF) joystick system include a joystick device having a base housing, a joystick movably mounted to the base housing, and a joystick position sensor configured to monitor joystick movement. An MRF joystick resistance mechanism is controllable to vary a joystick stiffness resisting movement of the joystick relative to the base housing, while a controller architecture is coupled to the joystick position sensor and to the MRF joystick resistance mechanism. The controller architecture is configured to: (i) selectively place the work vehicle MRF joystick system in a modified joystick stiffness mode during operation of the work vehicle; and (ii) when the work vehicle MRF joystick system is placed in the modified joystick stiffness mode, command the MRF joystick resistance mechanism to vary the joystick stiffness based, at least in part, on the movement of the joystick relative to the base housing.

Systems and methods are disclosed herein for controlling a work implement (e.g., front-mounted blade) relative to a work vehicle to produce a desired profile in a ground surface. Chassis-mounted sensor(s) detect an actual pitch velocity and an actual pitch angle of the chassis relative to the ground. Further sensor(s) detect an actual lift position of the blade relative to the chassis. A desired profile to be produced by the blade with respect to the ground surface is determined, for example via an automated grade control system, via manually-initiated trigger(s), and/or via time-based rolling averages of detected values. A position of the implement is automatically controlled as a function of each of the actual pitch velocity, the actual pitch angle of the chassis relative to the ground, and the actual lift position of the work implement relative to the chassis, corresponding to the desired profile with respect to the ground surface.

A motor includes a rotor including a rotating shaft extending along a center axis, a cylindrical rotor core provided outside the rotating shaft in a radial direction, and two discoid weight plates provided at two ends of the cylindrical rotor core in an axial direction, and a stator opposing the rotor in the radial direction. A radius of each weight plate is smaller than a radius of the rotor core, and a difference between the radius of the rotor core and the radius of each weight plate is larger than an air gap between an outside of the rotor core in the radial direction and an inside of the stator in the radial direction.

In accordance with one embodiment of the present disclosure, a material moving machine comprises a pilot hydraulic switching system. The pilot hydraulic switching system comprises a control unit, a first directional valve, and a second directional valve. The control unit is configured to operate the first and second directional valves to shift a variable position actuator valve between a static state, a retract state, and an extend state. The actuator valve comprises a first and second control element. In the retract and extend states, the first and second directional valves control fluid flow to the variable position actuator valve with a positive net pressure on either the first or second control elements and a negative net pressure on the other control element to move the material moving implement. In the static state, the first and second directional valves control fluid flow equally on the first and second control elements.

A display system includes a display device, an imaging device that is provided at a work machine, a three-dimensional measurement device that is provided at the work machine, and a display control device that, based on three-dimensional terrain data in a movement direction of the work machine measured by the three-dimensional measurement device, causes a symbol image indicating a terrain height in the movement direction to be superimposed on a terrain image in the movement direction captured by the imaging device, causing the display device to display the obtained image thereon.

A track-type tractor may comprise an operator cab, an engine, a frame supporting the operator cab and the engine, and an implement configured to move a load. The track-type tractor may further comprise at least one hydraulic lift cylinder configured to raise and lower the implement. The hydraulic lift cylinder may include a head end, a rod end, and a cylinder barrel. The cylinder barrel may be connected to the backside of the implement, and the rod end may be connected to the frame.
