摘要： A control system for a work vehicle includes at least one sensor, an operating device, and a controller. The operating device includes at least one operating member. The controller is programmed to control a work implement of the work vehicle based on signals from the at least one sensor and the operating device. The controller is further programmed to use the signals to obtain a distance between the work implement and a design terrain which represents a target shape of a work object, and to determine whether a surface compaction determination condition indicating that work performed by the work implement is surface compaction work is satisfied. The controller executes a surface compaction control in which a velocity of the work implement toward the design terrain is limited in response to the distance between the work implement and the design terrain when the surface compaction determination condition is satisfied.

摘要： A display system includes a display and a controller. The controller acquires machine position data indicative of a position of a work machine. The controller acquires a separation distance in a width direction of the revolving body between a work point of the work implement and a revolving axis. The work point is spaced from the revolving axis in the width direction. The controller acquires target position data indicative of a target position of the work implement. The controller causes the display to display a guideline indicative of the target position and a guide image indicative of the position of the work machine based on the machine position data and the target position data. The guide image includes a first image and a second image. The first image indicates a position of the revolving axis. The second image indicates a position away from the revolving axis by the separation distance.

摘要： A stop control unit carries out control, when a moving speed of a bucket in a direction toward target design topography is the same in both of a first specifying state in which a bucket weight specifying portion specifies a weight of the bucket as large and a second specifying state in which the bucket weight specifying portion specifies a weight of the bucket as small, such that the moving speed of the bucket in the direction toward the target design topography is reduced from a position more distant from the target design topography in the first specifying state than in the second specifying state.

摘要： A work vehicle includes: a hydraulic operation apparatus for operating an actuator; a main controller configured to generate a command current in accordance with an amount of operation of the operation apparatus; an electromagnetic proportional control valve configured to generate command pilot pressure in accordance with the command current; and a main valve configured to adjust a flow rate of hydraulic oil for operating the actuator based on the command pilot pressure. The electromagnetic proportional control valve is provided in a pilot oil passage that connects a pilot pump and a main valve, and configured to utilize hydraulic pressure supplied from the pilot pump to generate command pilot pressure. The operation apparatus is provided in an operation apparatus oil passage that is different from the pilot oil passage.

摘要： A control deciding unit for deciding to execute a leveling control for controlling a work implement so that the work implement moves along a design terrain when a leveling determination condition is satisfied. The control deciding unit decides to execute a surface compaction control for limiting the velocity of the work implement toward the design terrain in response to the distance between the work implement and the design terrain when a surface compaction determination condition is satisfied. The control deciding unit maintains the surface compaction control when the leveling determination condition is satisfied while the surface compaction control is being executed.

摘要： An earthmoving machine includes a work implement, a distance calculation unit, and a hydraulic cylinder control unit. The work implement includes a boom, an arm, and a bucket. The distance calculation unit calculates a distance between a monitoring point in the bucket and design topography representing an aimed shape of a land grading target. The hydraulic cylinder control unit outputs a command signal for lowering the boom when the distance between the monitoring point and the design topography is equal to or smaller than a prescribed value and when the bucket is expected to move in such a direction that the monitoring point moves away from the design topography as a result of an operation of the arm.

摘要： A measurement value acquisition unit acquires measurement values from a plurality of sensors. A posture calculation unit calculates a posture of an attachment with respect to a vehicle body. An intervention control unit determines a virtual rotation axis based on the calculated posture of the attachment. An intervention control unit generates a control signal for the tilt rotator to rotate the attachment around the virtual rotation axis so that a design surface and teeth of the attachment are approximately parallel to each other, based on the calculated posture of the attachment. An output unit outputs the generated control signal.
