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.
Claims8
A work vehicle, comprising:
- a work implement including a boom, an arm, and a bucket;
- a weight specifying portion which specifies a weight of said bucket attached to said arm;
- a distance obtaining portion which obtains a distance between a cutting edge of said bucket and target design topography;
- and
- a stop control unit which carries out stop control for stopping an operation of said work implement before said cutting edge of said bucket reaches said target design topography when said cutting edge of said bucket comes closer to said target design topography, and carries out control, when a moving speed of said bucket in a direction toward said target design topography is equal in both of a first specifying state in which said weight specifying portion specifies a weight of said bucket as a first weight and a second specifying state in which said weight specifying portion specifies a weight of said bucket as a second weight smaller than said first weight, such that the moving speed of said bucket in the direction toward said target design topography is reduced from a position more distant from said target design topography in said first specifying state than in said second specifying state.
