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 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.

Abstract: A construction machine control system controls a construction machine including a traveling device, a work machine having a working tool, and a swing structure to which the work machine is attached and which is attached to the traveling device to swing with respect to the traveling device. The construction machine control system includes a position detection device that detects a first position which is a position of a partial portion of the construction machine and outputs the first position as first position information; a state detection device that detects and outputs operation information indicating an operation of the construction machine; and a processing device that calculates a second position corresponding to the position of the partial portion using the first position information and the operation information and calculates a position of at least a partial portion of the work machine using second position information.

Abstract: A work vehicle includes a boom, an arm, a bucket, an arm cylinder, a direction control valve, a calculation portion, and a speed determination portion. The calculation portion calculates an estimated speed of the arm cylinder based on correlation between an amount of movement of the spool of the direction control valve in accordance with an amount of operation of an arm control lever and a speed of the arm cylinder. The speed determination portion determines a target speed of the boom based on the estimated speed of the arm cylinder. When the amount of operation of the arm control lever is smaller than a prescribed amount, the calculation portion calculates a speed higher than a speed of the arm cylinder in accordance with correlation as the estimated speed of the arm cylinder.
