A work vehicle 1 includes a distance sensor 13 configured to acquire information on a distance from the work vehicle to each of a plurality of objects present in a field, a rectangle identification unit 41 configured to estimate a plurality of crop rows on the basis of the distance information and identify a rectangle whose opposite sides are adjacent crop rows of the estimated crop rows, a target setting unit 42 configured to set a target travel route of the work vehicle between the adjacent crop rows on the basis of the rectangle identified by the rectangle identification unit 41, and a position deviation calculation unit 43A configured to estimate a current position of the work vehicle between the adjacent crop rows on the basis of the rectangle identified by the rectangle identification unit 41 and calculate a deviation amount of the current position from the target travel route.
