Abstract: 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.

Abstract: An excavation control system includes a working unit having a bucket, a designed landform data storage part storing designed landform data, a bucket position data generation part that generates bucket position data, a designed surface data generation part, and an excavation limit control part. The designed surface data generation part generates superior and subordinate designed surface data based on the designed landform and bucket position data. The superior designed surface data indicates a superior designed surface corresponding to a position of the bucket. The subordinate designed surface data indicates a first subordinate designed surface linked to the superior designed surface. The designed surface data generation part generates shape data indicating shapes of the superior designed surface and the first subordinate designed surface. The excavation limit control part automatically adjusts a position of the bucket.

Abstract: When correcting an error caused by deviation of an attitude detection device with respect to a work machine including a swing body which swings, a working implement being attached to the swing body, the attitude detection device outputting an attitude of the work machine, the error is corrected by using a first position which is a position of a part of the work machine when the work machine is in a first attitude and a second position which is a position of the part when the work machine is in a second attitude.

Abstract: A distance obtaining unit obtains the distance between a work implement and a design terrain. A work aspect determining unit determines a work aspect by the work implement. A limit velocity deciding unit limits the velocity of the work implement when the distance between the work implement and the design terrain becomes smaller. When the work aspect is surface compaction work and the distance between the work implement and the design terrain is within a first range of at least a portion that is equal to or less than a predetermined first distance, the limit velocity deciding unit increases the limit velocity of the work implement in comparison to when the work aspect is an aspect of a work other than surface compaction, or cancels the limiting of the velocity of the work implement.

Abstract: 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.

Abstract: A work vehicle includes a vehicular body, a work implement, an angle sensor, and a work implement control unit. A bucket is rotatable with respect to an arm around a bucket axis in parallel to an arm axis and a tilt axis orthogonal to a bucket axis. The angle sensor is provided in the bucket and detects an angle of inclination of the bucket with respect to a horizontal plane. The work implement control unit starts control of the work implement in which an operation of the work implement is controlled at least partially automatically when an angle of inclination of the bucket detected by the angle sensor is smaller than a first threshold value, and does not start control of the work implement when an angle of inclination of the bucket detected by the angle sensor is equal to or greater than the first threshold value.

Abstract: A construction machine has a work implement and a work implement operating device. The work implement has a boom, arm, and bucket. A limit velocity determining unit determines a limit velocity of the boom from the limit velocity of the entire work implement, the arm target velocity, and the bucket target velocity. The distance when the blade tip of the bucket is positioned outside of the design plane is a positive value and the velocity in a direction from inside of the design plane toward outside of the design plane is a positive value. The first limit condition includes a condition that the limit velocity of the boom is greater than the boom target velocity. When the first limit condition is satisfied, a work implement control unit controls the boom to match the limit velocity of the boom and controls the arm to match the arm target velocity.
