Abstract: A vehicle control device causes a work vehicle to automatically travel in accordance with a target route set in advance. The generation processing unit generates, in a case where setting information related to automatic traveling is changed after the work vehicle starts automatic traveling corresponding to the target route, a target route with reference to a work-completed route along which the work vehicle has performed work immediately before. The vehicle control device causes the work vehicle to automatically travel in accordance with the target route.
