Abstract: There is provided a work vehicle in which a work implement can be freely operated. The work vehicle includes: a design surface information acquiring unit for acquiring data of a design surface indicative of a target shape of a work object by the work implement; a cutting edge position computing unit for computing a position of a cutting edge of a bucket; and an operation restricting unit for executing operation restriction control by which, when the cutting edge of the bucket comes closer to the design surface, operation of the work implement is stopped before the cutting edge of the bucket reaches the design surface. In a case where the cutting edge is located away from the design surface in a downward perpendicular direction by a prescribed distance or longer, the operation restricting unit does not execute the operation restriction control.

Abstract: A main controller controlling an operation of a work vehicle includes a determination unit and an abnormal condition determination unit. The determination unit determines whether or not an attachment has a sensor based on information on an attachment. When the determination unit determines that the attachment has the sensor and when the abnormal condition determination unit cannot receive a signal from the sensor, the abnormal condition determination unit determines that an abnormal condition has occurred.

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 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.
