Abstract: A hydraulic excavator includes a base body portion, a movable portion, a hydraulic cylinder, a position sensor, a rotary encoder, and a control unit. The rotary encoder includes a light emitting unit, a light receiving unit, and a disk unit having a plurality of transmission portions. The control unit measures the stroke length of the hydraulic cylinder by correcting deviation of the stroke length, which is measured by the position sensor, based on the pulse signal output from the rotary encoder. In this way, there can be obtained a hydraulic excavator capable of precisely measuring a stroke length of a hydraulic cylinder driving a work implement, as well as a method for measuring the stroke of the hydraulic cylinder of the hydraulic excavator.

Abstract: A control line determinator determines whether or not a work state of a work implement is a predetermined work state. A display controller generates a display signal including a target surface of a construction object or a control line indicating a surface which is different from the target surface and which a bucket is to be prevented from entering. The display controller makes a display form of the control line or the target surface in the display signal different according to whether or not the work state is the predetermined work state.

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.
