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 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 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 type information input unit receives an input of type information for identifying an attachment. A storage unit stores in advance correspondence between the type information and a weight or weight classification of the attachment. A specification unit specifies a corresponding weight or weight classification based on the type information input to the type information input unit.
